Fixed Radio Systems; Representative values for transmitter power and antenna gain to support inter- and intra-compatibility and sharing analysis; Part 1: Digital point-to-point systems (V1.2.1)
The present document summarizes@ in relation to the various frequency bands and sub-system types given in the multipart EN 302 217 [i.2] to [.i.7]@ information in relation to current practical bounds coming from technology and deployment practice about: ? Typical-maximum TX power (see note). ? Typical-maximum antenna size and gain. ? Exceptional antenna size and gain. NOTE: This should not be intended as the power delivered by equipment currently on the market; it indicates the level that is reasonably achievable by FS technology in each band and might be rendered available standing suitable market opportunities justifying the cost/benefit trade off. Antenna gain is also related to its expected typical antenna size@ which nowadays@ for its ambient impact@ is another important factor limiting@ in practice@ most of FS deployments. The above values are here reported here due to a lack of any ECC harmonized regulations. In the event that such ECC regulations would come into force@ it would supersede any less restrictive information given in the present document. In the band 57 GHz to 64 GHz CEPT promotes an uncoordinated or simplified use of the band as outlined in ECC Recommendation (09)01 [i.9]. Also in the band 64 GHz to 66 GHz ECC Recommendation (05)02 [i.10] provides for simplified channel arrangement suitable for simplified regulatory approach (e.g. light licensing otification). In the bands 71 GHz to 76 GHz and 81 GHz to 86 GHz ECC Recommendation (05)07 [i.11] provides flexible arrangements suitable for both simplified regulatory approach (e.g. light licensing otification) or conventional coordination; CEPT administrations would freely select the approach best fitting their policy for the bands.
