2、ERC/DEC/(94)03-ENGL 3994 6 2326434 OOL44Yb 35T m Copyright 1994 the European Conference of Postal and Telecommunications Admmktrations (CEPT) EXPLANATORY MEMORANDUM i. INTRODUCTION The DECT (Digital European Cordless Telecommunications) standard covers cordless communications for voice and data. The
3、 intention is for one standard to provide voice and data telecommunications at home, in the office and in the street. The system is intended to allow user densities up to one hundred times those of cellular radio systems. The base stations will have theoretical fiee-space coverage diameters of up to
4、 50Om; normal coverage in the office will be 50-1OOm. When ushg the allocated 20 MHz of frequency spectrum, a cell may have a theoretical peak capacity of between 50 to 144 voice channels depending on overlap with other DECT cells. The core technology is intended to be able to support second generat
5、ion advanced applications with existing installed infrastructure. DECT system designers will have the advantage of being able to tailor the air interface technology to meet the majority of these applications, and DECT will therefore go a lot further than other cordless standards and could facilitate
6、 these more advanced applications. 2. BACKGROUND The past few years have seen an increasing number of developments in Europe in the field of cordless telephony. Amongst these have been the emergence of new standards including CT1+ as an enhanment of the CEPT CTl standard, CT2 used primarily for Tele
7、point applications and DCT 900 for Wireless PBX use. CEPT esbblished a sub-working group to prepare a specication for a Digital European Cordless Telectnnmunications system, now known as DECT. The DECT specification will define a radio access technique which couid be used to replace the fixed Wire c
8、onnection both to the PSTN and the fature ISDN. As such it will offer a significantly greater capability to users than a simple cordless telephone system. Since DECT will provide an extension to the PSTNflSDN, most applications of the fixed network will be able to be supported by DECT. In addition,
9、since a radio link replaces the fixed link, these applications could be mobile. In 1989, CEPT agreed Recommendation TBR 22-02 which designated the band 1880-1900 MHz for DECT. In 1991, Council of the European Communities adopted a Directive which required member states to designate 1880-1900 MHz for
10、 DECT and to ensure that any services remaining in this band do not interfere with any DECT systems that may be established according to commercial demand. 3. REQUIREMENT FOR AN ERC DECISION The allocation or designation of a fiequency band for its use by a service or system under specified conditio
11、ns in CEPT member countries is laid down by law, regulation or administrative action. The ERC recognises that for DECT to be introduced successfully throughout Europe, manufacturers and operators must be given the confidence to make the necessary investment in this new pan-European radioconununicati
12、on system and service. Therefore ERC believes it is necessary to designate a fiequency band to be used by the DECT system under specified conditions. A commitment by CEPT member countries to implement an ERC Decision will provide a clear indication that the required fiequency band will be made avail
13、able on time and on a Europe-Wide basis. Council Directive on the frequency band to be designated for the coordinated introduction of digital European cordless telecommunications (DEO into the Community. (91/287/EEC) 1 ERC DECISION of 24th October 1994 on the frequency band to be designated for the
14、coordinated introduction of the Digital European Cordless Telecommunications system (ERC/DEC/(94)03) The European Conference of Postal and Telecommunications Administrations, considering a) that current cordless telephone systems in use in Europe and the fiequency bands they operate in, vary widely
15、and may not allow the benefits of Europe-wide services or benefit fkom the economies of scale associated with a truly European market, b) that the European implementation of DECT will provide an important opportunity to establish truly European digital cordless telephone facilities, c) that the Euro
16、pean Telecommunications Standard Institute (ETSI) has developed the European Telecommuniations Standards for DECT, d) that market studies have indicated that the estabiishment of DECT on a Europe-wide basis will require the designation of a common 20 MHz fiequency band for the time division duplex t
17、ransmission between the xed and portable stations, e) that this frequency band can be made available progressively in order to satisfy commercial demand, f) that Member States of the European Union have implemented the Council Directive (91/287/EEC) and Council Recommendation 91/288/EEC. g) that sev
18、eral non-EEA countries have become associate members of the European Union and have expressed their intention to implement the existing EU legislation, DECIDES 1. that for the purposes of this Decision, the Digital European Cordless Telecommunications (DECT) shall mean equipment complying with the E
19、uropean Telecommunications Standards and the telecommunications systems, both public and private, which directly utilise DECT technology, 2. to designate the fiequencyband 1880-1900 MHz for DECT from 24th October 1994, 3. that DECT shall have priority over other radio systems in that band, and be pr
