A radio signal's strength decreases with distance as it is sent in all directions. In
addition, other factors influence the radio signal strength.
Below are a few examples of interference and attenuating impact of different
materials.

Avoid under all circumstances to metallically
screen a room device.
Building materials as well as wall angles in particular influence the radio signal
range with the radio link. The greater the angle at which electromagnetic waves hit
a wall, the greater signal attenuation.
As a result, avoid flat angles and wall niches.
