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.

• TX and RX Frequencies The TX Frequency on the
Master must match the RX Frequency on the Slave, and
vice versa.
