Abstract

This paper describes a study on path loss variation in UHF/VHF bands in India from a root mean square error perspective. The aim of this study is to compare existing propagation path loss models in various parts of India. We calculate average root mean square error (RMSE) between measured path loss and those predicted by the existing path loss models. It is found that Perez-Vega and Zamanillo model is best among the 9 compared path loss models with an average RMSE of 16.93 dB. We conclude that Perez-Vega and Zamanillo model is better suited for predicting path loss in UHF/VHF bands for India.
