Statistical Modeling of WBAN channels in Indoor Environments Based on Measurements and Ray Tracing

In this article, we assess the influence of the indoor environment on the on-body channel for three radio links of Wireless Body Area Networks (WBAN). The purpose is to realize an analysis and statistical modeling with a large number of samples of premises and locations of subject within rooms. To avoid time consuming with experimentations, the adopted approach is to combine measurements, electromagnetic simulations and data (Channel Transfer Functions) from a simplified Ray Tracing (RT) code. The measurements realized in Anechoic Chamber enable to validate the EM simulations (which can cover a wider range of elevations). The RT code allows to sample with great flexibility a huge number of environments and subject positions within rooms with significant Experimental Designs.
