Channel Parameters Extraction: A Comparison Between Reference And Real Industrial Scenarios

This paper assesses the channel characteristics in an industrial setting for Industrial IoT (IIoT) applications, comparing elementary reference scenarios with real plants, like those of Robopac-Aetna Group and the Bi-Rex pilot line in Italy. Signal propagation inside the facilities is simulated using 3DScat, a ray tracing (RT) tool. The work focuses on the extrapolation of the major large-scale channel parameters, such as the path loss exponent (PLE) and the standard deviation of shadowing, for base station (BS)-to-node and node-to-node communications at sub-6 GHz, mmWaves, and THz frequencies. Results prove that, despite their differing characteristics, the investigated scenarios exhibit similar trends in terms of PLE and shadowing standard deviation as the operating frequency and transmitter height are varied.
