Wireless USB Module_TheoryOfOperation.doc Wireless USB Module Theory of Operation Rev 1 1 All Rights Reserved by Realtek Semiconductor Corp. Wireless USB Module_TheoryOfOperation.doc 1 Introduction This document describes how the system operates as a UWB (Ultra-wideband) device. 2 System Operation 2.1 General Description Wireless USB Module is a UWB module. It can be used in various UWB applications, such as 4-port HWA and WUSB docking station. 2.2 Operation A UWB module can operate in both BG1 and BG3. Only one of the band groups will be operating at a given time and this is determined by the MAC-PHY chip. It searches for WiMedia standard-compliant UWB hosts that have associated relationship with it. Once such a host is found, the communication link will be set up and the USB device, e.g. a flash drive attached to the UWB module, can be accessed by the host (computer). 2 All Rights Reserved by Realtek Semiconductor Corp.
