Using the Associated AP Status Tab

Table F-1 Site Survey Utility - Associated AP Status (continued)

Associated AP Status Parameter	Description
Noise Level	The level of background radio frequency energy. The lower the
	value and the wider the bar graph, the less background noise
	present.
	The trend graph to the right of the bar graph provides a visual
	interpretation of the level of background noise over time.
	Differences in background noise level are indicated by the
	following colors: green (low noise), yellow (middle of the range),
	and red (high noise).
	Range: –45 to –95 dBm
	Note	This parameter appears only if the Display in Percent
		check box is unchecked.
Signal Quality	The signal quality of the most recently received packets. The
	higher the value and the wider the bar graph, the clearer the signal.
	The trend graph to the right of bar graph provides a visual
	interpretation of the signal quality over time. Differences in signal
	quality are indicated by the following colors: green (highest
	quality), yellow (average), and red (lowest quality).
	Range: 0 to 100%
	Note	This parameter appears only if the Display in Percent
		check box is checked.
Beacons Received	The percentage of beacon packets received from the access point
	versus those expected to be received. The higher the value and the
	wider the bar graph, the clearer the signal.
	The trend graph to the right of bar graph provides a visual
	interpretation of the signal clarity over time. Differences in signal
	clarity are indicated by the following colors: green (highest
	quality), yellow (average), and red (lowest quality).
	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%
	Note	This parameter appears only if the Display in Percent
		check box is checked and the client adapter does not
		provide a signal quality value.
