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.

This European Telecommunication Standard (ETS) has been produced by the Radio Equipment and
Systems (RES) Technical Committee of the European Telecommunications Standards Institute (ETSI).
This ETS consists of two parts as follows:
Part 1: "Technical characteristics for private wide-area paging systems";
Part 2: "Functional characteristics and access protocol for private wide-area paging systems on
shared channels".
This ETS has been produced by ETSI in response to a mandate from the European Commission issued
under Council Directive 83/189/EEC (as amended) laying down a procedure for the provision of
information in the field of technical standards and regulations.
This ETS, together with ETS 300 741, is intended to become a Harmonized Standard, the reference of
which will be published in the Official Journal of the European Communities referencing the Council
Directive on the approximation of the laws of the Member States relating to electromagnetic compatibility
("the EMC Directive") (89/336/EEC as amended).
Technical specifications relevant to the EMC Directive are given in annex E.
This ETS includes the following annexes:
- annex A is normative and specifies requirements concerning test sites and general arrangements
for measurements involving the use of radiated fields;
- annex B is normative and specifies requirements for a simulated human body for measurements on
pocket receivers;
- annex C is normative and specifies an adjacent channel power measuring receiver;
- annex D is normative and specifies the calculations of spurious response frequencies;
- annex E is normative and specifies the technical requirements relevant for compliance with the
essential requirements the EMC Directive;
- annex F is informative and describes basic system services;

Introduction
Private Wide-Area Paging (PWAP) systems are basically On-Site Paging (OSP) systems with an
extended range achieved by using a higher transmitter power (for guidance 25W could be a suitable
value) and antenna location, as well as a specified receiver sensitivity. These systems can use time
sharing in order to increase the number of virtual available channels. The time sharing as specified in
part 2 of this ETS is a free running system that requires minimum overhead and supplies minimum loss of
net-air time.
Potential applications include emergency services, hospitals and manufacturing industry that may be
located at various sites within the covered area.
This ETS is based mainly on ETS 300 224, ETS 300 133 part 5, ESPA publication 4.2.7.
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.
The conditions for licensing as well as conditions for interfacing to the Public Switched Telephone Network
(PSTN) are determined by the appropriate authorities.
Additional standards or specifications may be required for equipment intended to interface to the Public
Switched Telephone Network.

Foreword
This European Telecommunication Standard (ETS) has been produced by the Radio Equipment and
Systems (RES) Technical Committee of the European Telecommunications Standards Institute (ETSI).
This ETS consists of two parts as follows:
Part 1: "Technical characteristics for private wide-area paging systems";
Part 2: "Functional characteristics and access protocol for private wide-area paging systems on
shared channels".
This ETS has been produced by ETSI in response to a mandate from the European Commission issued
under Council Directive 83/189/EEC (as amended) laying down a procedure for the provision of
information in the field of technical standards and regulations.
This ETS, together with ETS 300 741, is intended to become a Harmonized Standard, the reference of
which will be published in the Official Journal of the European Communities referencing the Council
Directive on the approximation of the laws of the Member States relating to electromagnetic compatibility
("the EMC Directive") (89/336/EEC as amended).
Technical specifications relevant to the EMC Directive are given in annex E.
This ETS includes the following annexes:
- annex A is normative and specifies requirements concerning test sites and general arrangements
for measurements involving the use of radiated fields;
- annex B is normative and specifies requirements for a simulated human body for measurements on
pocket receivers;
- annex C is normative and specifies an adjacent channel power measuring receiver;
- annex D is normative and specifies the calculations of spurious response frequencies;
- annex E is normative and specifies the technical requirements relevant for compliance with the
essential requirements the EMC Directive;
- annex F is informative and describes basic system services;
- annex G is informative and contains a bibliography.

Introduction
Private Wide-Area Paging (PWAP) systems are basically On-Site Paging (OSP) systems with an
extended range achieved by using a higher transmitter power (for guidance 25W could be a suitable
value) and antenna location, as well as a specified receiver sensitivity. These systems can use time
sharing in order to increase the number of virtual available channels. The time sharing as specified in
part 2 of this ETS is a free running system that requires minimum overhead and supplies minimum loss of
net-air time.
Potential applications include emergency services, hospitals and manufacturing industry that may be
located at various sites within the covered area.
This ETS is based mainly on ETS 300 224, ETS 300 133 part 5, ESPA publication 4.2.7.
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.
The conditions for licensing as well as conditions for interfacing to the Public Switched Telephone Network
(PSTN) are determined by the appropriate authorities.
Additional standards or specifications may be required for equipment intended to interface to the Public
Switched Telephone Network.
