A Study of FR2 Radio Propagation with Focus on Mobility Management in an Industrial Scenario

This work presents the analysis of a measurement campaign performed in a realistic two-hall industrial environment for FR2 band. In order to provide secure, reliable and high available Machine-to-Machine communications in the mmWave band for Industrial Internet of Things mobile applications, a study of the physical propagation channel must be carried out. The analysis shows the high variability of the propagation channel depending on the Line-of-Sight or Non Line-of-Sight condition, with path loss exponents ranging from 2.10 to 4.56. The mobility analysis demonstrates the high probability of beam switching if a threshold is not defined. By imposing this threshold, there is a decrease in the complexity of mobility management in exchange for a reduction in received power at the end user.
