Navigating State Radio Regulatory Commission Approvals for Wireless Hardware
Obtaining SRRC type approval requires accredited domestic laboratory testing, valid in-country agency representation, and strict RF emission compliance.
MIIT Notice 2021 No 129
Meaning
Regulatory directives issued by China’s Ministry of Industry and Information Technology establish updated rules for radio transmission equipment in the domestic market. Compliance with MIIT Notice 2021 No 129 is mandatory for all manufacturers wishing to sell wireless devices, including those utilizing Bluetooth and Wi-Fi, within the country. This regulation introduces stricter limits on spurious emissions and updates the technical requirements for modular approvals.
Technical Specification
New parameters defined under this framework focus heavily on preventing mutual interference among the growing number of short-range devices. Under MIIT Notice 2021 No 129, transceivers must implement specific frequency-sharing mechanisms and respect revised out-of-band power limits. Manufacturers must adapt their designs to ensure that test samples can be configured to demonstrate compliance with these exact parameters.
Industry Impact
Equipment suppliers must comply with more rigorous testing protocols to obtain the necessary network access licenses. Adhering to MIIT Notice 2021 No 129 requires closer collaboration between module vendors and host integrators. This shift has prompted many developers to redesign their RF front ends.
Compliance Timeline
Transition periods defined in the regulation dictate when older approvals expire and when new submissions must meet the updated criteria. Since the implementation of MIIT Notice 2021 No 129, all new radio type approval applications must conform to the stricter standard. Devices approved under older rules may face restrictions on imports if their certifications are not updated or renewed.
Importers must proactively audit their product portfolios to identify which legacy certifications require immediate re-testing under the active policy.
