Electromagnetic environment characterization of complex environment such as a hospital is a challenging issue due to the dynamic characteristics like field fluctuations over time as well as space, and multiple interference sources within. This paper proposes an alternative perspective on electromagnetic environment characterization depending on Efield probe measurements. A hospital is known to be a semireverberant, and often undermoded environment. For this reason, in this paper, it is considered to be similar in behavior to a vibrating intrinsic reverberation chamber (VIRC), operating in undermoded region. The measurements were performed using 3-axis E-field probes at nine different locations inside a VIRC. It was aimed to characterize the environment using 3-axis E-field probe measurement results by considering the concept of ergodicity. Finally, the probability distributions were observed.
