interference in the network and to increase the number of available channels. Please remember to
set the same channel width on both sides of the wireless link. A channel width mismatch will
prevent the FM units from communicating properly. Please note that changing the channel width
may violate the local telecommunication authority’s guidelines and lead to illegal wireless operations.

DFS Management: Each device implements a proprietary distributed channel switching algorithm
which is used when radar is detected to comply with the Dynamic Frequency Selection (DFS)
international regulations. Upon radar detection, two communicating Fluidmesh units agree to switch
to the next radar-free channel so that they can continue to communicate on that channel. The DFS
is automatically enabled in the following frequency ranges: 5.250 GHz – 5.350 GHz and 5.470
GHz – 5.725 GHz. The DFS management can be manually disabled. The number of detected radars
is reported as well. Outside these mandatory frequency bands, the DFS is not required and it is
disabled by default. Please note law in many countries requires the DFS and by disabling it you
might incur fines and criminal charges by the local telecommunication authorities.

7.8 Advanced Wireless Settings
The advanced wireless settings menu (Fig. 7.7) can be used to configure the following advanced
wireless parameters:
FluidMAX Management: Although the FluidMAX engine automatically selects the most appropriate
MAC protocol to be used according to the detected network topology, convenient selectors are
included in the FMQuadro to force the FluidMAX operations and control the FluidMAX role of
the unit. Please refer to Table 7.2 for the available options and their specification. When the units
are set to be Master or Slave, an additional setting must be specified: “Mesh Cluster ID”. The Mesh
Cluster ID is used to associate the specific slave with a Master. Once the Mesh Cluster ID is set,
the slaves will scan the frequencies searching for the correspondent Master unit. This feature can
be extremely useful during network planning and testing in dense point-to-multipoint networks. In
