Fixed Radio Systems; Point-To-Point Equipments and Antennas; Generic Harmonized Standard for Point-To-Point Digital Fixed Radio Systems and Antennas Covering the Essential Requirements under Article 3.2 of the 1999/5/EC Directive

inactive
Organization: ETSI
Publication Date: 1 July 2002
Status: inactive
Page Count: 38
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 .

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.

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 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.
