The Wireless USB specification was recently completed by the Wireless USB Promoter Group. The USB Implementers Forum will now take over the spec for certification, compliance testing, logo licensing and marketing for Wireless USB. The first Wireless USB products are expected by the end of the year.
Wireless USB runs over the WiMedia Alliance's flavor of ultrawideband which uses the WiMedia MB-OFDM MAC and PHY. The WiMedia Alliance's version of UWB promises bandwidth of 480Mb/s at 3 meters and 110Mb/s at 10 meters.
