Thanks for that explanation - so we messed up selecting Alcatel-Lucent but we didn't have many options.

I understand that wireless has a saturation issue, but I run both a wireless modem and cable internet connections, and I'm surprised at just how fast the wireless is. Most operators in rural areas will be quite happy to get a good wireless connection. For a large user it might pose problems though.
The problem with wireless isn't so much the speed as it is the amount of users it can handle at that speed. Currently it is good cause most of a suburb uses fixed line internet, if all of those people tried to use the wireless at the same time it would die horribly.

Wireless is an important technology that should exist to compliment fiber optic, not replace it.

Tough decisions. Vote Abbott and nail some lefties to the wall and satisfy some blood lust, sack some public servants and put downward pressure on house prices, or NBN.
Easy decision moops.
Common sense is a curse - those who have it need to suffer dealing with those who don't have it.

Tornado light beams could turbocharge bandwidth

Vanessa Desloires

A new method of transmitting multiple light beams in a twisted-motion down fibre optic cables could dramatically boost internet bandwidth, as the current system struggles under the growing demands of internet users.

Developed in collaboration with Boston University, the University of Southern California, Danish optical fibre company OFS-Fitel and Tel Aviv University, the method involves sending doughnut-shaped laser beams, or optical angular momentum (OAM) beams, which twist the light down the cable like a tornado, allowing cables to transmit significantly more data than the current cables.

Boston University’s engineering professor Siddharth Ramachandran said that OAM beams were previously thought to be unstable in fibres.

“Our discovery, of design classes in which they are stable, has profound implications for a variety of scientific and technological fields that have exploited the unique properties of OAM-carrying light, including the use of such beams for enhancing data capacity in fibres," he said.

The current fibre optic cable technology, established in the 1990s, is rapidly reaching its physical limits due to the growing rate of internet-enabled smart devices and on-demand video streaming.

The researchers tested the method through a one-kilometre fibre, and discovered a transmission capacity of 1.6 terabits per second, or the equivalent of eight Blu-ray DVDs per second.

NBN costs set to soar past $60bn

by: Annabel Hepworth, National business correspondent
July 24, 2013 12:00AM

CONSTRUCTION contractors on the National Broadband Network are pushing to be paid up to 40 per cent more to do further work, fuelling fears of a cost blowout on Labor's flagship infrastructure project.

The Australian has been told that industry suppliers are looking for increases in the value of contracts of between 20 per cent and 40 per cent for further work and that high-level evaluations are circulating suggesting that the ultimate cost of the project could spiral out to between $60 billion and $70bn.

A slew of NBN Co’s current construction contracts are due to expire between this year and 2016 and will have to be renewed; NBN Co is also expected to take tenders for delivering fibre, fibre links and new developments this year. Some of NBN Co’s main contractors appear to have hit financial strife and some of their sub-contractors have downed tools in Victoria and Tasmania, claiming they are not being paid enough. “There’s a huge probability this thing will go completely through the ceiling,” said a senior industry source.

“You’ve got a situation where a 30 per cent increase would be in most cases probably a minimum. And they haven’t attacked any of the difficult work yet, as in downtown Melbourne and Sydney, where you have older apartment blocks.”

NBN Co spokesman Andrew Sholl yesterday denied suggestions of a cost blowout. “The NBN remains on course to be delivered on time, and on budget,” Mr Sholl said.

“Our prerogative in negotiating all our contracts is to deliver value for money for taxpayers.

If you want to be a skeptic you should first understand the architecture of the Internet.

Admittedly NBN Co and the government have been useless at promoting it properly.

Here some facts NBN skeptics must consider.

1. Copper is at end of life

2. NBN will not be a ‘white elephant’ as there are solutions and apps to run on it now and more being developed at NICTA and CSIRO.

3. The Web is about 50% heavier now than five years due to Java coding and plugins and APIs, not video.

4. NBN is only a layer 2 network – what RSPs do with it and QoS is important.

5. Productivity gains are more difficult to find have been with comms networks though Melbourne Business school is investigating this now.

6. Business needs it now because of latency and the biggest use of the internet amongst business is video conferencing and data back ups. Those are facts.

Porky pies fly thick and fast as pollies log in for broadband boost : VIDEO

Labor MPs have been running highly contestable and in some cases ''deliberately misleading'' advertisements for the national broadband network, experts say.

The Labor advertisements range from blatant falsehoods (saying the Coalition's NBN will cost $5000, while Labor's will be ''free'') to misleading comparisons (comparing the highest speeds possible under Labor's NBN with the minimum guaranteed under the Coalition's) and assertions (that the Coalition's NBN would not support high definition video conferencing).

Fairfax Media has reviewed Labor's NBN advertisements from around the country and found questionable claims in many of them. The Coalition has been running fewer NBN advertisements than Labor, but has made at least one highly contestable claim - after doing its own calculations, the Coalition said Labor's NBN would cost about $94 billion – adding some $50 billion to NBN Co's official figures.

The most contentious of Labor's NBN claims was by Families Minister Jenny Macklin, who said the Coalition's NBN would not support high definition video conferencing for e-health and education.

"Some of the claims being made here are highly contestable and seemingly deliberately misleading," said Tony Brown, a senior analyst at Informa Telecoms and Media. Other independent telecommunications experts, Paul Budde and David Kennedy, contradicted one or more of the claims in Labor's NBN advertising.

How to dodge shock NBN costs

Posted on Tuesday, July 30 2013 at 2:38 PM

The ongoing rollout of the National Broadband Network (NBN) will see households connected to superfast internet, but unit owners can’t just sit back and hope for the best when it comes to work in their complex.

Body corporate committees should be acting now to avoid future headaches as a result of installation works, according to Archers Body Corporate Management.

The company’s managing director Colin Archer says some strata title complexes could be left with permanent, unsightly cable lines fixed to building exteriors.

In addition, a body corporate would cop expensive call-out fees if a NBN installer had to come back to the complex for any reason.

Unit owners, particularly those in older buildings, smaller complexes or those without an onsite manager, should get together to decide how the cable systems will run, address any potential installation issues and ensure NBN contractors have clear, unobstructed access.

“Bodies corporate should nominate a committee member, owner or onsite manager to be the onsite contact for installation,” Archer says. “Once a liaison has been established, the nominated person needs to register their name and contact details at the NBN website.
They’ll be notified prior to NBN installation in their area, at which point the contact can discuss the installation plan and any building requirements or issues.”

Owners should also be mindful of any special requirements at their complex. The committee should first discuss how the cabling is going to be installed, if there are any access issues to the property, or whether there’s asbestos in the building.

“Owners of older buildings in particular need to discuss where the NBN cables will actually run. Newer buildings tend to have established conduits, whereas in older buildings the utility infrastructure is often set in the slab, so in the absence of a prepared solution you could end up with cables running all over the exterior of your building, which looks unsightly.”

If there’s a chance the building might be at risk of this, owners should engage a professional carpenter or builder in advance of installation to prepare a solution, which might include the creation of a pillar or duct for the cables to run through, he says.

Failure to be prepared for the NBN could see some buildings face financial, aesthetic and logistical chaos, but with a little preparation he believes complexes can guarantee a smooth transition that will ultimately allow residents faster, more reliable broadband access.

Speed check: what NBN speed promises really mean

August 2, 2013 - 1:40PM
Lucy Battersby

When Brunswick resident Katia Zanutta hooked her computer up to the national broadband network for the first time she understandably went straight to a speed testing website to see how fast it was. After all, speed is the NBN’s main attraction for consumers.

Used to a sluggish and intermittently slow ADSL connection, she was delighted to get a download result of nearly 47 megabits per second (Mbps), upload speeds of more than 18 Mbps and an extremely low latency reading.

But the next night, using the same testing site, Ms Zanutta got a result of 31.4 Mbps.

Fixed broadband consumers may not realise how difficult it can be to get an accurate speed reading, or how many different factors affect broadband speeds.

Speeds depend on a users’ equipment, the quality of the connection between the house and the exchange, the capacity of backhaul at the nearest exchange, traffic at the testing sites’ server, and capacity on international cables.

Internet carriers are quick to point out all the places outside their control where speeds can slow down, while testing sites stand by the accuracy of their results.

Now the introduction of the NBN has focused attention on download and upload speeds like never before.

When Ms Zanutta tried testing her speed on different sites, the results varied drastically – on speedtest.net she got an average of 46.3 Mpbs, but on CNet’s speed test she got an average of 36.8 Mbps. A third site, ozspeedtest, returned an average of 45.9 Mbps.

She had signed up an Internode plan described as 50 Mbps, so uses that figure as a benchmark.

‘‘Realistically I know that I am not going to get that many [50 megabits per second] because life is full of disappointments,’’ Ms Zanutta said.

Arrogant Kevin Rudd hides NBN truth

KEVIN MORGAN
From: The Australian
August 14, 2013 12:00AM


KEVIN Rudd claims there is a conspiracy surrounding the NBN. He may be right. But it is not a conspiracy in which Rupert Murdoch seeks to bring down the Labor government to sabotage the NBN. It is a conspiracy to hide from the voters, until after the election, just how bad are the finances of the NBN. And the dire straits that the NBN is in can be sheeted back to the deals done by one man: the Prime Minister.

Rudd sketched out his grand vision for a Fibre To The Home network on April 7, 2009. The project was launched with a 1000-word press statement. There was no policy paper or supporting financial analysis because Rudd, who now demands the Coalition take its policies to Treasury and Finance, asked neither department for costings. And despite the fact that the first tranche of funding promised by Rudd was held in the Building Australia Fund and by legislation could only be disbursed following a cost benefit analysis, none was done. Instead Rudd plucked figures out of the air.

The initial headline $43 billion cost was not sourced nor was there any support for the extravagant claims that the project would generate an average of 25,000 jobs a year. Rudd also claimed it would be 49 per cent private sector funded although there was no indication the private sector would come to such a hare-brained party. On average over its first four years the NBN has supported 10 per cent of the jobs Rudd claimed and the revised $37bn cost has fallen fully on the government plus a further $20bn in taxpayer-guaranteed payments to Telstra.

Rudd's largesse to Telstra was extraordinary but was willingly paid as he sought a deal in the dying days of his first stint as PM. Though Rudd had conceived the all-fibre network as punishment for Telstra, who he blamed for the collapse of the first broadband policy, the truth was Telstra had to be brought on board despite his disdain for the company.

The initial policy offered $4.7bn through a tender towards an upgrade of the Telstra-owned copper network with Fibre To The Node technology. In reality Rudd knew only Telstra could deploy FTTN and in opposition had offered Telstra the money if it agreed to full structural separation, that is being split into wholesale and retail companies, not the ersatz separation inherent in the current policy.

It was an offer the then board couldn't accept and Telstra effectively disqualified itself from the tender in late 2008, leaving the government with nowhere to go. Rudd's public answer was to cut Telstra loose with the government building its own network . But given Telstra owned the exchange space, thousands of kilometres of existing fibre and the ducts NBN Co would need and most importantly held eight million customers, it was an empty threat. Indeed even before the all fibre NBN was announced the government knew it had to coerce Telstra into co-operating. The coercion was finally made public in September 2009 when Telstra was told it wouldn't get new wireless spectrum unless it got on board the NBN.

Despite the threats Telstra opened negotiations with NBN Co. in the second half of 2009 on infrastructure leasing and payments for migrating its customers to fibre. But by June 2010 Telstra still found itself some $4-5 billion short in cash on the deal it wanted for shareholders.
