Figure 3-14. Site Survey Graph
The minimum measurable RSSI of the system is approximately -103 dBm. An RSSI level
higher than -103 indicates interference. The difference between the level of interference to -
103 dBm affects the sensitivity in that frequency. In the above graph, the channel with the
most interferences (channel 46) has the maximum RSSI level of -94 dBm, while the minimal
RSSI level of the system is -103 dBm. The difference is 9 dB. Therefore the sensitivity of the
device in that frequency decreases by approximately 9 dB. To enter the Site Survey Mode,
select 2 in the Mode and Access Control Menu and reset the unit. The system start collecting
information on received interference levels in applicable channels and displays the histogram.
To exit the Site Survey Mode, select 3 in the Mode and Access Control Menu and reset the
unit.
Note: The main menu header indicates whether you are in Site Survey Mode or in
Normal Mode.
