Annotation of standard text ČSN ETSI EN 302217-2-V3.4.1 (878595):

V3.4.1
The present document specifies technical characteristics and methods of measurements for Point-to-point (P-P) Digital Fixed Radio Systems (DFRS) operating in frequency bands allocated to Fixed Service (FS) from 1 GHz to 174,8 GHz, corresponding to the appropriate frequency bands from 1,4 GHz to 174,8 GHz as described in relevant annexes B through L.
Systems in the scope of the present document are generally intended to operate in full Frequency Division Duplex (FDD) and cover also unidirectional links applications. Time Division Duplex (TDD) applications, when possibly applicable in a specific band, are explicitly mentioned as appropriate in the relevant annexes B through L.
Other possible prescriptions, limitations and requirements, for operation in specific bands are also explicitly mentioned, as appropriate, in the relevant annexes B through L.
Systems in the scope of the present document are intended to operate only in combination with directive fixed gain antennas respecting the technical requirements in ETSI EN 302 217-4 [6]. Systems in the scope of the present document may be composed by equipment without antennas (see informative annex Q for background) or equipment including integral (but physically detachable) or dedicated antenna.
Systems including integral antennas physically undetachable from the radio equipment are not in the scope of the present document (see note 1).
NOTE 1 - For additional information, the rationale is that the present document as well as ETSI EN 301 126-1 [1] (radio equipment parameters testing) do not provide radiated test methods and ETSI EN 301 126-3-1 [2] (antenna parameters testing) does not provide test methods for undetachable antennas; future revisions could fill this vacancy.
NOTE 2 - The relationship between the present document and the essential requirements of article 3.2 of Directive 2014/53/EU [i.1] is given in annex A
