System Configuration
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 4-6) 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.
RSSI – The RSSI value for a selected port can be displayed and a representative
voltage output can be enabled.
• Output Activate: Enables or disables the RSSI voltage output on the external RSSI
connector. (Default: Enabled)
• Port Number: Selects a specific WDS port for which to set the maximum RSSI
output voltage level. Ports 1-16 are available for a Master unit, only port 1 for a
Slave unit. (Default: 1)
• Output Value: The maximum RSSI voltage level for the current selected WDS port.
A value of zero indicates that there is no received signal or that the WDS port is
disabled.
