Hi Frank: 40Mbps is only a rough number, but you are right, the total power has to be spread over a very large spectral band (2-4GHz) to ensure limited interference. The spreading is done by time hopping. Best regards, Bernard Levy

Hi Frank, The current UWB data rates are not explicitly regulated, and some claim development paths to several hundred Mbps by extending their current 20-50Mbps technologies. The late RadioLAN had plans to extend their 10Mbps to 100Mbps by coordinating pulse position energy in frequency, operating as a low-power 15.249 device, rather than a U-NII device(15.406). Search FCC Docket 98-153 for current status of the US UWB rulemaking. petere
