News: Nokia Siemens Networks boosts DSL speeds

Nokia Siemens Networks (NSN) has announced that it has successfully tested a technology that could dramatically boost the data carrying capacity of standard copper wires.

This technology enables data transmission speeds of 825 megabits per second (Mbps) over 400 meters of bonded copper lines and 750 Mbps over 500 meters. It enables a bandwidth increase of between 50-75% over existing bonded copper lines.

The company utilised circuits that allow for the creation of a virtual or ‘phantom’ channel to supplement the two physical wires that are the standard configuration for copper transmission lines. This approach is known as Phantom DSL and will be showcased during the Broadband World Forum 2010 that is taking place in Paris between 26 and 28 October.

“Laying down new optical fiber to the home remains costly, though it is capable of delivering very high speeds and is a definite solution for long-term bandwidth requirements,” said Eduard Scheiterer, head of broadband access business line, Nokia Siemens Networks.

“However, the innovative use of technologies such as phantom circuits helps operators provide an efficient last mile connectivity with existing copper wires.”

NSN stated that network operators could use this technology to optimise existing, widely deployed copper infrastructure in order to supply bandwidth-intensive services. These operators will also be able to prolong the lifespan of their existing copper networks, by delaying the need for fiber rollout.

In July NSN announced that it entered into an agreement with Motorola to acquire the majority of the company’s wireless network infrastructure assets for $1.2 billion (over R9 billion) in cash.
