Installation Prerequisites
19
o Philips head screwdriver
o Flat-blade screwdriver
o A/F open ended spanner
Crimping tool for crimping RF cable to N-type connector (only relevant when implementing
external antenna)
Torque wrench for N-type connectors (only relevant when implementing external antenna)
Note: Airspan does not provide screws and wall anchors for mounting the ProST to the
wall. The screw size depends on the structure of the building to which the ProST is to be
attached. When selecting screw sizes, consideration must be given to the weight of the ProST
and load that may be induced in windy conditions.
Radio Site Planning
Proper site selection and planning before installing your ProST will ensure a successful deployment
of your AS.MAX system. Site planning includes the following main considerations:
Minimum obstructions (e.g. buildings) in the radio path between base station and the
ProST.
Mount radios as high as possible to avoid obstructions in the wireless path.
Check possibility of future obstructions such as plans to erect buildings and trees that may
grow tall enough to obstruct the wireless path.
Minimum incursions on Fresnel Zone (recommended minimum of 60% clearance of first
Fresnel Zone).
Align antenna for maximizing received signal strength (RSS).
Consider nearby sources of interference that could degrade performance of radio. Mount
radios as far from sources of interference as possible.
Ensure base station and ProST are within maximum coverage range of reception.
Maximum standard CAT-5 cable length connecting the outdoor ProST to the indoor SDA is
100 meters.
Minimal Radio Path Obstructions
AS.MAX radios communicate by propagation of waves. Thus, ensure minimum obstructions
(from, e.g. buildings and trees) in the radio path between base station and ProST. It is
essential that the radios or antennas be installed in such a way that their radio paths have a
clear path with each other.
Fresnel Zone Clearance
There must be sufficient open space around the radio path to minimize blocking of the radio
beam. A minimum of 60% of the first Fresnel Zone of the path should be clear of obstructions.
Despite a clear line-of-sight, objects close enough to the transmission path may cause
attenuation in signal strength and an increase in signal interference. Objects with reflective
surfaces that seem relatively far away, may still encroach on the Fresnel Zone, and cause
interference.
