airFiber Configuration
The instructions in this section explain how to access
the airFiber Configuration Interface and configure the
following settings:
•
Wireless Mode
Configure one airFiber radio as the
Master
and the other as the
Slave
.
•
Duplex
The airFiber radio supports both half-duplex
and full-duplex operation. Half-duplex operation
provides more frequency planning options at the
cost of higher latency and throughput. Full-duplex
operation provides the highest throughput and
lowest latency; however, you have fewer frequency
management options.
-
Half Duplex (default)
The
TX
and
RX Frequencies
can
be the same or different to suit local interference.
