Effective rain rate model for analysing overestimated rain fade in short millimetre-wave terrestrial links due to distance factor by Asma Ali Budalal, Ibraheem Shayea, Md. Rafiqul Islam, Jafri Din, Abdulsamad Ebrahim Yahya, Yousef Ibrahim Daradkeh, Marwan Hadri Azmi

“…One aspect that may partially justify this significant increase in Reff is the fact that the ITU-R P.838-3 model does not consider the impact of the raindrop size distribution (DSD)for tropical climates when predicting rain attenuation at a short-range mm-wave link. …”
