摘要：

Rain fall causes drastic attenuation in wireless communication signal including mobile, satellite communication etc. Consequently, there is a substantial requirement to consider rain attenuation to design system for various terrestrial links. This paper contains annual R0.01% rain rate of 30 stations for 31 years around Bangladesh. Using ITU-R prediction model, total rain attenuation is obtained utilizing different time, distance and frequency. Vertical polarization is considered to measure the attenuation due to its less attenuation than horizantal. Moreover, the contour map is designed for different bands (C, Ka and Ku band) for vertical polarization. Furthermore, from the entire contour map, it is also observed that, rain attenuation is the most severe in Teknaf and least in Rajshahi.
