operating in the same area. The frequencies shown on the

Frequency (MHz) selector are the carrier frequencies.

• Operation in the 4.9 GHz band must be enabled using a

Fluidmesh software plug-in. Refer to “Plug-In

management” (page 133) for details. Note that the 4.9 GHz

band is not available in Brazil and Canada.

5. If Advanced configuration mode was selected, choose the

required channel bandwidth from the Channel Width (MHz)

drop-down. Note that the radio units on both sides of a wireless

link must be set to the same channel width value. A channel

width mismatch will result in degraded communication between

the units.

CAUTION

Before finalizing the settings on the WIRELESS

RADIO window, refer to “Important considerations

for wireless settings” (page 65) below. This section

contains important information that may influence

your choice of wireless settings.

Important considerations for wireless settings

The following sub-sections contain important technical and regulatory

information that influences the settings on the WIRELESS

RADIO window.

• For information on the effects of network topology on frequency

selection, refer to “Point-to-Point and Point-to-Multipoint

considerations” (page 65).

• For information on how to avoid network co-location interference,

refer to “Co-location considerations” (page 66).

• For information on the effects of channel width on data rate and

throughput, refer to “Channel width considerations” (page 66).

• For information on using dynamic frequency selection to avoid

interference with terminal doppler weather radar, refer to “Dynamic

frequency selection considerations” (page 67).

Point-to-Point and Point-to-Multipoint considerations

If a Fluidmesh radio transceiver unit's FluidMAX Autoscan setting is

enabled, and the unit is assigned a Subordinate role within a point-to-

multipoint network topology:

• The Subordinate unit will mimic the frequency setting of the

principal unit that shares its cluster ID.

• The Subordinate unit's manual frequency selection setting will be

disabled by default.
