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

Associated AP Status Parameter	Description
Signal to Noise Ratio	The difference between the signal strength and the noise level. The
	higher the value and the wider the bar graph, the better the client
	adapter’s ability to communicate with the access point.
	The trend graph to the right of the bar graph provides a visual
	interpretation of the signal-to-noise ratio over time. Differences in
	the client adapter’s ability to communicate are indicated by the
	following colors: green (highest quality), yellow (average), and
	red (lowest quality).
	Range: Poor, Fair, Good, Excellent; 0 to 50 dB
	Note	This parameter appears only if the Display in Percent
		check box is unchecked.
Overall Link Quality	A combination of signal strength and signal quality. The higher the
	value and the wider the bar graph, the better the client adapter’s
	ability to communicate with the access point.
	The trend graph to the right of the bar graph provides a visual
	interpretation of the overall link quality over time. Differences in
	quality are indicated by the following colors: green (highest
	quality), yellow (average), and red (lowest quality).
	Value: Poor, Fair, Good, Excellent; 0 to 100%
	Note	This parameter appears only if the Display as Percent
		check box is checked.
Link Speed	The site survey utility monitors transmitted network traffic, and
	the link speed reflects the current transmit rate of data packets.
	The trend graph provides a visual interpretation of the packet
	transmit rate over time. Differences in link speed are indicated by
	the following colors: green (fastest), yellow (middle of the range),
	and red (slowest).
	Value: 1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, or 54 Mbps,
		depending on radio band
