Foreword This European Standard (Telecommunications series)
13、 has been produced by ETSI Technical Committee Transmission and Multiplexing (TM). The present document is part 2 of a multi-part deliverable covering requirements for antennas in conjunction with multipoint (MP) systems necessary to facilitate frequency Co-ordination between services in the frequen
14、cy bands 11 GHz to 60 GHz. as identified below: Part 1 : “General aspects“; Part 2: “24 GHz to 30 GHz“; Part 3: Part 4: “Multipoint Multimedia Wireless system in 40,5 GHz to 43,5 GHz“; “Multipoint Multimedia Wireless system in 30 GHz to 40,5 GHz“ The present document is organized in the following wa
15、y. Part 1 gives general information about the scope, normative references, definitions, classification, normative and informative electrical and mechanical characteristics. Part 1 is the framework for further parts, where distinct values of normative characteristics for a given frequency sub-band ar
16、e defined. Consequently, part 1 in combination with another part forms the EN for a given sub-band.

18、h new Point-to-Multipoint (P-MP) systems EN 301 213-1 i, including central station and terminal station applications, operating in frequency bands from 11 GHz to 60 GHz. These systems use various multiple access schemes. Electronically steerable antennas, and circularly polarized antennas are not co
19、nsidered in the present document. The present document, taken together with EN 301 215-1 i, specifies the requirements for systems operating in the frequency range 24 GHz to 30 GHz. A regulatory authority may impose tighter requirements that the minimum values given in the present document, in order
20、 to maximize the use of the scarce spectrum resources. For some high gain, point-to-multipoint requirements, antennas may be used having performance as per the appropriate point-to-point antenna standard. For these antennas, minimum requirements are given in EN 300 833 2. 2 Refe re nces The followin

For antennas designed without any tilt the O“ reference direction normally corresponds to the
39、 boresight direction. It may be necessary in practical deployments to use electrical or mechanical tilt, or a combination of these two, to achieve the required cell coverage, taking into account the surrounding terrain, for example. The elevation pattern is considered appropriate to the commonly use
40、d range of O“ to -10“ for electrical downtilt. A further mechanical downtilt of up to I10“ may be suitable for some situations. An electrical tilt is translated onto the corresponding pattern as a O“ shift along the elevation angle axis. NOTE: Positive angles are for above boresight (up) and negativ
41、e angles are for below (down).
