The authors describe measurements which were performed to characterize shadowing in indoor radio environments. They investigated the suitability of the log-normal shadowing model for indoor mobile and portable radio channels and determined how the parameters of the log-normal shadowing model are dependent on frequency and topography. They show that the correlation coefficient can be completely independent of wavelength over a frequency octave; however, it is highly dependent on the specific topography of the building. Furthermore, they discuss mechanisms for shadowing which explain why the shadowing component is nearly identical for two frequencies in one environment, while in other environments, the shadowing components at two frequencies are virtually independent
