Follow the instructions on the pages indicated to perform these functions.
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
