In the course of research activities in the field of new technologies of information interaction of on-board equipment of objects of rocket-space and aviation equipment, as well as study of protection of information against leakage through technical channels, there was a hypothesis, about stealth of radio channel formed by means of new and promising developing technologies. The article discusses the use of radio wave interference control technologies (on adaptive formation of the sum of the signal phases) for beam formation. The features of the MU-MIMO and OFDMA technologies, which allows several simultaneous outgoing streams (downlink, uplink), providing simultaneous servicing of several devices at once, which increases the performance of the network as a whole, are considered. The implementation of the secrecy of the operation of the radio channel based on the considered technology for potential unauthorized detection of the operation of the radio channel and access to the transmitted information outside the beam pointing points is considered. Based on the description of the technology and on-site experiments, conclusions are drawn and recommendations are formulated on the methodology for detecting unauthorized data transfer implemented on the basis of the technology considered.
