The present document applies to on-site paging equipment operating in the frequency range of 25 MHz to 470 MHz and
loop systems below 146 kHz.
NOTE: Frequencies and frequency bands, used for on-site paging equipment, are not harmonized throughout the
community. The frequency band 47 MHz to 47,25 MHz and operating frequencies or operating bands
within 440 MHz to 470 MHz, are recommended by CEPT/ERC in Report 25 [3].
The existence of a Harmonized Standard does not imply the availability of the above frequency spectrum
for the particular types of equipment covered by the present document.
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 paging system may be extended with a return frequency. This return or talk-back frequency is mainly used for call
acknowledgement but 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.
The types of equipment covered by the present document are as follows:
- base station transmitters (radio and loop) and transcoders, with or without an external 50 antenna connector;
- base station receivers, with a permanent 50 connector;
- pocket unit (receiver, transceiver or transmitter), with or without an external 50 antenna connector.
NOTE: The functional characteristics of an on-site paging system are described in ETS 300 224 [2].
