I think thats great for speed needs though. It doesnt beat fiber, but it may bring connection options to people in non-fiber areas.
Why any isp would not be connected to a fiber network is beyond me, but i guess its possible( in the US? ).
As you said, this will definitely help bring high speed connections to mobile tele towers. I would only comment that i know for a fact that sprint, verizon, at&t and altell are partnering with local fiber active companies to get fiber to their towers here in FL.
Ericsson claims 500Mbps speeds over copper
Summary
The communications company says it has demonstrated speeds of more than 500Mbps over copper infrastructure, using a new technology called 'vectorized' VDSL2.

Ericsson has successfully demonstrated data-transfer speeds of more than 500Mbps over copper, the communications company said on Monday.
The data-transfer rates were achieved using a version of digital subscriber line (DSL) technology called 'vectorized' VDSL2, Ericsson said in a statement. The technology, also called 'crosstalk cancellation', provides such high transmission rates through a twisted pair of copper cables by reducing the noise coming from other pairs in the same cable bundle. VDSL2 has traditionally offered speeds of around 100Mbps.
According to Ericsson, a benefit of vectorized VDSL2 lies in improved power management and lower power consumption, as the lines in a cable are decoupled in terms of interference. Claiming that the technology can work on existing copper lines, the company is pitching it at enterprise users and residential ISPs, as well as telecommunications companies building backhaul for mobile networks.
VDSL2 is a technology that some, such as BT, have mooted as a part of a nationwide, fibre-to-the-cabinet, next-generation access rollout. In this scenario, fibre connectivity would go as far as the street cabinet, while VDSL2 would then provide a high-speed connection between the cabinet and the customer premises. In August 2008, the telecoms regulator Ofcom said this approach could make 50Mbps connections a reality for the majority of the country.
Ericsson's vectorized VDSL2 tests produced aggregated rates of more than 500Mbps over a distance of 500 meters, with six lines bonded into one cable bundle.
"This demonstration confirms Ericsson's leadership in broadband-access technology and our commitment to the continued research and development of DSL technology to improve operators' business with new access solutions," said Ericsson's chief technology officer, Håkan Eriksson, in the statement. "It also proves Ericsson's abilities to provide future mobile backhauling, which will enable quick and cost-effective introduction of long-term evolution (LTE) solutions."
Ericsson also said in its statement that vectorized VDSL2 could be used by operators to "enhance fibre-access deployments with copper access in the last mile and thereby maximize the reuse of existing infrastructure".
While standards for VDSL2 and line bonding have already been established, vectoring will be standardized by the end of this year, Ericsson claimed in its statement.

You missed the whole point
This is in the UK, where they lag far behind the US in high speed broadband. Laying fiber across the UK is impractical and cost prohibitive.
This allows them to bring high speed Internet to remote areas outside of London and other large cities in the UK by reusing existing copper wire instead of laying all new fiber.

Umm, maybe
If TODAY'S technology allows for 100 Mbps over twisted pair, then how is bonding 6 pairs together a "new" technology? Been there, done that.
They already can do 10 Gbps over copper - although it's using "super clean" high purity copper - which isn't what is deployed to the English countryside. Of course, the taxes on the service is what will slow adoption in England . . .

How it is new technology
If you bundle 5 twisted pairs together, all running at 100MBS, without special technology you will have massive EMC problems. Take a class in RF engineering if you don't believe it.

Massive EMC problems?
My SAN will go down if my neighbor uses this?

RE: Ericsson claims 500Mbps speeds over copper
Get your facts straight, Ramjet. The CAT5 standard allows 100 Mbps up to a distance of 100 meters over two pairs. Ericsson claims 500Mbps up to a distance of 500 meters. Sounds like something 'NEW' to me.
