The location of a particular device can be tracked using the location tracking feature. The system needs at least three
sensors to perform location tracking. The Location Tracking screen enables you to define the parameters that control
location tracking.
Location Tracking
Default Location Tracking Parameters contains the following options:
 Location Tracking Technique: Select the technique used for location tracking. The technique available is
Generalized Likelihood.
 Maximum number of Sensors to use for Location Tracking: Select the maximum number of sensors used
for location tracking. Sensors track down the location of a device and the system uses sensors that see the
maximum values. A higher value is likely to give better results.
(Minimum: 3; Maximum: 10; Default: 4)
 Default Transmit Power of AP (mW): Location tracking needs as input the transmit power of the AP being
located. When transmit power is unknown, the default value set here is used.
(Minimum: 1 mW/0 dBm; Maximum: 100 mW/20 dBm; Default: 30 mW/15 dBm)
 Default Transmit Power of Client (mW): Location tracking needs as input the transmit power of the Client
being located. When transmit power is unknown, the default value set here is used.
(Minimum: 1 mW/0 dBm; Maximum: 100 mW/20 dBm; Default: 10 mW/ dBm)
 Signal Strength Monitoring Devices: Location tracking is based on the signal strength of the monitoring
devices. This value can deviate from the actual values because of subtle variations in the RF environment.
You can specify APs only, Sensors only, and Sensors and/or APs to be used to control location tracking.
Using the system’s Application Programming Interface (API), APs can be reported as a source of signal
strength. Information from these APs can be used for location tracking.
