IEEE/ISO/IEC 21451-7-2011

This part of ISO/IEC/IEEE 21451 defines communication methods and data formats for transducers (sensors and actuators) communicating with RFID tags. This part of ISO/IEC/IEEE 21451 also defines Transducer Electronic Data Sheet (TEDS) formats based on the ISO/IEC/IEEE 21451 series of standards and protocols for accessing TEDS and transducer data. It adopts necessary interfaces and protocols to facilitate the use of technically differentiated, existing technology solutions. It does not specify transducer design or signal conditioning. There is currently no openly defined independent interface standard between transducers and RFID tags. Each vendor builds its own interface. Without such a standard, transducer interfacing and integration to RFID tags and systems are time-consuming and all vendors' duplicated efforts are economically unproductive. The purpose of this part of ISO/IEC/IEEE 21451 is to provide interfaces and methods for interfacing transducers to RFID tags and reporting transducer data within the RFID infrastructure. It also provides the means for device and equipment interoperability.

As this project is being jointly developed with ISO/IEC JTC 1/SC 31, the document will not contain a purpose clause.

Revision Standard - Inactive-Reserved. ISO/IEC/IEEE 21451-7:2011 defines data formats to facilitate communications between radio frequency identification (RFID) systems and smart RFID tags with integral transducers (sensors and actuators). It defines new Transducer Electronic Data Sheet (TEDS) formats based on the ISO/IEC/IEEE 21451 series of standards. It also defines a command structure and specifies the communication methods with which the command structure is designed to be compatible.
