The Nortel WLAN Location Engine 2340(WLE2340) tracks all powered 802.11 devices that registered Location APs
detect. In order to understand how this is accomplished, it is helpful to take a brief look at the following core concepts
and features:
• The patented Tracking Engine, which pinpoints the exact location of any 802.11 wireless device.
• Tracking Precision, options for reporting a device's location.
• Locales, the areas under surveillance in and around your company.
• RF Fingerprints, the RF data that Tracking Engine uses to identify each locale.
• Calibration, the process whereby the Tracking Engine collects RF Fingerprint data.
• The Evaluator, which verifies that the Calibration captures enough useful data.
• Walkthroughs, in which Tracking accuracy is verified.
• Location APs, Access Points used to detect and report 802.11 traffic.
Tracking Engine
The Tracking Engine, based on patented technology, powers the Nortel WLE2340. It recognizes the locale of each
wireless device by matching the RF Fingerprint of the device to the RF Fingerprints it has on file for each Locale. These
fingerprints are created automatically by the Tracking Engine during the calibration phase. It is able to account for the
noise, interference, variance, and 'bouncing around' characteristics of the 802.11 band, thus assuring an accurate match.
