1 Spatial Dynamics of Indoor Radio Wideband Channels

By Dana Porrat, Aawatif Hayar and Yuval Serfaty


Abstract—The multipath components of super-wideband (2-17.2 GHz) 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 multipath components have an approximately log-normal histogram. An analysis of measured channels that explicitly includes finite spatial areas of visibility of the multipath components is superior to the classic analysis that attributes spatial dynamics to interference of the multipath. The spatial stability of measured responses, i.e. the size of the typical area of visibility of each multipath 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. I
