RSSI

The RSSI value displayed on the RSSI page represents a signal to noise ratio. A value of 30 would indicate that the power of the received signal is 30 dBm above the signal noise threshold. This value can be used to align antennas (see page 4-9) and monitor the quality of the received signal for bridge links. An RSSI value of about 30 or more indicates a strong enough signal to support the maximum data rate of 54 Mbps. Below a value of 30, the supported data rate would drop to lower rates. A value of 15 or less indicates that the signal is weak and the antennas may require realignment.

The RSSI controls allow the external connector to be disabled and the receive signal for each WDS port displayed.
