Understanding Architectural Impacts to Coverage

Construction materials and architectural features at the installation site can greatly impact base and
repeater coverage. In open or outdoor areas, the coverage radius of a base or repeater can be 150
meters or more. Indoors, the distance can drop to as low as 10 meters. In addition, the base mounting
height, nearby metal objects, and interference sources can impact coverage.
Wall Materials
This table shows coverage ranges for some typical wall materials:
Wall Material
Plaster walls over studs
Concrete
Heavily reinforced concrete
Stone/Brick
Metal
None
Multiple Floors
Many floor and ceiling materials allow coverage to extend to the floors above and below the base or
repeater floor. If that proves not to be the case, find areas where repeaters can link to the base or other
repeaters through stairwells or other openings in the building.
When planning multi-floor installations, it is helpful to think in three dimensions. Here is an example:
