UWB: Innovative architectures enable disruptive low power wireless applications

This work presents the potential offered by new UWB pulse radio transceiver designs. It shows that a judicious architecture selection can be used to exploit the benefit of impulse radio and to reach state of the art performances both in energy efficiency and ranging accuracy The first presented architecture is dedicated to localization application whereas the second one is focusing on high speed and remote powered radio link for the application of ambient intelligent. After a brief description of the application area, the selected architecture are described and justified. Then, the chipset design is presented and the measurements results are summarized. Lastly, perspectives are drawn from the combination of those two developments.
