Certified Wireless USB can operate in two way:

Coexistence Wireless USB operates on top of Wimedia UWB PHY - Wimedia UWB MAC - Convergence Layer. Pure Wireless USB operates directly on top of Wimedia UWB PHY.

I wonder where this distinction comes from. Currently there's only 1 Certified Wireless USB implementation. This seems to be the one referred to here as Coexistence Wireless USB.

Probably this refers to current CWUSB model where CWUSB devices can be WiMedia MAC&PHY aware and participate to the WiMedia MAC beaconing and other channel management or CWUSB device may be not aware of this and are only understanding CWUSB related data transfer (sending WiMedia beacons according to instructions sent by host or not sending WiMedia MAC beacons at all). CWUSB hosts are always WiMedia MAC&PHY aware to faciliate coexistence with other PALs using WiMedia UWB.
