Chapter 2: Installation

Link Planning

Before you install the airFiber AF-5, consider the following:

• Point-to-Point (PtP), daisy chain, or ring configuration

• Co-Location

Configuration

There are three typical configurations:

• PtP backhaul Uses two airFiber radios, one configured as Master and the other configured as Slave.

SlaveMaster

Point-to-Point Backhaul

• Daisy chain Uses multiple airFiber radios to extend the distance of a link, like a relay from point to point to point. The airFiber radios in the same node must use the same Wireless Mode (Master or Slave).

Daisy Chain Configuration

• Ring Uses multiple airFiber radios to form redundant paths. If one link goes down, the other links have an alternate route available. For each link, configure one airFiber radio as Master, and configure the other as Slave.

Co-Location

You can co-locate multiple airFiber radios if they are pointed in different directions. Co-located airFiber radios must use the same Wireless Mode (Master or Slave). Back-to-back airFiber radios can use the same frequency. We recommend that you use different frequencies for adjacent airFiber radios; however, this is not a strict requirement.

Installation Requirements

Pre-Assembly Tool

• 13 mm (½") wrench

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:

• At least 1 m (3.28 ft) below the highest point on the structure

• For tower installations, at least 3 m (9.84 ft) below the

top of thetower

• Ground wires – min. 10 AWG (5 mm2) and max. length:

1m(3.28ft). As a safety precaution, ground the airFiber

radios to grounded masts, poles, towers, or grounding bars.

WARNING: Failure to properly ground your

airFiber units will void your warranty.

Ring Configuration

Ubiquiti Networks, Inc.

• (Recommended) 2 Outdoor GigE PoE surge protectors

Note: For guidelines about grounding and

lightning protection, follow your local electrical regulatory codes.

Alignment

Tips

• To accurately align the airFiber radios for best

performance, you MUST align only one end of the link at a time.

• For more convenient alignment, you may consider using

long-range scopes (not included) temporarily attached to your airFiber radios.

• 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.

Determining the Received Signal Level

There are three methods for determining the received signal level:

• LED Displays (See the next column.)

• airFiber Configuration Interface (See “Using the airFiber Configuration Interface” on page 14.)

• Audio tone (Optional equipment required. See “Using

the Audio Tone” on page 16.)

Using the LED Displays

Before a link is established, the Master’s LED Display looks

likethis:

• GPS and Master LEDs are solidly lit

Note: The GPS LED may not be lit if there is a

weak GPS signal. A GPS signal is not required for alignment.

• Link Status LED flashes (Normal Flash 1:1)

• Remote and Local LED Displays show a double dash

ACT SPEED ACT SPEED

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. Ensure that the following bolts and nuts are loose:

• Four Pre-Installed M10x25 Flanged Bolts on the airFiber radio (two on each side)

• Four M10 Hex Nuts used to lock the elevation alignment on the Upper Mount Bracket (two on

eachside)

Ubiquiti Networks, Inc.

Chapter 2: InstallationairFiber® AF5/AF5U User Guide

2. Ensure that the pole mount is snug yet the four M10 Hex Nuts attaching the Pole Clamps are loose enough to allow rotation around the pole for azimuth alignment.

3. Master Visually aim the Master at the Slave. To adjust the Master’s position:

a. Rotate the airFiber radio on the pole to align the

azimuth.

b. Use the hex nut on the Elevation Rod to adjust the

elevation.

4. Slave Visually aim the Slave at the Master. To adjust the Slave’s position:

a. Rotate the airFiber radio on the pole to align the

azimuth.

b. Use the hex nut on the Elevation Rod to adjust the

elevation.

5. Check to see if a link is established. Ensure that the Link

Status LED is solidly lit green and the Remote and Local LED Displays of the Slave are displaying signal levels.

6. Slave Aim the Slave at the Master to achieve the strongest signal level on the Remote LED Display of the Slave.

Note: Values on the LED Displays are displayed in

negative (-) dBm. For example, 67 represents a received signal level of -67 dBm. Smaller numerical

values indicate stronger received signallevels. For

example, a reading of 49 is stronger than a reading of 55.

Note: Maximum signal strength can best be

achieved by iteratively sweeping through both azimuth and elevation.

7. Master Aim the Master at the Slave to achieve the strongest signal level on the Remote LED Display of the Master.

Note: If the Overload LED lights up, identify

and eliminate any source of strong in-band interference.

8. Repeat steps 6 and 7 until you achieve a symmetric link, with the signal levels within 1 dB of each other. This ensures the best possible data rate between the airFiber radios.

Note: Do NOT make simultaneous adjustments on

the Master and Slave.
