Its not easy being green--Dr. Papandriopoulos has come up with technology which promises to revolutionize the internet.  (Source: The Sydney Morning Herald)
Australian researcher develops tech to raise internet speed x100, which should hit the market in 2 to 3 years.

It’s not easy being a young super-genius who just developed an algorithm to reduce interference in ADSL lines, potentially raising broadband connection speeds by a hundredfold. It’s not so easy, being internationally acclaimed and having fame and fortune knocking on your door.

Okay, so maybe life is going pretty good for 29-year-old University of Melbourne research fellow Dr. John Papandriopoulos -- but it’s not like he didn't earn it.

Dr. Papandriopoulos's PhD thesis is comprised with methods and techniques to use mathematic algorithms to reduce interference in DSL lines. This research is grabbing international attention due to the promise it holds; ADSL connections implementing the algorithm can go from approximately 1-10 Mbps to a blazing 100 Mbps or above.

Such an increase would revolutionize the internet industry worldwide. Dr. Papandriopoulos has two patents pending on his research, which will likely bring him some future wealth.

Further, he has been lured to move from his native Australia to Silicon Valley by Stanford University engineering professor John Cioffi, the "father of DSL" who helped develop the chips in the first DSL modems.

Professor Cioffi reviewed Dr Papandriopoulos's PhD thesis and was so impressed that he called up the young super-genius and offered him a job at his start-up company, ASSIA. Dr. Papandriopoulos accepted and is now on his way to fame and fortune abroad.

His Australian alma mater has not forgotten about Dr. Papandriopoulos either. University of Melbourne gave him the Chancellor's Prize for Excellence, a prestigious award. It’s no secret why the University of Melbourne is so happy; Dr. Papandriopoulos is assigning the University of Melbourne his patents, however; he will still likely make big royalties from the licensing agreement he reaches with the university. The university is eagerly looking into commercializing Dr. Papandriopoulos's technologies. They are in talks with multiple vendors of DSL equipment and modems.

Dr. Papandriopoulos's technology revolves around the interference and cross-talk that occurs between the cable wires of high-speed ADSL (Asymmetric DSL) wires. This significant cross talk and the resulting interference forces providers to settle for lower speeds.

"That is not an issue for voice calls these days but it becomes a problem when you're trying to wring more bandwidth out of these existing copper telephone wires [which power ADSL broadband connections],” explains Dr. Papandriopoulos. “This cross-talk in current day DSL networks effectively produces noise onto other lines, and this noise reduces the speed of your connection."

He says that his technology is better that competitive solutions as it is more practical and easier to implement. He sees it coming to the market with 2 to 3 years.

Meanwhile, Professor Cioffi and Silicon Valley can't wait to put the Aussie to work in only two weeks, developing more brilliant solutions. With a mind like his, perhaps the sad state of broadband in the U.S. and abroad can be overcome, and be replaced with ultra-fast and efficient high-speed connections.

May be great stuff, but comments are a bit overdone.

1. There has been DSL technologies available that will do over 50-MBps for a long time. Just isn't implemented/used. Some only do it over shorter lines, but some are pretty fast over long lines as well.

2. Verizon is starting to install G-PON for FiOS. It's download speed is 2.4 Gbps and upload 1.2 Gbps and gets split up to 32 ways I think it was (it's split passively, the 'P' in PON so there's a limit on the number of splits). Remember that FiOS also is made to deliver a different HDTV signal channel to each house on the trunk, in addition to internet service and apparently other services they have in mind to roll out later. So they've some headroom -- but aren't going to cut their other revenue streams.

3. Advantage of copper pairs is that it's already there. Disadvantage is that often it's been there for a LONG time. The copper infrastructure apparently has relatively high maintenance compared to fiber. If it gets wet, it's bad -- fiber doesn't care. No crosstalk to even have to mathematically remove (and I suspect there are some assumptions in his algorithm that may not fully met in real systems).

4. All of these discussions are just the "last mile" link. From the central office (or not even there, perhaps in a neighborhood DSAM box) it's all shared resources (for internet service) and their OC-xx trunks probably won't be 100% dedicated to that one service (probably has the lowest QoS setting for that matter).
