Fixed Radio Systems - Multipoint equipment and antennas - Generic harmonized standard for multipoint digital fixed radio systems and antennas covering the essential requirements under article 3.2 of the Directive 1999/5/EC
The present document applies to the following FDRS types:
1) Multipoint FDRS intended for operation in frequency bands that require co-ordination; this includes both
Point-to-MultiPoint and MultiPoint-to-MultiPoint FDRS;
2) Antennas for multipoint FDRS and antennas for point-to-point FDRS used at the terminal and/or repeater
station of multipoint FDRS systems. These antennas may be either an integral part or may be used as a
standalone part of the equipment (outdoor unit).
For point-to-multipoint equipment operating in the frequency range below 1 GHz the limits of the essential
phenomena off-axis EIRP density, antenna gain and cross-polar discrimination as well as their test methods
may be defined by the notified body according to the R&TTE Directive [1] due to lack of a Harmonized
Standard.
The present document is intended to cover the provisions of Article 3.2 of the R&TTE Directive [1] which states that
"¿.radio equipment shall be so constructed that it effectively uses the spectrum allocated to terrestrial/space
radiocommunications 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] may apply to equipment within the scope of the present
document.
NOTE 1: A list of such ENs is included on the ETSI web site (www.etsi.org).
Table 2 summarizes the ETSI standards applicable to multipoint FDRS referenced in Mandate M/284 [34] from which
the essential requirements within this standard have been extracted.
Those ENs also contain other requirements that even if not considered essential for the R&TTE, are nevertheless
applicable on the ETSI commonly understood voluntary base to guarantee network performance objectives, as defined
by international standardizing bodies, and operability of FDRS.
