Foreword This European Standard (Telecommunications series) has been produced by ETSI Technical Commit

17、tee Transmission and Multiplexing (TM). The present document contains the minimum technical requirements to ensure compatibility of products and conformance with radio regulations across ETSI member states. Radio equipment from different manufacturers are not required to interwork at radio frequency

18、 (i.e. no common air interface). The present document defines the requirements for radio-relay equipment and associated interfaces. The present document is intended to cover a variety of systems designed for a variety of services, applications, performance objectives and deployment conditions. There

19、fore it is necessary if applicable to include in the present document different sets of system parameters. In the present document these sets of parameters are referred to as “system types“. The present document is part 1 of a multipart deliverable covering the Point-to-multipoint equipment; Point-t

20、o-multipoint digital radio systems in frequency bands in the range 24,25 GHz to 29,5 GHz using different access methods. as identified below: Part 1: “Basic parameters“; Part 2: Part 3 : Part 4: Part 5: “Frequency Division Multiple Access (FDMA) methods“; “Time Division Multiple Access (TDMA) method

21、s“; “Direct Sequence Code Division Multiple Access (DS-CDMA) methods“; “Multi-Carrier Time Division Multiple Access (MC-TDMA) methods“. Parts 2,3,4 and 5 are intended to be used in conjunction with the present document, describing the basic parameters common to all access methods. References in EN 3

22、01 213 parts 2 4, 3 5, 4 6 and 5 7 to technical parameters for P-MP systems apply equally to MP-MP systems. A basic description of the different access methods and a comparison among them are provided in TR 101 274 SI. The present version differs from the previous one for editorial up-dating consequ

23、ent to the publication of new ERC Recommendations for FWA in these bands, to publication of EN 301 213-4 6 and EN 301 213-5 7 and to recent terminology used in the other parts of the present document. Moreover, alignment to the recent status of EMC ENS harmonized under R - concentration; - transpare

24、ncy. Radio is often the ideal way of obtaining communications at low cost and almost independent of distance, and difficult topography. Moreover, a small number of sites are required for these installations, thus facilitating rapid implementation and minimizing maintenance requirements of the system

25、s. Concentration means that m subscribers can share n radio channels (m being larger than n), allowing a better use to be made of the available frequency spectrum and at a lower equipment cost. The term “multi-access“ derives from the fact that every subscriber has access to every channel (instead o

26、f a fixed assignment as in most multiplex systems). When a call is initiated one of the available channels is allocated to it. When the call is terminated, the channel is released for another call. Concentration requires the use of distributed intelligent control which in turn allows many other oper

27、ations and maintenance functions to be added. Transparency means that the exchange (service node) and the subscriber equipment communicate with each other without being aware of the radio link. ETSI 7 ETSI EN 301 213-1 V1.1.2 (2002-02) 1 Scope The present document specifies the minimum requirements

28、for system parameters of Point-to-Multipoint (P-MP) Radio and Multipoint-to-Multipoint (MP-MP) Systems in the terrestrial Fixed Services (FS) operating in the bands 24,5 GHz to 29.5 GHz. Multipoint (MP) Radio-Relay Systems use in principle three different access methods, taking into account the basi

29、c physical parameters of the frequency, the code and the time. This leads to the three basic access methods of: - - - Frequency Division Multiple Access (FDMA); Code Division Multiple Access (CDMA); Time Division Multiple Access (TDMA). In addition, in particular for wide-band applications, a multi-

30、carrier transmission implementation may be applied, where each sub-carrier uses one of the above access methodologies. It should be noted that MP-MP systems differ from P-MP systems in that Terminal Stations may be connected directly to one another in a series of short links and generally act as rep

31、eaters for traffic carried on to other stations. The arrangement of links varies over time to accommodate changes in propagation characteristics and changes in the subscriber base. The MP system in the band 24,5 GHz to 29,5 GHz (ERC/REC T/R 13-02 i) will provide access to both public and private net

32、works (PSTN, PDN, etc.) by means of the various standardized network interfaces (e.g. 2-wire loop and ISDN ranging from basic rate to n x 2 Mbit/s as well as local area to wide area data networks interfaces). The system may be applied to build new access networks by means of a multi cellular archite

33、cture, covering urban and suburban areas. MP systems are generally configured as Pre-Assigned Multiple Access (PAMA) or as Demand Assigned Multiple Access (DAMA) Radio Systems. The present document covers the following MP applications: - voice; - fax; - voice band data; - telex; related to analogue

34、interfaces; and - 64 kbit/s; - ISDN; - digital video; - digital audio; - Internet access; related to digital interfaces; - further applications like ATM, Frame Relay, LAN, WAN may also be provided. The equipment covered by EN 301 213 should be designed to be able to meet the network performance requ

35、irements foreseen by ITU-R Recommendations F.696-2 9 and F.697-2 lo, for medium and local grade portion or ITU-R Recommendation F. 1189-1 i 11 for the national portion (access or short haul) of the digital connection following the criteria defiied in ITU-T Recommendation(s) G.821 12 andor G.826 13.

36、The availability requirements are under further study by the relevant bodies. ETSI 8 ETSI EN 301 213-1 V1.1.2 (2002-02) Network operators may choose different performance and availability requirements in order to extend the possible area of application thus fitting to their network needs. Radio term

37、inals from different manufacturers are not intended to interwork at radio frequency (i.e. no common air interface). Regulatory bodies should take into account the inband coexistence between MP systems using differing access methods. The present document defines the requirements of radio terminal and

38、 radio-relay equipment including the interfaces. The requirements for multiplex, network management and antenna/feeder equipment may be addressed elsewhere. 2 Re fe re nces The following documents contain provisions which, through reference in this text, constitute provisions of the present document
