Abstract

This paper presents an area-segmented adaptive transmission strategy aiming at providing near-uniform high quality coverage in terms of availability and average spectral efficiency across the coverage area in broadband fixed wireless access (BFWA) systems operating at 30 GHz. The strategy considers implementation during rain in tropical regions with heavy rain rates of fixed 64-QAM, adaptive modulation (AM), adaptive coded modulation (ACM) with or without cell-site diversity with selection combining (SC), to be implemented in different ring-shaped segments around each base transceiver station (BTS). The results of synthetic storm-based evaluation show that near-uniform high quality coverage in tropical regions can be achieved using this strategy. Discussions are made upon the implementation of the area segmentation strategy in cellular configurations having square cells with different spacings between BTSs.
