Modeling the Local Rainfall Effects on Millimeter-Wave Propagation Using Homogeneous Meteorological Areas

The prediction of rain rate is one of the important topics in analyzing wireless communication systems, particularly in the analysis of broadband satellite links operating in the Ku-band (12-18 GHz), K-band (18-26.5 GHz), and Ka-band (26.5-40 GHz). A perfect physical model for the rain attenuation requires some parameters which are not available in most places on the Earth. This letter shows how to use the climatology skills to recognize homogeneous meteorological areas for two different countries and how to generalize the rain-rate attenuation prediction model of one city to another. The proposed method is then compared with the International Telecommunication Union model and the method of moments to confirm the results.
