1 Scope The present document specifies the minimum performance requirements for terrestrial fixed service radiocommunications equipment operating in the 58 GHz frequency band which do not require co-ordinated frequency planning. The frequency band is proposed to be used by various technologies for uncoordinated use of the band. It also benefits from the high and stable atmospheric attenuation which suppresses efficiently distant interferers (about 10 dB/km to 15 dB/km at sea level, refer to ITU-R Recommendation P.676 [17]). For the purposes of the present document two equipment classes are specified depending on the network requirements: - Class A: Digital equipment for High Density Fixed Service (HDFS) applications typically connected to public networks, which apply the RF-channel selection procedure (see clause 4.1.3), error performance and availability requirements (see clause 5.2). - Class B: Equipment without requirements for quality of service, typically private network connections. Typical applications for Class A equipment are e.g. interconnection between cellular networks where there, in some cases, is a need for short length connections (up to about 500 meters). The RF channel selection procedure shall be used to protect existing systems from a new system being commissioned. However, the channel selection procedure may not guarantee interference free installation or operation in all cases due to limitations in the procedure with respect to the variety of systems. Typical applications for Class B equipment are in private networks, such as video surveillance systems. This new version of this EN, introduces a different spectrum mask for systems designed for 50 MHz channel separation. While considered more convenient from the point of view of easy and cost effective design, the new mask is considered equivalent to the previous one from the point of view of spectrum efficient usage. Therefore, from the technical point of view, for compliance to article 3.2 of R&TTE Directive [19], systems that have already been assessed against the previous version of the present document should not be necessarily reassessed against this new version. The present document does not contain aspects related to test procedures and test conditions, however they are to be found in EN 301 126-1 [7]. Safety aspects are outside the mandate of ETSI and they will not be considered in the present document. However compliance to EN 60950 [18] will be required to comply with Directive 1999/5/EC [19]. Technical background for the parameters and requirements referred in the present document may be found in TR 101 036-1 [16]. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. • References are either specific (identified by date of publication and/or edition number or version number) or non-specific. • For a specific reference, subsequent revisions do not apply. • For a non-specific reference, the latest version applies.
