ABSTRACT
This paper is aimed at determining the performance of the renowned Okumura and Hata propagation models for propagation path loss prediction in the City of Warri, Delta state region of Nigeria. The work was carried out through a quantitative measurement of the signal strength of Delta Broadcasting Service which transmits TV signals in the ultra high frequency band at a frequency of 636MHz. The results obtained using the root mean square error RMSE performance metrics shows that the Hata propagation model gave a better pathloss prediction compared to the measured pathloss even though some modification are still required to enable it explain for the pathloss situation in the city of Warri, Delta State Nigeria.
