Communication at higher frequency bands has numerous benefits but susceptible to rain impairments. Rain-induced attenuation becomes more prominent as the carrier frequency and rain rate increase. Hence, precise knowledge of rain rate can help in predicting the level of rain-induced attenuation. The paper determines point cumulative rainfall rate at 0.1% of time exceedance and converts integration time from 5 min to 1 min. The specific and the total rain-induced attenuation were predicted at 0.1% of time exceedance from 12 GHz to 18 GHz for both horizontal and vertical polarizations. Lavergnat-Gole rain rate conversion model and ITU-R P.838-3 model were employed using four-year rainfall data obtained from Port Harcourt, Nigeria. The results revealed that the peak activities of rainfall rates were recorded at lower integration times, and the total rain-induced attenuation increases with increasing operating frequencies, which is greater for horizontally polarized waves compared to vertically polarized waves.
All forms of wireless communication make use of electromagnetic wave, which is
either propagated vertically, horizontally or as a combination of both. Wireless
communication provides huge opportunity to get possible access to the world at
any time in any place without being physically present (Maniewicz, 2019). The
modern-day digital information and wireless communication system are reliant on
radio waves for its transmission (Jianping et al., 2008). Radio wave ranges from the
Very Low Frequency (VLF) to the Extremely High Frequency (EHF) (IEEE, 2002).
Transmission of wireless information at the lower frequency bands is however
associated with long wavelength but very little bandwidth. On the other hand,
