ETSI ETSI EN 300 197 V1.5.1 (2001-10)6 1 Scope The present document specifies the minimum performance parameters for terrestrial digital fixed service radio communications equipment operating in the 32 GHz and 38 GHz frequency. For spectrum efficiency class 5 for STM-1 capacity for 28 MHz Adjacent Channel Alternate-Polarization (ACAP as class 5a) and Adjacent Channel Co-Polarization (ACCP as class 5b), see examples of the spectrum usage in figures 1.1a and 1.1b:

Figure 1 NOTE: In the version 1.2.2 of EN 300 197 [35] there was provision for: - parameters for wideband analogue systems; - further options for digital radio systems (there referred as Grade A systems); - specific antenna radiation patterns (now superseded by EN 300 833 [3]). These options are not reprinted in this version as they are considered to be no longer of interest for ETSI members. However, for regulatory purposes, they may still be referenced from version 1.2.2 of EN 300 197 [35]. Digital systems are intended to be used for point-to-point connections in local and regional networks at data rates between 2 Mbit/s and Synchronous Transport Module, level 1 (STM-1). 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 the same route, connected to separate antennas; 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 high capacity Plesiochronous Digital Hierarchy (PDH) transmission systems, STM-0 and STM-1 Synchronous Digital Hierarchy (SDH) transmission systems. Antenna/feeder system requirements are covered in EN 300 833 [3]. The present document does not contain aspects related to test procedures and test conditions however they are to be found in EN 301 126-1 [2]. As the maximum transmission rate in a given bandwidth depends on system spectral efficiency, different equipment classes are defined: Class 2: equipment spectral efficiency based on typically 4-states modulation scheme (e.g. 4-FSK, 4-QAM, or equivalent); Class 3: equipment spectral efficiency based on typically 8-states modulation scheme (e.g. 8-PSK, or equivalent); Class 4: equipment spectral efficiency based on typically 16 or 32-states modulation scheme (e.g. 16-QAM, 32-QAM, or equivalent); Class 5: equipment spectral efficiency based on typically 64 or 128-states modulation scheme (e.g. 64-QAM, 128-QAM, or equivalent). SIST EN 300 197 V1.5.1:2003

ETSI ETSI EN 300 197 V1.5.1 (2001-10)7 The above classes are indicative only and do not imply any constraint to the actual modulation format, provided that all the requirements in the present document are met. Safety aspects will not be considered in the present document. However compliance to EN 60950 [30] will be required to comply with 99/5/EC [31] Directive (R&TTE). Technical background for most of the parameters and requirements referred in the present document may be found in TR 101 036-1 [26]. 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.

The channel arrangements in the band 31,8 GHz to 33,4 GHz shall be in accordance with CEPT/ERC Recommendation T/R 01-02 [1] or ITU-R Recommendation F.1492 [33]. For reader convenience, the basic parameters of the CEPT Recommendation are shown in annex A, clause A.1.1.1. In addition to this channel plan an interleaved channel plan is allowed by this ERC Recommendation. The 31,0 GHz to 31,3 GHz band is available in some countries and included in the CEPT Report 25. Moreover the band 31,5 GHz to 31,8 GHz may be used on a national basis (see footnote S5.5461 of the Radio Regulations). The present document therefore also covers the bands 31,0 GHz to 31,3 GHz and 31,5 GHz to 31,8 GHz provided that the channel arrangement is based on the channel separation as stated in the CEPT Recommendation 01-02 for the band 31,8 GHz to 33,4 GHz. 4.1.1.2 Frequency arrangement for 38 GHz The frequency range shall be 37 GHz to 39,5 GHz. The channel arrangements shall be in accordance with CEPT Recommendation T/TR 12-01 [1]. For reader convenience, the basic parameters of the CEPT Recommendation are shown in annex A, clause A.1.2. 4.2 Channel spacing for systems operating on the same route System bit rates and their relevant channel spacing in the present document are reported in table 1 (for the precise payload bit rates, see clause 5.1). NOTE: According to systems characteristics the equipment can be connected either to separate antennas or on a separate polarization to the same antenna. SIST EN 300 197 V1.5.1:2003
