ITU-R F.1565-1 PDF

This Recommendation* specifies performance degradation due to interference from other services sharing the same frequency bands on a co-primary basis, or from all other sources of interference, with real digital fixed wireless systems used in the international and national portions of a 27 500 km hypothetical reference path at or above the primary rate. These performance degradations are defined, for each direction of real fixed wireless links, for synchronous digital hierarchy (SDH) systems designed according to Recommendation ITU-T G.828, or for other systems designed according to Recommendation ITU-T G.826.

* The structure and format of this Recommendation may need to be revised in the future to include the detailed technical information from the recommends part to a separate Annex.
