scope:
The present document applies to Multimedia Wireless Systems (MWS) in the band 40,5 GHz to 43,5 GHz, which operate in block assignments, according to ECC Recommendation 01-04 [19]. It includes those parameters considered to be essential under article 3.2 of the Directive1999/5/EC [1], 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". Where equipment is intended for operation other than as specified in ECC/REC. 01-04 [19] there may be additional requirements outside the scope of the present document.
The relevant equipment parameters in EN 301 997-1 [13] are referenced as well as antenna parameters in EN 301 215-3 [3]. These standards also contain other requirements that are not considered essential for the R&TTE Directive, but are nevertheless recommended on a voluntary basis to meet relevant network performance objectives as defined by international standardizing bodies.
A wide range of Multimedia Wireless Systems (MWS) is possible. The present document covers a range of alternatives, for which the access methods and corresponding test requirements are specified in available relevant ETSI standards and referred to in EN 301 997-1 [13]. Similarly, antennas other than those specified in available and relevant ETSI standards may also be proposed.
A range of antenna and equipment types and corresponding test methods are covered by the present document. However, it should be noted that, national regulatory bodies, according to article 7.2 of the Directive [1] may, for the purpose of local licensing, limit the options permitted.
For system variants that do not use the access methods or do not meet the ETSI specified parameters for equipment in EN 301 213-1 [14], EN 301 213-2 [15], EN 301 213-3 [16], EN 301 213-4 [17], EN 301 213-5 [18] or antennas in EN 301 215-1 [2], EN 301 215-3 [3], CE marking may also be possible via one of the alternative routes described in the R&TTE Directive 1999/5/EC [1].
