Foreword This European Standard (Telecommunications series) has been produced by ETSI Technical Committee Transmission and Multiplexing (TM). The present document is part 3 of a multi-part deliverable covering requirements for antenna
13、s 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: Part 4: “Multipoint Multimedia Wireless system in 40,5 GHz to 4
14、3,5 GHz“; “Multipoint Multimedia Wireless system in 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. P
15、art 1 is the framework for fkther 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: Date of latest an

17、document specifies the essential electrical requirements for linear polarization, fixed beam antennas to be utilized with new multipoint (P-MP and MP-MP) Multimedia Wireless Systems (MWS), including central station, repeater and terminal station applications, operating in frequency bands from 11 GHz
18、 to 60 GHz. These 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,
19、taken together with EN 301 215-1 5, specifies the requirements for MWS (Multimedia Wireless Systems) 3 operating in the frequency range 40,5 GHz to 433 GHz. A Regulatory Authority may impose tighter requirements than the minimum values given in the present document, in order to maximize the use of s
20、carce spectrum resources. For some 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 2. 2 Re fe re nces The following documents contain provisions which, through ref
