Frequency Configuration
FDD will be most useful in situations that have plenty of
spectrum available and will show the greatest benefit on
shorter-range links. For optimal performance, you should plan
out channel pairs that have maximum frequency separation.
Since the AF5 uses sophisticated data processing algorithms
and a special antenna structure to eliminate the need for a
pre-configured duplexing filter, you should space the 2 duplex
channels at either end of the spectrum near the band edges
for maximum-range applications.
Generally speaking, you can configure shorter-range links
for less channel separation between uplink and downlink.
You should also use the narrowest channel bandwidth that
supports the intended link capacity. This conserves valuable
frequency resources and also maximizes link budgets.

is currently developing a configuration tool,
the airFiber5 Link Calculator*, that will guide you on how to
best minimize bandwidth and power/interference based on
the specific requirements of your installation.
* The airFiber5 Link Calculator will be available as a new tool in an upcoming firmware update. Check
for firmware announcements.
