Please make sure the country has been properly specified before changing the frequency of the
system.
Frequency Selectors: All Fluidmesh units are equipped with multi-band radios capable of operating
on the 4.9-6 GHz bands
1
. You can change the frequency of each radio in order to minimize
interference with other wireless networks operating in the same area. The frequencies listed on
the Frequency Selector are the carrier frequencies. Please note that when the unit is forced to be
“SLAVE” of a point-to-multipoint topology, the frequency is NOT selectable. In fact, the SLAVE
will scan for the relative “MASTER” according to the configuration of the “MESH Cluster ID”
described in Section 7.8. The frequency selector in Mesh Point configured as slave will be available
by unchecking the autoscan box in advance radio settings page.
To avoid network co-location interference it is advised to have the frequencies as far apart as possible.
Before deploying your network, you need to plan you frequency allocation on every link. A good rule
of thumb is to use the narrowest possible channel that can support the amount of throughput needed
and separate the channels as much as possible. Although two radios are not on the same channel, they
can still interfere with one another because of the side lobes. It is also good practice to space the
radios vertically as far apart as possible with a minimum of 5ft 3ft., ideally 5ft. Mounting radios back
to back or side by side is not a good practice as it may lead to co-location interferences and will
strongly affect the performance of your network.

4.9 GHz must be enabled through the proper software plug-in. Please refer to Section 7.13 for details.
