This document establishes the air interface based on ISO/IEC 18000-63 for radio frequency identification (RFID) devices operating in the 860 MHz to 930 MHz range used in sensing as well as item management applications.

This document specifies the physical and logical requirements for a passive-backscatter Interrogator-Talks-First (ITF) system.

This document specifies:

• logical and physical procedures between the interrogator and tags to allocate a dedicated subcarrier channel to each of the tags to produce continuous data streaming;
• logical and physical procedure between the interrogator and the tags to start and stop the continuous data streaming;
• logical interface between the interrogator and the tag to configure a digital sensor and to receive data from the digital sensor through the tag.
