This article addresses an energy-efficient positioning system using Ultra-Wideband (UWB) technology. Positioning systems play a crucial role in various applications such as disaster rescue, autonomous robots, and industrial automation. However, in such environments, IoT devices rely on batteries, and UWB systems have been limited in energy efficiency compared to other wireless communication technologies. In this study, we propose a high-resolution positioning algorithm for UWB systems with reduced communication frequency to enhance energy efficiency while providing real-time location information. Experimental results demonstrate that reducing the UWB communication frequency leads to increased energy efficiency. We also analyze the relationship between real-time location update speed and the energy constraints of IoT devices. Finally, we compare the performance of UWB systems with the high-resolution algorithm to conventional triangulation methods. This research provides a fundamental basis for improving energy-efficient positioning systems using UWB technology.
