Ultra-Wideband Communications: A New Spectrum Survey and Challenges Ahead

Abstract

The idea of ultra-wideband (UWB) communications for short ranges (up to a few tens of meters) has been around for nearly three decades. However, despite significant efforts by the industry, UWB deployment has not yet reached its predicted potential. This article, thus, seeks to rectify this situation by providing a practical examination of UWB interference conditions. Through a spectrum survey of today's wireless environments, we quantify the level of interference that UWB devices may face and explore the signal processing steps that must be taken to materialize the full potential of UWB communications.
