Abstract

During radio frequency propagation, an interaction between waves and environment attenuates the signal level. It causes path loss and finally limits coverage area. Empirical models are employed in network planning, most especially for conducting feasibility studies. This research work embraces two empirical models: Friis and Okumura-Hata and are used to predict broadcast signal strength for Akure, Ondo State, Nigeria. Measurement results of signal strength in UHF band taken in the three routes of Akure were compared with the predicted results using the empirical models. However, in this research paper, a modified Okumura-Hata model was developed and can be used for radio communication system design in Akure metropolis.
