Abstract: One of the major problems associated with the development of the fifth generation in telecommunications systems is the development of radio propagation models operating in mm waves (the frequency spectrum beyond 6 GHz). In this study, different types of channels were studied and evaluated at different values of frequencies. The 3rd Generation Partnership Project (3GPP) TR 38.900 (Release 14) path loss model and Close-In (CI) path loss model, Stanford University Interim (SUI) path loss model are studied and compared both LOS and NLOS environment are investigated to analyze. These results were based on large-scale results and beam tracking across multiple frequencies ranging from 0-100 GHz. This document describes the different channel models including) typical microcell and macrocell propagation scenarios for urban areas) a basic model for integrating path loss, shadow fading for the typical scenarios. This research demonstrates that the 3GPP Model is accurate and stable for the NLOS state and it is independent of the frequencies beyond the first meter of propagation to the LOS environment. SUI Model found to be more accurate and relevant to the LOS environment, followed it CI Model.
