ISO/IEC 23200-1:2021

Overview

ISO/IEC 23200-1:2021 specifies a laboratory test method to evaluate interference rejection performance between UHF RFID tags (as defined in ISO/IEC 18000-63) and heterogeneous wireless systems (e.g., LoRaWAN, NB‑IoT, WiFi‑HaLow, cellular). The standard defines general requirements, environmental conditions, test set-ups and reporting conventions so stakeholders can compare relative tag performance in a single interference environment or run benchmarking tests for specific applications.

Key topics and requirements

• Scope: Measures how other wireless access technologies affect tag receive sensitivity and overall operation in shared frequency bands.
• Test environment: Controlled air environment at 23 °C ± 3 °C and 40–60% relative humidity; known RF environment recommended (anechoic chamber for propagative tags).
• Test configurations: Supports both bistatic and monostatic interrogator set-ups using test equipment (TE) such as an interrogator emulator compliant with ISO/IEC 18000‑63.
• Far‑field placement: Device under test (DUT) must be in the far field; the standard uses the far‑field distance formula (D = 2L²/λ) and recommends D ≈ 50 cm as a practical minimum in some set-ups.
• Antenna and polarization: Linear (vertical/horizontal) or circular polarization permitted; sufficient isolation required between interrogator transmit/receive ports or via circulator/directional coupler.
• Pre‑conditioning and tolerances: Interrogators should be conditioned for 24 h before testing; default tolerance on equipment and procedure values is ±5%.
• Reporting and uncertainty: Test reports must state total measurement uncertainty and identify DUTs; optional statistical summaries (min, max, mean, standard deviation) are supported.
• Test variations: Procedures cover tag sensitivity under non‑interference and interference environments and allow for different communication parameters (forward/return link).

Applications and users

ISO/IEC 23200-1:2021 is practical for:

• RFID tag manufacturers validating interference robustness
• Compliance and test laboratories performing standardized measurements and benchmarking
• System integrators and solution providers assessing deployments where LPWAN, cellular and RFID coexist
• Network operators and regulators evaluating coexistence and interference mitigation strategies

Use cases include retail inventory, logistics, asset tracking and IoT deployments where UHF RFID must operate reliably alongside LoRaWAN, NB‑IoT, LTE‑M and other wireless systems.
