Abstract

This paper presents the results of Ultra Wide Band (UWB) channel measurements for Wireless Personal Area Networks (WPAN). A time domain measurement setup has been developed covering the frequency band from 2.1 GHz. Relevant scenarios for WPAN applications have been proposed and measurements have been conducted in an office at very short distances including both LOS and NLOS cases. Additional NLOS measurements with a human body obstructing the direct path have also been performed to determine the effects of the body on teh UWB-WPAN channel characteristics. In addition to this, the near field effect between transmit and receive antenna has been examined and channel parameters such as root-mean-square (RMS) delay spread, Ricean K-factor and path-loss exponent are obtained. These results can be used for analysis and design of UWB systems for WPAN applications.
