Abstract
A positioning server is connected to a collection of access points, base stations, NFC stations, and image or video cameras and the collected data is used for positioning objects. A plurality of electronic devices are paired with an object by tracking the position of the object based on imaging and the position of electronic devices based on RF signals in vicinity of the object. Once a device is paired with an object, the propagation channel profile measured through the electronic device is used to develop and tune a database of channel profiles versus location. This database is used based on signature/profile matching and correlation for positioning devices and objects that do not have pairing or have poor image-based positioning accuracy or reliability. When a device is detected that cannot be paired with any object, or a device that is unpaired from a previously associated object, a theft or loss alert is generated.
