Fig. 2:
Radio transmission coverage
The values below are guideline values and may vary depending on local conditions:
Material / surface
Guideline values
Direct (visual) connection
Approx. 100%
Walls, ceilings and similar obstacles reduce the radio transmission coverage.
The following approximate values can be expected:
Material / surface
Guideline values
Wood, plaster, uncoated glass
70 … 100 %
Bricks, chipboard
65 … 95 %
Reinforced concrete
10 … 90 %
Metal, aluminium lamination
0 … 10 %
Fire walls, lift wells, staircases and supply areas are considered as separating walls, just like the installation of
the receiver in metal housings.
The distance between the transmitter and the receiver and from other transmitters that also emit high-frequency
signals (e.g. computers, audio and video systems) should be 1.0 m minimum.
