"People have been trying to push up the speeds of broadband to as fast as possible by pushing the actual bandwidth limits," Papandriopoulos tells Image and Data Manager Online. "The underlying problem is really one of interference, in effect your neighbor is interfering with your speed," he said. A bit more from the report:
An Australian PhD student has devised a way of getting extra bandwidth out of copper. Dr John Papandriopoulos, who is waiting for patents to get processed on his technology, says it could provide speeds up to 250Mbps over traditional copper lines. The article, which offers scant technical specifics, says the technology "uses mathematic modeling to reduce the interference that slows down downloading."
"Winner of Melbourne University's Chancellor's Prize for Excellence, Dr John Papandriopoulos could soon find himself the focus of a number of networking companies and government agencies interested in wringing more performance from existing network infrastructure. Dr John developed a set of algorithms (US and Aussie patents pending) that reduce the impact of cross talk on data streams sharing the same physical copper line, taking less than a year to achieve the breakthrough. It is claimed that the algorithms can produce up to 200x improvement over existing copper broadband performance (quoted as being between one and 25 mbit/sec), with up to 200 mbit/sec apparently being deliverable. If the mathematical theories are within even an order of magnitude of the actual gains achieved, Dr John's work is likely to have widespread implications for future bandwidth availability across the globe."

John Papandriopoulos was born in Melbourne, Australia, in 1978. He received the combined B.E. degree in communications engineering and B.App.Sci. degree in computer science from the Royal Melbourne Institute of Technology (RMIT University), Australia, in 2001 and was awarded the J. N. McNicol Prize (University Medal) in 2002.
He completed his Ph.D. in 2006 within the Department of Electrical and Electronic Engineering at the University of Melbourne, Australia. His research interests include non-linear (non)convex optimization techniques and applications, particularly in the cross-layer design of wireless networks and resource allocation in CDMA and OFDM-based networks.
John has worked with Telstra, Agilent Technologies, and the 3G Mobile R&D Division of NEC Australia. He has also served two years as the Chairperson of the University of Melbourne IEEE Student Branch from 2003.
