4、tions throughout Europe regarding availability of frequency bands, approval requirements and border crossing procedures. A basic requirement to fulfil these objectives is the Europe-wide implementation of national regulations based on the European Standards (Telecommunication series) (ENS) developed
5、 by the European Telecommunications Standards Institute (ETSI). This Decision (ERC/DEC/(98)09) provides the necessaty mechanism for CEPT Administrations to commit themselves to implement, within their national regimes, European Telecommunications Standard 300 198 and withdraw any conflicting nationa
6、l standard. 2 BACKGROUND Both the ERC and ETSI are involved in the development of common regulations, as described in (1) above. The Memorandum of Understanding between ERC and ETSI explains the respective responsibilities of the two organisations and its annex describes the principles of co-operati
7、on. The ERC, for its part, should, inter alia, adopt Decisions on the introduction of ETSI standards into approval regimes. EN 300 198 V1.2.1 has been prepared by the Transmission and Multiplexing (TM) Technical Committee of ETSI. The standard has undergone the ETSI standards approval procedure and
8、is now published as an EN. The EN is based on CEPT Recommendation T/R 13-02. The use of the frequency range (21.2 to 23.6 GHz ) covered by EN 300 198 V1.2.1 is not harmonised within CEPT. Administrations have adopted different arrangements, to meet national requirements, for frequency bands and chan
9、nel separations (3.5,7, 14,28,56 and I12 MHZ). Further, the equipment used in this frequency range is subject to national licensing and frequency planning which requires specification of, inter dia, frequency of operation and equivalent isotropically radiated power (e.i.r.p.). Nevertheless, there ar
10、e a number of parameters, in particular those considered by the ERC as essential for spectrum management purposes2, which can be harmonised by adopting within approval regulations the limit values and measurement methods provided in EN 300 198 V1.2.1. In the European Table of Frequency allocations f
11、or the year 2008 (ERC Report 25), the fixed service has been removed from the band 21.4 GHz - 22.0 GHz, reflecting the WARC-92 decision on the Broadcasting-Satellite Service (BSS) for High Definition Television (HDTV).

13、quencies and the complementary equipment approval regimes in CEPT Member countries are laid down by law, regulation or administrative action. The ERC recognises that for harmonised fixed and mobile radio services to be introduced successfully throughout Europe, manufacturers and operators must be gi
14、ven the confidence to make the necessary investment in the development and procurement of new systems. Commitment by CEPT Administrations to implement this ERC Decision will provide a clear indication that equipment conforming to approval regulations based on EN 300 198 VI .2.1 will have the benefit
15、 of a Europe-wide market.

17、 frequencies and the related regulatory regimes; b) that such harmonisation will benefit administrations, manufacturers, operators and users; c) that ETSI has published EN 300 198 V1.2.1 for radio relay systems operating in the 21.2 to 23.6 GHz frequency range with channel separations of 3.5,7,14,28
18、,56 and 112 MHz; d) that EN 300 198 V1.2.1 supersedes ETS 300 198 and that, in due course, the ERC will abrogate its Decision, (ERC/DEC(96)09) associated with ETS 300 198; e) that, for the foreseeable future, there will continue to be widespread use of radio relay systems in the fixed service having
19、 the technical characteristics described in (c) above; f, that the European Table of Frequency Allocations (ERC Report 25) has identified the Broadcasting Satellite Service as the only primary service in the band 2 1.4 GHz - 22.0 GHz; g) that, in accordance with the Memorandum of Understanding betwe
