Local whiz speeds up broadband by 200 times

October 29, 2007 | Chris Payatagool

Harnessing the potential power of telephone lines and DSL broadband, the technology will deliver internet speeds up to 250 megabits per second, compared with current typical speeds of between one and 20 megabits per second.

Dr John Papandriopoulos, who has patent applications for the technology being processed in the US and Australia, won one of Melbourne University's top academic prizes yesterday, a Chancellor's Prize for Excellence in the PhD.

Telephone wiring was poor quality and was not designed for high-speed internet when it was created, Dr Papandriopoulos said.

"Back in the old days, if you picked up the phone you could hear your neighbour's conversation from cross-talking interference," he said.

"While that doesn't happen any more with voice calls, it does with the broadband internet - your telephone line interferes with your neighbours and everyone in your street's internet."

Dr Papandriopoulos' research, which took a year to complete, uses mathematic modelling to reduce the interference that slows down downloading.
