Basic Wireless Settings
In this section, configure the basic wireless settings, such
as wireless mode, link name, country code, frequencies,
output power, speed, and gain.
Wireless Mode By default, the Wireless Mode is Slave. You
must configure one airFiber AF24 to Master because each
PtP link must have one Master.
Link Name Enter a name for your PtP link.
Country Code Each country has their own power level
and frequency regulations. To ensure the airFiber AF24
operates under the necessary regulatory compliance rules,
you must select the country where your device will be used.
The frequency settings and output power limits will
be tuned according to the regulations of the selected
country.

Change To select a new country, click Change.
Note: U.S. product versions are locked to the U.S.
Country Code to ensure compliance with FCC
regulations.
- Country Select the new country.
- I agree to these terms of use Check this box; you
must agree to the Terms of Use to use the product.
- Accept Saves your change.
- Cancel Discards your change.
Duplex Select Half Duplex or Full Duplex. Half-duplex
operation provides more frequency planning options at
the cost of higher latency and throughput. (Half-duplex
mode allows communication in one direction at a
time, alternating between transmission and reception.)
Full-duplex operation provides the highest throughput
and lowest latency; however, you have fewer frequency
management options. (Full-duplex mode allows
communication in both directions simultaneously.)
Note: For Half Duplex mode (default), the TX and RX
Frequencies on the same airFiber AF24 can be the
same or different to suit local interference. For Full
Duplex mode, the TX and RX Frequencies on the same
airFiber AF24 should be different.
TX Frequency Select a transmit frequency.
Note: The TX Frequency on the Master should be
used as the RX Frequency on the Slave, and vice
versa.
RX Frequency Select a receive frequency.
Output Power Defines the maximum average transmit
output power (in dBm) of the airFiber AF24. To specify the
output power, use the slider or manually enter the output
power value. The transmit power level maximum is limited
according to country regulations.
Maximum Modulation Rate or Modulation Rate Higher
modulations support greater throughput but generally
require stronger RF signals and a higher Signal-to-Noise
Ratio (SNR). By default, Automatic Rate Adaptation is
enabled, and Maximum Modulation Rate is displayed.
This allows the airFiber AF24 to automatically adjust the
modulation rate to changing RF signal conditions. Under
certain conditions, you may prefer to lock the Maximum
Modulation Rate to a lower setting to improve link
performance.
When Automatic Rate Adaptation is disabled, Modulation
Rate is displayed. Lock the Modulation Rate to the setting
of your choice.
Select one of the available modulation rates:
• 6x (64QAM MIMO)
• 4x (16QAM MIMO)
• 2x (QPSK MIMO)
• 1x (QPSK SISO)
• ¼x (QPSK SISO)
