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

see link in story: http://news.zdnet.co.uk/story/0,,t269-s2106347,00.html 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. |
