PHD student invents technology for 250Mbps DSL broadband

A PHD student in Australia has developed technology to make broadband over copper lines up to 200 times faster.

The technology was invented by Dr John Papandriopoulos, who has patent applications in progress for the technology.  He told the Melbourne Herald Sun newspaper that “Telephone wiring was poor quality and was not designed for high-speed internet when it was created”.

The technology uses mathematic modelling to reduce the interference in copper lines.  The new invention claims speeds of up to 250Mbps, and brings with it a rich array of new applications such as High Definition media content delivery.  BT’s copper-based telephone network which delivers DSL broadband services through copper lines, would benefit from such an invention. 

Inventions like this could also prove less costly than laying a new fibre-optic based cable network where it does not already exist.  However, BT has hinted in the last few months that it may look at installing fibre in the “last mile” of its network between telephone exchanges and users’ premises to improve overall line speeds.
