33.070.20 - Paging systems

The present document applies to on-site and wide area paging equipment, operating in the frequency range of 25 MHz
to 470 MHz.
An on-site paging system is a privately owned and operated wireless communication system, used in a restricted and
predefined area, with the primary function to alert and/or inform ambulant people. The air interface of the system, using
a single radio channel, comprises at least one transmitter. The system may be extended to include a return, or talk-back
frequency. Mainly used for call acknowledgement, this frequency may also be used to supply some of the features of a
mobile radio service, or other two-way radio services, without the need to use a separate system.
Covering a larger geographical area, a wide-area system is typically associated with large organizations such as
emergency services and may include additional radio facilities and utilize different a frequency for return messaging,
which is outside the scope of the present document. These features should be tested against the relevant standard.
The present document specifies technical characteristics and methods of measurements for the following equipment
types:
1) base station transmitters and transcoders, with or without an external 50 Ω antenna connector;
2) base station receivers, with a permanent 50 Ω connector;
3) paging receiver, with or without an external 50 Ω antenna connector.
The existence of a Harmonised Standard does not imply the availability of the above frequency spectrum for the
particular types of equipment covered by the present document.
The present document covers the essential requirements of article 3.2 of Directive 2014/53/EU under the conditions
identified in annex A and contains requirements to demonstrate that "... Radio equipment shall be so constructed that it
both effectively uses and supports the efficient use of radio spectrum in order to avoid harmful interference" [i.1].
In addition to the present document, other ENs that specify technical requirements in respect of essential requirements
under other parts of article 3 of the Radio Equipment Directive [i.1] may apply to equipment within the scope of the
present document.

Covers the EMC requirements for ERMES paging receivers & ancillary equipment. The ETS may be used to demonstrate compliance with the requirements of the EMC Directive 89/336/EEC.

A private wide area paging system which provides the flexibility, versatility and speed of an on-site paging system but covering a wider area. Minimum performance characteristics and related methods of measurement for private wide-area paging systems. On-site paging systems with an extended free field range achieved by using a higher transmitter power and antenna location, as well as a specified receiver sensitivity. It may use time sharing in order to increase the number of virtually available channels. The time sharing proposed is a free running system that requires minimum overhead and supplies minimum loss of net-airtime. The system will work in the high band VHF or UHF frequency range. Types of equipment covered: base station transmitters/ receivers/ transceivers, pocket receivers. Potential customers include emergency services, hospitals and manufacturing industry that may be located at various sites within the coverage area. Additional standards/specifications may be required for equipment inteded to interface to the PSTN. This ETS, together with ETS 300 741, is intended to become a harmonised standard, the reference of which is intended to be cited in the Official Journal of the European Communities referencing the EMC Directive.
