Document Overview
This document describes the Alereon AL4504 Dongle.
1.0 WIRELESS USB/ULTRA-WIDEBAND OVERVIEW
The AL4504 Dongle allows Ultra-wideband (UWB) wireless data transfer between two devices, as well
as interoperability with other Certified Wireless USB devices. Certified Wireless USB is the new wireless
extension to USB, combining the speed and security of wired USB technology with the convenience and
ease-of-use of wireless. Certified Wireless USB supports robust high-speed wireless connectivity by
utilizing the common WiMedia UWB radio platform developed by the WiMedia Alliance. UWB
technology offers a solution for high bandwidth, low cost, and low power consumption. Certified
Wireless USB is the first high-speed wireless personal interconnect technology to meet the needs of
multimedia consumer electronics, PC peripherals, and mobile devices. Certified Wireless USB
preserves the functionality of wired USB while eliminating the tangle of cable connections.
2.0 PACKAGE CONTENTS
The AL4504 Dongle is shown in Figure 1.

4.0 SYSTEM REQUIREMENTS
The following specifications are necessary for each computer using the AL4504 Dongle:
• USB-equipped PC
• Windows XP with Service Pack 2 and the .NET Framework 2.0 installed*
• 1GHz (or greater) processor
• 256MB (or more) memory
• At least 50MB of free hard-drive space
• At least one other Certified Wireless USB host device with which to communicate
*Note: Drivers for Windows Vista have not yet been released, but will be before the end of 2007.
5.0 RANGE
In normal home and business environments, Alereon recommends that the AL4504 Dongle be placed
within 10 meters of a Certified Wireless USB host for optimal operations. Under ideal circumstances,
and with the right host, the AL4504 Dongle is capable of significantly longer ranges, but these are not
guaranteed. Likewise, in environments with heavy EMF shielding or significant radio frequency (RF)
noise, the dongle and other UWB devices may need to be placed closer together for optimal
performance.
6.0 SETUP
Perform the following steps to get your AL4504 Dongle up and running:
1. Remove the dongle from the packaging and inspect it for damage. If it appears to have been
damaged in shipping, please contact Alereon Technical Support via this web form:
http://www.alereon.com/contact-us/
2. Put the Documentation/Software CD into the PC to which you wish to attach the dongle. An
install program will automatically start running after insertion. (If not, please double-click on the
program icon on the CD, or reset your permissions to allow the program to run.)
3. Follow the on-screen instructions to install the driver and software for the dongle.
4. Attach the dongle to the PC by plugging it into the USB port.
5. Once you have finished these steps, your AL4504 Dongle should be capable of working with
another Wireless USB device.

8.2.2 Electromagnetic Interference Control
Electromagnetic Interference (EMI) is any signal or emission, radiated in free space or conducted along
power or signal leads, which endangers the function of radio navigation or other safety service (the
telephone and cellphones are considered to be safety services) or seriously degrades, obstructs or
repeatedly interrupts a licensed radio communications service. Radio communications services include
but are not limited to: AM/FM commercial broadcast, television, cellular services, radar, air traffic
control, pager and personal communications services (PCS). These licensed services, along with
unintentional radiators such as digital devices, including computer systems, contribute to the
electromagnetic environment.
Electromagnetic Compatibility (EMC) is the ability of items of electronic equipment to function properly
together in the electromagnetic environment. While the AL4504 Dongle has been designed and
determined to be compliant with regulatory agency limits for EMI, there is no guarantee that interference
will not occur in a particular installation. If they do cause interference with radio communications
services, which can be determined by turning the device on and off, you are encouraged to try to correct
the interference by one or more of the following measures:
• Reorient the receiving antenna
• Relocate the device with respect to the victim receiver
• Move the device away from the victim receiver
• Plug the device host into a different power outlet than the victim receiver so that the device
system and receiver are on separate branch circuits
If necessary, consult your system service representative or an experienced radio/television technician
for additional help in resolving interference.
9.0 TROUBLESHOOTING
Below are troubleshooting steps to resolve the most common problems with your AL4504 Dongle.
9.1 Installation Software Does Not Start After CD Inserted
If the CD-ROM does not start the Alereon Software Installation program automatically, other
applications could be interfering with the CD drive. If the Alereon Software Installation screen does not
appear within 30 seconds, double-click on the “My Computer” icon. Next, double-click on the CD-ROM
drive in which the Installation CD has been placed to start the installation. If the installation does not
start automatically, right-click to select “Explore”, then double-click on the installation icon.
9.2 Power LED Does Not Light Up; Dongle Not Working
If the LED indicator does not light up, your dongle may not be connected. Verify that the dongle is
plugged firmly into the USB port of your computer. Check to see that the drivers have been installed.
Right-click on the “My Computer” icon on your desktop. Choose “Properties” and navigate to the
“Device Manager” and see if the Alereon AL4504 Dongle is listed without any errors. If an error is
indicated, contact Alereon technical support, as indicated in Section 6.0.
9.3 Certified Wireless USB Link Not Working
If the dongle is powered-up properly, but the Certified Wireless USB link is not working, make sure that
at least one Certified Wireless USB host device is up and working properly. If you have verified that it’s
working, see the Alereon Software Guide for information on troubleshooting wireless connections.
9.4 Other Software Errors
For other software errors or driver difficulties, please see the Alereon Software Guide.
