In a world increasingly focused on the wireless interconnection of devices, it is pertinent to carry out an in-depth investigation of the theory surrounding electromagnetic waves and their propagation mechanisms; only in this way it is possible to carry out an adequate characterization. After the research established as a fundamental basis, two measurement campaigns were carried out in semi-industrial indoor environments, selecting two frequency bands: 2.4GHz and 28GHz, both found within the two frequency sets that comprise the 5G networks to subsequently perform an analysis of the data collected and adjust them to the single-frequency floating-intercept path loss model. The application of the empirical model fits the collected data and shows reliability to predict the path loss behavior for both frequency bands; however, specific studies must be carried out to analyze in detail the specific contributions of the propagation mechanisms. The model proves not to be deterministic, but instead presents random variables and must be approached stochastically, in addition to being highly dependent on the analyzed site.
