Analysis of Propagation Models for Base Station Antenna : A Case Study of Ado-Ekiti , Nigeria

Path loss analysis using key parameters and mathematical models is essential for accurate characterization of a radio channel for a coverage area. It plays a fundamental role in predicting the radio coverage, path-loss, death zone and designing of an optimized fixed and mobile network systems. This paper analysed and compared two models, Okumura and Okumura Hata on the basis of variation in antenna height and operational frequency of a base transmitting station (BTS) in Ado-Ekiti, Nigeria. The result obtained shows that Okumura Hata model has a better signal strength delivery to destination with a less reduced path loss variation compared to Okumura model. Even though there is significant gain of about 12dB when Okumura model parameters was varied it is not better than the signal strength Okumura Hata model will deliver to a destination.
