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.
