Site Preparation and Precautions
Before installing the subscriber station and or antenna(s), it is important to plan the the complete installation and
make sure the appropriate safe guards are in place.
Site Selection
Consider the following recommendations when selecting an appropriate site for the subscriber station and
antenna(s):
• Mount the antenna(s) at the highest point possible. Reception will increase according to the height of the
antenna(s).
• Mount the antenna(s) in a place with as few obstructions as possible between the antenna(s) and the planned
service area.
• To avoid interference, mount the antenna(s) and subscriber station as far as possible from other antenna(s) and
subscriber stations.
• Keep the cable from the subscriber station to the antenna(s) as short as possible and mount the antenna(s) as
close as possible to the subscriber station. Using a cable longer than 2 m (6.6 ft) will result in greater loss and
more interference, as the cable will act as an antenna itself.
• Do not point the antenna(s) directly at populated areas.
• Locate the antenna(s) at least 3.6 m (11.8 ft) from people and public areas.
• Make sure the antenna(s) and subscriber station are easily accessible for maintenance purposes.
• Conduct a site survey to best position the subscriber station and antenna(s) in relation to other subscriber
stations, antennas and base stations in the area. The site survey should also take into consideration the overall
safety of the selected site
Site Survey
Most wireless networks include many subscriber/base stations installed in various locations in an overlapping
radio-cell pattern. It is important to position each subscriber station in an optimal location considering the
assignment of its radio channels. Therefore, a site survey becomes an essential first step before physically
deploying the subscriber station.
The site survey should include details important to the planning of the subscriber station deployment in each
specific site, including potential mounting points for the subscriber station and antennas, as well as the routing
options for data, power and antenna cables.
For safety, always consult with the local power utility as well. It is important to select a site that not only offers
maximum coverage, but is also safe for installers to work in.
