rain attenuation

rain attenuation

[′rān ə‚ten·yə‚wā·shən]
(communications)
Attenuation of radio waves when passing through moisture-bearing cloud formations or areas in which rain is falling; increases with the density of the moisture in the transmission path.

Rain attenuation in satellite communication systems operating at Ka band frequencies is more severe than usually experienced at lower frequency bands [5].
Due to its rain attenuation proportionality properties to range, our short range simulation and measurement results will lead us to estimate the rain effects for longer range as 5G realistic applications.

Rain attenuation becomes the more dominant factor as the higher frequency and should be considered.
Research of seasonal rain attenuation and radio waves fading in LOS links at 19.5 GHz on South Africa terrain are presented in [5].
The previous research of DSD using data obtained from Kuala Lumpur by Lam [17] focused on investigating the dependence of the rain attenuation on the DSD and finding the key raindrop diameter for computing specific rain attenuation, rather than establishing the relationships of DSD in the region with defined equation's fittings and coefficients.
Combining Equations (6) and (7) yields a new equation that obtains the PER according to the rain attenuation values, as expressed in Equation (8).
It should be noted that the most common reference available in calculating rain attenuation often uses rain intensity R, probably because of a scarcity of rain drop size data.
