1 Scope

The present document specifies the minimum performance parameters for terrestrial digital fixed service radio

communications equipments operating in the 55 GHz frequency band and is a complete revision of the existing

ETS 300 407 [8] specification in the areas of:

- introduction of unique system type codes for regulatory reference to the various system types detailed in the

present document, refer to new annex C (normative) and related categories of equipment classes of spectral

efficiency;
- additional systems with higher spectrum efficiency in the new classes 1 to 4;
- removal of Analogue services;
- digital services restricted to frequency division duplex (FDD) operation only;

- technical specifications relevant to the EMC Directive, detailed in annex B (normative);

- specific antenna radiation patterns (now superseded by EN 300 833 [12]).

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).

Digital systems considered in the present document will be able to meet the error performance objectives of the ITU-R

national portion of the reference path, i.e. ITU-R Recommendation F.1189 [19] and the error performance objectives

detailed in ITU-T Recommendation G.826 [26].
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, and STM-0 and STM-1 Synchronous Digital

Hierarchy (SDH) transmission systems. Antenna/feeder system requirements are covered in EN 300 833 [12].

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 [3].

As the maximum transmission rate in a given bandwidth depends on system spectral efficiency, different equipment

classes are defined:

Class 1: equipment spectral efficiency based on typically 2-states modulation scheme (e.g. 2-FSK,

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. 8PSK, or

equivalent);

Class 4: equipment spectral efficiency based on typically 16 or 32-states modulation scheme (e.g. 16-

QAM, 32-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 are not considered in the present document. However compliance to EN 60950 [34] will be required to

comply with the 1999/5/EC Directive (R&TTE) [35].

Technical background for most of the parameters and requirements referred in the present document may be found in

TR 101 036-1 [14].
