Empirical UWB path loss models for typical office environments

This paper investigates the path loss characteristics of an UWB signal (0.1-2 GHz) in a typical office building. Three statistical path loss models are presented, i.e. the n/sup th/ power model and two attenuation factor dependent models. Attenuation factor for brick and gypsum wall, the two main obstructive walls in this experiment were investigated assuming free space path loss. Attenuation factor of 10.37 dB and 3.86 dB were obtained per gypsum and brick wall respectively. A new distance-dependent attenuation model for gypsum and brick wall is also presented. Comparison of the three proposed path loss models is included.
