Modeling, Estimation and Experimentation for Radio-wave Propagation for Optimizing Opex and Capex in NG Networks

Abstract

This paper presents results of different propagation mechanisms that occurs when radio waves propagates under different atmospheric conditions with changing temperature, pressure etc. The simulated results were investigated in terms of the refractivity profiles to conclude impact of the interference on signal strength and hence to optimize Opex and Capex in next generation communication networks. The dramatic effect occurring on radio wave propagation due to these variations in atmospheric parameters is resulting refraction which is now-a-days a major concern for the designers/operators of 5G and others terrestrial communications and radar systems. Different atmospheric refractivity profiles are fed into the model of parabolic equation method to estimate simulated transmitted field. The modelled results are validated by the real world experimental results. In order to avail the target set in this research, different propagation mechanisms were investigated. The significance of these propagation mechanisms were very much clear during certain period of time where the signal completely missed its target. The occurrence of complete communication breakdown is not viable during this period and hence these results may be very helpful for the designers/operations of next generation networks.
