Ultra-Wideband: The Possibilities Beyond The Legacy Communications: Cross Layers Design

Ultra-Wideband (UWB) is an alternative wireless communications technology that offers high bandwidth wireless communications without the constraints of spectrum allocation. Fundamentally different from conventional radio frequency communications, UWB relies on a series of narrow, precisely timed pulses to transmit digital data. Transmitters and receivers that use UWB can be much simpler to build than their conventional counterparts, resulting in lower cost and higher power efficiency. Moreover, the inherent properties of UWB emissions allow them to potentially coexist with conventional wireless systems on a non-interfering basis. This book envisages the uniqueness features that UWB can provide for indoor and low rate outdoor communication arenas.
