Summary:
This paper presents the experimental study undertaken in order to characterize wired UWB transmission over conventional household powerline. Powerline cables have long been used for low data rate (in the order of few hundred Kbits/s) narrow-band transmission for control and supervision services. High data rate broadband communications would enable effortless in-home networking given the availability of power cables in homes. Although research has been done for frequencies up to 30MHz, the increasing requirements on high transmission data-rates for in-home networking such as high definition video streaming make the utilization of higher frequency ranges necessary [1]. UWB technology maps information in very short bursts of pulses, which are followed by a guard time to cope with channel dispersion. This results in a very high data rate over the available bandwidth. Wired UWB is a viable approach to resolve the limited transmission rates of powerlines. Encouraging results on UWB pulse transmission has been shown below 100MHz frequency range [2]. However, limited work has been done in higher frequency ranges, i.e. up to gigahertz range. Therefore, this paper presents the study of indoor powerline channel characteristics in frequencies up to 1 GHz.
