scope:

The present document specifies the minimum performance parameters for terrestrial digital fixed service radio communications equipments operating in the 23 GHz frequency band and contains a complete revision in the areas of:

- additional systems with higher spectrum efficiency in the new class 4 systems;

- introduction of unique system type codes for regulatory reference to the various system types detailed in the present document, refer to new annex C and related categories of equipment classes of spectral efficiency;

- change of spectrum mask and adjacent channel selectivity of STM-0 systems in 28 MHz channel spacing to align to EN 300 639 [33];

- introduction of new 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;

- technical specifications relevant to the EMC Directive, detailed in annex B.

NOTE: In a previous version of the present document 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- specific antenna radiation patterns (now superseded by EN 300 833 [3]).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 the previous version.

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 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 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 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, or equivalent);

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-states or 128-states modulation scheme (e.g. 64-QAM, 128-QAM, or equivalent).

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 [34] will be required to comply with 1999/5/EC [35] 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 [30].
