Optimal Receivers Location for Passive Indoor Positioning based on BLE

Conference: IPIN 2021 WiP ProceedingsAt: November 29 – December 2, 2021, Lloret de Mar, SpainIndoor Positioning Systems are attracting many researchers, being Bluetooth Low Energy gaining some attention recently. The recent need to track people, ensuring low density of people in some areas, made the research community to provide unintrusive tracking. In contrast to traditional direct !ngerprinting, where the user utilizes their mobile to estimate its location based on the BLE infrastructure, we propose the other way around. The users wear a beacon which is sensed by the monitors deployed and inverse !ngerprints are generated for a particular object of interest. We propose in this paper a simulation-based approach to retrieve the most interesting monitor distribution, providing a real-world validation. The results show “passive” positioning errors of 3 meters in an o"ce sensed with 5 monitors
