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.

Ok Doc, now can you work on methods and application for extending the distance from a node that ADSL signals can travel? Perhaps extending into the 20 mile range?

For those of us who live a bit more distant from town, such a thing could be a real boon to connectivity! My WiMAX is good, but competition never hurt!

Actually this research should already address your issue. It should increase the speed for people who can use it now, and allow people who couldn't use it because they live too far to hop on board. Too much interference (low signal/noise ratio) is the main reason you can't use ADSL if you're 5km or more away from the central office (used to be 5km 10 years ago, no idea what it's now).

That's my understanding at least, I haven't read the paper but I probably will as I'm interested in what he did.
