Observations on Low Data Rate, Short Pulse UWB Systems

Since the FCC's First UWB Report & Order in 2002, much commercial emphasis has been placed on high data rate applications such as wireless USB, video transfer, etc. This paper addresses the other extreme of low data rate UWB systems which have rather unique properties for certain sensor applications. Starting with the FCC constraints on peak and average power densities, the asymptotic bounds on system performance - EIRP, range and interference potential - are investigated for low PRF UWB system designs.
