Evaluation of the interference of pulsed UWB signals over current services in CATV installations

This paper presents an application of ultra- wide band (UWB) technology, consisting on the injection of pulsed UWB signals on community antenna television (CATV) installations. This approach offers the cable installers the possibility for a wide range of new data and multimedia channels on existing CATV installations, with a minimum cost and without altering the transmission of the traditional radio and television channels. The goal of this study has been to estimate the signal levels for which no harmful interference exists for the currently deployed services. Simulations and practical experiments were undertaken, and are presented and discussed in this paper.
