Fixed Radio Systems; Characteristics and requirements for point-to-point equipment and antennas; Part 4-2: Antennas; Harmonized EN covering the essential requirements of article 3.2 of the R&TTE Directive (V1.5.1)
"The present document is intended to cover the provisions of Directive 1999/5/EC [1] (RTTE 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 is applicable only to antenna types that are intended for use with the systems falling within the scope of documents EN 302 217-2-2 [i.2] and EN 302 217-3 [i.3]. 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 RTTE Directive 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 302 217-2-2 [i.2]@ 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 Recommendation); ? spectral efficiency class alternatives (different complexity of modulation formats provided in radio equipment standards); ? antenna directivity class alternatives (for different network density requirement). 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@ in EN 302 217-2-2 [i.2] and in EN 302 217-3 [i.3] apply; the present document applies@ as well@ to separate antenna products@ to which only the relevant technical requirements apply. For more background information on the equipment and antenna parameters relevant to article 3.2 of the RTTE Directive see EG 201 399 [i.4] and TR 101 506 [i.6]."
