Foreword This European Standard (Telecommunications series) has been produced by ETSI Technical Committee Transmission and Multiplexing (TM). The present document is part 4 of a multi-part deliverable co
14、vering requirements for antennas in conjunction with MultiPoint (MP) systems necessary to facilitate frequency co-ordination between services in the frequency bands 11 GHz to 60 GHz, as identified below: Part 1: “General aspects“; Part 2: “24 GHz to 30 GHz“; Part 3: “Multipoint Multimedia Wireless S
15、ystem in 40,5 GHz to 43,5 GHz“; Part 4: “30 GHz to 40,5 GHz“. The present document is organized in the following way. Part 1 gives general information about the scope, normative references, definitions, classification, normative and informative electrical and mechanical characteristics. Part 1 is th
16、e framework for further parts, where distinct values of normative characteristics for a given frequency sub-band are defined. Consequently, part 1 in combination with another part forms the EN for a given sub-band. National transposition dates Date of adoption of this EN: 28 November 2003 Date of la

18、ent specifies the essential electrical requirements for linear polarization, fixed beam antennas to be utilized with new MultiPoint (P-MP and MP-MP) systems EN 301 997-1 1, including Central Station, Repeater and Terminal Station applications, operating in frequency bands from 11 GHz to 60 GHz. Thes
19、e systems use various multiple access schemes. Antennas may be aligned manually, by electromechanical or by switching between a set of antennas. Electronically steered antenna arrays, and circularly polarized antennas are not considered in the present document. The present document, taken together w
20、ith EN 301 215-1 4, specifies the requirements for multipoint systems operating in the frequency range 30 GHz to 40,5 GHz. A Regulatory Authority may impose tighter requirements than the minimum values given in the present document, in order to maximize the use of scarce spectrum resources. For some
21、 high gain 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 References The following documents contain provisions which, through reference in this text, const

43、tral station sectored elevation RPEs One symmetric CS antenna elevation RPE is defined in figure 7. For antennas designed without any tilt the 0 reference direction normally corresponds to the boresight direction. It may be necessary in practical deployments to use electrical or mechanical tilt, or
44、a combination of these two, to achieve the required cell coverage, taking into account the surrounding terrain, for example. ETSI ETSI EN 301 215-4 V1.1.1 (2003-12) 12The elevation pattern is considered appropriate to the commonly used range of 0 to -10 for electrical downtilt. A further mechanical
45、downtilt of up to 10 may be suitable for some situations. An electrical tilt is translated onto the corresponding pattern as a shift along the elevation angle axis. NOTE: Positive angles are for above boresight (up) and negative angles are for below (down). -40-35-30-25-20-15-10-500 1020304050607080
