causes interference which reduces the capacity and coverage range of the base station.
Walls
Walls, ceilings, and floors have a significant impact on the coverage range. Different types of
walls have different impacts on the signal range. The following table lists the most common
types of walls and the approximate range achieved through these materials:
Type of wall
Stud wall
Concrete
Reinforced
concrete
Stone/brick
Metal
Wood
Wired glass
Surface coated
float glass
None
Note:
The values in this table are approximate only. The furniture in the coverage area

and the amount of movement also affect coverage range. For example, cranes in
a production hall. See
Ceilings and floors
The difference between ceilings and floors and walls is in the materials used. If concrete and
reinforced concrete are the main materials, determine the level of coverage of a base station on
the floor above and below. The coverage for concrete walls and ceilings extends to a radius of
approximately 15-20 metres providing coverage for the floors below and above. AIn some
cases, you can use an open stairwell or an atrium to provide coverage to two floors at the same
time. See Base station covering two floors
