RFID device with wide area connectivity

摘要

Methods and apparatus relating to a radio frequency identification device (RFID) with wide-area connectivity are provided. In an example, a real-time location (RTL) monitoring device is provided. The RTL monitoring device includes a first radio-frequency identification (RFID) tag and an RFID interrogator configured to interrogate the first RFID tag and a second RFID tag. A long-range wireless transceiver is coupled to the RFID interrogator, and configured to communicate RFID data. The first RFID tag, the RFID interrogator, and the long-range wireless transceiver can be collocated in an enclosure separate from the second RFID tag. The RTL monitoring device is configured to aggregate a plurality of responses from the first and second RFID tags, and to communicate the aggregated RFID data with a second device, such as a satellite, a base station, and/or an eNodeB device.

主权项

1. An apparatus comprising:
an internal radio frequency identification (RFID) interrogator configured to interrogate at least one external RFID tag and to aggregate one or more responses from the at least one external RFID tag to form aggregated RFID data; an internal RFID tag configured to send the aggregated RFID data to an external interrogator; a sensor port configured to receive sensor data; and a long-range wireless transceiver coupled to the sensor port and to the internal RFID interrogator and configured to:
send the aggregated RFID data and the sensor data via a network;send an alert to the second device in response to the sensor data satisfying a threshold; andreceive write data, wherein the internal RFID tag is configured to store the write data.
