Abstract

Rainfall is the main cause of signal degradation along the communication signal links above 10 GHz frequency. A crucial parameter for accurately determining rain attenuation is the 1-min rainfall integration time which is very scarce. This paper presents a conversion model for Gqeberha in South Africa on a 5-year (2016–2020) rainfall rate from a 60-min integration time to 1 min using three recognized empirical models (Segal, Burgueno, and ITU-R). The root mean square error (RMSE) metric measure has been used to test the performance of the model. The results show that the annual 60-min rainfall rate integration time varies with no significant pattern over the 5-year observation, while compared to other models; the Segal model in this study predicts Gqeberha with greater accuracy based on the lowest RMSE of 10.
