From physorg.com, the CSIRO ICT Centre today announced that it has achieved 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.
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 operates at 85GHz in the millimetre-wave part of the electromagnetic spectrum (above 55 GHz) which offers the potential for these enormous speeds and is not yet congested by other uses.
