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 these system conditions, range tests should categorically be per-
formed before notification of a particular range that will be attainable by a particular appli-
cation.
The following figures for expected transmission range are considered by using the PTM 100
radio transmitter module and the RCM 110 or RCM 120 radio receiver module with the pre-
installed whip antennas and may be used as a rough guide only:
•
10 m
in industrial applications with metal in the vicinity
•
30 m
for obstructed environment (e.g., through two brick walls inside a building)
•
300 m
for unobstructed environment (“free field”)
Further notes to determine the transmission range within buildings are available as down-
load from

Approval Requirements
The modules bear the EC conformity marking CE and conform to the R&TTE EU-directive on
radio equipment. The assembly conforms to the European and national requirements of
electromagnetic compatibility. The conformity has been proven and the corresponding do-
cumentation has been deposited at EnOcean. The modules can be operated without notifi-
cation and free of charge in the area of the European Union, in Switzerland, in Cyprus, in
Czech, in Estonia, in Hungary, in Latvia, in Lithuania, in Malta, in Poland, in Romania and in
Slovenia. The following provisos apply:
EnOcean RF modules must not be modified or used outside their specification
limits.
EnOcean RF modules may only be used to transfer digital or digitized data.
Analog speech and/or music are not permitted.
The final product incorporating EnOcean RF modules must itself meet the es-
sential requirement of the R&TTE Directive and a CE marking must be affixed
on the final product and on the sales packaging each. Operating instructions
containing a Declaration of Conformity has to be attached.
If transmitters are used according to the regulations of the 868.3 MHz band, a
so-called “Duty Cycle” of 1% per hour for each transmitter must not be ex-
ceeded (also see chapter 2.3.1).
