Why not wireless?

The numerous mainstream media articles on the NBN (and particularly the comments sections) are invariably littered with statements like “Wireless is the future”, “Everyone knows fixed lines are dead”, “fibre optics are being made obsolete” etc etc.

And no-one more than I would love that to be true. I’m sure we all would. The thought that we could obtain superfast data speeds without the need for wires is a tantalising concept. Unfortunately, it’s just not possible. That’s not to say wireless networks won’t continue to improve. Of course they will. But they will never approach the current or future speeds available via fibre-optic cables.

Wireless is a great complementary technology for deployment alongside fast fixed networks, and is also useful for delivering broadband to a small number of users in remote areas. But it is incapable of doing so in densely populated urban areas.

Let me make one fact absolutely clear from the beginning: Despite what you may have read from certain clueless commentators, there is not a single country or telecommunications company anywhere in the World that is attempting to replace fixed networks with wireless in urban areas, or even planning to do so in the future.

The concise explanation
  • Physical limitations prevent practical wireless speeds from approaching those available over fibre-optic cables
  • There is insufficient radio spectrum to allow wireless to replace fixed networks
  • To even partially overcome the above limitations, we would need to build over 75,000 new mobile transmission towers across Australia
  • Wireless network connections are prohibitively expensive, typically being 3-4 times more expensive, for less data volume and at a much slower speed.
The detailed explanation

Fibre Vs Wireless speeds

Fibre-Optics:

Commercially, fibre-optic cables are being used to carry data at speeds of about 2 Terabits per second (Tbps). Experimentally, trials are now achieving over 69Tbps over a single fibreoptic strand.  (A Terabit is 1,000 Gigabits or 1,000,000 Megabits).

While the NBN will not be equipped to deliver such massive speeds initially, like all fibre-optic networks it is highly upgradable should greater speeds be required in the future. Speed increases only require upgrading of the transmission equipment with the fibre itself being unchanged.

Wireless:

Current 3G and 3.5G wireless networks (eg: Telstra NextG) offer theoretical speeds of up to 42Mbps. However, practically that network falls to a maximum of about 8Mbps, even under ideal conditions. Experimentally the 4G/LTE Advanced consortium is achieving about 1Gbps (per cell), as is the competing WiMax consortium.

So let’s compare wireless and fibre, with all speeds converted to Gbps:

Experimental Current Theoretical Current Actual
Fibreoptic (per strand) 69000 Gbps 2000Gbps 2000 Gbps
Wireless (Per cell) 1 Gbps 0.042 Gbps 0.008 Gbps

As it currently stands, fibreoptics are achieving speeds that are 250,000 times faster than wireless. In the experimental stages,  fibre can carry 69,000 times more data than the entire bandwidth delivered by a wireless tower!

Other wireless speed limiting factors:

Contention:

Speeds quoted for wireless networks are per cell, not per user. The total speed must be divided amongst all the users on that cell. So unless a user has their own personal cellular tower, the quoted speeds can never be achieved. For example, if 100 people are sharing a 1Gbps wireless network, they will each only obtain 10Mbps.

Topography, distance and other obstructions:

While data travels fast and essentially unobstructed through the glass of fibre-optic cables, the same is not true of wireless. Every obstruction along the way obstructs wireless data. From buildings, to hills, to trees, to rain. Even the air itself slows the effective speeds we can achieve wirelessly. These are unassailable limitations of the technology and they are one of the major reasons why “42Mbps” wireless networks usually operate at a tiny fraction of that speed.

Clearly, there is no hope for wireless to offer speeds approaching current fibre-optic technology, let alone fibre speeds which are under development.

They say a picture tells a thousand words, so here are several thousand, comparing the speeds achieved using a fibre NBN connection to those using Cable, ADSL and 3.5G wireless networks:

The comparison above clearly demonstrates the practical limitations of the various technologies.

Below is a graphic showing the effect of distance, which is particularly important in a large country such as Australia:

The Spectrum Shortage

The biggest issue currently facing wireless data networks isn’t the obstructions. It’s another physical limitation: Radio Spectrum.

Every user added to a wireless network uses more radio spectrum. Every speed increase also uses more spectrum. For example, the 4G/LTE consortium reports that they can deliver a 300Mbps network using 20Mhz of spectrum per site. But delivering 1Gbps requires 100Mhz of spectrum per site (See page 12).

So why does it matter how much spectrum we use? Can’t we just add more? Well, no. Spectrum is a finite resource, which is already being stretched by the low volume of data being transmitted over mobile networks. It is also used by numerous other services, such as radio and television broadcasting and other radio traffic, which reduces the amount that can be allocated to wireless broadband services. The United States Federal Communications Commission chairman has stated that wireless broadband is already “in peril” due to spectrum shortages, while the CEOs of Vodafone and RIM (Blackberry) have stated that wireless broadband is reaching crisis point. Meanwhile, industry experts have advised that the spectrum shortage will be debilitating by 2013. And all these warnings are just assuming wireless broadband remains as a low volume complement to fixed broadband, not as a replacement for it. Even if additional spectrum is allocated to wireless broadband services, there simply isn’t enough radio spectrum in existence for wireless to approach fibre-optics.

A single strand of fibre-optic cable can carry 20,000 times more data than the entire radio frequency spectrum combined.

Mobile Towers

Even if the spectrum issue could be overcome, for wireless to deliver superfast broadband to all of Australia it would require a huge increase in the number of mobile phone towers, and we all know how popular they are!

Australia currently has about 10,000 mobile phone towers across the country. To build a 4G/LTE Advanced network that could achieve a similar level of performance to the fibre-optic NBN, we would need to build approximately 75,000 additional mobile phone towers (Assuming 10M premises, 1Gbps per cell, 6 cells per tower, delivering 100Mbps to 50% of premises simultaneously).

Of course, all of those towers would have to be connected using fibre-optic cable.

Isn’t the world going wireless?

There is a perception that everyone is changing to wireless, but they’re not. They are adding it. According to the Australian Bureau of Statistics, the number of mobile broadband internet connections grew by ~40% in Australia between 2009 and 2010. But the total amount of data downloaded over the wireless networks actually fell, despite the greater numbers. Conversely, the amount being downloaded over fixed networks is still increasing by about 50% every year.

South Korea, a country that already has a 100Mbps fibre-optic NBN, has announced that they are spending $US26bn upgrading their fibre network to a speed of 1Gbps, to compliment their WiMax (4G) wireless broadband networks.

Just as you can’t replace a regular oven with a microwave, you cannot replace a fast fixed network with a wireless one. The two are complementary technologies, not competing ones. To have a successful wireless broadband network, you must build it on the back of a fast, high volume fixed network.

What about cost?

The other big issue preventing wireless networks replacing fixed ones is the enormous cost difference between the services, despite the vastly inferior performance.

For example, the largest wireless broadband plan on the Telstra NextG wireless network is 12GB of data for $89.95 per month, where Telstra quote speeds of “between 1.1 and 20Mbps in metropolitan areas, with lower speeds outside metro areas”. (see here) By contrast, on the NBN you can get 20GB of data for $29.95 per month, at a speed of 25Mbps. (see here) For another $9.95, you can add a phoneline with all local and national calls for free.

So it’s possible to have an NBN connection and a phone, free calls, twice as much data at a higher speed, plus a smartphone with a gig or two of data (on a ~$45 mobile plan) for less money than a mobile broadband connection alone.

What about DIDO?

The ink was barely dry on the sketchy DIDO wireless white paper when the anti-NBN brigade began touting it as something which will imminently make the optical fibre of the NBN obsolete. So what is DIDO?

Well, right now it’s vapourware. There are no technical specifications, detailed explanations or independent tests of the technology, outside the self-published and extremely basic white paper linked to above.

DIDO is a series of grandiose promises from a small startup technology company in the USA, who are trying to raise capital after failing to generate interest in the concept. The promotor claims that the system can overcome one of the limitations of regular wireless technologies, being the massive speed reductions that occur as more users join the network. They claim that the entire capacity of the wireless network can be delivered to each user at the same time. Sounds rather unlikely. Is it just another example of Silicone Valley’s too-good-to-be-true Next Big Things?

You never know though, DIDO might do everything they say it can. But at this stage it’s very much in the early experimental stage. Right now, DIDO has only been tested in a laboratory with 10 users, and outdoors with 3 users. They claim from these tests to be able to scale up to 100 or 1000 users. I’m not kidding. On the basis of claims by a venture capitalist that this technology works in this limited environment, mental giants like Andrew Bolt are declaring the NBN to be dead and buried!

So let’s give DIDO the benefit of the doubt, and assume it can do everything they say it can, what would that mean for the NBN?

  • There is many, many years of research to be done. Scaling from 10 users in a lab to a network that can serve 13 Million connections is a huge task. Expect a decade of research.
  • There is currently no regulatory approval of the system, including testing alongside other users of radio spectrum. The US regulator has so-far refused to grant even an experimental licence for the technology.
  • DIDO doesn’t overcome any of the other limitations of wireless, such as distance, signal loss and obstruction penetration.
  • It has not been tested at all with moving receivers, and it has not been tested at long range except using ridiculously low frequencies of 3-5MHz, requiring the signal to bounce off the atmosphere, creating more potential interference and latency.
  • It has not been tested at all in a “cellular” system, which would be required to achieve fixed-network replacement.
  • Each DIDO base station must be connected to a datacentre by a fast internet connection (ie: Optical fibre). So even if DIDO works, it will happily plug into the NBN, just like WiFi.

So while it’s true that there is huge potential for DIDO if everything they say is accurate, it will be a long, long time before it will be commercially available. So how does this affect the NBN? Should we just sit back and do nothing until this particular Next Big Thing arrives? Then what? Do we then sit around for another 10 years waiting for the next one? Let’s also not forget that it still doesn’t solve some of the biggest problems of wireless communication.

It should come as no surprise then, that no telecommunication engineers or physicists have come out saying DIDO will make the NBN redundant. Even the developer itself only promotes DIDO as a cellular replacement, not a fixed network replacement. That job is left to the usual band of technologically-clueless commentators, who -as always- apparently know better than people who actually possess some qualifications on the topic.

    “Just as you can’t replace a regular oven with a microwave”

    Love the article, however wanted to let you know this is a poor technology. I have used a convectiion microwave oven to replace and oven, when I first moved out of home there was no oven so got the microwave which worked quite well for cooking roasts, cakes e.t.c.

    • NBN Myths says:

      Ahh, but that’s a convection microwave. ie, it gets hot like a regular oven.

      Anyway, the point is that there would be a few people who could replace an oven with a regular microwave. But for the vast majority, the two technologies are complementary, not competitive.

      • Tom says:

        Great article. Thanks. You nailed it with your term “complementary technology”. The two are not mutually excluding “alternatives”. I was blown away by your objective discussion on the options available today.

        If you are the future of NBN, bring it on.

  2. diaglyph says:

    Thanks for writing this. I never thought wireless would make a great alternative to fibre – it’s simply ridiculous. Wireless is fine for gadgets and mobile devices (iphones, ipad, hand held game devices, etc), but not for consistent “at home” connection or work connection.
    I can’t wait until NBN comes by my neighbourhood and replaces the idiotic copper connection that runs through the RIM in my area (and I won’t have to be subject to Telstra either!).

    • davidL says:

      You’ve never used a wireless router?

      • mitchells00 says:

        Wireless over a small distance (<50m) is MUCH more reliable than wireless over large distances, thanks to the inverse square law (a connection 10 times further is 1000 times weaker); not to mention the fact that the same dozen very wide channels are reused over and over in small areas transfer MUCH more data each than many thin channels over a wider area…

        The physics of radio waves are NOT in our favour when it comes to using them as data transfer mediums.

        • davidL says:

          Just to correct: 10x d = 1/100, and not 1/1000.

          Yes, I know that path loss is a sq law, like any other any RF engineer.

          It’s fair to say that wireless presents great challenges, but it’s also fair to say that we’ve taken up those challenges and are advancing the cause at a rate that was unimaginable back when “Group Speciale Mobile” was born.

          • Ross says:

            I agree. I remember being told the theoretical maximum that our copper could carry due to the noise levels. That was in 1992. We’ve smashed that maximum repeatedly since then, and the same is being seen with wireless. When no possible way to get higher throughput is visible, somebody finds one. And the key point for me, is that the bandwidth possible stays JUST ahead of our actual immediate requirement. Having terrabytes of bandwidth would be useless to me right now, and would be for years to come. By the time I need it, technology will have moved on, and I bank on wireless giving me what I need at that point, and not tied to one location either!

          • NBN Myths says:

            Wireless data is massively expensive compared to fixed line. That’s why most people have both. They use their fixed lines at home for the ‘heavy lifting’ of video, software updates etc, and they use mobile for low volume mobile use.

            There was no physical reason preventing copper form improving speeds, it’s just that the tech (such as ADSL) had not been invented. That’s not the issue with wireless. With that, we are bumping into physical limitations of radio bandwidth. Unless the laws of physics are re-written, there’s no hope that any wireless can ever approach the capacity of optic fibre, because the light spectrum is 20,000 times larger than the entire radio spectrum. And every strand of fibre can use the whole spectrum, but with wireless the available spectrum must be shared by every type of user in an area (radio, TV, CB, satellites, private radio networks), and by different carriers and users on each cellular network. So in practise, it’s a tiny fraction of 1/20000th the capacity of fibre.

            Wireless is only “just keeping ahead” of needs because it’s being artificially limited by price. Carriers know that they need to force people to limit their use of data on mobile networks to keep them from collapsing. 4G wireless is only as fast as it is because people can’t use it for high volume downloads because of cost. If Telstra gave everybody 1TB a month on their 4G network, it would slow to a crawl. By limiting people to a few GB per month, they can ensure that everybody can get a half-decent speed most of the time.

            And yet even with these artificial limits, 4G is not even close to the current capability of the NBN, let alone what it can actually deliver.

  6. art vandelay says:

    Ahhh the never ending story of “more is better”. In practice I could add rockets to my car and it will go much faster than the internal combustion engine, however I have no practical need to do so. While your article does call out the difference in theoretical maximum through-put it fails to address the point that the average user will have one connection per device and that will not require much more through-put than that used all over the country right now. Let’s face it, video bit rates of around 2meg sustained provide more than acceptable viewing quality for even 1080p screens. As long as compression technology continues to evolve, fibre will stay where it belongs, doing the heavy-lift backhaul to get the data to the mobile towers we will not be able to live without.

    • NBN Myths says:

      First, it’s not just “more is better”. Yes, that is a part of it and history tells us that required bandwidth and per-user volume will continue to grow, thereby requiring higher speeds. Both have been growing since the beginning, and are showing no signs of slowing down.

      Per-connection volume has been growing by at least 50% every year (compounded) since 2001, according to ABS stats and the Cisco reports. To think this will suddenly stop is naive.

      Telstra have just launched their “4G” mobile broadband service, and the largest available plan is a paltry 15GB per month. Clearly this is totally insufficient as a fixed-line replacement for an average user, when you consider that as at June 2011, the AVERAGE ADSL/Cable connection in Australia is downloading 47GB per month.

      Then of course, there is the price. That 15GB (at maybe 10Mbps) will cost a whopping $100 per month. For the same money on the NBN, you get 1,000GB at 100Mbps. 10x the speed, 67x the data for the same price. And yet you expect that every device will have a wireless connection. So in your World, that’s $100 per month for the TV, another $100pm for the desktop. $100pm for the laptop, $100pm for the iPad….. So far we’ve spent a total of $400 per month, for a total capacity of (maybe) 40Mbps and a total volume of 90GB. Who in their right mind would pay that much, when the NBN is so much faster and cheaper? Your utopia also ignores the fact that wireless is a shared medium, so the more users the slower it gets.

      The FACT is that there is not a SINGLE telco or country anywhere in the World advocating replacing their fixed networks with wireless in urban areas. Because no Telcos are stupid enough to think it’s possible. They understand that the physical limitations of the medium prevent it. That’s why Telcos everywhere try to offload as much data as possible to WiFi and the fixed networks, because cellular nets are already beginning to collapse under the tiny load they now carry.

      If you think 2Mbps provides sufficient quality for 1080p screens, then it’s time to visit the optometrist. A minimum of 5Mbps would be a closer estimate of reasonable quality using H.264 at 1080p. But resolutions will continue to grow alongside the size of TVs, and I suspect we;’ll be seeing HDR and 2160p resolutions, which will quickly absorb any advances in compression tech, and then some. But that aside, it’s not just about a single user, it’s about multiple simultaneous use.

      All that said, I agree that cellular wireless is something “we won’t be able to live without”. Which is exactly why it’s so important that we have a fast fixed network to do the heavy lifting of home and business use, leaving the cellular systems to take the low-volume convenience side of the market. It’s not The NBN OR wireless. It’s the NBN PLUS wireless.

      • Ross says:

        I see the two networks as complimentary too, but in a different way. Wired networks already do the heavy lifting perfectly well and will continue to do so on long hauls for commercial use. If we have fibre to the node, and the nodes are plentiful and close together, then wireless for the last leg should be a short run will minimised contention. NOW USE THAT FOR MOBILE TOO! So rather than having several competing commercial vendors like Telstra, Optus, and Voda, all consuming bandwidth over longer distances, we have a national infrastructure that pools all that bandwidth for maximised throughput, with minimised contention, and your phone battery life will improve too. If anyone doesn’t like the performance they get, they can seek a wired connection for their last leg (and see if they get any actual performance improvement anyway). I think most of the time the bottlenecks elsewhere, and the number of times they are accessing data away from their premises, will mean they have wasted their money,

        • NBN Myths says:

          Hi Ross,

          While it sounds nice in theory, there are a number of issues with your plan.

          In practise, it just won’t work. There is not a single country on the planet where such a network is being proposed by Governments or telecommunication companies. That alone should tell you something.

          Even if all the available radio spectrum were forcibly taken from the existing carriers and pooled into one network, it would not even come close to delivering the required bandwidth. Currently, wireless only carries about 6% of internet traffic by volume. And it cannot cope even with that tiny portion. Australian internet traffic volume is increasing by about 50% per year, every year for the last decade. The growth rate is actually increasing, and the capability growth of wireless technology is not coming close to that sort of an increase. So given that wireless cannot cope with 6% of today’s volume, how do you think it could cope with 100% of the volume in, say, 5 years? That would represent 7500% more volume than carried by wireless networks today. Even smaller cells could not allow a tiny fraction of that sort of capacity.

          Another practical issue is wireless base stations. NBN Co are only covering 4% of the population with wireless by building about 1500 towers, yet they are having huge amounts of trouble getting them approved. Imagine trying to install 60,000 towers. And no, you can’t put them at street level if you want decent performance. You’d need to at least install them on a pole.

          Then there is cost. Wireless data is incredibly expensive, because everything to do with it is expensive. Buying 15GB of data on Telstra 4G costs $100 per month, but for $100 a month on ADSL, cable or fibre gets you around 1000GB of data.

  7. The fibre vs ADSL vs 3G graph is fantastic! Any chance of an updated one with 4G speeds?

    • Jan says:

      Haha, no it’s not. They have clearly hand picked the speed results that benefit them.

      My ADSL2+ speedtest sits at 17Mbps and my 4G phone connection is 40Mbps. I only had 2 bars of signal strength when I did the test.

      On my ADSL2+ I can stream 1080p video with surround sound audio in much faster than real time. More than good enough for video conferencing and this hyped up healthcare at home.

      5G is coming by 2020 and is already doing 100x faster than 4G.

      More is not better. Better isn’t even better otherwise we would’ve had Betamax instead of VHS, OS2 instead of Windows etc etc.

      Consumer trends is to use mobiles and tablets with sim cards to connect. Ignore this at your own peril.

      • NBN Myths says:

        1. The average speed of ADSL2+ in Australia is 8-9Mbps. You might well get 17Mbps, but most people don’t get anywhere near that. ADSL speeds depend on distance from the exchange, so you obviously live close by. Lucky you. What about the rest of the population?

        2. Your 4G speed is currently that high because there are so few people using the 4G network in your area. Like all wireless technologies, the available bandwidth is shared. Each cell can deliver 150Mbps, so for you to get 40Mbps means that there were only 2-3 other users on the cell at the time. However, wait until there are 100 users all trying to share it. This is already happening in the USA, and 4G speeds have dropped to under 10Mbps in metropolitan areas.

        3. You ADSL2+ can only stream 1080p downstream. You cannot send it upstream, because even the maximum theoretical speed of ADSL2+ upstream is 1Mbps. So it is not possible for you to have a 1080p HD video conference, because while you can receive a stream you cannot transmit one.

        4. There is no draft 5G standard in existence, let alone one that is “100x faster than 4G and coming in 2020″. In fact, Ericsson recently said that there is little prospect of a 5G in the foreseeable future, because they have no way to improve substantially on 4G. There is LTE-advanced coming soon, which offers about 6x more speed than 4G (LTE). However, it uses considerably more radio spectrum, and will therefore suffer the same issues of 3G and 4G as more users connect.

        5. The consumer trend is to add mobile connections, not to replace their fixed line connections with mobile. This is clearly evidenced in both the ABS stats and those in the Cisco annual reports.

        I suggest you do some more fact-checking, Jan.

        • davidL says:

          Personally, I see reliability as the biggest advantage of last mile fibre over FTTN or wireless. To compare the theoretical speeds of fibre and wireless is rather spurious IMHO. What is valid is to compare speed with requirement. The assumption being made that requirement for future user bandwidth can only be met with fibre (FTTH) is far from correct.

          FWIW I spent 12 years as a wireless network planning engineer with a large telco, and that included 2G, 3G, and 3.9G (OFDM)
          I can say with great confidence that wireless has a big future ahead. Not just because of more radio spectrum but also because of MIMO, SDR, battery technology, processing power etc. The future isn’t large telecommunications towers in every street but rather it’s pico cells and wi-fi hot spots which are small enough to be invisible. Wireless capacity isn’t just proportional to RF spectrum, it’s proportional to the number of cells. More cells = less users per cell = higher throughput, and this is exactly the means by which wireless networks have grown capacity over the past 30 years. Naturally you still need fibre backhaul for a wireless RBS but that may or may not be NBN co infrastructure. The big telcos own their own SDH fibre transmission networks to support their wireless networks.

          In summary, yes, NBN FTTH is probably desirable for reliable internet in the home and yes it does provide future proofing for bandwidth requirements yet to be conceived but I also have confidence to state that the sky will not fall in with a coalition victory and a FTTN solution. FTTN’s can be deployed much faster and with VDSL it will provide for bw requirements as they exist today, and together with wireless can provide our needs for a couple of decades at the very least.

          For me personally it’s not a big election policy. A labor win and FTTH is nice but I will be waiting until about 2022 before the NBN co trucks come to my suburban street. In the meantime I have wirelss 4G and very slow ADSL to see me through.

            ” also have confidence to state that the sky will not fall in with a coalition victory and a FTTN solution. ”

            4 months on and the sky fell in over the Coalitions FTTN solution. :P

          • Tom says:

            @ Joey Joe Joe , correction, 4 months on it fell in on Labor’s lies about cost and roll out delays. Labor promised it in 2007 and in 2013 was still making excuses and spinning. The joke is on Labor.

          • NBN Myths says:

            To be fair, the 2007 NBN was very different to what eventually happened. It fell apart because then Telstra management (appointed by the Coalition) refused to participate in the planned FTTN network in 2009. That left Labor with essentially no option but to bypass Telstra’s copper with fibre. So began the FTTP NBN in 2009, with various trials across the country. Full rollout couldn’t begin until the (new) Telstra management agreed to infrastructure access. These negotiations took a long time, greatly delaying the FTTP rollout. Telstra’s poor efforts to make the infrastructure NBN-ready (asbestos removal) further contributed to delays. The other portions of the NBN (Transit, wireless, satellite) are all on time and budget. Even the Coalition’s review document says that FTTP can be done for $41bn capex (Not including the $3bn in extra contingency fund they added), and be complete by 2023. That’s only $2bn and 2 years later than Labor said.

            By contrast, the cost of the Coalition’s FTTN network has increased by 33% in just 3 months, and the “25Mbps to 100% by 2016″ promise has been cut to just 43% by that time.

            It should also be noted that the Coalition’s NBN cost and performance promises are based on getting free access to a network they don’t yet own (or have access to), don’t know the condition of, and have not conducted any testing on. What could possibly go wrong?

          • Tom says:

            @NBN myths, it remains that Kevin07 made a promise he could not deliver on. And now you are admitting that everyone knew Telstra was an obstacle to that promise.

            If Telstra (Coalition appointed?) was a show stopper, why did Labor promise it?

            Leaving out who appointed Telstra’s management, you are glossing over the not so trivial issue of Telstra share holders. Why should Telstra be coerced to give up a commercial advantage just so Rudd and (hardball) Conroy can look good?

            In fact, Labor emulated Churchill at Gallipoli where the original plan was stupid. Now they want someone to blame.

          • NBN Myths says:

            You’re making a straw-man argument Tom. It wasn’t known that Telstra would be a show-stopper before the election. That wasn’t discovered until they failed to submit a complying bid for the FTTN RFP. As the Coalition have now discovered, it’s not really possible to negotiate deals before you’re in Government.

            Management change aside, the Coalition now find themselves in almost the same position as labor had in 2007: They need access to Telstra’s copper network in order to enact their policy. Worse, they assume that Telstra will give them access to that network at no additional cost. Speaking of Telstra’s shareholders….If you were one, how would you feel about Telstra giving away what is (now) a valuable asset, for nothing?

            In case you haven’t noticed, the Coalition have also made a promise that they cannot deliver on . Turnbull and Abbott made a “bulletproof” promise before the election that they would deliver 25Mbps to 100% of the population by 2016, at a cost of $30.4bn. Here we are 4 months later, and the cost has gone to $41bn, and the coverage has dropped by 57%. And even those new targets are pure guesswork, since they admit they have done zero testing, have made zero allowance for copper access cost and have zero data on network condition.

            If Labor’s original FTTN plan was “stupid”, then why is the Coalition’s current plan any less so? And how are the Coalition’s delivery promises any better, given the revelations of the last week?

          • Tom says:

            @NBN, are you saying that the fact that the coalition appointed Telstra had nothing to do with Telstra’s intransigence to Rudd and Conroy? If so, why mention it in your post?

            I don’t buy Kevin07′s ignorance of Telstra’s stance as an excuse for making an undeliverable promise.

            If Telstra were going to oppose whichever side was going to upset their monopoly, why didn’t Kevin07 do some reconnaissance?

            (The same reason Kevin 07 promised to end the health “blame game” by transferring state control of health to the Feds. Wall to wall Labor, but state governments were never going to hand over their empires to Kevin07. No reconnaissance there either. It was a fatuous promise from the “whatever it takes” spin doctors.)

            Abbott’s only excuse is that he was locked into the hype and expectation that had been created by the “tomorrow-world” vision of NBN. I half agree with you, I don’t think NBN will deliver under either government.

          • NBN Myths says:

            I think that the former management of Telstra (the so-called three amigos) were much of the reason why FTTN never went ahead. However, there was no public indication from them prior to the election that they would not participate in the project.

            If Abbott was serious about leading a truthful Government, he would have made accurate statements about the cost, capability and timeframe of his alternative project. He failed. Nobody with a modicum of knowledge on the topic thought their “25Mbps to 100% by 2016″ was even close to being deliverable. Yet he held on to it right up to (and beyond) the election. “Being caught up in hype” is hardly an excuse.

          • Joey Joe Joe says:

            @Tom – “Abbott’s only excuse is that he was locked into the hype and expectation that had been created by the “tomorrow-world” vision of NBN.”

            Your excuse for 41 billion on a half-baked plan is that Abbott is gullible? It’s got nothing to do with the fact it is a reasonable, affordable (<1% GDP) investment for the future does it?

            And within that "hype and expectation" he is willing to spend $41 billion on a half-baked promise? …that half baked promise which coincidentally (inevitably) will have to be upgraded, at a bloody cost, to what had already begun rolling out?

            Not to mention pouring billions into HFC – which again… will have to be replaced soon enough.

            I wish you guys would hold the same standards for liberals as you did for labor… you even called labors 2007 plan stupid… which again coincidentally is the Libs 2013 plan.

            If labor's FTTP plan, FYI under a liberal-appointed NBN co board (eg Ergas), blows out by 30 million and 3 years its apparently/ obviously Labors fault.

            If the Liberal's own plan ( The FTTP 25%, FTTN 30%, FTTB 12% & 'no upgrade for you' HFC 30% plan) blows out by $12 billion and fails to meet the "100% guranteed if elected" promises by a whopping 57%… while claiming it will still be done on time…. i guess under a liberal-appointed NBN co board it is again labors fault?

            Not to mention the stupidity in essentially cutting 30% from the "NATIONAL" broadband network while shouting "look – we saved 30%!" and instead upgrading the technology used under foxtel.

            FFS – each parties are as useless as the next…
            hold the same standards to both and stop playing ignorant to the fact the liberals manipulating the data and lying through their teeth as they see fit.

          • Tom says:

            Unfortunately, it was Rudd and Conroy who created the hype in the first place in a clever clogs election manouvre to wedge the LNP.

            If Abbott went to the election saying something like “I will dump NBN because it is a non-delivering political motivated white elephant (which is the truth), the LNPs got howls of ill-informed mob driven hysteria about being “luddites” and “sending us back to tin cans on strings”.

            It is interesting that none of the techos on this site ever passed comment on Conroy’s total lack of IT knowledge, yet howled like hyenas at someone Turnbull on IT understanding. Conroy’s argumentative, throw money at the noise makers, “whatever it takes” style shows where most of the pro NBN advocates lie – on big money, empire building, power and rolled-golled geek solutions. Most are not objective and have a lazy presumptuousness and sense of entitlement to taxpayers’ money. Your NBN? Of course you prefer Labor.

            Joey, Joe Joe, it is a bit rich talking about “half baked plans” when Labor refused to release any rigorous detailed costing / revenue projections for public scrutiny for the first 4 years of NBN. Even then, they repeatedly lied about the actual roll outs and their projected roll-outs were the stuff of snake oil salesmen. I am surprised any of you still seek to justify Labor against the LNP on such matters?

          • NBN Myths says:

            I wonder if you comprehend the irony of using the internet to claim that a project to deliver better internet is a white elephant?

            A white elephant is something that’s neither popular nor useful. Yet (outside the conservative right), there are few saying that about the NBN. The average takeup rate after 12 months availability is about double the projection (42% v 20%), with some areas on 60%. That compares to 3% for ADSL after 18 months of availability after it was launched. Additionally, the takeup rate of the top 100Mbps plan is also about double the forecast breakdown. Every public poll taken on the NBN has found it’s an extremely popular policy, with a majority of Australians supporting it. If that’s what you think a white elephant is, best go look at a dictionary.

            Few people criticise Turnbull for being a tech incompetent. That jibe is usually directed at Abbott, and he admits it. Conroy may well not know a great deal about the technology, but he has the vast majority of sector experts on his side. He accepted advice from the experts in the field, and made a policy on that advice. Abbott and Turnbull went the other way, and before their policy has even begun, it’s already starting to unravel. It seems to be a standard fault of the Coalition: Ignore the experts. They ignored the economists on the economy; climate scientists and economists on climate change policy; ITC experts on ITC policy.

            The NBN’s cost/revenue projections were released in the first NBN Co corporate plan, which was released in December 2010. About 18 months after the FTTP policy was announced. The actual rollout figues have always been accurate. The projections should have been possible, once the volume rollout commenced, and they are currently doing quite well. They were (and are) well within international standards for similar projects. Even the Coalition’s review policy says that FTTP can be completed by 2023, which is only 2 years later than Labor promised.

            Would you care to explain why the LNP are performing any better on this matter? The Coalition’s own NBN review says that both plans will take 2 years longer to complete than the respective parties promised. It also says that Labor’s FTTP/wireless/sat version can be done for $54bn peak (20% over Labor’s promise), while the Coalition’s FTTN/HFC/FTTP/wireless/sat version will cost $41bn (33% over the Coalition’s promise).

          • Joey Joe Joe says:

            @Tom – in case you did not notice … my last point was each party is as useless as the next – all I am saying is hold the same standards to the liberals as you did labor.

            “@NBN myths, it remains that Kevin07 made a promise he could not deliver on.” But Abbott’s promise ( to those in the know – a blatant lie) you still feel the need to come up with every excuse under the sun as to why his BS is actually labors fault.

            Politics is politics – each party as BS as the next. My argument here is in the technology… but that is some how lost in the Anti-Everything Labor Rhetoric being spewed here.

            The ONLY thing that is ‘set in concrete’ in this debate is the stupidity of FTTN over FTTP… and pouring billions into HFC . The only thing that is guaranteed to work for everyone is going all Fiber – not ‘ a bit of this, a bit of that – depending on conditions/ the current state of the copper’. 93% FTTP by 2024 is not a farce – and I bet if the liberals actually focused on it – and not manipulate the data to support their own political agenda – they would estimate it to be completed “sooner, cheaper and more affordable”.

            By 2020 South Korea (A+ rating) would be 70% FTTP – that is roughly equivalent to double what 93% is to us. New Zealand (AA raiting) is expecting 75% by 2019. Argentina has been developing FTTP in its capitols since the year 2000 – credit rating CCC+.

            And what are we as a Triple A country expecting by 2020? 22% of 25 million people because we are apparently too poor to do it properly now. However we are still capable enough to install 60,000 nodes around the country – and then pull them out and throw them away when we again have to upgrade. We are also somehow rich enough to pour billions into Foxtel’s HFC.

            Why are we putting 40 billion dollars into a plan in which by 2016 47% of premises will be receiving speeds in which they should have been theoretically receiving 10 years ago via adsl 2? It’s the copper that slowed it down then – its the copper that is the problem now, the reason we need a new network in the bloody first place – and in its further degraded, rotting, pathetic state it is going to be the bottleneck and downfall of anything FTTN in 2020.

  8. Tom Amsugo says:

    I really hope you can present this excellent article to the next LNP National Conference.

    One thing some of your readers dont realise is that with higher speeds, services like video conferencing and familty video phone calls become the norm for day to day communications. To be effective this requires equal download/upload speeds, something current ADSL plans throttle so upload speeds are slower.
    I have heard this is something to do with the International Overseas Cable consortium, owned in part by Singtel/Optus and Telstra, charging higher fees for upload data.
    Can you clarify if the consortium is a party to an NBN deal for connections to International traffic and will they allow equal two way speeds at normal charges.

    • davidL says:

      Video conferencing is supported with UMTS 3G and 4G wireless and has been available to most people since about 2006. Oddly enough, people haven’t embraced it and globally there’s been a further fall in video traffic over the past few years. In spite of heavy promotion it’s non-use remains an anomaly.

    Love your work. It was a real eye opener. I hope the people can get the facts before the next election or we’re doomed.

  10. pm says:

    A little knowledge is a dangerous thing “nbnmyths”..it is apparent you are not an expert in the matters you profess and you ignore relevant aspects of the information you present which creates bias;

    1.You compare the “experimental” speeds of “Fibreoptic (per strand)” with the current cellular technology, i.e. 69Tbps to 1Gbps.

    2 You don’t mention that the experiments quoted require hundreds of lasers or expensive ($50k) water cooled research lasers to achieve these speeds. Let alone that the technology to modulate these setups requires a full 2m cabinet of electronics. You will NEVER see these speeds at home. It’s the “laws of physics” as Conroy likes to say repeatedly.

    3. You clearly have no idea where the technological, theoretical or “experimental” limits lie , what they represent and why.

    4. The NBN is a network with many inherent limits, you cannot simply assume that a speed achieved in an experiment is technically feasible, let alone economically feasible. Did you know that there are different types of fiber with different transmission and dispersion characteristics and that the lasers used at the premises are matched to the fiber?

    Realistically over time the NBN, despite the massive investment, will become relativily obsolete – meaning that it will need significant upgrades to support the latest technology. I believe the notion of anything being “future-proof” is the most dangerous myth. It encourages over-investment in today’s (or yesterdays) technology while discouraging organic replacement.

    The basic problem is not technological but economic. Technology is invented and becomes cost effective when there is consumer demand.

    Broadband prices are too low to cover the replacement cost of the infrastructure – due to the cost benefit of the copper network which was already a sunk asset at the birth of the Internet. Historically, either infrastructure was subsidised or technological progress eliminated the capital bottleneck.

    It is unfortunate that the choices that may be available to us are now so politicized. Let’s hope that reason prevails.

    • NBN Myths says:

      I’ll ignore for a moment the rather large conflict of interest you have, working for a company that promises “Metropolitan Scale Gigabit Wireless Broadband Networks”, and concentrate on the content of your comment:

      1: Commercial Gigabit cellular is no more “current” than 69Tbps over fibre is. Especially considering this page was written a year ago.

      2: No I didn’t mention any of that, because I don’t see why it’s relevant. It’s experimental, of course it’s large and expensive. Although I too doubt that we will see 69Tbps bandwidth to homes in the foreseeable future, one should never say never…. Who knows what technological advances are around the corner that will require such bandwidth, and what innovations will enable it to be mass-produced. The fact is that fibre can deliver it if required. You cite the fact that it requires a “full 2m cabinet” to deliver. So what? The computing power in the cockpit alone of a Boeing 777 wouldn’t have been able to be carried by a Boeing 707, 30 years earlier. If you had told Corning 40 years ago that they would be selling fibre to install gigabit connections to almost every home in Australia today, they’d have laughed at you. 60 years ago, IBM thought there was a world market for 5 computers. Need I go on?

      3: If you say so.

      4: Yes, of course it has limits. All networks have limits. Yes, I do know there are different types of fibre.

      Rest: Yes, over time parts of the NBN will become obsolete. But the largest cost (the installation of the fibre itself) is the most future-resistant option available to us. That fibre will in all likelihood satisfy our needs for the next 50 years or more. Conversely, look at wireless. In the last 10 years alone, how many times have the cellular carriers replaced their wireless infrastructure? Twice? Three times? Four times?

      Perhaps you’d like to suggest what technology the NBN should use, or how it should be done differently?

      • Tom says:

        Most people putting a case have a bias, not necessarily a conflict of interest. Or are you trying to gag any comment that does not accord to your own world view.

          NBN Myths writes;
          “….working for a company that promises “Metropolitan Scale Gigabit Wireless Broadband Networks”

          Why do you think NBN Myths wrote this comment when it is not mentioned in the post above?

          Is it because it was mentioned in a different post?
          Is it because NBN Myths has conversed with this poster before?

          I’m sure if NBN Myths was trying to ‘gag’ the above (or any) poster, he would just ‘moderate’ them (as Bolt and Jones do), or delete the comment. That would be ‘Gagging’.

          In saying that I don’t think you understand the realities of the situation. We have the opposing party saying that they can build ‘The NBN objective’, and do it ‘cheaper and faster’, yet ‘pause’ it.

          Mr Turnbull has also suggested that he has ‘engineers’ that support his opinion, however has failed to illustrate who they are. The closest thing we have gotten to identity was a tweet yesterday that suggested:

          “Malcolm Turnbull‏@TurnbullMalcolm

          @topher_1976 you should get in touch with most of the world’s telcos who would not agree with you.”

          By that very statement he thinks that FTTN is suitable for Australia. One can always add in to the argument that FTTH “might be suitable for ‘select’ locations inside a ‘dense’ population centre, with ‘good’ copper, as a ‘short term’ measure.

          Alas, he doesn’t say that.

          He could also suggest that HFC, is suitable, if you ‘bought’ Optus and Telstra networks (and any others), and ‘merged’ them, and then spend ‘billions’ on them (and connect the streets and houses and appartments that both Optus and Telstra missed), as a ‘short term’ measure.

          But alas, he doesn’t say that.

          He say’s:

          We can build it ‘cheaper and faster using a mix of technologies’, and his boss says ‘It’s a white elephant’ that ‘needs pausing’.

          Tom I’m unsure if you have ever looked up White Elephant in the dictionary, however, if the NBN was one, you wouldn’t want to ‘pause’ it.

          This conversation has become (and always was) very political, this is why peoples posts often resort to ‘liberal vs labor’ position. (Hell, the NBN FTTH was actually the Nationals idea!! Part of the coalition!!!).

          One has to remember, if the opposition government has any credibility with what they are saying, they would release details.
          And details that would suggest, to get FTTN to have any sort of decent speeds, they would have to replace the remaining copper, which means manpower. And 75% of the current build is currently manpower. So why would you replace copper with copper, when you could replace copper with fibre?

          Australia is a country of the Victa Lawnmower and Hills Hoists.
          We have a distance issue unlike any other country. A distance issue that greatly hampers FTTN without significant repalcement unlike other countries. (NZ ditched if for that reason. It didn’t deliver speeds as promsed).

          There are 3 key points that one needs to remember when assessing the NBN rollout.

          *NBNco is trying to get rid of Telstra as a monopoly Wholesale and Retail provider. By creating one ‘Wholesale’ monopoly. that all the ‘retail’ guys on can compete like crazy on.

          *FTTN is only good in select areas, including MDUs. Which negates a whole chunk of the country. And then has an ‘up to’ speed issue depending on the exact length of the copper. Up to around 80mbps, as opposed to 1000mbps..

          *HFC, needs billions spent on it. Of which both Telstra and Optus have publicly stated they don’t want to spend. They have stated don’t want to upgrade the network. It was designed for TV, not internet. And it will return to TV once NBNco has built in it’s areas..

          If you punch the numbers (as many in the industry have), there is no way whatsoever, that the coalition can deliver the ‘NBN objective, quicker and faster’.

          And there is even less of a chance that they could do so if they ‘paused’ it.

          Especially when they have also stated ‘we will honour existing contracts’ (there is a 5 year contract for fibre alone…..)

          So although you might not agree with the way NBN myths holds his dialogue (and, with due respect, if you were abreast of the situation, you would understand why he holds his position), it isn’t without cause.

          The coalition haven’t delivered 1 ounce of data that suggests that the bulk of the network can be delivered any better than it is currently, and do so cheaper and faster.

          People ask them every day, to provided details, and they just don’t. Because for the most part, there is nothing to provide.

          There just isn’t any data to support their position. And most abreast of the situation understand this. And they have to refutre the claims on a day to day basis, To their friends, to their collegues, to their family, to the press. Commentators like Bolt and Jones (and (Malcolm and Abbott) tell the people there are other options. When if fact, if other options were taken, we’d still have a very antiquated network for decades to come.

          The network being disigned, has options for gigabit speeds. Any further upgrade upon that, just needs the switches on either end of the fibre changed.. This covers the 93%, with the ability for the network to naturally grow to cover move of the country, as the copper did around 50 years ago…

          And if you follow NBNmyths projected speeds graph (laid down by Jakob Nielson) you will see we will need gigabit in the not too distant future.

          And that is why we are building the FTTH NBN.
          As all the other options won’t suffice..
          And we get a new network to boot
          And we fix the Telstra Vertically Intergrated Monopoly issue created by the Howard government.

          All in one go.

          Sincerely

    You need to amend you statement in red type about that not a single telecommunications company in the not a single country or telecommunications company anywhere in the World that is attempting to replace fixed networks with wireless in urban areas, or even planning to do so in the future.

    Telstra is attempting to put a 31.4 metre 3G wireless tower in to a semi-rural area at Samford to provide services to over 5000 in the area. We are only 25kms to the centre of Brisbane’s CBD, and the old copper network is horrendously insufficient. But they are proposing this as a solution. Perhaps you could look into this?

  13. Scott says:

    Following on from Sam (posted 21 July, 2012 at 10:45 am). Sam says Telstra is attempting to replace failing copper with wireless in Samford. Well they’re doing the same thing out west of Sydney too.

    My parents live quite literally next door to the subexchange there. We’ve always had perfect 24mbit down speed etc. Suddenly the speeds have dropped to being a touch faster than an ISDN connection. Called Telstra and they explained that the exchange is having problems however they won’t be fixing it as it’s become obsolete. They then moved my parents onto wireless, sent them a 4g modem etc. Asking around, they have done the same to a few other neighbours in the street.

    Telstra seems to be moving people off fixed line onto wireless. So I believe that we now have a Telco doing the whole wireless thing. I’d also like to point out that they put my parents onto the 15gb plan however at a massively reduced price (from the $100 per month cost I read in one of the comments here). I believe they are paying $30 per month. The speeds seem really good tho, I believe they are seeing an average 12mbps down (for email, facebook and booking holidays this is overkill haha).

    Anyway what do you think of Telstra trying to undercut the Labor NBN by moving people onto wireless? Does this make the FTTH essentially wasted money if they’re pushing it to houses that will not even use the line at all? I personally wish that wireless could be used right now as an FTTH alternative (if it could reliably achieve speeds of 100mbit) but obviously it needs a bucket load of investment before wireless gets to those speeds (reliably with multiple users).

    Some good info in this article but still not enough to sell it to me, I personally don’t like the idea of a government run and controlled internet (especially with Labor in charge with their net nanny filters and their poor project management track record) and regardless of peoples beliefs on data usage I still think FTTH is oh so much overkill for the majority of the population.

  14. Anthony Wasiukiewicz says:

    No, they just aren’t fixing the exchange as it’s likely in your case it will be no longer needed (the internal equipment at the least).
    Telstra have a USO agreement (becoming TUSMA) to provide a connection to everybody.. And obviously, they have to reduce the price to stop an outcry.

    There is no way Telstra could continue to do this on a broad scale.
    And until the 700mhz spectrum is released in 2015, they are unlikely to be able to do this on a broad scale. And even then, capacity will be limited.

    Then you have to ask yourself the question, Why would people accept such a ‘restricted’ service, once they have access to NBN fibre for around the same price?

    You can guarantee that Telstra won’t be able to keep the prices that low to make a profit.

    “Some good info in this article but still not enough to sell it to me, I personally don’t like the idea of a government run and controlled internet (especially with Labor in charge with their net nanny filters and their poor project management track record)”

    There is more to this than you read in the papers.
    Labor’s track record is actually pretty good sans boat people (though you would never read about it in the papers).

    Have you observed how many policy changes ‘Federal’ Labor has managed to get through even with a ‘minority’ government?

    If that doesn’t say anything, than I’m not sure what does.

    I’m in SUBURBAN Brisbane – i guess that is classed as an URBAN area – I am 26km from the CBD and 8km from another city of 300,000 and the NBN have clearly stated that we will be having FIXED WIRELESS – not fiber.The copper adsl network is already rotting away and i have had no phones for 8 weeks , so you are right they are not replacing the copper network with the NBN , they are just letting it rot away.The FIXED WIRELESS is almost line of sight ONLY due the very high frequency spectrum it uses , and the fact that we are in a hilly area requires an outside antennae.This is another risk if there is a lightning strike or bird damage. Issues we already regularly have with our tv antenna as it is a high lightning risk area..Some people may not get any signal at all if they are behind a hill and will have to go satellite.We can also look forward to yet more ugly towers , whereas the present copper is mostly underground.The NBN is so slow to rollout it will be obsolete before it is even completed. I predict a change of government in 2013 and the NBN will be nothing like it is now.

  17. Wouter Wurth says:

    Before 1999 we had 64k connections that dropped out frequently and downloading a large file was a stop start all night affair. At the time the technology was a miracle to me. We have come a long way.
    Optus came with new coaxial cables which were much more reliable and still today it is Telstra that brings the internet into my house with the coaxial cable.
    I have never had ADSL1 or 2 but again a miracle invention that enabled copper telephone wire the carry much higher speeds. My experience with ADSL is away from home at friends or clients and when I travel. As a rule I am relieved when I come home and use my own pc and the cable and find that everything works.
    My mobile is pathetic and I only use it rarely for the internet. The iphone is better but still tedious.
    My system works at 18mps currently and is quite good. The NBN has not prioritised my area because of the relative high speeds available to us and rightly so focuses on connection to remote towns.
    AS soon as the NBN fibre optic comes near my house I will sign up immediately as I have always done in the past and embraced the best available. In my opinion the fibre optic, another miracle invention and the back bone of all large computer networks and communications networks is clearly the future.
    Wireless inside the house is handy but most of my serious connections run through cat5 cables or via the power points.
    Politics and infrastructure. Internet is much like water out of a tap, stormwater systems, electricity supplies, gas supplies and is part of modern day life and put the world into your house. Infrastructure is paid for by the nation and in the end by the users. Labour Party will think in terms of everyone, young and old. Liberal will only think about the people that can afford it, in fact they do not want to have anything to do with infrastructure and let commercial forces sort it out. The Capitalist model. The only reason why they have any comment is because they are in opposition and all of it is negative and waffle. There is no vision from the coalition and if it was up to their foresight we would still be cranking our telephones.

  18. David Adkins says:

    You mention costs to the end-user; why not an analysis of cost/benefit to the mug tax-payers who have to pay for this white elephant – $40bill (minimum) and off-budget?

    • Anthony Wasiukiewicz says:

      It is off budget for a reason. Because it makes sense. The current copper network costs about $1billion a year to maintain, and will likely cost more into the future given it’s age. This cost is incorporated into your Telstra end user pricing. As in, your bill. The bonds issued to build NBNco have interest applicable. This is the cost the Taxpayer has to pay in the interim until NBNco inevitably makes a profit. This ‘on budget’ ‘loan repayment’, starts off around a couple of hunderd billion in the first years. It then scales up to around the $1.5 billiion mark, before is scales back down again to zero as revenues from the network come in and are returned to the government coffers. Basically what we are talking about, is that you are leasing a car at $400 pcm for example, and the cost of leasing that car (Telstra) is about to rise. So instead of paying Telstra more (the car lease place), you then take out your own personal loan to buy your own car. The cost to buy your own car is close enough to on par as you were already paying the company you were leasing from.
      In laymans terms, the government kicks in a bit of on budget money to get NBN started (because the copper is ageing and getting unreliable for modern day communications). We then pay nearly the exact same amount of money to get a brand new network, that we would have been paying anyway to maintain the old one.
      If you look up the definition of White Elephant through google, you will see it actually describes the coalitions attempt at a policy.
      I hope that makes sense?
      If not, please don’t hesitate to ask for clarification on any point.

    • NBN Myths says:

      David,

      The premise of your question is wrong. The “taxpayers” aren’t paying for the NBN, they are only guaranteeing the funding until the user revenue pays back the debt. Ultimately, it is the monthly subscription fees that pay for the entire NBN, plus a 7% return on investment. This is essentially the same way the current copper network was built by the Government-owned PMG/Telecom/Telstra.

      The NBN is not off-budget, it is treated as an investment on the budget rather than expenditure. This is in line with standard accounting practise, as has been accepted as such by both economists and Malcolm Turnbull.

    For a so called policy document, it’s incredibly light on technical detail and heavy on attacking the Labor NBN.

  20. Mickey says:

    Zzzz… what a load of self-serving gas.
    There are many more wireless technologies than 3G/4G and WiFi.
    Specifically for this rant – spread-spectrum gig capable short-haul, femtocell based technologies (SSFC).
    Use the opposition proposed Fibre-To-The-Corner (FTTC) – then serve a limited number of (typically ~100) endpoints from each corner served with SSFC to guarantee service / performance benchmarks.
    These ‘micro’ cellular wireless connections have limited footprint and guaranteed capacity between overlapping cells. Your TV, internet, phone and mobile – all use this bandwidth directly or through your residential SSFC gateway (SSFC router). Walk or drive out of the house – and into another cell – and your (TV, internet, phone and mobile) are still connected as you travel to wherever – move to Cairns or Perth, and your gateway goes with you to the new house – V3x and other mobile technology platforms are supported with a mobile SSFC gateway (like a 3G/4G mobile router).
    Existing routing and network technologies support this today at speeds well into the specs promised by the NBN.
    No physical / trench / overhead last mile connectivity at all – just your NBN-SSFC subscription wherever you are.
    But will it feed the political cronies ? Perhaps not – we’ll need a new bunch of bloodsuckers.

    • Mickey says:

      Oh – by the way – due to the relatively short range coverage, and low-power/frequencies used – the suggested SSFC technologies do’t require a *tower* – simply a *small* antenna array slightly above ground level – the whole cell around the size of a single-door refrigerator.

    • NBN Myths says:

      Perhaps you’d care to provide a link to a specific product (with specifications), which you believe could provide the required capability? Also, if you could provide a list of countries where this technology has been, or is currently being, deployed.

      I look forward to receiving the link and list…..

      • Mickey says:

        Thanks – with a quick search – here are some of the more recent references… One of the least documented topics I could find on the net (my earlier references weer to technical journals I stumbled over during other work) the key phrases seem to be WiGig, Fi-Wi and Fibre-over-Wireless (FoW).

        While there are manufacturers mentioned in this list – it seems some of the products I’ve seen demonstrated may still be in “defence hands”.

        (1)
        Main article: IEEE 802.11ad
        IEEE 802.11ad “WiGig” is a published standard that is already seeing a major push from hardware manufacturers. On 24 July 2012 Marvell and Wilocity announced a new partnership[17] to bring a new tri-band Wi-Fi solution to market. Using 60 GHz, the new standard can achieve a theoretical maximum throughput of up to 7 Gbit/s.[18] This standard is expected to reach the market sometime in early 2014.

        • NBN Myths says:

          OK, so your links go to:
          A list of projects of various old/current wireless technologies, deployed in a variety of small LAN environments such as businesses and schools.
          A link to a draft paper from 2010, summarising the research that has gone into mm wave wireless networks, but not covering anything that is actually available for the purpose you suggest.
          A powerpoint presentation from 2005, detailing a laboratory experiment of mm waveform transmissions.
          A wireless LAN in a Navy ship

          mm waveform technologies have physical limitations. At the “low power” implementation you mentioned in your previous post, the range is “typically less than 10 metres”. They are also highly susceptible to atmospheric conditions, such as humidity, rain or fog, any obstructions (including foliage).

          In short, you referenced nothing that is tested/available for a deployment anything like what you are suggesting, let alone one that has actually been deployed anywhere in the World. Almost all references I could find for mm waveform wireless only talk about 100m) mm waveform tech. There is most certainly nothing even close to being available to be deployed in lieu of the NBN, and even if there ever is such tech available, it will (by necessity) be extremely high power to overcome the physical limitations of the wavelength. Not only would this mean very high EMR both at the node and the premises, but also vastly increased power usage, making it rather expensive to operate and very environmentally unfriendly compared to FTTP.

          WiGig is something different again (being an evolution of the current WiFi technology) and not designed for the sort of deployment you are advocating. It uses a very limited amount of unlicensed spectrum to provide a total maximum theoretical bandwidth of 7Gbps, still subject to contention and to interference from adjoining-base stations. It is described as “an extremely short range” technology, and the only mention of range on the alliance website is that it “exceeds 10 metres”. Another reference gave a range of “up to 80 feet (26 metres). Doesn’t sound very promising for a neighbourhood deployment to 100 premises, covering ~300 metres, through brick walls!

  21. Howie says:

    I was a bit dissapointed at the “cost” section. While it’s true that Fibre optic’s performance is without a doubt better than wireless, have we thought about the cost of rolling them out ? I still think that people roaring for the NBN are mostly techies and didn’t really take into account the financial side of things. Australia is going broke. This should be well accepted. Any financial adviser when faced with such a situation will look for avenues to save money to avoid sinking. A wireless network tower can serve hundreds of home, cheaper and faster to deploy, whereas the fibre solution requires the NBN to lay fibres to every single house. I think there should be a compromise in which regional and remote areas should be given wireless NBN and only premises in and around the CBD are given fibre optics. Just my 2 cents.

    • NBN Myths says:

      Hi Howie,

      Smaller regional and remote areas do get the NBN via either wireless or satellite. It is only towns with over 1000 premises that get the NBN via optical fibre, or 500 if they are located along the transit network.

      Wireless is really only suitable as a fixed line replacement for such small towns with low population densities. Outside these areas, even ADSL2 delivers better performance than wireless, because wireless slows down the more users are connected. There would be little point installing wireless NBN in larger towns that already have ADSL2. To assess your suggestion that a wireless tower could serve “hundreds of premises” a 4G wireless cell serving 300 premises could only deliver 0.5Mbps to each premises simultaneously. Even if you assume only 10% simultaneous usage, that’s only 5Mbps per premises. Why would you bother?

      Australia is far from “going broke”. We have one of the lowest debt:GDP and debt:revenue ratios of any country in the World, and are one of only 8 countries with a universal AAA credit rating. On top of that, the NBN is funded from user revenue, so the debt associated with it is repaid by the users anyway.

      • davidL says:

        Just a point of correction.
        The NBN co’s 4G Fixed wireless is a speed capped service with a guaranteed rate. The Radio access network is dimensioned such that the number of concurrent users does not affect the throughput of any individual user.

  22. Bauxite says:

    “A single strand of fibre-optic cable can carry 20,000 times more data than the entire radio frequency spectrum combined.”

    I don’t doubt you, but I’d love to see some kind of calculation of the data speed for the entire radio spectrum combined (assuming we lived in a world where we didn’t need tv, radio, etc, and there was just one person in the world who wanted to watch videos of cats on youtube).

    • Matt says:

      Good arguments on both sides. I would like to throw my 2 cents in.
      I have been working in the IT industry for the last 14 years and in that time wireless has never been a replacement for a direct cable installation. It has always been slower and less reliable.
      That doesn’t mean it might not catch up in the future. However when it does you can be sure that cable network will also improve.

      I don’t think you can use the argument about what the general person will use the network for. For technology that is limited no users can make it do what it fiscally can’t do there for you are limited.
      Let me give you an example of what I mean.

      If 10 years ago when everyone was using 56 k modem you said let’s try downloading a 4 gb movie or stream some video from the web it will take 6 days to do, no one can wait that long. So it is hard to relise the potential of a service that is not pshically able to provide.

      One last point I might add is that I play allot of Internet games. And for me a direct cable connection in terms of reliability and performance has always been the way to go. Sure wireless is fine for the general user downloading some Facebook or what ever but for the people who use these connections in other ways you can know the potential until the service can provide it.

      Not sure if that made much sense :) my spelling is bad cause I am on my iPhone.

        So the mug tax-payer forks over $36bill so you can play computer games, uh-huh?

          Not just for games. But, online games aren’t going away. They are getting bigger and bigger and they demand low latency connections.

          But, yeah. NBN just for online games.

  23. Wouter Wurth says:

    No country has ever suffered from good infra structure, I think the opposite is true. The so called “mug tax payers” are simply good citizens thinking about the future and strengthening the technological skills required for the future and to move with the times. Difficult to imagine no running water, no sewage system, no electricity. No free ways, no roads, no trains. Infrastructure sets the more mature countries apart from the aspiring countries. Money invested on such a wonderful internet system with its obvious benefits. The money invested finds its way into the economy and employs and feeds the population. Will enable country town to survive. The initial investment will than be payed of by the users that will all be grateful for a system that works and can be upgraded for a long time into the future. As always it takes a Labour Government to initiate such a large infrastructure programs and to get it started. I for one am not looking forward to the wreckers around the corner.

    • Tom says:

      Plenty of countries, however, have suffered from spiv politicians who promise “good infra structure” and fail to deliver it.

      • Wouter Wurth says:

        A projects such as the NBN which is so large that cannot be done by private enterprise normally starts with a vision, followed by a feasibility study, followed by a promise of implementation, backed up by funding from a willing political party and white anted by an opposition political party. If they are spiv politicians I do not know. The best sailors are usually on the land!

  25. davidL says:

    It’s worth noting that there are many myths applicable to both NBN’s being proposed. It’s far from being one sided.

  26. Bloggs says:

    Cool, Korea is upgrading their Fibre to a very high speed…. noticeably Korea is a very small country with a large population and is quite rich….. translate that to Australia with huge distance, small population and small GDP and how the hell do we pay for it? NBN Co can’t perform to deliver. You article is biased and fails to translate the issues to the unique Australian envoironment.

    • NBN Myths says:

      Our GDP is about the same as South Korea’s, although it’s true our population is much smaller and our area is much larger. Our GDP per capita is about double SK’s. Our net public debt is about 1/3 that of South Korea’s as a % of GDP, according to IMF figures. We also have a lower % of our population living below the poverty line. So, we too are “quite rich”.

      While we have huge distances, this doesn’t really matter in the context of the NBN, because the FTTP portion of the NBN is only installed in urban/suburban areas. In rural and remote areas, the NBN is wireless or satellite.

      SK is just one comparison. There are over 60 countries around the world installing FTTP to one extent or another. Because of our larger distances, FTTP is ideal for Australia because there’s no speed drop off over distance. Conversely, with FTTN (the Coalition’s policy) you need to build a cabinet every ~500m. In a country like SK, that might mean a cabinet for every 200 premises. In suburban Australia, you’ll need a cabinet for maybe every 20 premises.

      How do we afford it? Easy. The NBN is paid for from user revenue, in exactly the same way as we paid for our electricity, water and telephone networks etc. And all of those networks were installed in the same large, small population country.

      Finally, what would you suggest we do instead?

  27. jwbam says:

    DIDO is not even vaporware – it’s a SCAM outright.

    It’s designed to fool people who know lots about IT, computers and digital electronics and maybe a bit about wireless, but don’t have a background in antennas or electromagnetic wave propagation.

    It starts off by explaining the existing technology (cellular) and some of its short comings (sharing of spectrum) and shows how an alternate technology (actual MIMO and MISO) gets around that. It omits to mention that MIMO is already used by WiFi and 4G networks. It shows how 3 towers can provide 3 times the capacity (so does cellular, but they omit that) and then makes a bold unwarranted leap in asserting that they can scale this up to 1000x just by using cloud technology.

    They then confuse the reader by mentioning that DIDO can work on any frequency band (so can any other modulation and multiple-access technology) then lists the benefits of using

    a) long-wavelengths (over-the-horizon) while omitting the need for large antennas and high power, and

    b) low-power and short-wavelengths (smaller antennas and transceivers) while omitting to mention that this contradicts (a)

    and makes the reader think that it can do BOTH at the same time.

    The experiment done by Rearden was NOT done in a lab, but in a paddock where cows kept knocking the antennas over. The antennas were BIG.

      Darrell,

      Mbps and Mb/s are two different ways of writing exactly the same measurement: Megabits per second.

      Perhaps you’re confusing MB and Mb (Megabytes and Megabits), which are two different measurements.

  29. For a better and stronger OZ says:

    Thanks NBN Myths for your work on this subject.
    It makes the mud a little clearer for me the the home user with a business. It is clear you have done a huge amount of research and testing and for this I appreciate. Clearly both side of politics have not really done the same in implementing or rolling out the technology and this has caused a lot of issues.
    However, fibre, copper and/or wireless we need to fix the old and extremely expensive copper network we have used to a degree effectively for many years. But lets face facts though it is impractical and cost effective to maintain its use and the best alternative we have for now and even 50 years time is Fibre with its beneficial partner wireless. I presently use both wireless 4g and have fibre/wireless network in home which allows me and avg of 7 – 30mbps and can’t wait for the 100mbps service with NBN. As the cost to my lower productivity waiting for high graphic files is expensive. For big business and especially medical services are truly holding Australia back. Lets face it if we Australia get inline with the world we will not fall behind like other countries. The old network is run down due to Telstra and our great political system,so do we go on with a system that is extremely expensive to run to avoid paying for a system now? Then after all this we go ahead and change it which we have to at some time, which then will be much more expensive than now. In the meantime we have paid probably a huge amount more to have a far more useles system and fall behind the world, have more limitations on our lives all for a Political driven propaganda campaign to suit the pockets of politicians and the board members of large corporations.

    I could go on with this for days, but lets face up to reality, we need to replace the copper with fibre, that is it in a nut shell. Wireless is not capable and for productivity reasons we have little other options over the next 20 or maybe 30 years. You can reply with all the techno-garble and dreams from all the research in the world, but there is nothing possible now or over the next ten years that will be near as cost effective as replacing the copper with fibre. If so the USA, Uk or many other more financial vastly smaller countries than Oz would be implementing these systems and so far I haven’t seen or heard anything to prove otherwise.
    SO why are we wasting time on holding up and complicating this now critical change for Australia, I don’t know. “NBN Myths” thanks again for this unbiased forum and please get someone in Canberra to actually get some brains. The opinions of idiots like Jones and other shock jocks that only have an interest in creating conflict to build ratings to fill their own pockets need to be removed from the airwave. The NBN is a great plan as was copper telegraph lines and then phone lines. These were extremely expensive to install then, but we loved the function of being able to pick up a phone and call an ambulance. now we can do so much more and have entertainment at our fingertip with far more productivity, just compare the old dial up days.
    Please people put aside your political and technical agendas and get me and Australia NBN with 100mbps PLUS ASAP.
    We need it for today and tomorrow we need a bucket load more as we advance. Even if wireless gets close to fibre speeds in 10 -20 years, the fact is Fibre is just simply more reliable and immediately and for the next 10+ years it is simply how we must go.

    “That’s not to say wireless networks won’t continue to improve. Of course they will. But they will never approach the current or future speeds available via fibre-optic cables.”

    back i nthe 1950′s they said heart transplants could never be done.

    it is called the ostrich approach and you have it in spades. Total load of crap this item.

    • NBN Myths says:

      No Phil, it’s called physics. Wireless bandwidth isn’t limited by technology, it’s limited by the physical bandwidth of the radio frequency spectrum. It’s finite, and you cannot make more. It’s also limited by the physical properties of radio waves, for example their ability (or lack thereof) to pass through solid objects, and their range. None of these limitations can be effectively overcome with improved wireless technology.

      Of course, the bandwidth of optical fibre is limited by the size of the light spectrum. But the light spectrum is much larger, and because the light is contained within a fibre it’s not subject to the same levels of loss or interference as radio.

      This is completely different to people saying in the 1950s that “heart transplants could never be done” (if they did indeed say that). There was no scientific laws preventing them from occurring, we only lacked the knowledge and equipment to perform the procedure. For wireless to ever approach the capability of optical fibre, we would need to rewrite the laws of physics. An extremely unlikely prospect, and one which no telco in the World is betting on occurring. It’s also likely that any method to increase the size of the radio spectrum could also be applied to the visible spectrum, and therefore further increase the capability of optical fibre as well.

      Surely you must ask yourself why there isn’t a single telco on the planet proposing to replace urban fixed networks with wireless?

      • Tom says:

        Urban? Hang on there, a bit narrow, “NBN”. A fundamental tenet of NBN is to get non-urban users something closer to equity. Or have you forgotten?

        Yet one by one these Telcos are providing more mobile phone services at the expense of their fixed line services. Yes, customer convenience beats the rolled gold geek solution every day of the week.

        People in droves are installing wifi routers rather than the quicker ethernet cables in their homes. iPads, tablets etc are slower in communications than a desktop on an ethernet cable. Yet Australians are shifting to them (even in urban areas).

        It is quite clear the argument does not lock into an absolute comparison between speeds and never should have in the first place.

        Phil is correct, the geeky religious fervour towards FTTP and anti-wireless is narrow and “ostrich like”.

        • NBN Myths says:

          Tom,

          Outside urban/suburban areas, the NBN is not FTTP, it’s LTE or satellite. The point is that LTE (or any wireless) is only suitable as a fixed-line replacement in areas with a low population density. That’s why the NBN (and Telcos in other countries) only deploy it as a fixed line replacement in small towns.

          If you’d like to see what happens to mobile broadband in moderate to high population density, just attend a major event and try to upload a photo or video. Now imagine that sort of performance every day at home, because that’s what you’d get if a sizeable portion of the neighbourhood tried to change to mobile broadband at home.

          WiFi plugs into the fixed network, not the mobile network. And while its slightly slower than ethernet, it’s still faster than ADSL which means the ‘bottleneck’ is not the in-home medium. It’s the connection to the wider internet. For anyone on anything less than FTTP, there’s almost no difference in the practical speed of a computer connected via WiFi or ethernet cable. So why not use it in your home? I do unless I’m running a rendering cluster.

          If you think I’m anti-wireless, you’re mistaken. I use 3G and 4G wireless every day. I’m just saying that it is not suitable as a fixed-line replacement in urban and suburban areas. Which you’ll find is the opinion (and practise) of Telcos all around the World. Fixed and wireless networks are complementary. We need both.

      • David L says:

        I’m always amused when people talk about the physical disadvantages of wireless.
        Sure, RF is attenuated by man made and natural structures, but It shouldn’t be dismissed that the disadvantage of FTTP is that it requires an optical fibre to be installed before it can actually work.

        The wonder of wireless is that it doesn’t actually need a dedicated transmission line, and yet this is somehow (mis) represented as a disadvantage.

        • NBN Myths says:

          There are pros and cons to every system.

          The pros of wireless are mobility and convenience. The cons are cost and capacity.

  31. TheFatController says:

    So naïve.
    As wired Ethernet ports on laptops are being phased out, you think cable is the future. It is ridiculous. Everyone is connecting wirelessly even in the home, and more likely people ant the internet when not at home. What good is fibre for the wireless future?
    Yes a fibre optic infrastructure is needed for the backbone of an upgradable wireless system.
    Wireless technology is moving in leaps and bounds. Home WiFi is already past gigabit speeds with 802.11ac. By the time the NBN rollout would be complete, the mobile wireless technology will be fast enough to stream HD video. How much faster do you need in your home?
    Fibre now would be nice, but the rollout is very slow, and the cost of fibre to every home is unnecessary.

    • NBN Myths says:

      Naive indeed, Mr Fat Controller.

      The existence or not of ethernet ports on laptops is not even vaguely related to the delivery system of broadband to premises. That said, specific ethernet ports are not required anymore, because laptops have other methods for wired connections if required (such as Thunderbolt and/or USB-ethernet adaptors).

      Improvement to WiFi is an argument for fast fixed networks, not against them, because WiFi is a short-range wireless system that plugs into the fixed line network at your home or business. 802.11ac (which uses the 5GHz band) has an effective range of only 50m with walls in the way, meaning it cannot effectively be used to deliver from a node into a premises. Additionally, to achieve gigabit speeds, there is only sufficient bandwidth for 5 160MHz channels (ie 5 simultaneous users within range of the router). Again, making it totally unsuitable for wide-area service provision.

      For wide area wireless, you would use something like 4G/LTE, not WiFi. And all the drawbacks listed on this page apply to it. Like all wireless systems, it is incapable of delivering high bandwidth to a large number of users. It’s got nothing to do with the technology, and everything to do with the physics of radio waves.

      Mobile wireless can already deliver a single HD video stream. Several simultaneous streams, in fact. 4G/LTE can deliver 150Mbps per cell, and a 1080p stream uses about 15Mbps. But that 150Mbps cell actually serves several thousand customers. To serve 1,000 simultaneous HD stream connections, mobile wireless would need to increase its capability by 10,000% (to 15Gbps), assuming zero signal loss. With the limited amount of radio spectrum available, such an increase is highly improbable within our lifetimes, if ever. And what would we do when 4k and 8k TV reaches critical mass, with a single 8k3D stream requiring ~300Mbps?

      And that, Mr Fat Controller, is one of the reasons why not a single Telco on the planet is proposing to replace metro fixed networks with wireless. Wireless is complementary to fixed networks, not a replacement for them. We need both, not one or the other.

      • stomfi says:

        I agree. One has only to look at the ISO communications model and the proposed architecture of the global network set out in the ’80s when all the basic machines and protocols had been invented to see how the whole she-bang fits together.
        . The network must be robust. Not affected by traffic volumes or within reason, acts of nature or people, or distance.
        . The human interface must be portable and natural. This means conversational voice and AV output at a minimum.
        .Information farms store and manipulate data.
        .Peer level interconnected work nodes perform user generated activities and store user data in a network raid scheme. The nodes form a vast interconnected network with each other that is difficult to disable. Nodes have a private network and OS as do all levels.

        Nodes aren’t big. A home unit must be able to serve everyone if the network fails. When the network is up, users interface with a nationwide supercomputer.

        This final level is due any day Have to wait for people to accept cloud storage. The point is that work nodes generally use fixed line and the user interface is wireless to the work node network.

  32. Halcyon Ford says:

    As early as 1994 Australia’s CSIRO reviewed worldwide research on the effects of radio and microwave frequencies on the human body. The report of this review was authored by Dr Stan Branett from CSIRO’s Radiophysics Division. The 150 page CSIRO report listed many well documented adverse biological effects from exposure levels well below the current safety limits. The report stressed the need to investigate the biological effects to ensure public safety in a rapidly developing wireless technology market.
    Although early reports such as CSIRO’s have highlighted the potential risks and the high level of what is unknown about radiofrequencies on the human body, untested wireless technologies continued to be developed and introduced into all areas of our daily lives.

    • Tom Russell says:

      These minor inconveniences are nothing compared with the radiation frequencies and quantities thereof, we receive from the Sun. The immediacy of mobile connections augmented by a robust high speed National network will change our behaviour more than any concentrated burst of radiation on random targets.

      • Halcyon Ford says:

        So EMR from the Sun is the same as the EMR from man-made devices?

        Wrong. Fundamentally and hopelessly wrong. The exposure standards for UV-B and man-made EMR are both set at 200 micro watts/ cm2.

        Both burn at that level. But man-made EMR is pulsed. Near an EMR tower, exposure is both DAY & NIGHT exposure. The Sun exposure is considerably less and clothing, being inside, sun screen and a hat can protect you and limit this exposure well below 8hrs.

        You cannot readily reduce your exposure from manmade sources of EMR.

        As you know, UV-B does not have to burn you to cause damage to skin cells and the collagen and if current science is accurate, the same applies to EMR from towers and wifi.

        What IF humans mistake man made EMR for sunlight and the body cannot repair at night time because the Pineal Gland cannot produce the required levels of Melantonin?

        Yes, this is the current explanation for a variety of major health concerns around low-level, long-term EMR exposure from towers, wifi, cordless phones and cell phones.

        • David L says:

          What about the rest of the sun’s energy?

          The energy from the sun is actually 1000W/m2 at the sun’s zenith. This is 500 times greater than the Arpansa PUL limit for RF radiated field strength. Both sources are E-M.

          • Halcyon Ford says:

            Again, at the risk of repeating myself, sunlight does cause damage as we well know. By definition, sunlight occurs during the day.

            The pineal gland is light sensitive and regulates the immune system , hormonal balances and anti-oxidant release when the sunlight stops.

            Man made, pulsed magnetic flux electromagnetic radiation may be sufficiently similar to ‘sunlight’ that the human body mistakes it for being sunlight – thus impairing the bodies ability to operate cellular repair functions at night time when exposed to man made radiation 24x7x365.

      • Halcyon Ford says:

        Here are new Health Warnings from ARPANSA that you never heard of:

        http://www.perthnow.com.au/technology/parents-urged-to-limit-childrens-use-of-mobiles-cordless-phone-under-new-health-warnings/story-fn7bsj10-1226589473040

        But ARPANSA – the Standard authority that issued this ‘secret’ warning also states on it’s website “There is an extensive world wide research program into the possible health effects of low level RF exposure. ARPANSA will review the limits of the Standard if evidence does emerge of a causal link between low level RF exposure and adverse health effects in humans.

        The Standard incorporates a “precautionary approach” which requires owners of RF sources to minimise unnecessary exposure of the public to RF fields. Australian regulators and codes of practice will decide how this statement is applied. ”

        So man-made EMR has NOT been proven to be safe and ARPANSA leaves the Industry to decide how to implement a Precautionary Approach – which allowed NBN Co to try to install a Tower 50 meters from someones living room (MacLeans Ridges, NSW) – and 2,400 more towers across the country wherever they want too.

        Something is very wrong with this ‘experiment’ on the Australian Public.

        • David L says:

          Typically, the field strength from a mobile phone tower @ 50m is equivalent to that of a TV / FM broadcasting tower @ 5000m.

          This so called “experiment” has therefore been in operation for about 50 years.

          If you’re worried about the environmental RF levels, perhaps you should move into a remote rural area.

  33. Ben Miles says:

    Great article. really great. If its ok with you I’d like to share on my business Facebook page and my website?

    I’m sure I will be coming back to this article as a reference for years to come since that’s how long it’s likely to take to get FTTP, or FTTN for that matter, on Phillip Island.

  34. Time and again I see articles espousing the virtues of the NBN but what I don’t get when I see you speed test showing an optus cable getting 9Mpbs then I do a speed test on Optus cable and get 98Mbps I got to wonder if someone is trying to misrepresent good ol’ copper. I mean if it was that bad it wouldn’t need to be misrepresented? would it?

    • NBN Myths says:

      A few things there David. First Optus cable isn’t exactly “copper”. It’s hybrid fibre-coaxial cable. Only available to about 20% of the population, since the rollout ended about 15 years ago.

      HFC is a shared medium, which means the speed available varies based on how many users are connected to the network in an area, and how active they are. That’s why HFC speeds vary widely during the day, and why some users get high speeds while others get very low speeds. Optus have recently upgraded parts of their network to a new standard, which allows higher speeds. But their website still says only that 80% of users can get >8Mbps.

      HFC also has extremely slow upload speeds. Check for yourself, and compare your upload speed to the NBN’s ~40Mbps on the 100Mbps DL plan.

  35. Tom says:

    At one extreme is urban where FTTH is viable and wireless has overlap and latency disadvantages.

    However at the other extreme is the remote areas such as Whitecliffs where a person would be insane to advocate FTTH.

    In between are the grey areas where judgement needs to prevail on the extent of FTTH as opposed to wireless / satellite configurations.

    It beats me why some people choose view this simple argument with such religious fervour.

  36. Ben Miles says:

    I think calling someone insane for advocating a cable being laid in place of a wireless signal is a bit extreme. They called people nuts when they originally laid the comes pipes in the Atlantic ocean but it worked; and now we have cable a ros sea beds across the planet.

    That said, I’m not familiar with the topography of White Cliffs but I presume from your comment that it’s pretty mental. but that doesn’t mean cables couldn’t be used, it might just be a very tough operation. Nothing is impossible, just highly improbable or impractical.

    As the original article states fixed wireless nbn is ludicrous both for congestion, distance and lack of speed but I’d suspect that many would adopt it if that’s their only option since it will be ‘better than nothing’.
