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
possible to force the rate selection algorithm to limit the modulation speed at a specific rate. This
option might be useful with unstable channel conditions.
Maximum TX Power: This setting controls the output power of the radio. By decreasing the
output power of a radio, you can decrease the overall E.I.R.P. By default, the radio transmission
power is controlled automatically by the innovative Fluidmesh Transmission Power Control
(TPC) algorithm. The Fluidmesh TPC algorithm tries to obtain an optimal link signal strength (about
-55 dBm) on both sides of the link while not exceeding the maximum TX power which can
be set by the user through the selector. Note that the maximum transmission power may vary
depending on the operating frequency channel of the radio.
