The multipath components of wideband (2-17 GHz) non line of sight channel responses measured inside several buildings are stable along sections that are 9.5 cm long on average with a standard deviation of 8.1 cm. An analysis of measured channels that explicitly includes finite spatial areas of stability of the multipath components is superior to the classic analysis that attributes spatial dynamics to interference of the multipath. The spatial stability of responses with 1 GHz bandwidth decreases as the center frequency increases, i.e. the size of the typical area of stability of each multipath component tends to decrease with increasing carrier frequency.
