¾ Wall Mounting:
• drill bits
• 4 x wall anchors
• 4 x screws
• Philips head screwdriver
• Flat-blade screwdriver
• A/F open ended spanner
¾ Crimping tool for crimping RF cable to N-type connector (only relevant when
implementing external antenna).
¾ 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.
3.4 Radio Site Planning
Proper site selection and planning before installing your ProST will ensure a successful
deployment of your Airspan WiMAX system. Site planning includes the following main
considerations:
¾ Minimum obstructions (e.g. buildings) in the radio path between base station and the
ProST.
¾ Mount radios as high as possible to avoid obstructions in the wireless path.
¾ Check possibility of future obstructions such as plans to erect buildings and trees that
may grow tall enough to obstruct the wireless path.
¾ Align antenna for maximizing received signal strength (RSS).
¾ Consider nearby sources of interference that could degrade performance of radio. Mount
radios as far from sources of interference as possible.
¾ Ensure base station and ProST are within maximum coverage range of reception.
¾ Maximum standard CAT-5e cable length connecting the outdoor ProST to the indoor SDA
is 100 meters.
3.4.1 Minimal Radio Path Obstructions
Airspan WiMAX 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.
3.4.2 Fresnel Zone Clearance
It is advisable to have a 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.
