Abstract:
A novel solution to generate an optimal spatial placement map of Radio Frequency (RF) beacons, such as Bluetooth Low Energy (BLE) beacons, which can be used for indoor localization. A described embodiment solves for both generating optimal number of beacons required in a given environment and optimizing their location. The solution also incorporates behavior of RF signal due to various environmental factors such as signal reflection and absorption due to static and dynamic obstacles. In one embodiment, the framework is built upon Genetic Algorithm (GA) for optimization of beacon placement. The experimental results achieved using one implementation of the described method reduced the number of beacons by 50% as compared to beacons placed using expert knowledge. Furthermore, the overall localization error increased by ˜0.4 m when the results using the RF/BLE map generated by the described system were compared with the RF/BLE map generated using expert knowledge.

Claim (Index 14):
A computerized system comprising a central processing unit, a localization signal receiver and a memory, the memory storing a set of computer-readable instructions causing the system to perform a method comprising:\n a. using the central processing unit for determining an optimal number of beacons in a plurality of beacons to be placed in an environment to achieve an optimal localization, wherein the optimal number of beacons is determined based on a cost function, which combines a beacon coverage requirement and a beacon spread requirement to determine the optimal number of beacons; and b. using the central processing unit for determining an optimal placement of the beacons from the plurality of beacons in the environment to achieve the optimal localization.
