Testing for interference is important to establish the most stable link, thereby
ensuring the best possible throughput of the system. The Redline radio can be used
as a tool to determine whether interference is present on any of the prescribed
channels.
The radio on the remote end of the link can be temporarily disabled using the Web
GUI interface. This will ensure that no signals are received from the remote unit,
which would skew the results. Use the GUI to set the radio off and then click Test
button to activate this configuration. The remote unit will be disabled for five
minutes and then will reboot and resume normal transmission.
Use the GUI to reduce Tx power to –20 dBm and select channel 1 as a starting
point. Monitor the Receive Signal Strength - Mean and SINADR values. If no
interference is present, the RSSI should indicate –89.31 dBm and the SINADR
will read 0.00 dB.
When interference is present, the RSSI level will increase and the SINADR will
erratically display both positive and negative values. The greater the interference,
the higher the signal strength value will be. Repeat this procedure for the
remaining channels and record the results. This test should be repeated at the
remote location. These results will allow the installer select the channel having the
least interference at both sites.
