Ultra-wideband technology: Yesterday, today, and tomorrow

Abstract

In recent years, ultra-wideband communications have attracted increasing interests, since the FCC certification of the UWB spectral mask. UWB research and development have made unprecedented progress in a wide range of applications, including WPAN for high- data-rate multimedia networking, wireless connection and localization among low-power distributed sensors, and body area networking (BAN) for medical as well as entertainment purposes. This paper will provide an overview of UWB technology fundamentals, recent developments, together with envisioned applications and open problems.
