Abstract :
In this paper, the measured data and the empirical path loss models for 3.1-10.6 GHz ultra-wideband (UWB) radio propagation in the residential environment for single-band and multi-band communication are presented. The path loss characteristics are demonstrated based on the measured channel for line of sight (LOS) propagation by using the double ridge horn antenna and the biconical antenna to investigate the dependence of the antenna directivity on the UWB system. The characterization of the path loss exponent, n, and the reference path loss, PL(do), are provided. In the case of the single-band propagation, as the results, the path loss increases as the T-R separation distance increases as same as the multi-band propagation. For the case of the multi-band channel, however, the path loss exponent can randomly change according to each propagation scheme and subband frequency. Therefore, the propagation path loss models are developed to understand the phenomenon of the indoor residential communication systems for home wireless networking.
