500Mbps Internet over phone lines might solve fiber’s “last mile” problem
G.fast promises fiber-like speeds without fiber to the home.

The International Telecommunication Union (ITU) yesterday gave initial approval to a data transmission standard capable of 500Mbps speeds in both directions over existing telephone wires. The new standard, G.fast, can be used on phone lines within 250 meters of a distribution point, benefiting fiber-to-the-node deployments. With telcos not having to build fiber on the proverbial "last mile" (or, really, 250 meters), this could bring fiber-like speeds to many more homes.
Huawei has been working on developing G.fast since 2010 and says it had a prototype delivering gigabit (combined upstream and downstream) speeds over 100 meters of copper by 2011. Huawei announced two months ago that BT is trialing its G.fast technology. Alcatel-Lucent and Telekom Austria Group announced a similar trial in July of this year.
The ITU's G.fast group has seen participation "from a large number of operators, chipset manufacturers, and equipment suppliers," Huawei said. D-Link says that it's "working today with selective Operators to achieve FTTdp deployment and trials" using G.fast.
A new company, called Sckipio, was founded last year to build G.fast chips, on the belief that it will become a booming business because it's more cost-effective than fiber-to-the-home. "[A]s fiber nodes move closer to the home, it is becoming obvious the cost to deploy fiber for the last 250 meters is prohibitive," Sckipio says. "According to some accounts, over 80 percent of the cost to deploy fiber is based upon this last segment.
