Statistical characterization of the indoor mobile radio channel at 946 MHz

This paper describes the results of propagation measurements carried out in an office complex at 946 MHz with three objectives: to investigate the impact of desk population on the average propagation loss, to model average path loss, and to fit a statistical description to the measured results. The measurements were conducted on two identically structured floors: one fully occupied and the other completely empty. The loss in the fully occupied floor is found to be marginally higher, but the propagation loss factor is more uniform in different directions from the base. For the populated environment, diffraction calculations were found to show good correlation with the measurements. Fade margin obtained from site measurements was found to be significantly less severe than is predicted from the use of the Rayleigh fading model. The Nakagami fading model fits the results better than the generally accepted model in Rayleigh fading.
