Effects of Rain Attenuation on 28-30GHz Bands for Beyond 4G Terrestrial Mobile Communications

摘要

The telecommunication community is driven to find new frequency above 10 GHz because of exponential increase in user demands for higher data capacity which means higher bandwidth. Rain attenuation is very significant at frequency bands of 28-30 GHz. The USM-UKM model proposes an accurate rain attenuation prediction at frequency bands between 12-13 GHz. This paper proposes a simple enhancement of the USM-UKM model in predicting rain attenuation in equatorial countries like Malaysia in the 28-30GHz band. Simulation results showed that the proposed 2830-Model predicts a rain attenuation that is higher than ITU-R P.530-15 model by 13dB in the 28-30GHz band. The proposed model is recommended for estimation of rain attenuation at 28-30GHz in equatorial countries due to the better accuracy in rain height.
