Crowdsensing route reconstruction using portable bluetooth beacon-based two-way network

There have been plenty of R&D efforts to achieve precise indoor positioning of users. With weak or no GPS signals, Wifi / Bluetooth and other approaches such as ultrasonic and accelerometers has been used for indoor positioning. In this demo we focus on reconstructing visitors route using the combination of Bluetooth proximity tags and custom made Bluetooth Beacons. Bluetooth Beacons are usually used to emitting simple identification information for retrieval by a mobile app, which will in turn use this information to get own position from a mobile network. Our custom Bluetooth beacons has the capability to form a two-way network between Bluetooth Beacons, making it highly portable and very easy for deployment. We'll show how to setup the system and how to identify and reconstruct route information of visitors. The information can be used to improve user experience.
