The present document applies to the following radio equipment types:
1) Repeaters for GSM;
These radio equipment types are capable of operating in all or any part of the frequency bands given in table 1-1.
NOTE: In some circumstances, for instance when an operator (or more than one operator who co-ordinate the use of repeaters), is not allocated a complete band as defined in table 1-1, it may be necessary to restrict the frequency range of operations of repeaters. In these circumstances, the test of "Gain outside operating band" in annex C may be used to verify the performance of the repeater. The present document covers requirements for GSM Repeaters for Release 8. The present document is intended to cover the provisions of Directive 1999/5/EC [i.2] (R&TTE Directive), article 3.2, which states that "... radio equipment shall be so constructed that it effectively uses the spectrum allocated to terrestrial/space radio communications and orbital resources so as to avoid harmful interference". 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 R&TTE Directive [i.2] may apply to equipment within the scope of the present document.

Globalni sistem mobilnih komunikacij (GSM) - 4. del: Harmonizirani EN za GSM ponavljalnike (repetitorje), ki zajema bistvene zahteve člena 3.2 direktive R&TTE

Pričujoči dokument velja za naslednje vrste radijske opreme:
1) ponavljalnike za GSM
Ti tipi radijske opreme so zmožni delovanja v vseh ali katerem koli delu frekvenčnega pasu, navedenem v preglednici 1-1.
OPOMBA: V določenih okoliščinah, na primer kadar operaterju (ali več kot enemu operaterju, ki usklajuje uporabo ponavljalnikov) ni dodeljen celotni pas, kot je določeno v preglednici 1-1, je potrebno omejiti frekvenčni razpon delovanj ponavljalnikov. V takih okoliščinah se lahko za potrditev delovanja ponavljalnika uporabi preskus »pridobi zunanji pas delovanja«, naveden v Dodatku C. Pričujoči dokument zajema zahteve za GSM ponavljalnike izdaje 8. Pričujoči dokument je namenjen temu, da zajema določbe Direktive 1999/5/ES (direktive R&TTE) [i.2], člena 3.2, ki navaja, da » … radijska oprema je narejena tako, da učinkovito izrablja spekter, razporejen za prizemne/vesoljske radiokomunikacije in orbitalne vire, tako da ne pride do škodljivega motenja.« Poleg pričujočega dokumenta se ostali EN, ki določajo tehnične zahteve v skladu z bistvenimi zahtevami v drugih delih člena 3 direktive R&TTE [i.2], lahko uporabljajo za opremo znotraj področja uporabe pričujočega dokumenta.

Foreword This Harmonized European Standard (Telecommunications series) has been produced by ETSI Technical Committee Mobile Standards Group (MSG). The present document has been produced by ETSI in response to a mandate from the European Commission issued under Council Directive 98/34/EC [i.1] (as amended) laying down a procedure for the provision of information in the field of technical standards and regulations. The present document is intended to become a Harmonized Standard, the reference of which will be published in the Official Journal of the European Communities referencing the Directive 1999/5/EC [i.2] of the European Parliament and of the Council of 9 March 1999 on radio equipment and telecommunications terminal equipment and the mutual recognition of their conformity ("the R&TTE Directive"). The requirements relevant to Directive 1999/5/EC [i.2] are summarized in annex A.

Introduction The present document is part of a set of standards developed by ETSI and is designed to fit in a modular structure to cover all radio and telecommunications terminal equipment within the scope of the R&TTE Directive [i.2]. The modular structure is shown in EG 201 399 [i.3]. SIST EN 300 609-4 V9.2.1:2010

ETSI ETSI EN 300 609-4 V9.2.1 (2010-10) 6 1 Scope The present document applies to the following radio equipment types: 1) Repeaters for GSM; These radio equipment types are capable of operating in all or any part of the frequency bands given in table 1-1. Table 1-1: GSM Repeater frequency bands

Direction of transmission GSM Repeater frequency bands P-GSM900 Downlink 935 MHz to 960 MHz Uplink 890 MHz to 915 MHz E-GSM900 Downlink 925 MHz to 960 MHz Uplink 880 MHz to 915 MHz R-GSM900 Downlink 921 MHz to 960 MHz Uplink 876 MHz to 915 MHz DCS1800 Downlink 1 805 MHz to 1 880 MHz Uplink 1 710 MHz to 1 785 MHz GSM450 Downlink 460,4 MHz to 467,6 MHz Uplink 450,4 MHz to 457,6 MHz GSM480 Downlink 488,8 MHz to 496 MHz Uplink 478,8 MHz to 486 MHz

NOTE: In some circumstances, for instance when an operator (or more than one operator who co-ordinate the use of repeaters), is not allocated a complete band as defined in table 1-1, it may be necessary to restrict the frequency range of operations of repeaters. In these circumstances, the test of "Gain outside operating band" in annex C may be used to verify the performance of the repeater. The present document covers requirements for GSM Repeaters for Release 8. The present document is intended to cover the provisions of Directive 1999/5/EC [i.2] (R&TTE Directive), article 3.2, which states that "... radio equipment shall be so constructed that it effectively uses the spectrum allocated to terrestrial/space radio communications and orbital resources so as to avoid harmful interference". 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 R&TTE Directive [i.2] may apply to equipment within the scope of the present document. NOTE: A list of such ENs is included on the web site http://www.newapproach.org. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
