1.3.1 Certified Wireless USB Overview
The WiMedia UWB specification first-generation data rate of 480 Mbps provides a basis
for delivering WUSB devices that can perform comparably with USB 2.0 devices.
The Certified Wireless-USB protocol maintains the same host-device model as the wired
USB protocol, but the Certified Wireless-USB protocol makes many optimizations for
operating efficiently on a wireless medium.
The first Certified Wireless-USB-protocol products are various Wire Adapter devices,
which operate as wired-to-wireless bridges. Host Wire Adapters (HWA) enable any PC
with USB 2.0 to become a WUSB Host. Device Wire Adapters (DWA) are wireless hubs
that can connect wired USB 2.0 devices to a WUSB Host.
For Certified Wireless-USB-protocol devices, UWBTracer/Trainer provides full protocol
decoding from low-level packets to high-level Wire Adapter transfers.
The WUSB specification is available from the USB Implementers Forum (USB-IF). The
URL for the USB-IF website is:

1.3.2 WLP Overview
WLP is a protocol that uses the services of the WiMedia MAC for data networking.
The WLP protocol uses the MUX sublayer and service defined in the WiMedia MAC
specification. The MUX sublayer combined with the WLP protocol corresponds to the
logical link control sublayer of the standard ISO/OSI IEEE 802 reference model.
For more information about the WLP protocol, MUX sublayer and service, and WiMedia
MAC specification, see the WLP specification at www.WiMedia.org.
