Site Survey Statistics
Description
The signal strength for all received packets. The higher the value
and the more green the bar graph is, the stronger the signal.
The histogram below the bar graph provides a visual
interpretation of the current signal strength. Differences in signal
strength are indicated by the height of the vertical bars (the taller
the bars, the stronger the signal).
Range: 0 to 100%
The percentage of beacon packets received versus those expected
to be received. The higher the value and the more green the bar
graph is, the better the quality of the signal.
The histogram below the bar graph provides a visual
interpretation of the current quality of the signal. Differences in
signal quality are indicated by the height of the vertical bars (the
taller the bars, the stronger the signal).
Example: The access point sends out 10 beacons per second, so
you would expect the client adapter to receive 50 beacon packets
in 5 seconds. If it receives only 40 packets, the percentage of
beacons received would be 80%.
Range: 0 to 100%
