Package Contents

* Comes with (1) Low-Band or (1) High-Band Duplexer pre-installed for SISO mode. For MIMO mode, a second Duplexer is available, model AF-11-DUP-L or AF-11-DUP-H.

Installation Requirements

• Clear line of sight between airFiber radios
• Vertical mounting orientation
• Mounting point:
  • At least 1 m below the highest point on the structure
  • For tower installations, at least 3 m below the top of the tower
• Ground wires – min. 10 AWG (5 mm2) and max. length: 1 m. As a safety precaution, ground the airFiber radio to grounded masts, poles, towers, or grounding bars.

  	WARNING: Failure to properly ground your airFiber radio will void your warranty.

• (Optional) MIMO mode: A second Duplexer of the same band type: Low-Band Duplexer (model AF-11-DUP-L) or High-Band Duplexer (model AF-11-DUP-H):

  	Note: The AF-11 radio has one Duplexer pre-installed for SISO mode. For MIMO mode, a second Duplexer must be purchased separately. The Duplexer(s) must match the terms of your license (frequency bands and polarities allowed).

• (Optional) If not using PoE: DC power source and 12/30 AWG power cable
• Outdoor, shielded Category 6 (or above) cabling and shielded RJ-45 connectors are required for all wired Ethernet connections.
• (Recommended) Surge protection should be used for all outdoor installations. We recommend that you use two Ethernet Surge Protectors, model ETH-SP-G2, one within one meter of the device and the other at the entry point to the building. The ETH-SP-G2 will absorb power surges and safely discharge them into the ground.

  	Note: For guidelines about grounding and lightning protection, follow your local electrical regulatory codes.

Hardware Overview

Low-Band Duplexer	High-Band Duplexer

Chain 0 / Chain 1
When the Chain 0 or Chain 1 duplexer is installed, its N-type connector is located here, allowing connection to an RF cable (Chain 1 is covered by the removable Duplexer Cap).
Signal LEDs
Signal 4 LED will light blue when on. Signal 3 LED will light green when on. Signal 2 LED will light yellow when on. Signal 1 LED will light red when on. Bootup to airOS When powering on, the Power, MIMO, LINK, and Signal 1-4 LEDs light on. Once the CPU code takes over, the MIMO, LINK, and Signal 1-3 LEDs turn off. Signal 4 LED remains lit to indicate the boot sequence is underway. Initializing airFiber Software When the airFiber application begins to boot under airOS, the Signal 4 LED goes from solidly on to a 2.5 Hz flash. This continues until the device is fully booted. Signal Level Once fully booted, the Signal 1-4 LEDs act as a bar graph showing how close the device is to ideal aiming. This is auto-scaled based on the link range, the antenna gains, and the configured TX power of the remote device. Each Signal LED has three possible states: On, Flashing, and Off. All Signal LEDs would be solidly on in an ideal link. For example, if the link has a 1 dB loss, the Signal 4 LED will flash; a 2 dB loss and the Signal 4 LED will turn off. The full bar graph LED states are shown below. dB loss 0 -1 -2 -3 -4 -5 -6 -7 -8 -9 -10 -11 -12 -13

Installation Overview

We recommend that you configure your paired radios before site installation.

• Install the Duplexer(s) in the radio.
• Connect the airFiber Gigabit PoE adapter to the DATA port, and connect your computer to the MGMT port.
• Configure the radio.
• Install a ground wire and mount the radio on the airFiber AF-11G35 antenna (or a compatible antenna).
• At the installation site, install the antenna with the mounted radio (see the antenna’s Quick Start Guide for installation instructions).
• Connect the DATA port to your LAN, and connect power (PoE or DC power) to the radio.
• Establish and optimize the RF link.

Installing the Duplexers

SISO Mode Installation

Each AF-11 radio already contains one Low-Band Duplexer or one High-Band Duplexer for SISO mode. However, before you install the radios, you must ensure that Duplexers in the paired radios are positioned in the reverse order from each other.

	Note: For example, if the numbers on the first radio’s Duplexer are (left to right) 1/3, then the numbers on the second radio’s Duplexer should be 3/1.

Radio 1	Radio 2

Ensure that the Duplexers in your paired radios are installed in this manner. For instructions on how to access the Duplexers and remove or install them, see “MIMO Mode Installation”.

MIMO Mode Installation

	Note: MIMO operation requires two licenses, one per polarization, and two Duplexers of the same band type.

1. 

2. 

	Note: Position the low channel and high channel ports to yield the required transmit and receive frequencies. Also, ensure that the numbers on the right-side Duplexer are in the reverse order of the numbers on the left-side Duplexer.

3. 

	WARNING: Tighten the collars alternately, a half turn at a time, until both are fully tightened. Failure to do so may result in damage to the Duplexer.

4. 

5. 

6. Repeat steps 1-5 for the other radio in the link, ensuring that the numbers on the second radio’s Duplexers are in the reverse order of the numbers on the first radio’s Duplexers.

	Note: For example, if the numbers on the first radio’s Duplexers are (left to right) 2/4 and 4/2, the numbers on the second radio’s Duplexers should be 4/2 and 2/4.

3. If you are using DC power, connect the other end of the Ethernet cable to your LAN.

Connecting Power

Follow the instructions for the source of power that you are using:

• “Power Over Ethernet”
• “DC Power”

Power Over Ethernet

	WARNING: Use only the included adapter, model POE-50-60W. Failure to do so can damage the unit and void the product warranty.

DC Power

1. Connect a DC power cable to the Terminal Block. (The +VDC and GND can be connected to either terminal.)

   

2. Connect the other end of the DC power cable to a DC power supply that supplies +50VDC.

	WARNING: Applying a negative voltage such as -48VDC will damage the radio.

3. Connect the DC power supply to its source.

Alignment

Tips

• To accurately align the airFiber radios for best performance, you MUST align only one end of the link at a time.
• You may need to use additional hardware to compensate for issues such as the improper orientation of a mounting pole or significant elevation differences between airFiber radios.

Establishing a Link

Adjust the positions of the Master and the Slave to establish a link. The following section features the airFiber X antenna, AF-11G35:

	Note: The Master must be aimed first at the Slave because the Slave does not transmit any RF signal until it detects transmissions from the Master.

1. Master Visually aim the Master at the Slave. To adjust the Master’s position, adjust the azimuth and the elevation.

   Adjust the azimuth:

   1. Loosen the four flange nuts on the two pole clamps.
   2. Rotate the antenna to point towards the other end of the link.
   3. Tighten the four flange nuts on the two pole clamps.

   

   Adjust the elevation angle:

   1. Loosen the eight hex head bolts so that the washers can spin freely by hand.
   2. Tighten or loosen the Elevation Adjustment Bolt to set the desired tilt.
   3. Tighten the eight hex head bolts.

   

	Note: Do NOT make simultaneous adjustments on the Master and Slave.

2. Slave Visually aim the Slave at the Master. To adjust the Slave’s position, adjust the azimuth and elevation as described in step 1.
3. Check to see if a link is established. Ensure that the LINK LED is solidly lit green and the Signal LEDs of the Slave are displaying signal levels.

   

4. Slave Aim the Slave at the Master to achieve the strongest signal level on the Master.

   	Note: Refer to the Signal LEDs section for details on the signal values.

   	Note: Maximum signal strength can best be achieved by iteratively sweeping through both azimuth and elevation.

5. Master Aim the Master at the Slave to achieve the strongest signal level on the Slave.
6. Repeat steps 4 and 5 until you achieve an optimal link, with all four Signal LEDs solidly lit. This ensures the best possible data rate between the airFiber radios.
7. Lock the alignment on both airFiber antennas by tightening all the nuts and bolts.
8. Observe the Signal LEDs of each airFiber radio to ensure that the values remain constant while tightening the nuts and bolts. If any LED value changes during the locking process, loosen the nuts and bolts, finalize the alignment of each airFiber antenna again, and retighten the nuts and bolts.
