This document provides operational guidance for the AL5720
1.0 OVERVIEW
The AL5720 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.
The AL5720 Mini Docking Station provides connectivity for a standard DVI/VGA Video
Monitor, Stereo audio inputs/outputs and two USB 2.0 devices. This connectivity allows
the user to establish a wireless desktop for a UWB enabled computer.

4.0 SYSTEM REQUIREMENTS
The following specifications are necessary for each computer using the AL5720 Mini
Docking Station Solution:
• UWB-enabled PC or UWB host adapter such as the Alereon AL5604 Host Adapter
(USB) or the Alereon AL5705 Host Adapter (Expresscard).
• Windows XP with Service Pack 2 and the .NET Framework 2.0 installed or Windows
Vista.
• 1GHz (or greater) processor.

5.0 RANGE
In normal home and business environments, Alereon recommends that the AL5720 Mini
Docking Station 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 AL5604 USB dongle),
the AL5720 Mini Docking Station 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 AL5720 Mini Docking Station 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 AL5720 Mini Docking Station:

4 Alereon AL5720 UG Rev. 0.1
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 AL5720 Mini Docking Station not expressly
approved by Alereon can void the your warranty and place the AL5720 Mini Docking
Station 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 AL5720 Mini Docking Station 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 If necessary, consult your system
service representative or an experienced radio/television technician for additional help in
resolving interference.
