Another approach is to use a bandpass filter to attenuate all signals outside the desired band.
▪ Multiple AP radios can co-exist in proximity to each other with only very minor
interference. Each network address has a different hop pattern. Additional isolation can be
achieved by using separate directional antennas with as much vertical or horizontal
separation as is practical.
▪ If constant interference is present in a particular frequency zone, it may be necessary to
“skip” that zone from the hopping pattern. The radio includes built-in software to help you
identify and remove blocked frequency zones from its hopping pattern. See Skip Zones
Menu
for more information.
▪ If interference problems persist even after skipping some zones, try reducing the length of
data streams. Groups of short data streams have a better chance of getting through in the
presence of interference than do long streams.
▪ The power output of all radios in a system should be set for the lowest level necessary for
reliable communications. This lessens the chance of causing unnecessary interference to
nearby systems.
