Cisco Cisco Aironet 350 Wireless LAN Client Adapter

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

The actual reading could exceed the stated range.

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 the 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%

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 have been sent. The higher the value and 
the wider the bar graph, the clearer the signal.

The trend graph to the right of the 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%

This parameter appears only if the Display in percent 
check box is checked and the client adapter does not 
provide a signal quality value.
