34 Nortel WLAN Location Engine 2340 Web GUINN47250-504 (324122-A Version 01.01)Use as many locale elements as desired.Channel scanningWhen calibrating, Location APs can scan the same channel that the Access Points scan. (After Nortel WLAN LocationEngine is fully deployed and operational, Location APs can be set to scan on one or more 802.11 bands).RF FingerprintsThe Calibration RF Fingerprints page allows you to name RF fingerprints and bind them to locales without capturing theRF data required for calibrating the Tracking Engine. This allows the capturing of RF fingerprint data to be handled by adifferent person from the person who is selecting the locale and RF fingerprint names. An RF fingerprint is consideredempty until the RF data that characterizes it has been captured.To capture RF data for each RF fingerprint, the personnel responsible for the calibration phase of the deployment canphysically walk through the area to be monitored. Nortel recommends holding a wireless device broadcasting on thescanned channel. If the device cannot open a browser page to the Nortel WLAN Location Engine Console, then a seconddevice or individual must initiate the calibration process through the Nortel WLAN Location Engine Console.Note. The description attribute can be blank, but each name can have a value.Note. Before capturing RF fingerprints, create network traffic by starting acontinuous ping between the wireless client and the server.
