Frequency and Bandwidth Dependency of UWB Propagation Channels

In this paper, based on indoor ultra-wide band (UWB) propagation channel measurements for both LOS and NLOS scenarios, the frequency dependency of propagation in the 3-10 GHz UWB range is investigated by examining the power delay profile, rms delay spread, path loss and shadowing as functions of frequency. Moreover, the bandwidth dependency of channel parameters is also investigated for gaining more understanding of the general channel properties
