A Low-Cost IoT System for Indoor Positioning Targeting Assistive Environments

The elderly population is increasing, imposing among others a continues demand for customized health-care solutions. Many of these systems rely on accurate indoor positioning in order to activate actuators’ functionalities at assisted environments. Typically these systems rely to Bluetooth and WiFi beacons with accuracy around 1 meter. Throughout this paper, we introduce a low-cost embedded system that rely on Ultra-WideBand technology to enable accurate indoor positioning and navigation. Experimental results with different scenarios highlight the superiority of proposed platform, since the mean error between estimated and actual path can be up to 5-7cm.
