A Method to Enhance the Bandwidth and Noise Immunity of IIoT When Exposed to Natural and Intentional Electromagnetic Interference

Abstract

The rapidly developing ultra-wideband (UWB) radio technology is very promising for use in infocommunication systems and networks, in particular in wireless, personal (WPAN) and local (WLAN) IoT / IIoT (Internet of Things / Industrial Internet of Things) networks, including and in wearable networks (Wireless Body Area Network, WBAN) for IoMT (Internet of Medical Things). Ensuring high reliability, increasing noise immunity and the degree of information protection from interception in IIoT is due to the use of UWS technology based on ultrashort pulses with a duration of the order of units and fractions of a nanosecond, time pulse modulation and flickering polarization of the emitted signal. The use of UWS technology in a wireless IIoT network provides a number of advantages that cannot be achieved with existing methods. UWS technologies make it possible to provide high speed data transmission, low power consumption of communication facilities, solution of the problem of determining the location of objects with an accuracy of several centimeters, high penetrating power of the radio signal, an almost unlimited number of communication channels and low cost of communication facilities. The aim of the work is to ensure high reliability, noise immunity and the degree of information protection against interception in IIoT critical in speed, reliability and safety under the influence of natural and deliberate electromagnetic interference. The results obtained and the directions for further research are discussed in the conclusions.
