Foreword
This European Telecommunication Standard (ETS) has been prepared by the Radio Equipment and
Systems (RES) Technical Committee of the European Telecommunications Standards Institute (ETSI).
This ETS is based mainly on CEPT Recommendation T/R 20-05 and ESPA publications 4.2.6 and 4.2.6.a.
In this ETS the operational aspects of the on-site paging service have been included.
In preparing this ETS, much attention has been given to assure a low interference probability, while at the
same time allowing a maximum flexibility and service to the end-user.
This ETS does not include performance characteristics that may be required by the user or requirements
for interfacing equipment.
The conditions for licensing as well as conditions for interfacing to PSTN are determined by the appropriate
authorities.
Every ETS prepared by ETSI is a voluntary standard. This ETS contains text concerning type approval of
the equipment to which it relates. This text should be considered only as guidance and does not make this
ETS mandatory in its status as a standard. However, this ETS can be referenced, wholly or in part, for
mandatory application by decisions of regulatory bodies.

1 Scope
This ETS specifies the minimum performance characteristic and the related methods of measurement for
on-site paging transmitters and receivers. Although this ETS covers the general operational aspects of on-
site paging systems, it is restricted to the wireless (radio and loop) communications of the service. It is
assumed that the radio type of system will operate in the frequency range of 25 MHz to 470 MHz, and loop
systems below 150 kHz.
This ETS does not cover radiation below 25 MHz, except for the output of loop equipment.
Additional standards or specifications may be required for equipment intended to interface to the Public
Switched Telephone Network (PSTN).
This ETS may be used by accredited test laboratories for type testing of the equipment.
This ETS also contains instructions for the presentation of equipment for type testing purposes.
The types of equipment covered by this ETS are as follows:
- base station transmitters (radio and loop), with or without an external 50 W antenna connector;
- base station receivers, with a permanent 50 W connector;
- pocket unit (receiver, transceiver or transmitter), with or without an external 50 W antenna
connector.
Annex A: provides information concerning test sites and general arrangements for measurements
involving the use of radiated fields.
Annex B: provides information concerning the on-site paging service.
Annex C: provides normative information concerning measuring support for pocket equipment.
Annex D: contains normative specifications for adjacent channel power measuring receiver.
Annex E: is a graphic representation of the normative subclause 10.4.1.3 referring to the limits for
spurious radiations of loop receivers.
Annex F: contains a list of informative references.
2 Normative references
This ETS incorporates by dated or undated reference, provisions from other publications. These normative
references are cited at the appropriate places in the text and publications are listed hereafter. For dated
references, subsequent amendments to or revisions of any of these publications apply to this ETS only
when incorporated in it by amendment or revision. For undated references the latest edition of the
publication referred to applies.
