Enabling high accuracy pervasive tracking with ultra low power UWB tags

Abstract

With the recent popularity of active ultra-wideband (UWB) tracking beacons, the next era of low-power IoT aims to offer tracking as a core feature in numerous enterprise and industrial applications. However, generating high-bandwidth tracking signals on cost-effective, low-power tags in a large scale deployment, poses fundamental challenges in energy-cost-performance trade-offs, not afforded by existing solutions that fall short in one or more critical dimensions.
