Fixed Radio Systems; Characteristics and requirements for point-to-point equipment and antennas; Part 1: Overview@ common characteristics and system-dependent requirements (V3.0.5)
"The present document applies to the following digital fixed radio systems (DFRS)@ including equipment with integral antenna and other antenna types relevant to: ? point-to-point systems intended for operation in frequency bands that require co-ordination; ? point-to-point systems intended for operation in frequency bands that do not require co-ordination; ? antennas for point-to-point operation. The present document summarizes: ? all characteristics@ principles and@ of utmost importance@ terms and definitions that are common to all P-P equipment and antennas and its consultation is necessary when using all other parts of ETSI EN 302 217 series; ? all system-dependent requirements for Point-to-Point (P-P) equipment in applications deployed in bands where frequency co-ordination is generally applied. These requirements are introduced in two different clauses sub-sets: - Main requirements are requirements that are also related to the ""essential requirements"" under article 3.2 of Directive 2014/53/EU [i.1] and further detailed in the Harmonised Standard ETSI EN 302 217-2 [18]. - Complementary requirements are requirements that are not related to essential requirements under article 3.2 of Directive 2014/53/EU [i.1]. Nevertheless they have been commonly agreed for proper system operation and deployment when specific deployment conditions or compatibility requirements are present. Compliance to all or some of these requirements is left to manufacturer decision. Description and limits for parameters relevant to essential requirements under article 3.2 of Directive 2014/53/EU [i.1] are given in the Harmonised Standard ETSI EN 302 217-2 [18]. ETSI EN 302 217-4 [19] provides the antenna characteristics to be used@ in all operating bands@ by any P-P system with integral antennas when assessed under article 3.2 of Directive 2014/53/EU [i.1]. It constitutes also the reference for the equipment manufacturer for developing dedicated antennas and may be used as reference characteristics in the user instruction of equipment supplied without antenna so that the equipment can be operated as intended (e.g. according article10 recital 8 of Directive 2014/53/EU [i.1]) with a stand-alone antenna. As the maximum transmission rate in a given bandwidth depends on system spectral efficiency@ equipment are subdivided in different spectral efficiency classes as defined in ETSI EN 302 217-2 [18]. The spectral efficiency classes are indicative only and do not imply any constraint to the actual modulation format@ provided that all the requirements in the relevant parts of this multi-part deliverable for the declared class are met. Guidance on the definition of radio parameters relevant to the essential requirements under article 3.2 of Directive 2014/53/EU [i.1] for DFRS may be found in ETSI TR 101 506 [i.16]. Technical background for most of the parameters and requirements referred to in this multi-part deliverable may be found in ETSI TR 101 036-1 [i.15]. Health and safety requirements@ relevant to article 3.1a of Directive 2014/53/EU [i.1] are not considered in any part of this ETSI EN 302 217 series. CENELEC is responsible for the relevant standards. EMC conditions and requirements@ relevant to article 3.1b of Directive 2014/53/EU [i.1] and any other essential requirement relevant to article 3.3 of Directive 2014/53/EU [i.1] are not in the scope of any part of this ETSI EN 302 217 series. EMC requirements may be found in ETSI EN 301 489-1 [i.10] and ETSI EN 301 489-4 [i.11]. NOTE: A list of such harmonised standards is available on the web site http://www.newapproach.org. For administration's guidance when notifying their regulated interfaces in accordance with article 8 of Directive 2014/53/EU [i.1]@ annex B provides explanatory considerations on the applicability of the TCAM-RIS format for P-P fixed links. An example of such a notification is also provided. Annex B has been elaborated in co-ordination with the CEPT ECC WGSE."
