Chapter 5: Wireless Tab
The Wireless tab contains options to set up the wireless
part of the link. This includes wireless mode, link name,
frequencies, output power, speed, and wireless security.
Change To save or test your changes, click Change.
A new message appears. You have three options:
• Apply To immediately save your changes, click Apply.
• Test To try the changes without saving them, click Test.
To keep the changes, click Apply. If you do not click
Apply within 180 seconds (the countdown is displayed),
the airFiberX radio times out and resumes its earlier
configuration.
• Discard To cancel your changes, click Discard.
Write down the settings you configure on the Wireless tab.
You will need to enter the same settings on the airFiberX
radio at the other end of your PtP link. The exceptions are
as follows:
• Wireless Mode Configure one airFiberX radio as the
Master and the other as the Slave.
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 airFiberX radio as Master because
each PtP link must have one Master.
Link Name Enter a name for your PtP link. This name
must be the same on both Master and Slave radios in
order for them to connect.

Country Code Each country has its own power level
and frequency regulations. To ensure the airFiberX radio
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. For details, refer to this table, “Frequency Ranges
and Power Levels per Country/Region” on page 63.
This radio is restricted to use with a license and to use only in
certain EU countries or geographical areas of EU countries.
• 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.
Master TX Duty Cycle Use this to change the duty cycle
of the RF link (the Master’s TX percentage). Choose one of
the following values: 25%, 33%, 50%, 67%, or 75%.
Output Power (EIRP) Defines the maximum average
transmit output power (in dBm) of the airFiberX 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 setting on the Main tab.
Note: The airFiberX 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 49.
- 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.
Channel Bandwidth Select the appropriate channel size:
• AF-2X and AF-3X: 3.5, 5, 7, 10, 14, 20, 28, 30, 40, 50,
or 56 MHz
• AF-5X only: 5, 10, 20, 30, 40, or 50 MHz
Note:. The available channel bandwidths depend
on the regulatory requirements of the currently
selected country or region.
Frame Length (Available on AF-2X and AF-3X only.) Use
this to specify the frame length of the radio: default,
2.0ms, 2.5ms, 4.0ms, or 5ms. The frame length must be
the same on both Master and Slave radios. The default
value corresponds to 5ms for the 3.5MHz and 5MHz
bandwidths, or 2.0ms for all other bandwidths.
Note:. The AF-5X uses a frame length of 2.0ms (this
value cannot be changed).
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.
Note: If you are using the airFiber AF-5X radio with
an airFiber NxN Multiplexer, set the CableLoss to a
value that includes the additional cable loss due to
the Multiplexer. The additional cable loss (in dB) is:
• 4.1 for the AF-MPx4, or
• 7.2 for the AF-MPx8
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 airFiberX 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:
• 8x (256QAM MIMO)
• 6x (64QAM MIMO)
• 4x (16QAM MIMO)
• 2x (QPSK MIMO)
• 1x (½ Rate QPSK xRT)
• ¼x (¼ Rate QPSK xRT)
Frequency Settings
The Valid Frequencies for your Country Code selection are
displayed. Ensure that you use frequencies that comply
with the local country regulations.
TDD Split Frequency Mode This option lets you
configure separate frequencies for TX and RX. To configure
split frequencies, enable this option and select a different
RX frequency on each side of the link. This feature is useful
if both sides of the link do not have a common, clean
frequency. It is important for the RX frequency to be
clean; if different frequencies are clean on each end of the
link, select the clean RX frequency on each end.
Note for AF-5X only: Split frequency mode is not
available in DFS bands because the RX frequency
must match the TX frequency to allow the receiver
to scan for DFS on the TX frequency. In regions
where both DFS and non-DFS frequencies are
available, enabling split frequencies will disable any
DFS band frequencies. In regions where only DFS
frequencies are available, there will be no option to
turn on split frequencies.
Frequency Enter a valid frequency. The current state is
displayed.
Note: The Master and Slave should have the same
Frequency setting.
Wireless Security
airFiber uses 128-bit, AES (Advanced Encryption Standard)
encryption at all times.
AF-2X Split Frequency Settings
AF-3X Split Frequency Settings

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).
Key Select the format of the MAC address.
• HEX Enter 16bytes (eight, 16-bit HEX values). You can
omit zeroes and use colons, similar to the IPv6 format.
The default is:
0000:0000:0000:0000:0000:0000:0000:0000
Note: The airFiber Configuration Interface
supports IPv6 formats excluding dotted quad and
“::” (double-colon) notation.
• ASCII Enter a combination of alphanumeric characters.
Using 128-bit SHA1 (Secure Hash Algorithm 1), the
airFiberX radio hashes the ASCII key to create a 128-bit
key for AES.
