Propagation Measurements and Pertinency of Models for Communications Systems in Oman

This article discusses the usefulness of Okumura-Hata model and Sakagami model in urban areas for 2G and 3G communication systems. At some places, applicability of the models (Okumura Hata and Extended Sakagami) is studied and extended to a much lower distance from the tower than the specified minimum distance indicated in the model. Authors did an extensive drive test in urban areas and post also processed data and proposed theoretical modified model which is presented and compared for different data sets at different locations in Oman. Higher order interpolating polynomial was also used which helps in reasonable prediction for RF engineers.
