Abstract
Systems and methods are provided for monitoring a plurality of RFID tags. A system includes a plurality of serially connected transmitters along a transmit path, where each of the serially connected transmitters are configured to relay a received transmitter selection signal when the transmitter selection signal identifies a selected transmitter as being further along the transmit path than the serially connected transmitter and transmit an identification impulse using a transmit antenna when the transmitter selection signal identifies the serially connected transmitter as being the selected transmitter. A system further includes a control unit responsive to a plurality of transmit paths, the control unit being configured to send the transmitter selection signal along a selected transmit path, where the transmitter selection signal identifies one of the plurality of serially connected transmitters along the selected transmit path as the selected transmitter for transmitting the identification impulse.
