A Study on the Rain Attenuation Prediction Model for Ubiquitous Computing Environments in Korea
In this paper, I present the results of the measurements of rain-induced attenuation in the vertically polarized signal propagating at 12.25GHz during certain rain events, which occurred in the rainy wet season of the year 2001 at Yong-in, Korea (ITU-R rain zone K). The total experimentally measured attenuation over the link path was measured experimentally has been compared with that obtained using the International Telecommunication Union Radio Communication Sector (ITU-R) model. I also propose a prediction model which can predict the rain attenuation in satellite-earth communication links more conveniently and efficiently, by using the 1-h rain rate without conversion.
