Abstract Ultrawideband (UWB) spatio-temporal area propagation measurement and modeling was performed for accurate characterization of spatial UWB channels. The area propagation measurement acquires as much channel data as possible in one specific environment, e.g., in an office room, to characterize the variation of the dominant scattering process against antenna position displacement. The spatio-temporal channel modeling includes propagation path detection, parameter estimation, and path tracking. A simple spatio-temporal beamforming was considered for path detection and parameter estimation. The path tracking is capable of distinguishing meaningful propagation paths from insignificant ones, and also of clustering propagation paths. The modeling results agreed very well with physical scattering processes, and therefore, the method was proven to be reliable.
