Ofcom - UWB interference report

The Ofcom-commissioned report into possible interference of Ultra Wide Band (UWB) on Broadband Fixed Wireless Access (BFWA) is now available at: http://www.ofcom.org.uk/research/technology/cet/uwb/background_uwb_rpt/

Summary of Economic Evaluation:

Radio Amateurs have of course been arguing that UWB would cause unacceptable degradation to the noise floor which would adversly affect weak signal working.

I was glad to see the report acknowledges the considerable harm that UWB would cause to the comparitively strong signal BFWA services.

While 'detect & avoid' would be an improvement on current proposals, restricting operation to above 6 GHz should be the prefered solution. Although the report says that no chipsets are currently being designed for 6+ GHz, this
is incorrect, they are.

Chipsets for 6+ GHz will be widely available in a far shorter timescale than the 5 years the report envisages.
