2 Site Planning
2.1 General
Before the start of an installation a survey should be conducted of the proposed area of the site(s). The
survey personnel should be fully familiar with the details required to install the BridgeWave radio
system.
2.2 Equipment Checklist
The survey team will need at least the following equipment:
· Binoculars
· GPS Navigation Device
· Tape Measure
· Site Survey Report Form
· Level
2.3 Line of Sight (LOS)
BridgeWave Wireless links require line­of­sight for proper operation. Fortunately, the links are
relatively short and obstructions in the path can easily be identified. Binoculars can ease viewing in
poor light conditions.
The planning should include an investigation into future building plans that could block the LOS path,
and other long­term incremental obstructions such as trees. Intermittent obstructions such as aircraft at
a nearby airport should also be considered.
The following table details the minimum clearance needed from obstacles near the path in order to
ensure the radios will operate properly.
