World-First VDSL2 Demo Gets 500Mbps Data Transfers 110
pnorth writes "Ericsson has achieved data transfer rates of more than 500Mbps in what it said is the world's first live demonstration of a new VDSL2-based technology. The demonstration achieved data rates of more than 0.5 Gbps over twisted copper pairs using 'vectorized' VDSL2. Vectoring decouples the lines in a cable (from an interference point of view), substantially improving power management, and reduces noise originating from the other copper pairs in the same cable bundle."

"Where the technology does have great applications is among Fibre-to-the-Building deployments in commercial areas.
"You might have fibre connected from the DSLAM to the basement of an office building," Goodwin said. "You can then run bonded VDSL2+ up into all the other floors.""
Apparently it's cheaper to roll out fibre to the home these days for new installs and the existing copper to the home is insufficient for last mile where there is fibre to the street (junction)...so looks like it's great for business use or specific regions which fit into some window of installation where they put in redundant copper to the home with fibre to the street.

Not so spread out. Examine a map of population distribution [wikipedia.org]. Note all the white and yellow around the middle and all the blue along the coasts and readjust your math.
It's not as dense as Japan by any means, but upgrading infrastructure is plenty feasible, provided you can dislodge the incumbent interests.

DSL is for:
-People who don't care how fast their connection is so much as that the connection is up and running
-People who want a generally fast Internet connection that provides a reliable amount of bandwidth
-People who don't want, or can't afford, to put up with download caps
-People who are not serviced by a cable company (rural farmers, people who don't live in a big city, etc...)
-People who want a static IP address without buying into a business package (depends on the DSL providers, of course)
-People who are sick of paying $90/month for 20/1 cable service when they only get 7/512 on the best days because the local cable loop is over saturated, so they opt to pay $120 for 15/1 ADSL2+ and generally get more bandwidth
-People who are not going to pay ISDN prices to get more bandwidth than 56k dialup.
-People who don't care about their Demonoid share ratios and don't make piracy a necessary part of their lives.
-People who realize that while they could download that latest UBuntu ISO faster on a cable connection, they're still going to forget about the download and do something else, until tomorrow when they suddenly remember "oh yeah, that Ubuntu CD..."
-People that actually like gaming and don't want to be throttled back by their cable company for "unusual traffic usage patterns"
-People that runs servers as a hobby and don't have the means to pay for a full business class service (and, in reality, don't need to)
Generally, DSL isn't for the person who absolutely needs to use every ounce of bandwidth available to them. If you need to listen to streaming radio, while sharing 75 files on BitTorrent, playing YouTube videos on a second monitor while you run around WoW leveling up.
