scope:

This Recommendation provides diversity techniques for point-to-point fixed wireless systems. The diversity techniques include those considered in the domain of space, angle, frequency or their combinations. Basic methods for choice of diversity, obtaining or processing the diversity signals are presented in the Annex, which also gives practical diversity effects based on propagation data. Diversity techniques using alternative transmission media or route/site diversity which may be applied to improve system availability are not handled in this Recommendation.
