Abstract
Systems and methods are provided for monitoring a plurality of RFID tags. A receiver selection signal is sent along a receive path that includes a plurality of serially connected receivers. A receiver relays the receiver selection signal, listens for an RFID response signal, or operates in a standby mode based on the receiver selection signal. A transmitter selection signal is sent along a transmit path that includes a plurality of serially connected transmitters. A transmitter relays the transmitter selection signal, transmits an identification impulses, or operates in a standby mode based on the transmitter selection signal. The identification impulse is transmitted from the selected transmitter and an RFID response signal is received at the selected receiver.
