Restrictions on Range
The following factors can restrict the radio signal range:
•
Hollow lightweight walls with foil-faced mineral wool
•
Suspended ceilings with metal or carbon fiber panels
•
Leaded glass or glass with metal coat
•
Steel furniture
•
Module mounted on metal wall
If a radio signal is sent at an angle through a wall, the angle of incidence also
influences the effective wall thickness and thereby, signal attenuation. Thus,
radio signals should not run through walls at too shallow an angle and wall niches
should be avoided.

Its maximum range must always be tested before commissioning.
