>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.
