“…It is important to point out this work, with or without contour maps, follows other similar studies developed in other countries, for example, Colombia [12], Nigeria [13], South Africa [14], India [15], Bangladesh [16], Brazil [17], and Libya [18], among others.…”

Predicting precipitation rate and rainfall attenuation are key aspects in planning and dimensioning of wireless communications systems operating at frequencies above 10 GHz, such as satellite communication systems at Ku and Ka bands. In this paper, contour maps of rainfall rate and rain attenuation are developed for the first time in Venezuela, based on 1-min rain rate statistics obtained from measurements carried out in Venezuela over at least 30 years period with a higher integration time and using Rice-Holmberg model, refined Moupfouma-Martin model and Recommendation ITU-R P.837-7, for rain rate estimation and Recommendation ITU-R P.618-13, Ramachandran-Kumar model, Yeo-Lee-Ong model and Rakshit-Adhikari-Maitra model, for rain attenuation prediction in “Simon Bolivar” satellite links in Venezuela. The overall results of both types of maps represent a useful tool for preliminary planning of those links in the country, specifically, in Ku and Ka bands

“…In this work, to calculate the 1-min rain rate from yearlybased data, Chebil model [15] was used. "Contour map" of rain rate distribution above 0.01 percent of an average year at the C, and the Ku frequency band using ITU-R P.837-6 model [20] is reported in [21]. In this study, the rain rate from Bangladesh agricultural research council (BARC) and the meteorological department were used to develop the "contour map.…”

“…[19] Predicted rain attenuation all over Bangladesh by sectoring the whole country into eight parts for Ku and Ka bands. [21] Developed a "contour map" of rain rate distribution above 0.01 percent of an average year. [22] Predicted the rain attenuation for two probable earth stations of the Bangabandhu-1 satellite at Gazipur and Rangamati for vertical and horizontal polarization using ITU-R P.837-6 model [20].…”

The demands of shifting to the operating frequency of wireless telecommunication systems at new higher frequency bands increase as day by day the necessity to transfer more data volume through wireless networks. Bangladesh has launched its first satel-lite, Bangabandhu-1, with 40 communication channels in the C and Ku frequency bands. Besides, a huge volume of terrestrial microwave backbone networks suffer from fading during rain across the country. Bangladesh experiences heavy rainfall in June-July-August. The rain has a remarkable impact on deteriorating the signal-to-noise ratio at the receiver end. To implement the 5G network, 2.6–60 GHz frequency bands are promising. However, the propagated waves in these bands are prone to fadedue to rain. Unfortunately, the rain attenuation model developed for other climatic conditions can not be used readily without customization. In this regard, to maintain quality telecommunication networks, proper rain attenuation model development is crucial. This work reviews rain attenuation research in Bangladesh, global research trends and the research scope to manage rain attenuation.
