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.

NOTE
If a unit is configured as a Subordinate, you can still enable
manual frequency selection by disabling the Autoscan setting
on the ADVANCED RADIO SETTINGS page. Refer to
"Advanced radio settings" (page 88)
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.
IMPORTANT
The following table shows theoretical values under ideal
conditions. Actual throughput may vary depending on
environmental and other conditions.
