From the Times today,

"The Civil Aviation Authority, Britain’s air safety regulator, said that portable electronic devices such as laptops and personal organisers might have to be prohibited because of the risks posed by ultra wideband (UWB).
Tests on Boeing 737 and 747 aircraft by Nasa and United Airlines in California found that UWB devices “knocked out” the collision-avoidance system, which warns the pilot of converging aircraft, and the instrument landing system that guides aircraft to runways in bad weather. UWB may also interfere with air traffic control systems that rely on satellite signals. "
Has anyone been involved in UWB avionics testing here? I want to follow this story up: it seems to be based on a story in Aviation Now in June which seems to say the testing was rather ad-hoc (they had to turn the power up to many times the FCC limits for UWB, for example), but so far I haven't found the original research online and NASA is still asleep...
