“…The universal power-law model used to describe the rain attenuation and specific attenuation are provided in Equations ( 6) and (7). The relationship between the path length (L p ) and the path reduction factor (r) is also provided in Equation (29). The power-law parameters a and b can be derived using the following Equations ( 73) and (74):…”

“…As described earlier, Equations ( 6), ( 7), (29), and ( 73)-( 75) provide detailed relationships of specific attenuation (dB/km) due to rainfall across terrestrial communication channels and also the relationship between the specific attenuation and rainfall rate, frequency, and polarization characteristics.…”

“…The mmWave band offers the security of communication transmissions and supports the large bandwidth required to provide higher data rates for fronthaul, backhaul and short building-to-building links [2,[19][20][21][22]. However, the major drawback of the millimeter wave signal is its inability to travel over a long distance due to its susceptibility to attenuation by various atmospheric phenomena such as rain, foliage, and other atmospheric absorption [23][24][25][26][27][28][29][30].…”

Radio waves are attenuated by atmospheric phenomena such as snow, rain, dust, clouds, and ice, which absorb radio signals. Signal attenuation becomes more severe at extremely high frequencies, usually above 10 GHz. In typical equatorial and tropical locations, rain attenuation is more prevalent. Some established research works have attempted to provide state-of-the-art reviews on modeling and analysis of rain attenuation in the context of extremely high frequencies. However, the existing review works conducted over three decades (1990 to 2022), have not adequately provided comprehensive taxonomies for each method of rain attenuation modeling to expose the trends and possible future research directions. Also, taxonomies of the methods of model validation and regional developmental efforts on rain attenuation modeling have not been explicitly highlighted in the literature. To address these gaps, this paper conducted an extensive literature survey on rain attenuation modeling, methods of analyses, and model validation techniques, leveraging the ITU-R regional categorizations. Specifically, taxonomies in different rain attenuation modeling and analysis areas are extensively discussed. Key findings from the detailed survey have shown that many open research questions, challenges, and applications could open up new research frontiers, leading to novel findings in rain attenuation. Finally, this study is expected to be reference material for the design and analysis of rain attenuation.
