Adjusting the Antenna
It is recommended to align the antenna to obtain the maximum SNR
value. The SNR (Signal/Noise Ratio) is a measure of the signal
quality, while RfRssi (Radio Frequency Received Signal Strength
Indicator) is a measure of the signal strength. Usually a higher SNR
will be coincident with a stronger signal, however, this may not be the
case when interference is present.
The SNR and RfRssi readings are available on the Telnet interface of
the subscriber station. Use the 'monitor' mode to provide a
dynamically updated display of the RSSI and other subscriber
statistics. From the root CLI mode, enter the following command to
activate the monitor display:
monitor <ENTER>
When monitor mode is active, the screen is updated continuously
with the latest subscriber statistics values. Hit any key to exit from
monitor mode.

Note: RfRssi values are negative, and an RfRssi of -35 dBm is
stronger than -50 dBm.
