Performance Investigation for IEEE 802.15.4z-compliant SiP-assisted Ranging

In recent years, ultra-wideband (UWB) has emerged as a preferred choice for precise wireless indoor localization and navigation systems. The inherently better ranging performance and stronger resistance to multipath fading compared to previously used technologies have led to increased research on the performance of UWB devices. However, regulatory requirements on transmission power constrain UWB communication range. This paper studies the impact of different PHY settings of an 802.15.4z-compliant SiP, the Qorvo DWM3000, in a comprehensive set of real-world measurements. Furthermore, we focus on range maximization and high reliability when power consumption or air utilization is not constricted. Results show that with a commercial off-the-shelf UWB SiP, a maximal reliable range of 125 meters with an overall mean accuracy of 25.1 cm can be achieved while staying within the regulatory limits.
