Limitations of Efficiency of Wireless Systems of Telecommunications 5G and Methods of Their Compensation

Abstract

The article analyzes the approaches to the mathematical modeling of promising telecommunication systems in the millimeter wavelength range. The advantages and limitations of the use of the millimeter wave range are analyzed. It has been proposed in the models for calculating the energy budget of radio channels to take into account the limiting and compensating factors that are characteristic of radio systems in the millimeter range. A comparative analysis of models for calculating the budget of radio lines based on the Friis formula, the quasi-optical model, and the theory of phased antenna arrays is carried out. It is shown that increasing the energy efficiency of telecommunication systems in the millimeter range requires fundamentally new approaches to modeling radio channels.
