Site Survey Passive Mode Statistics
Description
Indicates the operational mode of your client adapter and the
name or MAC address of any associated access point.
Value: Not Associated, Associated, Authenticated, or
Note
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 following colors: green (strongest),
yellow (middle of the range), and red (weakest).
Range: 0 to 100% or –95 to –45 dBm
The signal quality for all received packets. The higher the value
and the more green the bar graph is, the clearer the signal.
The histogram below the bar graph provides a visual
interpretation of the current signal quality. Differences in signal
quality are indicated by the following colors: green (highest
quality), yellow (average), and red (lowest quality).
Range: 0 to 100%
Note
The level of background radio frequency energy in the 2.4-GHz
band. The lower the value and the more green the bar graph is, the
less background noise present.
The histogram below the bar graph provides a visual
interpretation of the current level of background noise.
Differences in background noise level are indicated by the
following colors: green (low noise), yellow (middle of the range),
and red (high noise).
Range: –100 to –45 dBm
