Modern trends in the development of infocommunication systems and networks include the penetration of digital technologies in all spheres of human activity, the increase in the amount of information circulating in telecommunication networks, the expansion of the variety of information sources, the increase in their mobility and the integration of telecommunication systems both at the hardware and software level and at the level of services provided. In this regard, the tasks of ensuring electromagnetic compatibility of various radio interfaces, the solution of which is based on monitoring the congestion of the radio frequency range, are becoming increasingly urgent. The article discusses monitoring issues in wireless networks to identify information systems operating in the “subnoise channel” on the example of IoT networks based on LoRa technology. LoRa uses broadband radio signals, the reception of which can be carried out in the range from 0 to 20 dB below the level, so traditional monitoring tools based on the allocation of “strong” narrow-band radio signals cannot be used to solve the task. |
