Document Overview
This document describes the Alereon AL4512 UWB Hub.
1.0 WIRELESS USB/ULTRA-WIDEBAND OVERVIEW
The AL4512 Hub allows Ultra-wideband (UWB) wireless data transfer and 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 connivance 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
Your AL4512 Hub Solution package should contain all the items shown in Figure 1. In addition, there
will be a CD containing all software (including drivers) and documentation for the AL4512 Hub. See

4.0 SYSTEM REQUIREMENTS
The following specifications are necessary for each computer using the AL4512 Hub Solution:

5.0 RANGE
In normal home and business environments, Alereon recommends that the AL4512 hub be placed
within 10 meters of the Certified Wireless USB devices with which it is communicating for best
operations. Under ideal circumstances and with properly configured Certified Wireless USB devices
(such as the AL4504 USB dongle), the AL4512 Hub 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 hub and other Certified Wireless USB devices may need to be placed closer together
for optimal performance.

8.0 FCC COMPLIANCE
8.1 Compliance Statement
The following compliance statement applies to the AL4512 Hub:
This device complies with part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that
may cause undesired operation.
8.2 FCC Requirements
8.2.1 Modification Voids Compliance Warning
Warning: Changes or modifications to the AL4512 Hub not expressly approved by Alereon can void the
your warranty and place the AL4512 Hub outside FCC equipment authorization.
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 AL4512 Hub 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 it does 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

for additional help in resolving interference.
9.0 TROUBLESHOOTING
Below are troubleshooting steps to resolve the most common problems with your AL4512 Hub.
