*Check for any reported alarm messages in the Event Log
The best way to discover if there is a source of interference is to use the spectrum
analyzer. By turning the antenna 360 degrees, you can find out which direction is the
interference coming from. it will also show the frequencies and the level of signal is
Detected.
When a source of interference is identified and when the level and frequencies are
known, the next step is to avoid the interference. Some of the following actions can be
Tried:
*Change the RF channel to the one away from the interference source.
*Change the polarization of the antenna; try to change to a polarization different
from the interferer.
*A small beam antenna may helps. (Such as some grid or dish antenna, align
The antenna in to the particular direction will reduce the affects from the
interference source) This solution cannot help when the source of interference
is right behind the remote site.
Before checking for interference, ensure all the hardware works well and
configurations are correct. The path analysis, cabling and antennas should be
checked as well.
