The subject of the study is the processes of ensuring the security of information in wireless control channels and communication of the Internet of Things (IoT). The purpose is to develop the concept of broadband Internet access and to implement key security competencies in the implementation of IoT projects. The model is based on the reference model DigComp 2.0, which was created within the system of digital competence of citizens. Moreover, the main area of competence of this model is safety. The task is to ensure that the IoT system is running smoothly and securely. Methods used: methods of analytical, simulation and temporal position-impulse coding. The following results were obtained. The concept of security in wireless control and communication systems of IoT has been developed. It has been shown that wireless high-bandwidth technology, which enables high volumes and speeds of data transmission, should be used to obtain high noise immunity to control and communication channels and to protect information from interception. The possibility of seamless, one-band operation for both traditional narrowband communication systems and systems that use broadband signals is justified. A technical solution is proposed for the construction of a broadband transceiver antenna system. Conclusions. The use of high bandwidth channels allows for an almost unlimited increase in the number of IoT control channels and communications. Pre-allocation between channels of orthogonal codes implements the process of control and communication without interception of information and interference. Moreover, the use of the temporal position-impulse coding method prevents inter-character distortions of coding short-pulses. This also reduces the level of distortion of information signals caused by its multipath propagation, which guarantees the security of information in the IoT system.
