Abstract:
A system and a method for providing location information are provided to enable a user precisely to check a location of an RFID(Radio Frequency IDentification) tag by discriminating whether the location information detected through the RFID tag is agreed with the predetermined rule. Each RFID reader(1201-120N) tries to read the RFID tag(100) attached to a moving object at the same time point by being distributed over a predetermined area, and detects more than one of reception intensity, direction, and time of a reception signal according to reading trial. Each RFID reader generates and transmits the location information by adding the detected information and ID information of the RFID reader to the reception signal. A server(106) includes installation information of the RFID tags, and detects a difference value of more than one of the reception intensity, direction, and time included in each location information by receiving the location information from the RFID readers. The server estimates and guides the actual location information of the RFID tag based on the detected difference value.
