DC Step code and later
-
Plasterboard walls / dry wood
Typically 30 m range, through max. 5 walls
-
Ferro concrete walls / ceilings
Typically 10 m range, through max. 1 ceiling
-
Fire-safety walls, elevator shafts, staircases and similar areas should be considered
as shielded
The angle at which the transmitted signal hits the wall is very important. The effective wall
thickness – and with it the signal attenuation – varies according to this angle. Signals
should be transmitted as directly as possible through the wall. Wall niches should be
avoided.
Other factors restricting transmission range include:
-
Switch mounting on metal surfaces (up to 30% loss of transmission range)
-
Hollow lightweight walls filled with insulating wool on metal foil
-
False ceilings with panels of metal or carbon fibre
-
Lead glass or glass with metal coating, steel furniture
The distance between EnOcean receivers and other transmitting devices such as computers,
audio and video equipment that also emit high-frequency signals should be at least 0.5 m.
