VDSL2 Broadband Technology looking likely for NBN

With some Telcos already marketing VDSL2 roll outs, it’s only a matter of time until we witness the emergence of VDSL2 plans, VDSL2 speeds and further VDSL2 providers offering respective services. Australia’s two leading Telecommunication Operators, Optus and Telstra, are also conducting their own research and tests on prospective Broadband technologies such as VDSL2 (very fast digital subscriber line) and BPL (Broadband over Power Lines), the latter being considered as inappropriate at this point in time.


VDSL2 on the other hand is an upgradable DSL transmission technology which has superseded ADSL2+ and one that can also make use of the current copper line infrastructure. Visiting Ericsson telecommunication executive ‘Martin Mellor’ suggests that there’s alot to like about VDSL2 as new technologies will be able to take advantage of the existing copper lines and states that Ericsson’s latest dynamic spectrum management technology could theoretically increase maximum VDSL2+ speeds to 250 megabits (250Mbps) when it becomes available in two or three years time.


It’s becoming more and more likely from all the relevant information surfacing on VDSL2 that this type of Broadband technology will in fact become the preferred technology for delivering Broadband Internet over the new proposed national network. I would be very surprised if ISP’s that I previously mentioned were not particpating in VDSL2 tests and that this type of technology be overlooked. The question now is, not about which type of Broadband technology will be used such as FTTN, FTTH, WiMAX or VDSL2, it’s who will win the NBN bid and manage the new national broadband network.


“We think VDSL2 [transmission technology] is a great step forward from ADSL2+ but we don’t think that’s the end of the life for copper,” said Mr Mellor, who visited Australia last week. “There’s too much copper buried in the ground, and operators want to make that sweat, and there’s always new technologies that are looking to take advantage of that.”

State-of-the-Art Broadband coming

Direct Brain Surgery, conduct climate change experiements and interpret human genome in real time with precise definition through state-of-the art broadband. This could be the not so distant future according to a recent article that appeared on AustralianIT.com.au.


The cutting edge technology, founded by Phil Scanlan, is 250 times faster than a standard Broadband connection and offers ultra high definition resolution that could allow an emergency surgical operation that is conducted by a surgeon on one side of the world who operates a robot to perform the sugery on the other. The mind boggles to fathom the potentials that this kind of techonology could offer. I imagine that only time will tell to see if this new technology is ‘the real thing’ and kicks off. The Rudd Government seems to think it might, and has vowed to test the ultra high res Broadband technology in Australian Institutions and Households.


Communications Minister Stephen Conroy said the ultimate aim was “to deliver this sort of technology to everybody’s home”.

“A surgeon in Australia could direct an emergency surgical intervention by operating a robot in Antarctica; scientists in Australia and Japan could share research tools or operate an underwater robot exploring the Great Barrier Reef.”

Pipe Networks to announce Cable Link go ahead

Pipe Networks has temporarily ceased trading on shares as an announcement on the go ahead of a Fibre Cable Link to Guam is expected to be made shortly.


‘Project Runway’, which will witness a submarine cable run from Sydney to Guam, has been earmarked to provide more competition to the likes of Telstra and Optus and break the current duopoly of cable links that connect International data transmissions to Australia. Speculation on the completion of Project Runway suggests that customers may start connecting to the new cable link as early as Q1 2009.


“Pipe Networks announced in December that it would shortly have enough customers signed to go ahead with the proposed PPC-1 (Pip Pacific Cable) 1) project, which it says will give Telstra and Optus a much-needed competition for international data traffic.”

Broadband Over Powerlines in Labor and Coalition sights

Speculation over the potentiality of Broadband Over Powerlines (BPL) to be used as a mainstream Technology for  Broadband Internet Access continues to mount with both Labor and the Coalition monitoring BPL developments. Interference issues appears to be the major hurdle facing BPL as some recent trials in NSW and TAS have suggested.


Broadband is a highly contested issue being debated during the lead up to the Federal Election this weekend and will no doubt witness both parties emphasizing their Broadband blueprints for Australia. BPL could be a very viable Broadband alternative for either party as the majority of infrastructure is already in place thus making a network using BPL Technology cost effective and almost ready to immediately implement.


Communications Minister Helen Coonan told ZDNet Australia that her office is monitoring developments around new broadband technologies including BPL. My department has kept an eye on it,” she said. “[Trials of the technology] suggested it could be a way of delivering broadband effectively into the home.” “It’s very interesting. My department has a standing brief to be kept abreast of all developments,” she added.


Labor communications spokesperson Stephen Conroy told ZDNet Australia that he has seen broadband over powerline technology used in Tasmania. “We’ve got some good working models,” he added.

Mixed feelings on Oz Broadband Ranking

Australia has risen four places in Broadband world rankings which currently witnesses our position as 12th overall. That’s the good news. However, the latest OECD figures show that Australia has also started dragging the chain again and fallen behind other advanced countries due to the unresolved new FTTH Broadband Network status which the government has procrastinated with for quite sometime now.


Senator Coonan is bound to jump up and down about the elevated rankings position (whoopee do), but the real issues for Australians regards our future! The current progress Coonan and the Federal Government have made with the FTTH network development (or should I say lack of) overshadows any positives made from a higher world ranking. It’s not the jump to 12th place from 16th that we should be focused upon, it’s this lack of vision and progress (rated zero by the OECD) which places Australia way behind the likes of Japan and Korea. It’s this statistic that should be of major concern. Let’s get real here, we’re still very far from where we need to position ourselves on a ‘broadband level’ for this country to really power ahead as a prosperous nation and a potential world leader in technology.


Australia’s increased broadband ranking was the good news. The bad was that, with FTTH presently stalled, we are falling even further behind the most advanced nations.


Fibre connections account for 36 percent of all Japanese broadband subscriptions and 31 percent in Korea.” The figure in Australia was so low as to be rated zero!

BPL Technology – Broadband over Power Lines

Australia’s ongoing conjecture over a new Broadband network and what type of technology to use continues with discussion and further research into Broadband over Power Lines (or BPL). With potential bandwidth that can deliver speeds up to 200Mbps, it’s no wonder that many Telcos and Utility companies are running studies and tests to scrutinize the feasibility of BPL.  Check out the following articles to obtain a deeper insight into Broadband over Power Line technology and the research that’s currently being conducted here in Australia.


PCWorld.idg.com.au BPL Article
Chapman said the response from over 300 participating households in the Queanbeyan and Jerrabomberra region has been very positive and there have also been many requests that could not be tackled as they were just outside the pilot-designed geographic area.


Other BPL trials in Australia include those by Victoria’s SP AusNet, and Tasmania’s Aurora Energy. The technology is also gathering steam in the enterprise market where Brisbane’s Treasury Casino is using it in a heritage-listed building, where they were prohibited from installing new network cabling.


ZDNet.com.au BPL Article
John Norton, executive general manager for public network solutions at NEC Australia, said the company is already in talks with some carriers over deploying BPL to provide “last mile broadband” access, but declined to name the carriers involved.

Pipe Networks submarine Cable link to Guam ‘anchored’

Pipe Networks (Australia’s largest Internet Exchange) appears to be somewhat on track for a proposed submarine Cable link to Guam (U.S.), although progress has been subdued. Negotiations are still currently underway with many International parties in order to bring project ‘Runway’ into reality however the process might be significantly more complicated than first thought. Pipe’s quest to break the current duopoly on Internet Cable linkages in and out of Australia would be a welcome relief to Australian Internet subscribers. If the project was to go ahead, a third Cable link could witness data prices being reduced substantially by Q1 2009.


The company says it “continues to be actively engaged in negotiations…of contracts with domestic and international parties” and that until all such agreements are finalized it will not proceed with the project


Pipe announced in August that if Roject Runway were to go ahead, Tyco Telecommunications would build ad lay the cable system and had committed to a ready for service date of end of Q4 2008.

100Mbit VDSL Broadband Internet Speeds in 3 to 4 years?

It appears that ‘interference’ is the underlying contributor which impairs Broadband speeds using DSL technologies. Although this type of complication has been cleaned up within ADSL and ADSL2+ technologies, interference is still dominant.


In a follow up to a recent article on Broadband Guide, further information has been produced supporting a research by Dr John Papandriopoulos that states DSL Broadband speeds can potentially break the 100Mbit barrier using a variation of DSL technology referred to as VDSL. Depending on further research and development, it could be likely that we may witness the new VDSL technology hit the scene over the next 3 to 4 years.


From a consumer’s point of view, the news gets better as aside from network upgrades, it appears that firmware upgrades for you’re current modem/routers or relatively inexpensive new modem/routers may be all thats required to use the new technology. VDSL Broadband is certainly a topic that we’ll be keeping a watchful eye upon in the future, especially if 100Mbps+ Broadband speeds can be produced.

“Typical broadband in Australia is around 1.5MB/sec for ADSL1 and anywhere up to 24MB/sec for ADSL2+ connections. We’re looking at increasing those rates up to about 100mbs per second by managing the interference between the lines” he said.

What Dr John’s breakthrough does is reduce interference on copper telephone lines to the extent that you can run VDSL lines on them. “What we’re doing with newer versions of DSL such as VDSL and VDSL2 is employing technology to widen the broadband further, the trouble with doing that is you really need to manage the interference, which is what the research has focused on” Dr John said.

Try 250Mbps VDSL Broadband Speed on for size

If you think 12, 30 or even 100Mbps is a fast speed for Broadband? Then how about 250 megabits per second! Thats the calculation set by a Melbourne PhD student who claims that speeds at this limit are reachable using telephone lines and DSL Broadband.


Dr John Papandriopoulos won a Melbourne University academic major prize (Chancellor’s Prize for Excellence in the PhD) for a mathematic Broadband theory that suggests speeds of 250Mbits are attainable. Dr John has also applied for patent rights in the U.S. and Australia. Maybe the Federal Government should award this clever fellow a $4Billion dollar grant to develop a high speed Broadband Network?

A MELBOURNE PhD student has developed technology to make broadband internet up to 200 times faster without having to install expensive fibre optic cables.

Dr Papandriopoulos’ research, which took a year to complete, uses mathematic modelling to reduce the interference that slows down downloading.

Fibre to the Planet

Australians are certainly behind the eight ball when it comes to Broadband Technology (as we all should know by now). While the Federal Government is bungling around in la la land over a new national high speed Broadband Network as the Federal Election looms, other regions of the planet such as Asia are far more advanced than Australia using robust Fibre to the Home Technology (that’s since early 2000 as well).


Although not entirely wide spread yet, other regions such as Europe and more so Scandinavia have embraced the technology and implemented Fibre to the Home Networks. It’s easy to see that the core of Australia’s future depends on a national high speed Broadband network, so why is it that decisions and development on Broadband infrastructure in our country are taking so long and being left on the backburner?


21.2 percent of homes in Hong Kong were found to be wired with FTTH, followed by South Korea at 19.6 percent and Japan at 16.3 percent.


In Japan, FTTH often provides a 100Mbps connection for less money than Australians pay for a connection one-tenth as fast.


Take-up in Europe varies from country to country, although the most significant movement to date have taken place in the Scandinavian countries and, latterly, France and the Netherlands.


Current estimates put the number of subscribers across the continent at around one million, with Sweden leading the way with some 27 percent of subscribers.

Much of the debate around fibre in Australia remains around fibre to the node, with both the Coalition and Labor planning to authorise rollouts in the near future — should they be elected.


Labor’s communications spokesperson Stephen Conroy has previously lent his support to a FTTH rollout although the costs involved in such a move remain prohibitive, according to the Opposition senator.
