What is ultrawideband?
Ultra-wideband (UWB) is a technology for transmitting information over a large bandwidth (>500MHz) that should, in theory and under the right circumstances, be able to share spectrum with other users. UWB is ideally suited for streaming multimedia in the wireless home or office environment.
