PTM 210 / PTM 210C 

 
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 for expected transmission range are considered by using a PTM, a 

STM or a TCM radio transmitter device and the TCM radio receiver device with preinstalled 

whip antenna and may be used as a rough guide only: 

 

Line-of-sight connections: Typically 30 m range in corridors, up to 100 m in halls 

Plasterboard walls / dry wood: Typically 30 m range, through max. 5 walls 

Line-of-sight connections: Typically 30 m range in corridors, up to 100 m in halls 

Ferro concrete walls / ceilings: Typically 10 m range, through max. 1 ceiling 

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 

avoided. Other factors restricting transmission range: 
Switch mounted 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 com-

puters, audio and video equipment that also emit high-frequency signals should be at least 

0.5 m
