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 .
Slave Master
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 .
Ring Configuration
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 (
11/16
") 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 mm
2
) 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.
• (Recommended) 2 Outdoor GigE PoE surge protectors
Note: For guidelines about grounding and
lightning protection, follow your local electrical
regulatory codes.
• Outdoor, shielded Category 6 (or above) cabling and
shielded RJ-45 connectors are required for all wired
Ethernet connections.
