With the popularity of navigation applications and the integration of GPS in user devices, location-awareness is becoming an essential feature demanded by users. Nevertheless, location-awareness in indoor environments is still limited by the inability of GPS to operate indoors. With a centimeter-level ranging resolution, Ultra-Wideband (UWB) is one of the most promising technologies to provide indoor...
Ultra wide-band radio technology is a good candidate for the development of indoor location & tracking networks. Some interesting application scenarios include relatively large and crowded areas such as shopping malls, but the application of short range UWB in these scenarios has to face different challenges, resulting in a trade-off between the positioning error and the amount of resources needed...
Impulse radio (IR) ultra wide-band (UWB) is one of the most promising wireless technologies to develop both indoor and outdoor location and tracking applications. Due to its high bandwidth and short duration pulses, UWB potentially allows a great accuracy in distance measurements based on time of arrival (TOA) estimations. The main objective of this paper is to compare and to provide a qualitative...
