EN 301 751 is likely to be published in the OJ in few months, it presently reflect the status of published TM4 ENs by end 2000 but there are already a number of new ENs and revisions undertaking ETSI approval process and a number in advanced work in TM4. These also need the possibility to benefit of a Harmonised EN for simplifying R&TTE conformance. Moreover some formal improvement might be necessary due to the necessary feedback of the initial period of application (e.g. for the receiver parameters and the antenna issue).

The information pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found in ETSI SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web server (http://webapp.etsi.org/IPR/home.asp). Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web server) which are, or may be, or may become, essential to the present document. Foreword This Candidate Harmonized European Standard (Telecommunications series) has been produced by ETSI Technical Committee Transmission and Multiplexing (TM), and is now submitted for the ETSI standards One-step Approval Procedure. The present document has been produced by ETSI in response to a mandate from the European Commission issued under Council Directive 98/34/EC (as amended) [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"). Technical specifications relevant to Directive 1999/5/EC [1] are given in annex A. This second version intends to endorse, within the scope and applicability under the R&TTE Directive [1] of the present harmonized EN, some new product standards and revisions of already considered product standards. They have been produced by TC-TM, following the market demand, after the publication in the OJ of the first version V1.1.1. For systems already covered by the previous version of the present document, only equal or technically equivalent requirements have been introduced by this second version. Therefore, from a strictly technical point of view only, it is expected that equipment already conforming to the previous version, would not need re-assessment of essential requirements according to this second version; 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 some positions, commonly shared in the Fixed Service community, on some areas not yet fully clarified in their application and relationship to R&TTE Directive [1] implementation. This with the intention of, at least, keeping a common understanding of those issues, in the spirit of maintaining market competition on equitable level.
Proposed national transposition dates Date of latest announcement of this EN (doa): 3 months after ETSI publication Date of latest publication of new National Standard or endorsement of this EN (dop/e):
6 months after doa Date of withdrawal of any conflicting National Standard (dow): 24 months after doa

Notes to the NSOs for the OAP procedure: In tables 2 to 14 reference is made to a specific version of a number of ENs; most of them are under amendment currently at various stages of approval. When these new or amended ENs are approved they should be published as ENs with the quoted version number (as currently required for dated references provisions in harmonized standards). Prior to the publication of the present document, references of table 2 will be updated to match with the current status of the references deliverables and the publication of the present document will be held until all the quoted versions are published. In the case that one or more of the revisions are unacceptably delayed beyond the end of this OAP, the reference will be changed to the previous published version of the EN and provision will be made for an amendment of the present document for endorsing such amendment. The present document does not introduce any new technical requirements beyond those already present in the ENs listed in table 2, currently approved or under approval procedure. Introduction Digital Radio systems for the Fixed Service, used in European countries, are presently referred to in a relatively large number of specific ETSI standards. These 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 Digital Fixed Radio Systems (DFRS). 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 the present document, are typically summarized in table 1. Table 1: Digital Fixed Radio System (DFRS) 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 DFRS 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. OSIST EN 301 751 V1.2.1:2003

The left hand edge of the figure 1 shows the different clauses 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, relevant to fixed links equipment, have been published on the EC OJ, and the existing separate product EMC standards will be superseded by the date reported in the EC OJ. 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. OSIST EN 301 751 V1.2.1:2003

1 Scope The present document applies to the following digital fixed radio systems (DFRS) 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 DFRS. 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 DFRS, 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. N.A.: Not applicable.
The provisions of the present document are valid for all point-to-point (P-P) DFRS (Digital Fixed Radio Systems) and related antennas also in the scope of the relevant ETSI standards summarized in table 1. OSIST EN 301 751 V1.2.1:2003
ETSI Final draft ETSI EN 301 751 V1.2.1 (2002-07) 10 In order to technically cover different market and network requirements, with appropriate balance of cost/benefit, the ETSI standards summarized in table 1 offers a number of system types and antennas alternatives, for different network/market requirements, including: • 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). However, the Fixed Service generally operate in not harmonized bands, therefore it is currently understood that National Regulatory Bodies can limit the licensing only to some selected alternatives according the provision of R&TTE Directive [1] article 7.2 "…for reasons related to the effective and appropriate use of the radio spectrum,.". In a long-term regime, it is desirable that the allowed alternatives be included within the "national interface notification" under the provision of R&TTE Directive [1] article 4.1 and also that the covered alternatives be mentioned in the "notification of the intention to place a DFRS on the national market" under the provision of R&TTE Directive [1] article 6.4. 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 would be therefore subject to separate declarations of conformity to the essential requirements of the R&TTE Directive [1]. In particular, it has to be noted that TCAM, while recognizing the "essentiality" of antenna directional requirements for some applications, including the Fixed Service, has deliberated that there should be no obligation for separate declaration of conformity for stand alone antennas and that the respect of the relevant essential requirements should be demanded to the final system integrator.
However, it has also been recognized that the assessment of article 3.2 requirements on the radio-sites is technically impractical. Therefore, it should not be forbidden to a supplier of DFRS antennas, who decides, under his responsibility, to declare compliance to the relevant harmonized standard (or part thereof, in this case), to affix the CE label to a stand-alone Fixed Radio antenna product, fulfilling all other obligation foreseen by R&TTE Directive [1]; in particular, providing information for the user on the intended use of the apparatus.

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 (as amended) [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"). Technical specifications relevant to Directive 1999/5/EC [1] are given in annex A. This second version intends to endorse, within the scope and applicability under the R&TTE Directive [1] of the present harmonized EN, some new product standards and revisions of already considered product standards. They have been produced by TC-TM, following the market demand, after the publication in the OJ of the first version V1.1.1. For systems already covered by the previous version of the present document, only equal or technically equivalent requirements have been introduced by this second version. Therefore, from a strictly technical point of view only, it is expected that equipment already conforming to the previous version, would not need re-assessment of essential requirements according to this second version; 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 some positions, commonly shared in the Fixed Service community, on some areas not yet fully clarified in their application and relationship to R&TTE Directive [1] implementation. This with the intention of, at least, keeping a common understanding of those issues, in the spirit of maintaining market competition on equitable level.

Introduction Digital Radio systems for the Fixed Service, used in European countries, are presently referred to in a relatively large number of specific ETSI standards. These 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 Digital Fixed Radio Systems (DFRS). 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 the present document, are typically summarized in table 1. Table 1: Digital Fixed Radio System (DFRS) 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 DFRS 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. SIST EN 301 751 V1.2.1:2004

Figure 1: Modular structure for the various standards used under the R&TTE Directive The left hand edge of the figure 1 shows the different clauses 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. SIST EN 301 751 V1.2.1:2004

For article 3.1b the diagram shows EN 301 489, the multi-part product EMC standard for radio used under the EMC Directive [2].
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. SIST EN 301 751 V1.2.1:2004

1 Scope The present document applies to the following digital fixed radio systems (DFRS) 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 DFRS. 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 DFRS, 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.

N.A.: Not applicable.
The provisions of the present document are valid for all point-to-point (P-P) DFRS (Digital Fixed Radio Systems) and related antennas also in the scope of the relevant ETSI standards summarized in table 1. SIST EN 301 751 V1.2.1:2004
ETSI ETSI EN 301 751 V1.2.1 (2002-11) 10 In order to technically cover different market and network requirements, with appropriate balance of cost/benefit, the ETSI standards summarized in table 1 offers a number of system types and antennas alternatives, for different network/market requirements, including: • 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). However, the Fixed Service generally operate in not harmonized bands, therefore it is currently understood that National Regulatory Bodies can limit the licensing only to some selected alternatives according the provision of R&TTE Directive [1] article 7.2 "…for reasons related to the effective and appropriate use of the radio spectrum,.". In a long-term regime, it is desirable that the allowed alternatives be included within the "national interface notification" under the provision of R&TTE Directive [1] article 4.1 and also that the covered alternatives be mentioned in the "notification of the intention to place a DFRS on the national market" under the provision of R&TTE Directive [1] article 6.4. 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 would be therefore subject to separate declarations of conformity to the essential requirements of the R&TTE Directive [1]. In particular, it has to be noted that TCAM, while recognizing the "essentiality" of antenna directional requirements for some applications, including the Fixed Service, has deliberated that there should be no obligation for separate declaration of conformity for stand alone antennas and that the respect of the relevant essential requirements should be demanded to the final system integrator.
However, it has also been recognized that the assessment of article 3.2 requirements on the radio-sites is technically impractical. Therefore, it should not be forbidden to a supplier of DFRS antennas, who decides, under his responsibility, to declare compliance to the relevant harmonized standard (or part thereof, in this case), to affix the CE label to a stand-alone Fixed Radio antenna product, fulfilling all other obligation foreseen by R&TTE Directive [1]; in particular, providing information for the user on the intended use of the apparatus. The final system integrator might benefit of such declaration of conformity for any final radio-site assessment obligations. In any case, the antenna manufacturer is expected to keep a technical construction file (according annex II of R&TTE) to be supplied, on request, to the radio system vendor or to the final system integrator. Technical specifications relevant to the R&TTE Directive [1] are summarized in annex A. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. • References are either specific (identified by date of publication and/or edition number or version number) or non-specific. • For a specific reference, subsequent revisions do not apply. • For a non-specific reference, the latest version applies.
