Output Power (EIRP) Defines the maximum average
transmit output power (in dBm) of the airFiber X radio.
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.
Note: The Antenna Gain and Cable Loss should be
configured before the Output Power . This is because
the range of the Output Power field is affected by
the Antenna Gain and Cable Loss values – changing
the antenna gain or cable loss adjusts the maximum
and minimum values you can select using the
Output Power slider. Since the Output Power
already includes the antenna gain and cable loss, it
represents EIRP; therefore, the value of
Output Power
is actually the total power the radio is transmitting
over the air. The current transmit power is displayed
by the
TX Power (EIRP) field on the Dashboard .
Note: The airFiber X radio may limit the output
power to a value less than the value specified
by this field, to comply with regulatory region
requirements. For a list of maximum output power
values by country and region, refer to
“Frequency
Ranges and Power Levels per Country/Region”
on page 4
5 .
Antenna Gain Enter the gain in dBi of the antenna that is
used in your installation. An improper value could cause
DFS false detections when operating on DFS frequencies.
Cable Loss Enter the cable loss in dB of the cable that is
used in your installation. An improper value could cause
DFS false detections when operating on DFS frequencies.
Receive Target Power To use the Automatic Transmit
Power Control (ATPC) feature, enable this option and enter
the desired power level that the receiver (on the far end of
the link) should see from this radio.
In ATPC, each airFiber X radio monitors the amount of
power received by the radio at the other end of the link.
If the reported value differs from the
Receive Target Power
value, the radio automatically adjusts its transmit output
power to match the
Receive Target Power value. The radio
will use its Output Power (EIRP) setting as the maximum
level at which it will transmit to maintain the Receive Target
Power .
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 X radio 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. The available
values depend on the
Radio Mode setting:
• If Radio Mode is set to MIMO :
• 10x (1024QAM MIMO)
• 8x (256QAM MIMO)
• 6x (64QAM MIMO)
• 4x (16QAM MIMO)
•
2x (QPSK MIMO)
• 1x (QPSK SISO)
• ¼x (QPSK SISO)
• If Radio Mode is set to SISO :
• 5x (1024QAM SISO)
•
4x (256QAM SISO)
• 3x (64QAM SISO)
• 2x (16QAM SISO)
• 1x (QPSK SISO)
• ¼x (QPSK SISO)
Automatic Rate Adaptation
Enabled by default, this
option allows the airFiber X radio to automatically adjust
the modulation rate to changing RF signal conditions.
Frequency Settings
The Valid Frequencies for your Country Code selection are
displayed. Ensure that you use frequencies that comply
with the local country regulations.
TX Frequency Enter a valid TX frequency. The current
state is displayed.
RX Frequency Enter a valid RX frequency. The current
state is displayed.
Wireless Security
airFiber uses 128‑bit, AES (Advanced Encryption Standard)
encryption at all times.
Key Type
Specifies the character format.
• HEX By default, this option uses hexadecimal
characters. 0‑9, A‑F, or a‑f are valid characters.
• ASCII ASCII uses the standard English alphabet and
numeric characters (0‑9, A‑Z, or a‑z).
