Spatial Dynamics of Indoor Radio Wideband Channels

The multi-path components of super-wideband (2-17.2GHz) non-line-of-sight channel responses measured inside several buildings are stable along sections that are 27 cm long on average with a standard deviation of 16 cm. The stability regions of multi-path components have an approximately log-normal histogram. An analysis of measured channels that explicitly includes finite spatial areas of visibility of the multi-path components is superior to the classic analysis that attributes spatial dynamics to interference of the multi-path. The spatial stability of measured responses, that is, the size of the typical area of visibility of each multi-path component, decreases as the carrier frequency increases but does not depend on bandwidth. The results offer insight into the nature of the diffuse part of the radio channel.
