Mounting radio transceiver units back-to-back or side by side may cause
co-location interference that will degrade performance across your
network.
Channel width considerations
Whenever practically possible, setting the unit to operate at a narrower
channel width can help reduce overall network interference by increasing
the number of available channels.
WARNING
Before changing the channel width value, make sure that the
overall frequency range you will be using is legal for your
territory. Changing the operating channel width may violate the
local telecommunication authority’s regulations, lead to illegal
wireless operation, and have other harmful consequences.
The following table correlates different channel widths with their
theoretical maximum data rates and achievable throughput, assuming that
the unit is being used as part of a point-to-point configuration.
IMPORTANT
The following table shows theoretical values under ideal
conditions. Actual throughput may vary depending on
environmental and other conditions.
The Cisco FM Ponte kit is limited to a theoretical maximum of
50 Mbps usable Ethernet throughput (under optimal wireless
link conditions).

7.4.3. Antenna-alignment tools and physical statistics
The
ANTENNA ALIGNMENT AND STATS
window contains controls to
monitor current and average radio link status during operation of the unit,
allowing you to easily adjust the alignment of the unit's antennas.
The window shows a list of wireless links to other Fluidmesh units that
have been detected by the local unit, and the relative strength of each
wireless link in decibel-milliwatts (dBm).
