Foreword This European Standard (Telecommunications series) has been produced by ETSI Technical Committee Transmission and Multiplexing (TM). The purpose of the present document is to define the antenna performance standards necessary to ensure optimum frequency co-ordination between the systems and/or different services by the Regulatory Authorities in the 3 GHz to 11 GHz band. These nominal frequency limits have been chosen to reflect the WRC 2000 Final Acts [6] and the frequency plans as given in CEPT Recommendation T/R 13-02 [1] and ITU-R Recommendation F.748 [5]. Point-to-multipoint antennas, whether integrated within station equipment or not, may need to meet environmental, mechanical and electrical characteristics not covered by the present document, in order that the systems will operate as intended. Additional parameters and characteristics may be subject to agreement between the equipment purchaser and the supplier; these are considered and guidance is provided in annex A.

Introduction The purpose of the present document is to define the requirements for antennas used in conjunction with Point-to-MultiPoint (P-MP) systems necessary to facilitate frequency co-ordination between services in the frequency bands 3 GHz to 11 GHz. SIST EN 302 085 V1.2.2:2003

1 Scope The present document specifies the essential electrical requirements for linear polarization, fixed beam antennas to be utilized with new Point-to-Multipoint (P-MP) systems, including central station and terminal station applications, operating in frequency bands from 3 GHz to 11 GHz. These systems use various multiple access schemes. Electronically steerable antennas and circularly polarized antennas are not considered in the present document. Only in exceptional circumstances, and after a consultation period with operators and manufacturers, the Regulatory Authority may impose the use of tighter requirements than the minimum values given in the present document, in order to maximize the use of 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 [8]. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. • References are either specific (identified by date of publication and/or edition number or version number) or non-specific. • For a specific reference, subsequent revisions do not apply. • For a non-specific reference, the latest version applies.

CS: Central Station, which is linked to all remote stations (repeater or terminal stations) by microwave transmission paths. TS: Terminal Station (outstation with subscriber interfaces). RS: Repeater Station (radio repeater outstation with or without subscriber interfaces). A RS may serve one or more TSs.
