Foreword This European Standard (Telecommunications series) has been produced by ETSI Technical Committee Transmission and Multiplexing (TM). The present document has already been published as an ETSI Technical Specification, under TS 101 785. This V1.2.1 contains full formal revision, in term of definitions of spectral efficiency, now referenced to other existing ENs for conventional PDH/SDH application in the same frequency bands. The former title of the present document V1.1.1 was "Fixed Radio Systems; Point-to-point equipment; Parameters for packet data radio systems for transmission of digital signals operating in the frequency range 23, 26, 28 or 38 GHz".

ETSI ETSI EN 301 785 V1.2.1 (2002-02)5 1 Scope The present document specifies the minimum performance parameters for terrestrial fixed service radio communications equipment operating at 7, 8, 13, 15, 18, 23, 26, 28, 32, 38, 52 to 55 GHz provided with a combination Packet data interfaces or of Packet Data interfaces and PDH/SDH interfaces. Such digital systems are intended for use for point-to-point connections in local and regional networks. For regulatory purpose, reference shall be made to existing PDH/SDH standards to be used to assess the efficient use of radio spectrum. 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. NOTE: In the case of non-specific references, the time frame of application and new certification procedures for new releases of these normative references after the date of the first public enquiry of the present document or the first certification of the equipment shall be agreed between the supplier and the regulatory authority. These new certification procedures will cover in any case only the parameters subject to changes from the on going release during the previous certification.
