2-10 AirDefense Mobile User Guide 184.108.40.206 Antenna Gain Located in the Antenna Gain tab is the Antenna Gain setting. A gain value (specified in dBi) can be specified to remove the antenna gain from the readings taken devices. This action allows the measurements taken from different devices to be brought to the same level (the gain value specified). For example, if two users were running sessions using a different network card with gain values of -2 and -3, the RSSI readings recorded would be offset by the corresponding values. Now, if the measurement files were to be visualized with another card with a gain value -2, all readings will be offset by a -2 gain value; thus, giving you a common gain value for the captured data being visualized.
Live Monitoring 2-220.127.116.11 Signal Propagation Assessment Located in the Signal Propagation Assessment tab is the Signal Propagation Assessment Distance setting. By entering a value (in feet or meters), you can set the distance, from your devices, that Mobile uses in a survey to collect measurement data. You may enter a maximum value of 65 feet or 20 meters.
