    摘要: An RFID monitoring arrangement comprises a first RFID device and a second RFID device for monitoring the first RFID device. The first RFID device transmits at least two messages each including unique identifying information and a power level code, wherein the transmitter power level corresponds to the power level represented by the power level code in each transmitted message. The second RFID device receives messages transmitted by the first RFID device and processes the identifying information and the power level code to provide an indication of a condition. Messages received from said first RFID device, the indication of a condition, or both the messages received from said first RFID device and the indication of a condition, may be relayed to a remote location.

    摘要: A system for monitoring a container comprises an RFID device interior the container and a receiving device exterior the container. The RFID device transmits messages each including unique identifying information, and the receiving device exterior the container receives and stores and/or relays messages received from the RFID device interior the container. Ones of the messages transmitted by the RFID device when the container is closed are not received by the receiving device and ones of the messages transmitted by the RFID device when the container is not closed are received and stored by the receiving device, whereby the messages stored in the receiving device provide an indication of whether the container has or has not been opened. Messages may include power level codes and be transmitted at more than one power level, and may be processed for locating and/or tracking the container.

    摘要: An RFID system and method utilizes the power level of messages received from an RFID device for monitoring and/or locating and/or tracking the RFID device, e.g., and typically an object associated with the RFID device. The power level of received messages may be indicated by power level information contained in the message, or by the strength of the received signal carrying the message, or by both. The RFID system and method may be employed to monitor a condition of an object, e.g., a closable container, as to whether it is and/or has been closed or not, including being tampered with. Messages received from the RFID device, as well as an indication of a condition, may be relayed to a remote location.
