Abstract
A method for locating wireless tags is described. A signal including a RoomID generated by a transceiver is received by a wireless tag. The RoomID identifies a room corresponding to the transceiver and the wireless tag receives the signal asynchronously without being synchronized with the transceiver. A tracking packet including the RoomID and an identifier of the wireless tag is broadcasted by the wireless tag. The tracking packet is received by an access point which provides the tracking packet to a localization system that determines a location of the wireless tag based on the RoomID.
