Foreword
This Candidate Harmonized European Standard (Telecommunications series) has been produced by ETSI Technical
Committee Transmission and Multiplexing (TM).
The present document has been produced by ETSI in response to a mandate from the European Commission issued
under Council Directive 98/34/EC [30] laying down a procedure for the provision of information in the field of
technical standards and regulations.
The present document is intended to become a Harmonized Standard, the reference of which will be published in the
Official Journal of the European Communities referencing the Directive 1999/5/EC [1] of the European Parliament and
of the Council of 9 March 1999 on radio equipment and telecommunications terminal equipment and the mutual
recognition of their conformity ("the R&TTE Directive").

Introduction
Fixed Service Digital Radio systems, used in European countries, are presently referred to in a relatively large number
of specific ETSI standards.
These ETS/ENs contain other requirements that even if not considered essential under the R&TTE Directive [1] are
nevertheless applicable, on the ETSI commonly understood voluntary basis, to guarantee good performance and
operability of FDRS.
These standards either for point-to-point or for point-to-multipoint systems, cover a very wide range of frequency bands
of emission, traffic capacities, channel separations and modulation formats that, for the point-to-point systems subject
of this EN, are typically summarized in table 1.
Table 1: Fixed Service Digital Radio System (FDRS) parameters
Parameter Range
Frequency bands below 1 GHz to 58 GHz
Traffic capacities from 9,6 kbit/s to 622 Mbit/s
Channel separations from 25 kHz to 112 MHz
Modulation formats from 2 to 512 states (amplitude and/or phase and/or frequency states).
Typical applications POINT-TO-POINT (P-P) CONNECTIONS:
long haul (trunk), rural and urban low/medium/high capacity links
STAND ALONE ANTENNAS:
for all the above applications when integral antennas are not employed
Many of the standards are produced for similar systems which have different capacity and spectrum efficiency
parameters for applications in the various radio frequency channel arrangements as shown in table 1. It is expected that
other standards will be developed in the future to cover emerging technologies and / or new frequency bands.
All the systems are very similar in the "principles of parameters" but, besides a few common horizontal parameters,
they differ in the "required numerical values".
The present document, for point-to-point systems contains only the phenomena relevant to the essential requirements of
article 3.2 of the R&TTE Directive [1], giving the reference of the relevant clauses of the ETSI product standards which
contain the actual numerical values and the relevant test methods for the declaration of conformity to the essential
requirements.
Where appropriate some horizontal requirements are directly reported.
The selection of the phenomena relevant to the essential requirements has been based on the guidance given by
EG 201 399 [27] and by the specific analysis applied to FDRS given in TR 101 506 [28].
The present document is part of a set of standards designed to fit in a modular structure to cover all radio and
telecommunications terminal equipment under the R&TTE Directive [1]. Each standard is a module in the structure.
The modular structure is shown in figure 1.

The left hand edge of the figure 1 shows the different subclauses of Article 3 of the R&TTE Directive [1].
For article 3.3 various horizontal boxes are shown. Dotted lines indicate that at the time of publication of the present
document essential requirements in these areas have to be adopted by the Commission. If such essential requirements
are adopted, and as far and as long as they are applicable, they will justify individual standards whose scope is likely to
be specified by function or interface type.
The vertical boxes show the standards under article 3.2 for the use of the radio spectrum by radio equipment. The
scopes of these standards are specified either by frequency (normally in the case where frequency bands are
harmonized) or by radio equipment type.
For article 3.1b the diagram shows the new single multipart product EMC standard for radio, and the existing collection
of generic and product standards currently used under the EMC Directive [2]. The parts of this new standard will
become available in the second half of 2000, and the existing separate product EMC standards will be used until it is
available.
For article 3.1a the diagram shows the existing safety standards currently used under the LV Directive [3] and new
standards covering human exposure to electromagnetic fields. New standards covering acoustic safety may also be
required.
The bottom of the figure shows the relationship of the standards to radio equipment and telecommunications terminal
equipment. A particular equipment may be radio equipment, telecommunications terminal equipment or both. A radio
spectrum standard will apply if it is radio equipment. An article 3.3 standard will apply as well only if the relevant
essential requirement under the R&TTE Directive [1] is adopted by the Commission and if the equipment in question is
covered by the scope of the corresponding standard. Thus, depending on the nature of the equipment, the essential
requirements under the R&TTE Directive [1] may be covered in a set of standards.
The modularity principle has been taken because:
- it minimizes the number of standards needed. Because equipment may, in fact, have multiple interfaces and
functions it is not practicable to produce a single standard for each possible combination of functions that may
occur in an equipment;
- it provides scope for standards to be added:
- under article 3.2 when new frequency bands are agreed; or
- under article 3.3 should the Commission take the necessary decisions;
without requiring alteration of standards that are already published;
- it clarifies, simplifies and promotes the usage of Harmonized Standards as the relevant means of conformity
assessment.

1 Scope
The present document applies to the following fixed service digital radio systems (FDRS) types:
1) Point-to point systems intended for operation in frequency bands that require co-ordination;
2) Point-to point systems intended for operation in frequency bands that do not require co-ordination;
3) Antennas for point-to point FDRS.
The present document is intended to cover the provisions of Directive 1999/5/EC [1] (R&TTE Directive) Article 3.2
which states that "… radio equipment shall be so constructed that it effectively uses the spectrum allocated to
terrestrial/space radio communications and orbital resources so as to avoid harmful interference".
In addition to the present document, other ENs that specify technical requirements in respect of essential requirements
under other parts of Article 3 of the R&TTE Directive [1] may apply to equipment within the scope of the present
document.
NOTE 1: A list of such ENs is included on the ETSI web site at http://www.newapproach.org.
Table 2 summarizes the ETSI standards applicable to point-to-point FDRS, from which the technical parameters within
the present document have been extracted.
NOTE 2: The third digit of the EN version number is not considered essential for dated reference purposes because
the ETSI Technical Working Procedures reserve this digit for editorially changed versions, thereby not
affecting the technical parameters within that version.

NOTE: The frequency band identification is taken from the approximate centre frequency as commonly used in Fixed
Service ITU-R Recommendations; it also includes national frequency bands that may slightly differ from each
other but are commonly referred to by the same term.
The provisions of the present document are valid for all point-to-point (P-P) FDRS (Fixed Service Digital Radio
Systems) and related antennas also in the scope of the relevant ETSI standards summarized in table 1.
The present document is considered applicable to fixed radio systems products with integral antennas, for which all the
technical requirements included in the present document apply. It also applies to fixed radio equipment without integral
antennas and to separate antenna products, to which only the relevant technical requirements apply, and which will be
therefore subject to separate declarations of conformity to the essential requirements of the R&TTE Directive [1].
Technical specifications relevant to the R&TTE Directive [1] are summarized in Annex A.
