New evidence may ban laptops in planes

http://netscape.com.com/2100-1105-956300.html?type=pt

Quote:
Britain's Civil Aviation Authority is considering implementing the ban following research carried out earlier this year by NASA scientists into UWB. The ban was first reported in Monday's The Times newspaper. The researchers, based at NASA Langley, found evidence that UWB devices could affect a plane's electronics, including its instrument landing system and its collision avoidance systems.

...

All laptop use might have to be stopped, because air crews could not be expected to tell which laptops might include a UWB chip and which might not, so a blanket ban could be the only answer.

If they can't think of another solution, it seems that they're not trying very hard.

UWB is a radical radio technique that transmits a stream of very low power pulses without a central frequency. Theoretically, these could be broadcast anywhere in the entire radio spectrum, but concerns about interference with existing services means that they have to avoid some areas such as those used by satellite navigation systems and cellphones, with most of the transmitter power falling between 3GHz and 10GHz where existing services are fewest. Spectrum owners are concerned about UWB both because of the potential of interference, and because UWB is in effect using parts of the radio spectrum that the existing owners have paid for.
