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.
Receiver
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.
