Study of Dust Effect on Radio Wave Propagation at Sub-6 GHz in Industrial Environments

Today, 5G wireless communication systems play an important role in the development of the Industry Internet of Things (IIoT). However, when utilizing sub-millimeter or millimeter (mmWave) waves, the existence of scatterers such as dust in the environment can cause additional path loss and may significantly degrade the system performance. In this paper, we present a split-step parabolic equation based model to characterize the effect of dust on radio wave propagation at sub-6 GHz in industrial environments.
