Aussie Claims Copper Broadband now 200x Faster
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."

Given what I've seen in the past and knowing how greedy telecommunications companies are, I doubt the above statement.
It could on cost. Using fiber in many areas requires that you lay new lines. Even if it's not quite as fast as copper, or has a little more latency (light is faster than electrical signals), you could probably make quite a bit of money since there's a much smaller investment.

Not true... information theory shows that a fractional bit is a probability of transmitting the desired bit correctly. A true source of random noise generates no bits, but a highly noisy channel transmits fractional bits per noisy bit sent. Fractional bits are well-founded mathematically.
Beer is proof that God loves us, and wants us to be happy.
That's only true if the bandwidth is limited to 3 kHz, as it is in voice circuits.
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.
Summary: You have to do a bunch of math, like, real fast, and it might not even work if all the signals don't go through the same thingy.

If I hadn't already posted to this story I'd be trying right now to figure out how to use my two remaining mod points to mod you both funny and insightful.
I see even classic Slashdot is now pretty much unusable on dial up anymore.
