1 Introduction
This document describes the system operation of a Wireless USB Module, as well as driver
installation and the use of control software.
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 System Block Diagram (with a Carrier Board)
The following figure shows the system block diagram of a Wireless USB Module and a carrier
board. It accepts +5V from a power adapter or +5V from USB device and converts it to various
voltages required by the MAC-PHY chip.
Only one crystal is used in the system, which is 66MHz. The system is designed to support both
BG1 and BG3 UWB bands as defined in the WiMedia standard.

3 Driver Installation
3.1.Setup the USB connection between the PC and Wireless USB Module.
3.2.Power up Wireless USB Module by inserting the connection between the mini-USB
receptacle and the PC. The mini-USB supplies the +5Vdc to the three regulators on the
carrier board, which then convert it to various voltages required by the MAC-PHY chip.
3.3.Follow the steps below for the driver installation process.
STEP 1. After plugged in the mini-USB connector, Windows will prompt to install driver for the
Found New Hardware Wizard.
