This paper contains measured data and empirical models for 3.1-10.6-GHz radio propagation path loss and aggregate penetration loss (APL) in residential areas for UWB applications. A frequency domain based experiment is performed for line-of-sight (LOS) and obstruction propagation conditions. The double ridge horn antenna and the biconical antenna are used to investigate the dependence of the antenna directivity on the UWB path loss. While the penetration loss is modeled under the directional propagation scheme. The characterization of the path loss exponent, n, and the APL are investigated. Therefore, the propagation prediction models are developed to understand the phenomenon of the futuristic indoor residential communication systems for home wireless networking.

UWB system is the one type of several wireless communication that can be used in home networking, which have any probably obstruct by building material. Then the influences of the obstructions are considered. In this paper, the time dispersion and penetration loss are studied. The glass, gypsum, dry wood and partition board are considered the obstruction materials. The channels with these materials are measured in a fully anechoic chamber by using the vector network analyzer. The measurement frequency range is set to be 3-11 GHz, which covered the full band of UWB specified by FCC. The biconical antennas are used for both transmitter and receiver. The time dispersion and penetration loss for each material are evaluated based on the measurement channels. The data of theses results is useful for considering the UWB link budget.

UWB technology is intended to be used in wireless personal area networks and home networking, which has any probably obstruct by building material. Then, the influences of the obstructions on UWB pulse are considered. In this paper, the power delay profile, the time dispersion and penetration loss are considered.
