3.4 Description
The DC20 UWB Radio Module is a pre-test radio module which can be used for both host and device
side applications. It supports both driver based solutions with Alereon’s Wireless USB Manager User
application for Microsoft operating systems or Alereon’s NoWire™ driverless firmware solutions for OS
independent Wireless USB or IP based WLP applications.
The DC20 is based upon Alereon AL5100 UWB Radio Transceiver and the Alereon AL6301
MAC/Baseband. It supports UWB/WiMedia Band Groups 1, 3 and 6 to provide 10 or more channels of

DC20 Dongle 9 of 14
operation in any country of the world. The card requires a single 3.3 volt power supply and provides a
standard USB 2.0 downstream interface to USB devices.
The DC20 is a versatile design that can support a variety of applications. There are several different
Firmware (FW) options that can be selected depending on the specific application and product feature set
requirements. For standard Wireless USB applications, the Host side radio but be programmed with HWA
Firmware while the Device side radio must contain DWA Firmware. A strapping resistor must also be
configured to determine either Host or Device operation (See Notes on Pin-out table below). Other driverless
Firmware options are available depending on specific downstream class types, operating systems and
protocol requirements for the specific application.

6. Cautions
This device uses ultra high frequency radio. Therefore if there’s an object like concrete wall or furniture
etc, between USB dongle and receiver device, the radio performance will be decreased much. Any
obstacle objects should not be between USB dongle and receiver. The operating range is 5~10m and it
can be varied according the environment.
