Default Description
When VisualRF locates a client or rogue it utilizes signal metrics from all the APs that
hear the client or rogue device. VisualRF builds a fingerprint location for all clients with
similar transmit-power capability. All subsequent clients that fall within the deviation is
placed on the same location fingerprint or x, y coordinates.
Example: AP1 hears Client1 at -72, and AP2 hears Client 1 at -64. VisualRF calculates the
4 dB
client's location to be at coordinates 100, 200. Client2 is heard by AP1 at -71 and AP2 at -
65.
VisualRF will use the average of the difference in signals (AP1 -72 and -71) to see if the
client matches a pre-calculated location fingerprint. 1 + 1 (differences in signals) / 2 (# of
APs) = 1 which falls within the deviation of 2, hence the client would be located at 100,
200.
Sets the maximum number of rogues AirWave will place on a Floor. Use this filter in
combination with the RAPIDS Export Threshold configured on the RAPIDS > Setup page
20 to intelligently control the number of rogue devices displayed per floor.
NOTE: Increasing this value can increase the load on the server and the clutter on the
screen.
