THE STUDY OF THE CHARACTERISTICS OF PROPAGATION OF ELECTROMAGNETIC WAVES IN THE INTERNAL AREAS INDOORS

UDC 621.396

E.S.Zatsepin, A.G.Sklyar, D.V.Rusanov

In the paper we consider the problem of propagation of electromagnetic waves in the internal area of the premises. Based on the analysis of possible approaches to solving this task the experimental method was chosen. The results obtained for different variants of propagation of electromagnetic waves through different environments were obtained. The structure of subsystem of data processing in the study of the propagation of the radio waves in the room was proposed.

Keywords: : wireless communication, experiment, method, optimization, method, coverage, approximation.

THE SIMULATION OF RADIO WAVE PROPAGATION IN MOBILE COMMUNICATION SYSTEMS

UDC 621.396

E.S.Zatsepin, A.G.Sklyar, D.V.Rusanov

In the paper we considering the simulation of the propagation of electromagnetic waves of cellular communication systems in the city. On the basis of the corresponding transmission channel as well as optimization techniques a possible reflections of the rays during propagation along streets are found. The values of attenuation at different distances from mobile base stations are calculated.

Keywords: : communication, simulation, radiation method, optimization, method, coverage area.
