1 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 [32];
- 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 EN 300 198 (V1.2.2) 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- specific antenna radiation patterns (now superseded by EN 300 833 [3]).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 EN 300 198 (V1.2.2).
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 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 are outside the mandate of ETSI and they will not be considered in the present document. However
compliance to EN 60950 [33] will be required to comply with Directive 1999/5/EC [34] (R&TTE).
Technical background for most of the parameters and requirements referred in the present document may be found in
TR 101 036-1 [29].

4 General characteristics
4.1 Frequency bands and channel arrangements
4.1.1 Channel arrangements
The frequency range shall be 22 GHz to 22,6 GHz paired with 23 GHz to 23,6 GHz. The channel arrangements shall be
in accordance with CEPT Recommendation T/R 13-02 [1].
For reader convenience, the basic parameters of the CEPT Recommendation are shown in annex A.
4.1.2 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.

Channel Class 2 equipments 3,5 3,5 7 14 28 56
Spacings [MHz] Class 4 equipments 3,5 7 14 14/28 56
Class 5 equipments 28
NOTE: n × 2 Mbit/s and n × 34 Mbit/s bit rates may be used where appropriate.
n × 2 Mbit/s mapped into SDH VC12 transport bit rates (sub-STM-0 defined by
ITU-T Recommendation G.708 [20]) may be used where appropriate (e.g. three or four times VC12 into an
8 Mbit/s channel spacing).
The class 2, 2 Mbit/s in 3,5 MHz and the class 4 in 28 MHz reflects equipment more typical to a class 1
(2 Mbit/s) and class 3 (STM-0) system and as a result the adjacent channel interference parameters are
more stringent.
For regulatory purposes in national procedures for licensing radio equipment according to the present document, the
above system types shall be identified by the "system type codes" reported in annex C.

4.2 Compatibility requirements between systems
The compatibility requirements between systems are as follows:
- there shall be no requirement to operate transmitting equipment from one manufacturer with receiving
equipment from another;
- there shall not be a requirement to multiplex different manufacturers equipment on the same polarization of the
same antenna;
- there may be a requirement to multiplex different manufacturers equipment on different polarization of the same
antenna. This will not apply to systems with integral antenna;
- depending on the application, it shall be possible to operate the system in vertical and/or horizontal polarization,
if required by the channel arrangement.
4.3 Performance and availability requirements
Digital equipment shall be designed in order to meet network performance and availability requirements foreseen by
ITU-T Recommendation G.826 [24], following the criteria defined in ITU-R Recommendations F.1189-1 [14] for the
national portion of the digital connection.
The implication of the link design on the performance is recognized and the general design criteria reported in ITU-R
Recommendations P.530-6 [16] and F.1102 [13] shall be applied.
