Research conducted at the Fraunhofer Institute for Communication Systems ESK could have paved the way for reduced broadband costs through the stabilisation of DSL access network connections.
The global broadband DSL access network consumes around 20 billion kilowatt-hours of energy every year, which has put pressure on telecommunications companies to investigate ways in which to reduce electricity outlay and cut overall costs.
While the use of a low-power mode (L2 mode) in standard ADSL2/ADSL2+ is already known to reduce DSL network electricity consumption, the technology has yet to be deployed due to problems with interference.
However, the German scientists believe they have found a solution to this conundrum which involves the use of artificial or virtual noise.
It is thought this method could help to reduce the electricity consumption of network operators by several million kilowatt-hours every year, thereby allowing the companies to make savings which could eventually be passed on to broadband users.
Verizon's fastest High Speed Internet service currently makes use of DSL technology, enabling download speeds of up to 7.1Mb.
