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 base 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 base
station.
The site survey should include details important to the planning of the base station deployment in each specific
site, including potential mounting points for the device 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 base station or an antenna, make sure to adhere to the following safety precautions:
• Always install the base station 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 base station or antenna begins to drop, step away immediately and allow it to fall. The base station,
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
base station/antenna and the installer.
• If any part of the base station 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.
Section 2.5
Installing the Base Station in Hazardous Locations
The RUGGEDCOM WIN7235 is designed to comply with the safety standards for Class I, Division 2, Zone 2
hazardous locations where concentrations of flammable gases, vapors or liquids may be present, as opposed to
normal operating environments.
Special Conditions for Safe Use
Installation and use of the device in a hazardous location must meet the following special conditions for safe use:
• Substitution of components may impair suitability for Class I, Division 2
• Do not disconnect equipment unless power has been switched off or the area is known to be non-hazardous
• Use only a Lambda DPP50-48 Power Supply in conjunction with the device
