A radio frequency identification (RFID) interrogator housed in a portable platform that includes at least one antenna, a transceiver for transmitting and receiving a radio frequency (RF) signal through the antenna, and a controller in communication with the transceiver for adjusting power and direction of the transmitted RF signal. The controller can be configured to adjust the antenna orientation, and can also selectively activate and deactivate one or more antennas. |
