> Ultra-wideband (UWB) transmission, if approved by the FCC, could
> lead to the development of technology with throughput capacity
> far superior to 802.11b wireless LANs. In turn, 802.11b and
> short-wave Bluetooth radios could be replaced with UWB products
> that offer lower costs, higher bandwidth, and greater user
> support. UWB transmissions do not involve carrier signals,
> and thus eliminate crowding. Furthermore, University of Texas
> researcher Douglas Cummings said that UWB transmitters and
> receivers have relatively few construction, operational, and
> maintenance needs. The power requirements are also small,
> in the 50- to 70-milliwatt range, according to Time Domain
> technologist Adrian Jennings. In addition, since pulse
> signals blend so easily into background electronic noise, UWB
> transmissions are well protected. Still, there are worries that
> UWB devices operating below 2 GHz will break into global
> positioning system, air traffic, television, and other broadcasts.
