• Sommario/riassunto: Ultra-wideband (UWB) has been among the most controversial technologies of modern times. Its applications seem endless, its capabilities miraculous and yet it is so poorly understood. In this volume, the authors combine talents to de-mystify ultra-wideband radio and explain it in language that is accessible to non-technologists as well as technologists. They contrast UWB with conventional radio technology so that fundamental, technically accurate information devoid of specific technical and analytical details is accessible for marketing managers, business developers, engineering managers, tech
