ISO/IEC 15961-4:2016

Overview - ISO/IEC 15961-4:2016 (RFID sensor & battery application commands)

ISO/IEC 15961-4:2016 specifies the application-layer commands and responses used to manage battery-assisted and sensor functionality on RFID tags for item management. The standard defines how an application (or interrogator) communicates with sensor-equipped RFID tags to:

• start and stop battery assistance,
• select or deselect a particular sensor function,
• set and update sensor parameters,
• start and stop sensor monitoring,
• read sensor data, and
• query battery status.

Commands are expressed in an abstract syntax; their concrete encoding and processing are handled via ISO/IEC 24753 and transmitted over RFID air-interface protocols (e.g., ISO/IEC 18000 series).

Key topics and technical requirements

• Application command set: Functional commands for both simple sensors and full-function sensors (clauses cover commands such as Write-Sample-And-Configuration, Read-Alarm-Status, Read-Event-Record-Segments, and others).
• Sensor models: Distinction between memory-mapped or ported simple sensors and full-function sensors with richer configuration and event records.
• Conformance model: Applications must interoperate with a Sensor Processor implementation (ISO/IEC 24753). Implementations support either or both:
  • full-function sensor processing, and/or
  • simple sensor processing.
• Logical interface model: Defines how application commands map to the air-interface layer; commands are independent of specific RFID tag types but rely on ISO/IEC 24753 encoding rules.
• Interoperability & encoding: Object Identifiers and standardized encoding rules ensure sensor configuration and measurements can be read across different systems.

Practical applications and target users

• Manufacturers of RFID tags and sensor modules implementing battery assist and environmental sensing.
• Developers of interrogators/readers, middleware and sensor processors that must decode/encode sensor records and respond to application commands.
• Supply chain, cold-chain logistics, pharmaceutical packaging, food safety, and asset tracking use cases where environmental conditions (temperature, humidity, shock) and battery state must be remotely monitored.
• System integrators and test labs validating conformance and interoperability among RFID sensor products.

ISO/IEC 15961-4 is essential for anyone implementing interoperable RFID sensor solutions that require standardized application commands for battery assist and sensor control. Keywords: ISO/IEC 15961-4, RFID sensors, battery assist, application commands, sensor data, ISO/IEC 24753, item management.
