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 the DFS is required by law in many
countries and by disabling it you might incur fines and criminal charges by the local
telecommunication authorities.
IN NO EVENT SHALL FLUIDMESH NETWORKS, INC. BE LIABLE FOR ANY
INCIDENTAL, CONSEQUENTIAL OR SPECIAL DAMAGES, WHETHER BASED ON
TORT, CONTRACT, OR OTHERWISE, ARISING OUT OF OR IN CONNECTION WITH
IMPROPER USE OR OPERATION OF THE DFS FUNCTIONALITIES.

Table 7.2: FluidMAX Management Options
7.8 Advanced Wireless Settings
The advanced wireless settings menu (Figure 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 fact, the network administrator will only have to
change the frequency of the Master unit to force all the slaves to scan the air and reconnect to the
Master with the same Mesh Cluster ID. Please make sure that different point-to-multipoint cluster
have different Mesh Cluster IDs or they will be conflicting on the slave perspective leading to
unpredictable network topologies.
Transmission Rate Selection: Each FM unit implements a proprietary data-rate selection
algorithm which is able to adapt to the specific radio channel conditions. Through this setting, it is
