Foreword This European Standard (Telecommunications series) has been produc

14、ed by ETSI Technical Committee Transmission and Multiplexing (TM). The present document was firstly started as part 2 of EN 301 631. It has been decided by ETSI Technical Committee Transmission and Multiplexing to publish it as a standalone document under EN 30 1 525 V1.l. 1. The purpose of the pres

15、ent document is to define the antenna performance standards necessary to ensure optimum frequency Co-ordination between like systems and/or different services by the Regulatory Authorities in the re-planned 1 GHz to 3 GHz band. The 3 GHz upper limit has been introduced making reference to the WARC 9

16、2 Final Acts 4 and the frequency plans as given in CEPT Recommendation T/R 13-01 i, ITU-R Recommendation F.746-3 2 and ITU-R Recommendation F. 1098 3. Antennas as components for radio relay systems may need to meet environmental, mechanical and electrical characteristics not covered by the present d

17、ocument, in order that the systems will operate as intended. Characteristics to be considered are provided as guidance in Annex A. 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 frequ

20、) systems, including central station and terminal station applications, operating in frequency bands from 1 GHz to 3 GHz. These systems use various multiple access schemes. Electronically steerable antennas, and circularly polarized antennas are not considered under the present document. Only in exc

21、eptional 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. The application of these rad

22、io systems is anticipated to be for point-to-multipoint links in local access networks and customer access links. 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 requireme
