Survey of indoor positioning systems based on ultra-wideband (UWB) technology

Abstract

Indoor positioning is a challenging research area, and various kinds of indoor positioning systems have been developed based on different technologies. Ultra-wideband (UWB) positioning technology is mainly used for high-accuracy indoor wireless positioning. This paper provides an overview of indoor positioning solution based on UWB technology. First, the conception, standardization, and advantages of UWB were introduced, and then four location measure techniques based on UWB technology are analyzed. Finally, the applications and future trends for the technology are provided.
