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.

Airecomm is faster the FIOS. It's just expensive. It can go up to 60Mbps. Airecomm uses a satellite to transfer data. It has the same fidelity as XM and Sirus so it is certainly fast.

If they use Geosynchronous satellites then the latencies are also at minimum 1/2 of a second, are probably dependent on weather, and possibly require costly fees to re-align in case of extreme weather conditions causing the antenna to move.

Exactly. And it's not faster than FIOS. FIOS is deliberately limited by the ISP, it could easily do 10GB/s, it doesn't for commercial reasons not technical ones.

Not only that, but because of the way most TCP connections work the latency works against available bandwidth too. Unless the satellite company dedicates special hardware to correcting the situation for EACH customer, TCP-IP only allows 3 packets in-flight at the same time. With high latency that limits a socket connection over satellite you can only get about 200K per second, maximum, regardless of the channel size.

Many satellite connections "cheat" by somehow pre-acknowledging packets. I'm not exactly sure how it works, it's just what I've been told. I work in a satellite internet company and I often see download speeds in excess of 1mb, so at least my particular company seems to have gotten around that limitation.

Um... yeah he said 200K as in kilobytes = 1.6 Mbps. That's more than the highest speed I ever saw when I was using DirecPC/Hughes. And as he and others said, the latency is ABSOLUTELY MISERABLE. My average ping times were around 850ms-1000ms... totally rotten. It was unique back in the mid 90's when 400kbps down blew away a 56k modem. (the older systems were only 1-way.. had to use a dialup for the uplink)
When they went two way the uploads went to 150-300kbps but the latency was even worse. All in all, a pretty bad experience once cable and DSL service started rolling out in the late 90's and early 2000's. I wouldn't recommend it to ANYONE.
