Statistics of rain attenuation revisited [PDF]
2011 XXXth URSI General Assembly and Scientific Symposium, 2011 Millimeter frequency satellite links are prone to variations in attenuation over a large range due to rain, more than 30 dB. Traditionally, it has been considered to be part of meteorological conditions, unavoidable variations. Statistical distributions have been fit-to-data type with little or no physical insight.

Rain Attenuation Prediction for Terrestrial Microwave Link in Bangladesh [PDF]
Journal of Electrical and Electronics Engineering, 2014 Rain attenuation is a major shortcoming of microwave transmission. As a subtropical country, Bangladesh is one of the highest rainy areas of the world. Thus, designing a terrestrial microwave link is a serious challenge to the engineers.

Rain Attenuation at 58 GHz: Prediction versus Long-Term Trial Results
EURASIP Journal on Wireless Communications and Networking, 2007 Electromagnetic wave propagation research in frequency band 58 GHz was started at TESTCOM in Praha due to lack of experimentally obtained results needed for a realistic calculation of quality and availability of point-to-point fixed systems.

Learning-Assisted Rain Attenuation Prediction Models
Applied Sciences, 2020 Rain attenuation becomes significant to degrade the earth-space or terrestrial radio link’s signal-to-noise ratio (SNR). So, to maintain the desired SNR level, with the help of fade mitigation techniques (FMTs), it needs to control transmitted signals ...
