Australian Researcher Boosts ADSL Speeds

Posted by Zonk on Mon Nov 05, 2007 04:26 AM
from the pouring-go-faster-juice-down-the-tubes dept.
sea_stuart writes "Like your ADSL connection to go 100 times faster? Despite the grim state of Australian mathematics and science, there is still exciting original work being done Down Under. John Papandriopoulos, a Research Fellow with the ARC Special Research Centre for Ultra-Broadband Information Networks (CUBIN) has developed a method to reduce crosstalk interference in ADSL technologies to bring speeds up the theoretical maxima possible. With an Australian Federal election due in a few weeks, and both parties promising improved broadband speeds and access, this is a welcome development, hopefully enabling higher speeds without huge expenses."

      Its partly because a Universal Service Obligation is built into our telecommunications laws. Companies which supply loss making services to remote areas get a subsidy from companies which do not. It may not be a driver in the current debate but it is certainly a symptom.

      Another factor is that remote areas are currently being hit bad by a drought. Hand wringing over communication is one way for the Government to be seen to be helping people where they can't really do anything about water.

      And to top it off, we actually have a very bad problem with rural infrastructure. We have 1/10th the population of the US, and slightly less land area to service. The cost of improving service in remote areas is a political hot potato. The party currently in power is a coalition of the National party which traditionally supports country voters and the more broad based Liberal party. By making broadband an issue the Government is trying to tell the country voters that the opposition Labour party doesn't have an interest in supporting them.

      • Its partly because a Universal Service Obligation is built into our telecommunications laws. Companies which supply loss making services to remote areas get a subsidy from companies which do not.

        A law like that in the United States wouldn't have made it past the Reagan administration. American law is written by telecom lobbyists and is designed to create and sustain fake scarcity of telecommunications services.

      Don't worry, broadband really isn't an issue in the election campaign down here in Oz. In fact, we're have a very US-style personality-based campaign, with precious little policy detail in any area.

      And for what it's worth, if the howard turd gets re-elected once more you're welcome to move here and take my place. Give him another three years and every last one of the old Australian values will have been replaced by fear, xenophobia and selfishness.

        • We have a cable modem service here too. There is one provider, it peaks around 7M and is capped at 20 gigs, throttled down to 64k (yes, dialup speed) once the cap is reached. That cost $60AUD/month. They recently expanded the plans (yes, there was one provider with one plan for quite a while) which are just as pathetic. Luckily the competition regulators opened up the exchanges and the smaller players have been installing adsl2+(theoretical 24M, realistic 8-12M) with decent plans for a while now, all this e

      Maybe it's because I'm Swedish and not an expert on English grammar, but doesn't your fine language use "is" when the subject is singular? I.e, "our population is literate"?
      • Well, Brits and people who speak British English have yet to figure out the concept of "collective nouns" and their place in subject/verb agreement. They will argue that since "a population" necessarily consists of multiple individuals, it is a plural noun and requires the verb "are". This is incorrect -- a population is a single, collective entity, and requires the verb "is". Examples include "The band are playing" or "Microsoft are releasing an update". However, they will fight and argue this until th

    If his technique can make ADSL work at greater distances from the exchange then he might be on to something. I know people who live in non-urban parts of Australia who are just on the limit of distance to the exchange for ADSL to work.

    Doubling that distance could increase the number of homes covered by a factor of four.

    There's a company in Sweden called UpZide Labs (http://www.upzide.com/ [upzide.com]) that's been working on a technology called VDSL (Vectored DSL) for a few years. This also promises speeds of 100Mb/s using normal copper connections in use right now with normal ADSL.

      First: VDSL is already in active deployment e.g. in Germany (offered in speeds of 25/5 and 50/10 mbit here). Second: VDSL does NOT stand for "Vectored DSL" but for "Very High Speed DSL".
    • Some time back, a company called Genesis Europe were going to rollout a VDSL network, what ever became of it I wonder. As for VDSL, this article has something interesting to say about it.

      "Mr. Walker .. claims VMSK achieves spectral efficiencies of 90 bits/sec/Hz or more .. These claims are in direct violation of the mathematical principles of digital communications discovered by Harry Nyquist (1928), Claude Shannon (1948), and others"

    "Our strategy is to sell higher upload speeds only to business clients"
  • In the UK as ADSL gets faster the traffic allocations seem to get even meaner. The prices of ADSL connections remain static, even falling, yet the speed of the connections increase. This is obviously unsustainable and this is why people are complaining that they have an 8MB connection yet only get about 4-6MB download speeds.

    There's already 50:1 contention, if the ISPs and BT don't increase the speed of their pipes and add more pipes then the extra speeds accounts for nothing.
