Rationale: In manufacturing, production, defense, homeland security, and supply chain systems,

RFID tag tells what a product is, but does not tell what condition it has been gone through throughout its life cycle.

Sensor(s) tell the condition of a product by measuring temperature, vibration, presence of chemical and other relevant parameters

Combining tags and sensors could expand the overall functionality and capability of the RFID systems.

Networking RFID can realize the same benefits of wireless sensor mesh networks.

Universal RFID and sensor standards ensure interoperability and are necessary for successful RFID deployments worldwide, for ex: ease the processing of secure cargo containers shipped worldwide.

Challenges/Questions

Can IEEE 1451 be a basis for RFID tag/sensors ? For active tags

In a collaborative business environment, the tags on products communicate and share data with each other. In the network, each RFID sensor node, or tag, can collect data and transmit it to any other node in the network. IEEE 1451’s distributed sensor architecture is such that

each NCAP can communicate with each other. Each tag transmits not only its unique ID number but also

details of its environment and content. IEEE 1451 sensor’s TEDS contains an UUID (unique

identification number) and sensor data tell the environment that it monitors.

Coordination with ITU, ISO, and EPCglobal Coordination with ITU, ISO, and EPCglobal on Sensor-enabled RFIDon Sensor-enabled RFID

Establish liaison with ITU-T and IEEE 1451 on future sensor integrated networked RFID standards development.

Key Points

IEEE 1451 Smart sensor interfaces are open industry sensor

networking standards.

RFID and sensors are key enabling technologies for supply

chain in the not so distance future.

Networking sensors (wired and wireless) is the enabling

technology for remote sensing, internet access, and tracking.

Fixed and mobile sensors are needed to augment RFID in

applications.

Unifying smart and wireless sensor standards and RFID

standards is essential to achieve interoperability.

Interoperability is the key of success for RFID.
