Abstract
A system in one embodiment includes a plurality of Radio Frequency Identification (RFID) readers, each reader being capable of using a single antenna for both transmit and receive functions, wherein, during operation, one of the readers transmits and at least another of the readers receives a response to the transmission from an RFID device. A system in another embodiment includes a plurality of Radio Frequency Identification (RFID) readers, each reader having at least one antenna mounted on a housing thereof, wherein, during operation, the reader transmitting emits a signal sufficient to communicate with a battery assisted passive RFID device at a range of at least 20 meters. Additional systems and methods are also presented.
