Aussies show off world’s fastest wireless link

Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) has achieved the world’s fastest wireless link.

The CSIRO ICT Centre today revealed it can get over six gigabits per second over a point to point wireless connection with the highest efficiency (2.4bits/s/Hz) ever achieved for such a system.

Multi-gigabit links operate at speeds that leave current wireless networks far behind. For example the entire works of Shakespeare could be transmitted over this six gigabit link in under seven thousandths of a second or a full DVD movie in just over three quarters of a second.

At the demonstration, the team will transmit 16 simultaneous streams of DVD quality video over a 250 metre link with no loss of quality or delays. This impressive demonstration nevertheless only utilises one quarter of the capacity of the link.

Dr Jay Guo, Director of the Wireless Technologies Laboratory at CSIRO said that this breakthrough is just a first stage towards direct connections of up to 12 gigabits per second.

“The system is suitable for situations where a high speed link is needed but it is too expensive or logistically difficult to lay fibre, such as in congested urban environments, and across valleys and rivers,” Dr Guo said.

“The system is also ideal for creating networks to meet short term needs such as emergencies and large events.”
