Fixed Radio Systems. Characteristics and requirements for point-to-point equipment and antennas. Part 2-2: Digital systems operating in frequency bands where frequency co-ordination is applied. Harmonized EN covering the essential requirements of article 3.2 of the R&TTE Directive

Alkalmazási terület

1.1 General background The present document specifies the essential requirements for point-to-point Digital Fixed Radio Systems (DFRS) operating in frequency division full duplex (FDD) in frequency bands, where co-ordinated link-by-link frequency planning is applied. It is intended to cover the provisions of the R&TTE Directive [1] 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". 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. For the correct understanding and application of the requirements in the present document, the definitions summarized in EN 302 217-1 [6] are also relevant. 1.2 Spectral efficiency classes As the maximum transmission rate in a given bandwidth depends on system spectral efficiency, different equipment classes are here defined. They are based on typical modulation formats and limited by a "minimum Radio Interface Capacity density" (Mbit/s/MHz) shown in table 0. Radio Interface Capacity (RIC) is defined in EN 302 217-1 [6]. The minimum RIC density figures in table 0 are valid only for systems operating on the most common channel separation (CS) equal or higher than 1,75 MHz and taking into account that for channel separations "about" 14 MHz (i.e. from 13,75 MHz to 15,0 MHz), "about" 28 MHz (i.e. from 27,5 MHz to 30 MHz), "about" 56 MHz (i.e. from 55 MHz to 60 MHz) and "about" 112 MHz (i.e. 110 MHz or 112 MHz) the RIC density of actual systems is evaluated only over the "nominal" 14 MHz, 28 MHz, 56 MHz and 112 MHz channel width. Minimum RIC figures for some systems operating on 40 MHz channel separation, with RIC density lower than the minimum requirement in table 0, are defined only in annexes C and Ea. For the special cases of sub-STM-0 capacities (defined in Recommendation ITU-T G.708 [i.63], annex D), alternative minimum RIC figures are not defined. Táblázat All classes up to class 4H, for any CS, and classes 5L, 5H, 6L, 6H, 7 and 8, for CS < 27,5 MHz, are intended suitable for ACCP operation and, in principle, whenever appropriate, also expandable to CCDP. Classes 5L, 5H, 6L, 6H, 7 and 8, only for CS ? 27,5 MHz, are further subdivided in two sub-classes: • subClass A: classes 5LA, 5HA, 6LA, 6HA, 7A and 8A are intended suitable, on the same route, for cross-polar adjacent channel (ACAP) operation only (see figure 2a). • subClass B: classes 5LB, 5HB, 6LB, 6HB, 7B and 8B are suitable, on the same route, for ACCP operation and, in principle, whenever appropriate, also expandable to CCDP (see figure 2a). The above classes are for system identification only and will not imply any constraint to the actual modulation format, provided that all the requirements of the selected class in the relevant parts of EN 302 217 series are met. 1.3 System alternatives 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 a number of 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 or Recommendation ITU-R); • spectral efficiency class alternatives (different modulation formats provided in radio equipment standards) as defined in clause 1.2; actual equipment may operate within one spectral efficiency class only (Single-mode) or within multiple classes, either with static pre-selection of the class (Preset-mode) or with dynamic variation of capacity according the propagation conditions (Mixed-mode) (see note); • antenna directivity class alternatives (for different network requirements). NOTE: Single- mode, Preset-mode and Mixed-mode systems are defined in clause 3.1 of EN 302 217-1 [6]; additional information on Mixed-mode systems may be found in annex I of the present document and in TR 103 103 [i.35]. 1.4 Channel arrangements and utilization 1.5 Payload flexibility 1.6 Document structure
