Aussie Claims Copper Broadband now 200x Faster 208
SkiifGeek writes "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."

So thanks, Mr. Aussie guy. You've breathed some life into the geriatric hobbling of copper. I hope you get a big payout, because you've basically done the equivalent of developing the world's fastest webserver running on Windows 95.

Plug a 3 kHz bandwidth and about 35 dB signal-to-noise ratio into the formula for channel capacity and you get about 35,000 bits per second. This is consistent with the last generation of analog modems (33.6 kb/s).
Now if the bandwidth is not artificially limited (remove transformers, filters, bridged taps, etc.) the theoretical capacity will increase by a large amount.

The only catch is that crosstalk is considered bad. Wires are often isolated in attempts to reduce or eliminate the problem. Furthermore, the signals are rarely processed by the same microprocessor, but are instead handled in parallel. Which means that we need a new infrastructure in order to support this new idea. (Assuming, of course, that the original poster is correct in his "guess" as to how this works. TFA is pretty light on details.)
That's the way I understood him, anyway.
