Melbourne researcher awarded for DSL innovation

A discovery that paves the way for DSL networks up 100 times the speed of current ADSL and ADSL2+ networks has won a Melbournian researcher the University of Melbourne's top academic prize.

A discovery that paves the way for DSL networks up 100 times the speed of current ADSL and ADSL2+ networks has won a Melbournian researcher the University of Melbourne's top academic prize.

Dr John Papandriopoulos' discovery would increase broadband speed without multi-billion dollar investments in cabling infrastructure.

Based on his research, he says the new technology could deliver between 100 and 250 megabits per second - compared to current Australian DSL which ranges from one megabit to 20 megabits per second.

He has patented the technology in Australia and the US and will today be presented with a Chancellor's Prize for Excellence in the PhD.

Dr Papandriopoulos developed two methods, which he has patented as SCALE and SCAPE, as part of his PhD in the university's Department of Electrical and Electronic Engineering.

The new techniques operate by dramatically reducing the interference which slows down data transmission in current DSL networks.

Dr Papandriopoulos developed the system using complex mathematical modelling and optimisation techniques, which he says can be used with existing telecommunications networks without laying kilometres of expensive fibre-optic cabling.

To utilise the new system, telecommunications providers would need to change their operational systems and consumers would need to purchase new modems.

Dr Papandriopoulos completed his PhD in 2006. He has since worked as a researcher in the university's Centre for Ultra Broadband Information Networks.

Next month, he will take up a new position in the United States working for a start-up company founded by Stanford University Professor John Cioffi, the so-called 'father of DSL'.
