Installing the Subscriber Unit

• 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 unit are easily accessible for maintenance purposes.

• Conduct a site survey to best position the subscriber unit and antenna(s) in relation to other subscriber units,

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 unit 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 unit.

The site survey should include details important to the planning of the subscriber unit deployment in each specific

site, including potential mounting points for the subscriber unit 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.

Safety Precautions

When installing the subscriber unit or an antenna, make sure to adhere to the following safety precautions:

• Always install the subscriber unit with the help of a partner.

• Always use the most appropriate mounting method for the site and the equipment being installed. For

assistance, contact a Siemens representative.

• Always assume an overhead line can cause serious injury or death. Note that electric power lines and phone

lines look alike.

• Always wear the appropriate Personal Protective Equipment (PPE) for the task, including but not limited to

rubber boots, rubber gloves, hard hat, harness and lanyard, etc.

• Always use a ladder made of a non-conductive material, such as wood or fiberglass. Do not use a metal ladder.

• Always work under favorable conditions. Do not work on wet or windy days.

• If the subscriber unit or antenna begins to drop, step away immediately and allow it to fall. The subscriber unit,

cables, metal guy wires and pole (in the case of pole mount installations) are all excellent conductors. Any

contact between these components and an electrical power line will complete an electrical path through the

subscriber unit/antenna and the installer.

• If any part of the subscriber unit or an antenna comes in contact with an electrical power line, contact the local

power utility. Do not attempt to touch or remove the component.
