EN 300 198 V1.2.1 (1998-02)71ScopeThe present document specifies the minimum performance parameters for terrestrial digital and analogue fixed serviceradio communications equipments operating in the 23 GHz frequency band and contains a complete revision in the areasof:-Electromagnetic Compatibility (EMC) standardization (i.e. ETS 300 385 [11] and ETS 300 339 [10] whereapplicable);-emissions and immunity at antenna port standardization activity (under study in TM4), new revised ITU-RRecommendation SM.329-7 [20] and the forthcoming CEPT Recommendation on spurious emissions;-conformance test standardization activity of test methods and test reports (i.e. EN 301 126-1 [2]).The present document does not cover aspects related to test procedures and test conditions which are in the scope ofEN 301 126-1 [2].Digital systems are intended to be used for point-to-point connections in local and regional networks at data ratesbetween 2 Mbit/s and Synchronous Transport Module, level 1 (STM-1). Typical applications include:a)customer connections;b)Integrated Services Digital Network (ISDN) extension;c)mobile base station connections.Digital systems considered in the present document will be able to meet the performance objectives of the ITU-Rnational portion of the reference path, i.e. ITU-R Recommendation F.1189 [17] and the performance objectives detailedin ITU-T Recommendation G.826 [29].Analogue systems are intended to be used in local television (TV) point-to-point contribution and point-to-multipointdistribution.The parameters to be specified fall into two categories:a)those that are required to provide compatibility between channels from different sources of equipment on thesame route, connected either:-to separate antennas; or-to separate polarizations of the same antenna;b)parameters defining the transmission quality of the proposed system.The present document deals with Radio Frequency (RF) and baseband characteristics relevant to low, medium and highcapacity Plesiochronous Digital Hierarchy (PDH) transmission systems, sub-STM-1 and STM-1 Synchronous DigitalHierarchy (SDH) transmission systems. Antenna/feeder system requirements are covered in ETS 300 833 [3].As the maximum transmission rate in a given bandwidth depends on system spectral efficiency, different equipmentclasses are defined:Class 1:equipment performance based on typically 2-states modulation scheme (e.g. 2-FSK (Frequency-Shift Keying), Gaussian Minimum Shift Keying (GMSK) with discriminator detection, orequivalent);Class 2:equipment performances based on typically 4-states modulation scheme (e.g. 4-FSK, 4 - QAM(Quadrature Amplitude Modulation), or equivalent);Class 3:equipment performances based on typically 16-states modulation scheme (e.g. 16-QAM, orequivalent).Some equipment types may benefit from some performance improvement due to the technology gap; for this reason twogrades of system performance, grade A and grade B are provided.Safety aspects are outside the mandate of ETSI and they will not be considered in the present document.SIST EN 300 198 V1.2.1:2005
