Radio propagation models are focus on realization of the path loss with supplement task of predicting the coverage area for a radio transmitter. Radio propagation models are empirical in nature and are developed based on large collection of data for the specific scenario. This paper is to study of different path loss propagation models in radio communication at different frequency band. Like SUI model, Hata model, Okumura model, COST-231 model, ECC-33 model and W-I model.
