description: The subject of the graduate qualification work is "Software modeling of a sys-tem for ultra-mass machine-to-machine data exchange in 5G networks". The main thing of research is noise immunity at different modulations of dif-ferent distances from base stations. This work is devoted to the study and analysis of the standards of modern mobile communication of the fifth generation, the Massive MIMO system used in them, as well as the areas of services used by these technolo-gies. Based on the latest publications, current developments were considered, as well as the problems indicated with this topic, a software model of the communication channel in the SIMULINK environment was compiled. Using the WINNER II exten-sion system, signals were transmitted to the MIMO-OFDM 2x2 input. As a result, the curves of noise immunity of signals were obtained at various modulations, such as 16-QAM, 64-QAM, 256-QAM, 8PSK and QPSK. Based on the results of the work done, it was concluded that it was transmitted from a mobile station located in the 8-dimensional equivalent of the station by a fast method of quick call QPSK modulation. Also, for an antenna located at a distance of 20 meters from this station, this type of modulation is a 64-QAM module. The data obtained can be used as a basis for further conditions for creating digital double ex-change, expanding the model to meet the requirements of ultra-mass machine-to-machine exchange.
