Geo-location databases are ideal for detecting TV white spaces by white space devices (WSD) in the United States (US). The approach protects spectrum incumbent (primary users) and secondary users from interference adequately by keeping a record of the TV transmitters’ information and relying on propagation models to determine the TV transmitters’ protection area. This paper presents statistical path loss models derived from experimental data collected in Benin city, Edo State in Southern Nigeria from Edo Broadcasting Service (EBS), operating at 745.25MHz. The measurements’ results were used to develop a path loss model for the urban areas of Edo state. The measurement results showed that the Path loss increases by 23.1dB per decade in the urban areas. Variations in path loss between the measured and the predicted values from the Okumura-Hata model were calculated by finding the mean square errors (MSE) to be 1.31dB for the urban terrain. These variations (errors) were used to modify the Okumura-Hata models for the terrain. Comparing the modified Hata model with the measured values showed a better result. The developed statistical Path loss models or the modified Hata models can be used in the urban areas of Southern Nigeria.
