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 [2] (as amended) 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").
The previous V1.1.1 the present document has become a Harmonized Standard, the reference of which has been
published in the Official Journal of the European Communities (OJEC) 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").
The present document intends to endorse, within the scope and applicability under the R&TTE Directive [1], some new
product standards and revisions of existing product standards. These have been produced by TC-TM, following the
market demand, after the publication in the OJEC of the V1.1.1 of the present document.
For systems already covered by V1.1.1 of the present document, only technically equivalent requirements have been
introduced by V1.2.1. Therefore, from a technical point of view only, it is expected that equipment already conforming
to V1.1.1, would not need re-assessment of the essential requirements for V1.2.1; however, legal implications on the
actual declaration of conformity and equipment labelling are outside the scope of the present document.
In addition, justification has been introduced in order to support clarification of issues relating to antennas and receiver
parameters, commonly shared in the Fixed Service community, in their application and relationship to R&TTE
Directive [1] implementation. This is with the intention of preserving a common understanding of those issues, in the
spirit of maintaining market competition on equitable level.
In the present document the references to antenna cross-polar discrimination have been deleted because it is not
considered an essential requirement for multipoint systems.
NOTE: The date of cessation of presumption of conformity to R&TTE Directive [1] shall be two years after the
date of publication in the OJEC of V1.2.1.

Introduction
Fixed Digital Radio Systems (FDRS), used in European countries, are presently referred to in a relatively large number
of specific ETSI standards dealing with either point-to-point or multipoint systems.
For both types of systems the corresponding antennas are covered in separate standards.
FDRS cover very wide range of frequency bands, transport capacities, channel separations, modulation formats and
access methods summarized in table 1:
Table 1: Coverage of fixed digital radio systems through ETSI standards
Parameter Range/Type
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 links applying low/medium and high capacity
FDRS.
POINT-TO-MULTIPOINT (P-MP) AND/OR MULTIPOINT-TO-MULTIPOINT
(MP-MP) CONNECTIONS:
rural or urban for narrow-band and /or wide-band links for fixed wireless access
(FWA) and infrastructure support.
STAND ALONE ANTENNAS:
for all the above applications where integral antennas are not used.
Basic MultiPoint access DS-CDMA; FH-CDMA; FDMA, TDMA; MC-TDMA.
method A combination of the above may also be used.

In order to address different market and network requirements, with appropriate balance of cost/benefit, the ETSI
standards summarized in table 2 offer a number of system types and antenna alternatives, for different network/market
requirements.
Under the provision of R&TTE Directive [1] article 7.2, national regulatory bodies may restrict the putting into service
of particular system and antenna alternatives summarized in table 2, e.g.:
• channel separation alternatives (as provided by the relevant CEPT Recommendation)
• spectral efficiency class alternatives (different complexity of modulation formats provided in radio equipment
standards)
• antenna directivity class alternatives (for different network density requirement) for TS and/or RS
• antenna sectorization alternatives for CS
Therefore, it should be noted that national regulatory bodies may have notified "national interface specifications" under
the provision of R&TTE Directive [1] Article 4.1.
The standards also contain other requirements that even if not considered essential for the R&TTE Directive [1], are
nevertheless applicable to guarantee good performance and operability of FDRS.

This wide range of parameters has led to a large number of different ETS/ENs (presently the subject of EC
Standardization Mandate M/284 [34]). Many of the standards are produced for similar systems but having different
capacity and spectrum efficiency parameters for applications in the various radio frequency channel arrangements
recommended by CEPT/ECC. It is also expected that other standards will be developed in the future to cover emerging
technologies and/or new frequency bands.
From the point of view of essential requirements under the R&TTE Directive [1] all these systems are very similar in
the "principles of parameters" but, besides few common horizontal parameters (e.g. spurious emissions), they differ in
the "required numerical values".
Multipoint systems and their related equipment as defined by ETSI TC-TM TM4 follow the general system architecture
shown in figure 1.

Figure 1 shows the most common and standardized approach for access network application; however when broadcast
or private networks are concerned, different architectures are possible. For example the CS may be directly connected to
the Core Network by means of a NNI interface and the switching functionality may be implemented within the CS
(e.g. CS is an ATM switching into an ATM network) and, for private networks, the UNI interfaces may be substituted
by custom interfaces.
Whenever an existing digital transmission link is available, the network implementation can be optimized by separating
the CCS, installed at the network node site, and the CRS.
Figure 1 includes the system elements and interfaces for different types of Multipoint system (both P-MP and MP-MP).
Not all system elements are necessarily deployed in any particular network.
The numbers of each type of station in a real deployment can vary considerably. Figure 1 shows only each possible type
of station and each possible type of connection between stations that may occur. While in P-MP applications there are
typically few CS and RS connecting large number of TS, in a typical MP-MP system, there are many RS stations and a
smaller number of TS stations associated with each CS.
Although a single CS is possible, as shown, a typical system will deploy several CS, each with connection to the SNI of
the local switching centre or directly to the NNI of the core network(s). These interconnections may be by means of
radio links, optical fibre or other means.
The route from the SNI to the UNI interface may be via a single radio path (typical for P-MP systems) or via one or
more radio repeaters (typical for MP-MP systems).
Subscriber to subscriber connections may also be provided in some networks, not routed via an external core network.
The present document for multipoint systems contains only the phenomena relevant to the essential requirements
according to article 3.2 of the R&TTE Directive [1], giving the reference of the relevant clauses of the ETSI standards
under the Mandate M/284 [34] which contain the actual numerical values. The relevant test methods for the declaration
of conformity to the essential requirements (R&TTE Directive [1]) are described in the ENs 301 126-2-1 [26],
301 126-2-2 [27], 301 126-2-3 [28], 301 126-2-4 [29], 301 126-2-5 [30] and 301 126-2-6 [39] applicable for the
different access methods of multipoint systems.
Where appropriate some horizontal requirements are directly reported.
The selection of the phenomena relevant to the essential requirements has been done on the base of the guidance given
by EG 201 399 [35] and by the further specific analysis applied to FDRS given in TR 101 506 [36].
ETSI has designed a modular structure for the standards. Each standard is a module in the structure. The modular
structure is shown in figure 2.

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 European 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 EN 301 489, the multi-part product EMC standard for radio used under the EMC
Directive [40].
For article 3.1a the diagram shows the existing safety standards currently used under the LV Directive [41] and new
standards covering human exposure to electromagnetic fields. New standards covering acoustic safety may also be
required.
The bottom of figure 2 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 European 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 European 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 FDRS types:
1) Multipoint FDRS intended for operation in frequency bands that require co-ordination; this includes both
Point-to-MultiPoint and MultiPoint-to-MultiPoint FDRS;
2) Antennas for multipoint FDRS and antennas for point-to-point FDRS used at the terminal and/or repeater
station of multipoint FDRS systems. These antennas may be either an integral part or may be used as a
standalone part of the equipment (outdoor unit).
For point-to-multipoint equipment operating in the frequency range below 1 GHz the limits of the essential
phenomena off-axis EIRP density, antenna gain and cross-polar discrimination as well as their test methods
may be defined by the notified body according to the R&TTE Directive [1] due to lack of a Harmonized
Standard.
The present document is intended to cover the provisions of Article 3.2 of the R&TTE Directive [1] which states that
"….radio equipment shall be so constructed that it effectively uses the spectrum allocated to terrestrial/space
radiocommunications 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 (www.etsi.org).
Table 2 summarizes the ETSI standards applicable to multipoint FDRS referenced in Mandate M/284 [34] from which
the essential requirements within this standard have been extracted.
Those ENs also contain other requirements that even if not considered essential for the R&TTE, are nevertheless
applicable on the ETSI commonly understood voluntary base to guarantee network performance objectives, as defined
by international standardizing bodies, and operability of FDRS.
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 essential requirements within that version.
