Fast Fading Characterization for Body Area Networks in Circular Metallic Indoor Environments

Abstract: With the increasing development of 5G and Body Area Network based systems being implemented in unusual environments, propagation inside metallic structures is a key aspect to characterize propagation effects inside ships and other similar environments, mostly composed of metallic walls. In this paper, indoor propagation inside circular metallic structures is addressed and fast fading statistical distributions parameters are obtained from simulation, being assessed with measurements at 2.45 GHz in a passenger f… Show more

“…The signal at the Rx can be described by the sum of the LoS component with the reflected ones; many reflections are observed, their importance decreasing for an increasing reflection order, due to the increasing path length and the corresponding increasing attenuation. Regions with a given number of reflections are defined as catacaustic zones [18], [19, p. 183-186], Figure 2 showing the catacaustic regions for different Rx positions, when 1 st and 2 nd order reflections are considered: 2 or 4 reflections are observed for 1 st order reflections, while for 2 nd order ones, one can see that there are up to 8, [14]. When analyzing the sum of the reflection components, one can consider up to Nr order reflections, with reflected rays in each one, hence, the signal at the Rx is described by [14],…”

“…Moreover, among other aspects, the scenario dynamics, namely due to the presence of people and obstacles, the use of different types of antennas/polarizations and the user's body movement (causing antennas misalignment), will also have an impact on results. Still, among all these limitations, the proposed model allows to reasonably match the results from measurements for the conditions under study [14]. The three-dimensional approach is left for future work.…”
