The method can include providing, by a mobile computing device, at least a first ultrasonic signal to a first and a second self-organizing beacon device. The method can include receiving, by the mobile computing device, a first radio frequency signal including the location of the first beacon device and a second radio frequency signal including the location of the second beacon device. The method can further include determining a first time-of-flight associated with the first beacon device and a second time-of-flight associated with the second beacon device. The method can include determining a location of the mobile computing device based at least in part on the first time-of-flight, the second time-of-flight, the location of the first beacon device, and the location of the second beacon device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Self-organizing hybrid indoor location system","description":"Systems and methods for identifying device location are provided.
