APPLICATION INFORMATION
6.1
Transmission range
The main factors that influence the system transmission range are type and location of the
antennas of the receiver and the transmitter, type of terrain and degree of obstruction of
the link path, sources of interference affecting the receiver, and “dead” spots caused by
signal reflections from nearby conductive objects.
Since the expected transmission range strongly depends on this system conditions, range
tests should categorically be performed before notification of a particular range that will be
attainable by a certain application.
The following figures may be used as a rough guide only:
n
Line-of-sight connections: Typically 30 m (100 ft) range in corridors, up to 100 m (300
ft) in halls
n
Plasterboard walls / dry wood: Typically 30 m (100 ft) range, through max. 5 walls
n
Line-of-sight connections: Typically 30 m (100 ft) range in corridors, up to 100 m (300
ft) in halls
n
Ferro concrete walls / ceilings: Typically 10 m (30 ft) range, through max. 1 ceiling
n
Fire-safety walls, elevator shafts, staircases and supply areas should be considered as
screening.
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 avoid-
ed.
Other factors restricting transmission range:
n
Switch mounted on metal surfaces (up to 30% loss of transmission range)
n
Hollow lightweight walls filled with insulating wool on metal foil
n
False ceilings with panels of metal or carbon fibre
n
Lead glass or glass with metal coating, steel furniture
The distance between EnOcean receivers and other transmitting devices such as comput-
ers, audio and video equipment that also emit high-frequency signals should be at least 0.5
m (1.5 ft).
