ISO/IEC 18000-62:2012

Overview

ISO/IEC 18000-62:2012 specifies the air-interface parameters and protocol for RFID systems (Type B) operating in the 860 MHz–960 MHz ISM band for item management. It defines the physical signalling and logical command/response behaviour for passive backscatter, Interrogator‑Talks‑First (ITF) systems - describing how readers (Interrogators) energize tags and how tags backscatter data. The standard aims to enable interoperability, compatibility and predictable performance across international RFID products and applications.

Key topics and technical requirements

• Frequency & RF parameters: operating frequency range (860–960 MHz), channel accuracy, occupied bandwidth, maximum EIRP, and spurious emission limits.
• Modulation & coding: Manchester coding on the forward link; physical return link signalling (e.g., FM0 described in the standard).
• Data framing and link parameters: bit rates, bit-rate accuracy, bit transmission order, packet/command formats, CRC/error detection.
• Collision arbitration: an adaptive binary-tree (B-tree) collision arbitration protocol for reliably identifying tags in multi‑tag environments.
• System model: passive backscatter tags (with or without batteries), ITF half‑duplex operation, Interrogator and tag command/response procedures.
• Conformance & testing: methods and obligations for claiming conformance; devices must meet mandatory commands and local radio regulations. Relevant test guidance referenced in ISO/IEC TR 18047-6.
• Optional considerations: frequency hopping, hop sequences, spreading/chip rates, duty cycle, and memory/command optionalities as defined in the document.

Practical applications

ISO/IEC 18000-62:2012 is targeted at item management use cases that require reliable identification and read/write interactions in the UHF band, such as:

• Supply chain & logistics (case/pallet tracking)
• Retail inventory and point‑of‑sale tagging
• Asset management and equipment tracking
• Pharmaceutical and healthcare inventory control
• Library and document tracking

Benefits include multi‑vendor interoperability, robust collision handling in dense tag populations, and consistent RF behaviour for deployment planning.

Who uses this standard

• RFID reader (Interrogator) and tag manufacturers for product design and compliance
• System integrators and solution providers implementing UHF RFID deployments
• Test laboratories and certification bodies performing conformance testing (see ISO/IEC TR 18047-6)
• Standards committees and procurement specifications seeking interoperable item‑management solutions Note: the standard highlights that patent rights may apply and licensing could be required.

Related standards

• ISO/IEC 18000 series (Parts 1, 6, 61, 63, 64 relate to reference architecture and other UHF Types A/C/D)
