Human Posture Effects of WBAN Measurement in a Reverberation Chamber

In this paper, the effect of human postures in a wireless body area network (WBAN) measurements in a reverberation chamber is investigated by numerical simulations and statistical analyses. A rotating stirrer and a walking human posture model are assumed in a small size reverberation chamber. Electric field amplitudes at observation points are calculated and the distributions of them are analyzed. As a result of the three-way analysis of variance, it is found that the human posture has a comparative effect on the electric field distribution than that of the stirrer. Also, it is found out that the effect of the observation points becomes large when conducting the measurement with a human model inside the chamber. To perform simulations and analyses with other conditions, to compare the results with measurements are left for further studies.
