Important considerations for wireless settings
The following sub-sections contain important technical and regulatory
information that influences the settings on the
WIRELESS RADIO
window.

interference with terminal doppler weather radar, refer to
selection considerations” (page 70)
Co-location considerations
To avoid radio interference caused by unit co-location, set the frequencies
of co-located transceivers as far apart as practically possible.
Before a network is deployed, frequency allocations for every unit-to-unit
link must be planned in advance. A safe method is to use the narrowest
channel width that can realistically support the needed amount of data
throughput whilst separating the individual channels as much as possible.
Even if two radios are not transmitting on the same channel, their side lobes
may still cause them to interfere with each other. It is good practice to space
the radios as far apart as practically possible in the vertical plane, with
a minimum of 3ft/1m and an ideal distance of 5ft/1.5m between them.
Mounting radio transceiver units back-to-back or side by side may cause
co-location interference that will degrade performance across your network.
Channel width considerations
Whenever practically possible, setting the unit to operate at a narrower
channel width can help reduce overall network interference by increasing
the number of available channels.
The following table correlates different channel widths with their theoretical
maximum data rates and achievable throughput, assuming that the unit is
being used as part of a point-to-point configuration.
WARNING
Before changing the channel width value, make sure that the
overall frequency range you will be using is legal for your
territory. Changing the operating channel width may violate the
local
telecommunication authority’s regulations, lead to illegal
wireless operation, and have other harmful consequences.
