Fixed Radio Systems; Characteristics and requirements for point-to-point equipment and antennas; Part 3: Harmonized EN covering essential requirements of Article 3.2 of R&TTE Directive for equipment operating in frequency bands where no frequency co-ordination is applied

Through the notification of the UK interface regulation, the European Commission have strongly requested that ETSI TM4 consider a rationalisation of the number of fixed terrestrial (point-to-point) standards. This work item is therefore in response to this request and aims to simplify (and rationalise the number of)  existing standards.   This work item is to appraise only the published ETSI fixed terrestrial (point-to-point) radio relay standards and consolidate these into the new style generic format . The primary intention will be to rationalise the existing number of standards, in excess of 30, to just a handful, e.g. ideally 5. These standards will then be proposed as Harmonised Standards.  The preferred method of segmentation is yet to be decided, but this may be on the basis of  (frequency range or application or traffic capacity).  Annex A illustrates possible segmentation options.  The work will only consolidate new or existing work items on standards if the output deliverables are formally published before the completion of this work activity. Further, this work item does not, in principle, propose to change any existing technical parameter values, although the presentation of data/information may be modified to enhance understanding and usability leading to some new or revised requirements. The format shall be consistent across the range of standards which are segmented under the preferred method.

Introduction 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. Each standard is a module in the structure. The modular structure is shown in figure 1.

The left hand edge of 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. Whenever 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 (see bibliography), the multi-part product EMC standard for radio used under the EMC Directive 89/336/EEC (see bibliography). NOTE: For Fixed Radio Systems EN, EN 301 489-1 (see bibliography) and EN 301 489-4 (see bibliography) are relevant. For article 3.1a the diagram shows the existing safety standards currently used under the LV Directive 73/23/EEC (see bibliography) and new standards covering human exposure to electromagnetic fields. New standards covering acoustic safety may also be required. The bottom of the figure 1 shows the relationship of the standards to radio equipment and telecommunications terminal equipment. 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 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 specifies the essential requirements for Digital Fixed Radio Systems (DFRS) operating in frequency bands, which do not require co-ordinated frequency planning. It is intended to cover the provisions of Directive 1999/5/EC [1] (R&TTE Directive) regarding 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". The present document with EN 302 217-2-2 (see bibliography) and EN 302 217-4-2 [8] will replace and supersede, after a suitable transition period, the harmonized EN 301 751 (see bibliography) for all P-P equipment and antennas. Those parts of this multipart EN introduces, for systems (equipment and antennas) already covered by EN 301 751 (see bibliography), equal, technically equivalent or less stringent requirements. Therefore, from a strictly technical point of view, it is expected that equipment already conforming to the previous EN 301 751 (see bibliography), would not need a new test report for re-assessment of essential requirements according this new multipart EN; however, legal implications with respect to the declaration of conformity and equipment labelling are not in the scope of the present document. 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] will apply to equipment within the scope of the present document. NOTE: A list of such ENs is included on the web site http://www.newapproach.org. In order to technically cover different market and network requirements, with an appropriate balance of performance to cost and effective and appropriate use of the radio spectrum, the present document, together with EN 302 217-4-2 [8], offers system types and antennas alternatives, for selection by administrations, operators and manufacturers dependent on the desired use of the radio spectrum and network/market requirements, those options include: • channel separation alternatives (as provided by the relevant CEPT Recommendation); • implemented procedure for free radio channel selection; • antenna directivity class alternatives (for different network density requirement). The present document is mainly intended to cover fixed radio equipment without integral antennas. However, it also applies to fixed radio systems products with integral antennas, for which all the technical requirements included in the present document and in EN 302 217-4-2 [8] apply. For more background information on the equipment and antenna parameters here identified as relevant to article 3.2 of R&TTE Directive see EG 201 399 (see bibliography) and TR 101 506 (see bibliography). For example, the frequency band 58 GHz is proposed to be used by various technologies for uncoordinated use of the band. Besides the RF-channel selection procedure, specified in clause 4.2 to avoid unacceptable interference situations, this band also benefits from the high and stable atmospheric attenuation which suppresses efficiently distant interferers (about 10 to 15 dB/km at sea level, refer to ITU-R Recommendation P.676 (see bibliography). For the purposes of the present document two equipment Classes are specified depending on the network requirements: • Class A: Digital equipment for High Density Fixed Service (HDFS) applications typically connected to public networks, which apply the RF-channel selection procedure (see clause 4.2), error performance and availability requirements (see EN 302 217-1 [7]). • Class B: Equipment without network requirements for quality of service, typically private connections. Typical applications for Class A equipment are interconnection between cellular networks where, in some cases, there is a need for short length connections (up to about 500 m). The RF channel selection procedure shall be used to protect existing systems from a new system being commissioned. However, the channel selection procedure may not guarantee interference free installation or operation in all cases, due to limitations in the procedure with respect to the variety of systems. Typical applications for Class B equipment are in private connections, such as video surveillance systems. SIST EN 302 217-3 V1.1.3:2005

In the following clauses, limits are required to be met at specific reference points of the system block diagram. Reference points and the system block diagram are those set out in figure 1 of EN 302 217-1 [7]. In the case of wide radio-frequency bands covering units and multirate/multiformat equipment, these specifications shall be met at any frequency and at any rate/format. However the tests, required for generating a test report and/or declaration of conformity, in order to fulfil any conformity assessment procedure with respect to the R&TTE Directive [1], shall be carried-out in accordance with the principles set out in annex UC. Testing methods and conditions for assessing all requirements are specified in clause 5, where each clause directly refer to corresponding clause in this clause. 4.1 Environmental profile The technical requirements of the present document apply under the environmental profile for operation of the equipment, which shall be declared by the supplier. The equipment shall comply with all the technical requirements of the present document at all times when operating within the boundary limits of the declared operational environmental profile. For testing the compliance with technical requirements see also EN 301 126-1 [4] and clause 5 of the present document. NOTE: With the generic term of environmental profile, it is here intended any variation of the "external" conditions (e.g. climatic and external primary/secondary power supply sources feeding the equipment to be assessed) that might affect the system parameter relevant to the "essential requirements" of article 3.2 of the R&TTE Directive [1]. 4.2 RF-channel Selection RF-channel selection procedure is mandatory for Class A equipment only.
ETSI ETSI EN 302 217-3 V1.1.3 (2005-03) 11 4.2.1 RF-channel selection procedure The purpose of the RF-channel selection procedure is to detect and protect existing transmissions in order to avoid unacceptable interference situations. At both transmission sites, radio-relay terminals shall measure during installation, the interference levels of both receive and transmit channels (see note). Only in the instance when an unoccupied channel is identified and selected as the transmission channel shall the transmit power be switched on. The interference avoidance requirements for the receiver to detect occupied channels are specified in clause 4.2.2. The principle of protecting existing transmission shall be respected also during the antenna alignment procedure. NOTE: If the national regulatory rules allow to change the frequency of the link during its operation, it may be considered, in order to decrease the possibility of undetected interference, to apply the RF channel selection procedure whenever appropriate (e.g. when restoring a link after a failure or by suitable automatic timed routine in conjunction with frequency agility as in clause 4.2.3). 4.2.2 Interference avoidance requirements 4.2.2.1 Interference avoidance limit The radio relay terminal shall consider the radio channel occupied when the level of the interference is above the following limit: • Pi > C dBm + 10 log (BW/10 MHz). Where: • BW is the noise bandwidth of the receiver expressed in MHz; • Pi is the interference power expressed in dBm measured within the receiver noise bandwidth (BW); The value C is dependent on frequency band and is given in the relevant annex. For the rationale of the interference limit formula see informative annex UD. For test purpose this requirement shall be fulfilled at reference point C within the intended band of transmission: • with a signal similar to the transmitted one; • with a CW signal at any frequency within this band. The value of the intended band of transmission shall be declared by the supplier. 4.2.3 Frequency agile automatic channel selection Frequency agility is an optional feature. If unacceptable interference which exceeds a predetermined duration is observed, an automatic change of RF-channel can be initiated using the RF-channel selection procedure described above. If an automatic RF-channel change facility is implemented a means shall be provided to disable it. Unacceptable interference criteria shall be declared by the supplier (see informative annex UD, clause UD.3). 4.3 Transmitter requirements The specified transmitter characteristics shall be met with the appropriate base band signals applied at one of the reference points X' of figure 1 of EN 302 217-1 [7]. The appropriate base band signals for most common digital interfaces are given in table 1. SIST EN 302 217-3 V1.1.3:2005

When standard interfaces are provided they shall comply with ITU-T standards or other standardized interface declared by the supplier. However, in some applications of these radio relay systems, interface parts may be integrated with other systems and therefore standard interfaces (X, X' reference sections) are not available under these circumstances. In the latter case the radio system assessment shall be made including those other equipment for properly supplying all loading conditions foreseen.
4.3.1 Transmitter power 4.3.1.1 Transmitter power
Transmitter maximum mean output power at reference point C' of the system block diagram (figure 1 of EN 302 217−1 [7],) shall not exceed A dBW (including tolerance and, if applicable, ATPC/RTPC influence). The values of A are dependent on frequency band and are given in the relevant annex(es). 4.3.1.2 Equivalent Isotropically Radiated Power (EIRP) The Equivalent Isotropically Radiated Power (EIRP) shall be limited to +B dBW. The values of B are dependent on frequency band and are given in the relevant annex(es). NOTE: This requirement is for assessment of equipment with integral antenna only; however also equipment placed on the market without antennas should, in principle, when relevant in common practice, refer to such limitations (e.g. defining the maximum associated antenna gain). 4.3.1.3 Output Power Tolerance The power tolerance and the nominal output power shall be declared by the supplier and shall be included in the limits in clauses 4.3.1.1 and 4.3.1.2. 4.3.2 Radio Frequency (RF) spectrum mask The radio frequency spectrum mask is system dependent and is given in the relevant annex. 4.3.3 Spurious emissions - external The limits of spurious emissions (or more precisely, according latest ITU-R definitions, unwanted emissions in the spurious domain), which apply at reference point C', shall conform, in any setting conditions of ATPC and RTPC if any, to: • EN 301 390 [6] when digital equipment is concerned; • CEPT/ECC REC 74-01 [2] when analogue equipment is concerned. NOTE 1: CEPT/ERC/Recommendation 74-01 [2] based on ITU-R Recommendations SM.329 and ITU-R Recommendation F.1191 (see bibliography) gives the applicable definitions. NOTE 2: EN 301 390 [6] includes, for P-P systems, the same limits of CEPT/ERC/Recommendation 74-01 [2]. SIST EN 302 217-3 V1.1.3:2005

ETSI ETSI EN 302 217-3 V1.1.3 (2005-03) 13 4.3.4 Radio frequency tolerance The maximum allowable RF frequency tolerance from the nominal carrier frequencies shall not exceed ±X ppm. This limit includes both short-term factors (environmental effects) and long-term ageing effects. The values are system dependent and are given in the relevant annex(es). The supplier shall declare the values of the nominal carrier frequencies. In the type test the supplier shall state the guaranteed short-term part and the expected ageing part. 4.3.5 Antenna directional requirements This clause is relevant for all equipment specified in annex UA when an integral antenna is provided. Stand alone antenna products are covered, for the relevant frequency band and antenna class, by EN 302 217-4-2 [8]. However, with integral antennas, it may be possible to test the antenna separately from the equipment (see note); in this case the declaration of conformity may be composed of a declaration of conformity for the equipment and a declaration of conformity for the antenna, done separately by the actual supplier(s), according to EN 302 217-4-2 [8].
NOTE: Using special tool supplied by the supplier. 4.3.5.1 Radiation Pattern Envelope (Off-axis EIRP density) In the case of an integral antenna system and where applicable, the radiation pattern envelope (off-axis EIRP density) is essential under article 3.2 of the R&TTE Directive [1]; the clause that gives the limits of this essential phenomenon is clause 4.2 of EN 302 217-4-2 [8]. 4.3.5.2 Antenna gain In the case of an integral antenna system and where applicable, the antenna gain is essential under article 3.2 of the R&TTE Directive [1]; the clause that gives the limits of this essential phenomenon is clause 4.3 of EN 302 217-4-2 [8]. 4.3.5.3 Antenna Cross-Polar Discrimination (XPD) No requirements apply. (cross-polar radiation pattern requirements are not relevant for equipment operating in frequency bands where no frequency co-ordination is applied). 4.4 Receiver requirements 4.4.1 Spurious emissions The limits of spurious emissions (or more precisely, according latest ITU-R definitions, unwanted emissions in the spurious domain), which apply at reference point C, shall conform to: • EN 301 390 [6] when digital equipment is concerned; • CEPT/ECC REC 74-01 [2] when analogue equipment is concerned.

Boundary limits of environmental climatic conditions, which are part of the environmental profile may be determined by the environmental class of the equipment according to the guidance given in clause 4.4 of EN 301 126-1 [4]. Tests defined in the present document shall be carried out at representative points within the boundary limits of the declared operational environmental profile. Any test, requested to generate the test report and/or declaration of conformity in order to fulfil any Conformity assessment procedure with respect to the R&TTE Directive [1] shall be carried-out: a) For radio equipment, with respect to the same principles and procedures, for reference and extreme conditions, set out in clause 4.4 of EN 301 126-1 [4] for climatic conditions and in table 1 of EN 301 126-1 [4] and clauses 5.2 and 5.3 of the present document for power supply conditions. The requirement for test at reference or extreme conditions is set out in clauses 5.2 and 5.3 of the present document according to the principles for similar requirements in EN 301 126-1 [4]. b) For integral DFRS antennas (directional phenomena of claus
