Patent attributes
A system and a method for determining the location of an RFID reader is provided. The system includes a plurality of transmitters which have a known reference point. Each transmitter includes a circuit for transmitting a sequence of unique RFID pseudo tag signals. Each unique RFID pseudo signal in the sequence has a unique range of transmission. Each unique RFID pseudo tag in the sequence has a tag identification indicating the range of transmission of the pseudo tag signal and a transmitter identification value indicating the transmitter from which the pseudo tag signal was transmitted. An RFID reader receives the unique RFID pseudo tag signals and distinguishes between each received unique RFID pseudo tag signal. A location calculator calculates the location of the RFID reader based on the information received.
