Geo-spatial distribution of radio refractivity and the influence of fade depth on microwave propagation signals over Nigeria

July-September, 2023 - Vol 18 Num. 3

The need for more bandwidth for a broad range of purposes necessitates research into how radio refractivity, multipath fading, and geoclimatic variables affect terrestrial and satellite propagation links. In this study, a geographical distribution approach to radio refractivity and fade depth over five locations in...
