[ Reality distortion is a mild description djf]
[Note: Well, after months of silence, the flames are being fanned for UWB, complete with the usual reality distortions. DLH] ULTRAFAST WIRELESS TECHNOLOGY SET TO LIFT OFF 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. (Network World, 27 August 2001)
