Characterization of Multipath Composition of Sub-6 GHz and mmWave Channels in an Industrial Scenario Using Ray Tracing Simulations

The integration of fifth-generation networks with Industrial Internet of Things (IIoT) applications is pivotal for fulfilling the technical demands of Industry 4.0, including robust data traffic, minimal latency, and high data throughput. However, deploying these networks requires accurate channel models that capture the unique characteristics of industrial indoor settings. This study addresses this need by presenting a comprehensive characterization of channels at 3.5 GHz, 28 GHz and 73 GHz within an indoor factory (InF) environment through ray tracing simulations. These simulations account for specular reflection, diffraction, and diffuse scattering effects. The analysis encompasses path losses, Rice factor, shadowing, and line-of-sight probability, with a focus on delineating contributions from propagation phenomena.
