Summary:The vast array of wireless device form factors being developed for internet-of-things applications necessitates a flexible test environment for determining performance metrics such as total isotropic sensitivity. Reverberation chambers loaded with lossy absorbers at cellular frequencies are an ideal match for this need. However, the estimate of total isotropic sensitivity from measurements in the reverberation chamber depends on the amount of loading in the chamber and on the choice of statistical averaging used in the measurements. We present results showing the significance of these two variables.
