Study of rain attenuation effects for 5G Mm‐wave cellular communication in tropical location

Abstract

Millimetre (mm)‐wave communication is a viable solution to the future 5G cellular services. For different temperate locations, rain attenuation does not contribute significantly to the overall path loss at the mm‐wave band for a small cell size of 200 m. However, in various tropical locations, the rain attenuation effect cannot be ignored even for this small cell size of the system. If the authors increase either frequency or path length, the attenuation increases significantly under tropical raining conditions. In this study, time series of predicted rain rate values are used for real‐time prediction of rain attenuation over terrestrial paths.
