ETSI ETSI EN 300 224 V2.1.1 (2017-06) 8 1 Scope The present document applies to on-site and wide area paging equipme
41、nt, 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 si
42、ngle 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
43、 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 pr
44、esent 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 antenna connector; 2) ba
45、se station receivers, with a permanent 50 connector; 3) paging receiver, with or without an external 50 antenna connector. These radio equipment types are capable of operating in all or any part of the frequency bands given in table 1. Table 1: Radiocommunications service frequency bands Radiocommun
46、ications service frequency bands Transmit 25 MHz to 470 MHz Receive 25 MHz to 470 MHz NOTE: Frequencies and frequency bands, used for on-site paging equipment, are not harmonised throughout the community. The frequency band 47 MHz to 47,25 MHz and operating frequencies or operating bands within 440
47、MHz to 470 MHz, are recommended by CEPT/ECC in Report 25 i.5. 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 articl
48、e 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
49、 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. 2 References 2.1 Normative references References are specific, identified by date of publication and/or edition number or version number.
