Foreword This European Standard (Telecommunications series) has been produced by ETSI Technical Committee Transmission and Multiplexing (TM). The present document contains the minimum technical requirements to ensure compa

25、tibility of products and conformance with radio regulations across ETSI member states. Radio equipment from different manufacturers are not required to interwork at radio frequency (i.e. no common air interface). The present document defines the requirements for radio-relay equipment and associated

26、interfaces. The present document is intended to cover a variety of systems designed for a variety of services, applications, performance objectives and deployment conditions. Therefore it is necessary if applicable to include in the present document different sets of system parameters. In the presen

27、t 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-to-multipoint digital radio systems in frequency bands in the range 24,25 GHz to 29,5 GHz using different access methods,

28、 as identified below: Part 1: “Basic parameters“; Part 2: “Frequency Division Multiple Access (FDMA) methods“; Part 3: “Time Division Multiple Access (TDMA) methods“; Part 4: “Direct Sequence Code Division Multiple Access (DS-CDMA) methods“; Part 5: “Multi-Carrier Time Division Multiple Access (MC-T

29、DMA) 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 301 213 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 des

30、cription of the different access methods and a comparison among them are provided in TR 101 274 8. The present version differs from the previous one for editorial up-dating consequent to the publication of new ERC Recommendations for FWA in these bands, to publication of EN 30 1 2 13-4 6 and EN 301

31、2 13-5 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; - transparency. Radio is often the ideal way of obtaining communications at low cost and almost independent of distance, and dif

32、ficult topography. Moreover, a small number of sites are required for these installations, thus facilitating rapid implementation and minimizing maintenance requirements of the systems. Concentration means that m subscribers can share n radio channels (m being larger than n), allowing a better use t

33、o 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 of a fixed assignment as in most multiplex systems). When a call is initiated one of the available channels is allocat

34、ed 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 operations and maintenance functions to be added. Transparency means that the exchange (service node) and the subscriber

35、equipment communicate with each other without being aware of the radio link. Scope The present document specifies the minimum requirements 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 ba

36、nds 24,s GHz to 29,5 GHz. Multipoint (MP) Radio-Relay Systems use in principle three different access methods, taking into account the basic physical parameters of the frequency, the code and the time. This leads to the three basic access methods of: - Frequency Division Multiple Access (FDMA); - Co

37、de Division Multiple Access (CDMA); - Time Division Multiple Access (TDMA). In addition, in particular for wide-band applications, a multi-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 diff

38、er 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 repeaters for traffic carried on to other stations. The arrangement of links varies over time to accommodate changes in propagation characteristics and changes in t

39、he subscriber base. The MP system in the band 24,s GHz to 29,s GHz (ERCIREC TR 13-02 I) will provide access to both public and private networks (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 Mbitls as well as loca

40、l area to wide area data networks interfaces). The system may be applied to build new access networks by means of a multi cellular architecture, covering urban and suburban areas. MP systems are generally configured as Pre-Assigned Multiple Access (PAMA) or as Demand Assigned Multiple Access (DAMA)

41、Radio Systems. The present document covers the following MP applications: - voice; - fax; - voice band data: - telex; related to analogue interfaces; and - 64 kbitls; - ISDN; - digital video; - digital audio; - Internet access; related to digital interfaces; - further applications like ATM, Frame Re

42、lay, LAN; WAN may also be provided. The equipment covered by EN 301 213 should be designed to be able to meet the network performance requirements 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. 11 89-1 1 11 for the national p

43、ortion (access or short haul) of the digital connection following the criteria defined in ITU-T Recommendation(s) G.82 1 12 andlor G.826 13. The availability requirements are under further study by the relevant bodies. Network operators may choose different performance and availability requirements

44、in order to extend the possible area of application thus fitting to their network needs. Radio terminals 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

45、using differing access methods. The present document defines the requirements of radio terminal and radio-relay equipment including the interfaces. The requirements for multiplex, network management and antennalfeeder equipment may be addressed elsewhere. References The following documents contain p
