Building Elements - Avaya DECT R4 Installation And Administration Manual

Coverage in lifts might require base stations closer to or in the lift shaft.
●
Corners and irregularities in the construction such as partial renovation, extensions of
●
older buildings influence base station coverage.
Technical installations such as concentration of air-conditioning ducts might influence the
●
field pattern and therefore the coverage.

Building elements

Different building elements can affect coverage. For example:
The cell size depends on the material of the walls, ceilings, and floors.
●
Plain, light, or reinforced concrete, wood, and plaster differ in the way the materials absorb
●
and pass radio waves.
Metal walls and large metal cabinet rows reflect all signals, resulting in a greatly reduced
●
coverage in areas behind these objects. Radio signals cannot enter X-ray rooms in
hospitals that are protected by lead walls and computer rooms in buildings that are
protected against unwanted interference such as banks.
