Configuring APs to be AeroScout
listeners
AeroScout RFID tags are wireless transmitters that you can place on assets such as office equipment to track the equip-
ment’s location. Each tag regularly transmits its unique ID. AeroScout listeners detect the transmissions from the RFID
tags and relay this information to an AeroScout Engine or WSS. You can use an AeroScout Engine or WLAN Manage-
ment Software to locate the asset.
APs can be configured as AeroScout listeners. An AP configured to be an AeroScout listener detects RFID tag IDs and
sends the tag information to the WSS managing the AP. If an AeroScout Engine is configured to request the information
from the AP, the AP also sends the information to the AeroScout Engine.
The accuracy of the location information depends on the number of listeners (APs). Nortel recommends that you
configure at least three listeners.
Configuring AP radios to listen for AeroScout RFID tags
To configure AP radios to listen for AeroScout RFID tags:
• Configure a service profile for the AeroScout listeners and set the SSID type to clear (unencrypted).
• Configure a radio profile for the AeroScout listeners.
● Disable Auto-RF of channels on the service profile. Channels on RFID tags are statically configured.
Therefore, the listener should not dynamically change channels.
● Disable Scheduled RF Scanning on the service profile. When Scheduled RF Scanning is enabled,
radios go off-channel for brief intervals to scan for rogues.
● Enable RFID mode on the service profile. RFID mode allows AP radios to accept Aeroscout Engine
commands. An AP will forward RFID tags to an Aeroscout Engine after receiving an Enable Access
Point command from the Aeroscout Engine.
● Map the AeroScout listeners’ service profile to the radio profile.

Note. You can configure APs or directly connected APs to listen for RFID tags. However,
if you plan to use an AeroScout Engine to display asset locations, you must use Distributed
APs. RFID tag information from directly connected APs is available only to WLAN
Management Software.You must manually configure a unique static IP address for each AP
designated as a listener.
