Abstract—To reduce the theft rate of smart phones, laptops and tablets in public, this paper proposes a novel network based anti-theft alert system using a dynamic hybrid time of arrival (TOA)/angle of arrival (AOA) algorithm. Specifically, the statistic weights of the results produced by the TOA and AOA methods are dynamically varied according to the signal propagation environment. In this way the combined result can be as accurate as possible regardless of the environment. The feasibility and advantages of this hybrid TOA/AOA algorithm are verified by numerical simulations. Moreover, the implementation proposal, several practical issues, and the social impacts of the system are elaborated and analysed in details.
