Alcatel-Lucent Gives DSL Networks a Gigabit Boost

coondoggie writes "Alcatel-Lucent and Telekom Austria have completed the world's first trial of G.fast, new technology enabling gigabit broadband over existing copper networks. The technology is only intended for distances up to 100 meters or 0.06 miles. But at that distance and less it helps copper keep up with fiber." It works, says the linked article, "by continuously analyzing the noise conditions on copper lines, and then creates a new anti-noise signal to cancel it out, much like noise-canceling headphones."

neat idea

The noise-cancelling scheme sounds interesting. The hardest part though is figuring out what exactly is noise - so it sounds like they would have to either invert the intended signal to cancel it out on the path to the noise measurement, or they would have to periodically turn the signal off so they can get a clean measure.

great announcement

Wow, so as long as you're in the same building as Alcatel Lucent, you're all set. You know, I think 802.11ac goes over 1 gigabit/s and reaches 100 meters on a good day. Maybe they should just go with that. I can't wait until fiber puts all these awful DSL companies out of business along with their ancient technology. AT&T really needs to go and TDS is pure evil too. Those are the big 2 around here. Time Warner's fiber backbone and 15 megabit coaxial-based internet for about $38/mo crushes them and yet some people are dumb enough to still go with AT&T and their legendary support and "pay 4x the value for your own modem up front and install it yourself" policy. You can actually get 50 megabit download speeds on a connection for under $100 around here too. Good luck with that, AT&T.
