摘要： A location awareness system using RFID and a wireless communication apparatus for the location awareness are provided. The location awareness system includes a RFID tag, a wireless communication apparatus for location awareness, more than three anchors, a coordinator, and a server. The wireless communication apparatus identifies the target object with the RFID attached through communicating with the RFID tag. The anchors receive information about the identified target object and measuring a distance by communication with the wireless communication apparatus using a predetermined wireless communication scheme. The coordinator collects the measure distance and the information from each of the anchors. The server calculates a location of the target object by receiving information about the measured distances and the target objects from the coordinator and calculating the location of the wireless communication apparatus using the received information.
