Path Loss, Models, Measurements, Radio Wave, Friis, Okumura-Hata.
Propagation path loss models play an important role in the design of cellular systems to specify key system parameters such as transmission power, frequency, antenna heights, and so on. Several models have been proposed for cellular systems operating in different environments (indoor, outdoor, urban, suburban, and rural). This work sets out to predict the path loss of a UHF channel along three routes in Akure metropolis using existing models (Friis, Okumura-Hata). Broadcast signal field strength measurements were taken across the three routes. Measured values were compared with the different models prediction to determine model suitable for the city. Consequently, a modified Hata’ model was developed which can be deployed by engineers in radio communications system planning and design.
