Pole-Mounting Tool
17 mm wrench
Other Requirements
Clear line of sight between airFiber radios
Clear view of the sky for proper GPS operation
Vertical mounting orientation
Mounting location with < 0.5° displacement due to twist and sway under wind loading
Mounting point:

Note: For guidelines about grounding and lightning protection, follow your local
electrical regulatory codes.
Outdoor, shielded Category 6 (or above) cabling and shielded RJ45 connectors are
required for all wired Ethernet connections.
Installation Overview
We recommend that you configure your paired airFiber radios before mounting. Below is an
overview of the installation with specific details in the following instructions:
Connect Power over Ethernet to the Data port, and connect an Ethernet cable between
your computer and the Management port.
Configure the device settings in the airFiber Configuration Interface.
Once configuration is complete, disconnect the cables to move the airFiber radios.
Pre-assemble the mounting hardware.
Install the airFiber radios at the site.
Establish and optimize the RF link.
Note: The AF-5 and AF-5U models share the same installation and configuration
instructions.

airFiber Configuration
This section explains 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.
Full Duplex The TX and RX Frequencies should be different.
TX and RX Frequencies The TX Frequency on the Master must match the RX Frequency on

the Slave, and vice versa.
1. Connect an Ethernet cable from your computer to the Management port on the airFiber
radio.
2. Configure the Ethernet adapter on your computer with a static IP address on the
192.168.1.x subnet.
3. Launch your web browser. Type http://192.168.1.20 in the address field and press enter
(PC) or return (Mac).
4. The login screen will appear. Enter ubnt in the Username and Password fields. Select
your Country and Language. You must agree to the Terms of Use to use the product.
Click Login.

5. The Main tab will appear. Click the Tools drop-down and select Link Calculator. This tool
will guide you on how to best minimize bandwidth and power/interference issues.
6. Enter the requirements of your link, and then click Calculate. Adjust the values as
needed to get the optimal result, and then write down the settings needed for your
configuration.
7. Click the Wireless tab.
Note: U.S. product versions are locked to the U.S. Country Code to ensure
compliance with FCC regulations.
Note: If you do not see the Link Calculator, upgrade the firmware on your
airFiber radios. Download the firmware at: ui.com/download/airfiber

8. Enter the Basic Wireless Settings:
a. For one airFiber radio, select Master as the Wireless Mode. For the other airFiber
radio, keep the default, Slave.
b. Enter a name in the Link Name field. This should be the same on both the Master and
the Slave.
c. For the Duplex drop-down:
Half Duplex The default mode. The TX and RX Frequencies can be the same or
different to suit local interference.
Full Duplex The TX and RX Frequencies should be different.
d. Select a TX Frequency. This must match the RX Frequency on your other airFiber
radio.
e. Select a RX Frequency. This must match the TX Frequency of your other airFiber
radio.
f. If needed, change the Output Power and/or Maximum Modulation Rate settings.
9. Configure the Wireless Security:
a. Select the AES Key Type, HEX or ASCII.
b. For the Key field:
HEX Enter 16 bytes (eight, 16-bit HEX values: 0-9, A-F, or a-f). You can omit zeroes and
use colons, similar to the IPv6 format.
ASCII Enter a combination of alphanumeric characters (0-9, A-Z, or a-z).
10. Click Change and then click Apply.
11. In-Band Management is enabled by default, so each airFiber radio must have a unique
Note: The airFiber Configuration Interface supports IPv6 formats excluding
dotted quad and "::" (double-colon) notation.
