SRRC Short Range Devices (SRD)

• SRRC type approval is mandatory for all short-range devices (SRDs) in China that exceed micro-power limits or use regulated frequency bands.

• Testing must be conducted in-country at MIIT-designated laboratories.

• SRRC approval is required for common 2.4 GHz, 5 GHz, and 5.8 GHz technologies such as Bluetooth, Wi-Fi, and Zigbee.

• Certified devices must be labeled with a CMIIT ID, and foreign manufacturers must appoint a local filing entity.

• There is no modular approval exemption under SRRC rules.

In China, short-range radio technologies such as Bluetooth, Wi-Fi, and Zigbee are classified as radio transmission equipment and require SRRC type approval if they exceed micro-power limits. These technologies are essential to modern wireless systems across consumer, industrial, and automotive sectors.

This page outlines key certification requirements, frequency conditions, and labeling rules for SRD technologies—organized by radio type.

Bluetooth devices—including Classic (BR/EDR) and Low Energy (LE)—are subject to mandatory SRRC type approval in China if they exceed micro-power limits or operate in regulated bands.

Key compliance requirements include:

• In-country testing at MIIT-designated labs

• Verification of frequency hopping behavior (for Classic Bluetooth)

• Evaluation of RF parameters such as output power, bandwidth, and spurious emissions

• Submission of complete technical documentation in Chinese

• Labeling with a CMIIT ID, affixed to the device or manual

Bluetooth typically operates in the 2.4 GHz ISM band. If the transmit power exceeds 10 mW EIRP, SRRC approval is required. Pre-certified modules are not exempt and must undergo approval individually.

UWB devices must obtain SRRC type approval in China if they transmit in the regulated UWB bands. Approval currently applies to the frequency range 7163–8812 MHz and is subject to specific technical and operational constraints.

Key compliance requirements include:

• Testing at MIIT-accredited laboratories in China

• Verification of emission limits and pulse characteristics

• Use-case restrictions (e.g., indoor-only, non-interference)

• Labeling with a valid CMIIT ID

• Local representative for application and registration

• Validity of SRRC certificates for UWB devices is typically limited to one year

UWB devices must operate within the defined spectrum and comply with MIIT power and bandwidth rules. Pre-certified modules are not exempt from approval.

Note: UWB operation in China is governed by MIIT Announcement No. 77 [2024], which defines the permitted frequency range and conditions for market access. This regulation supersedes the earlier MIIT No. 354 [2008] and enables UWB approval under the SRRC regime. → Read the full MIIT announcement on UWB equipment

→ For a global overview of UWB regulations, see the Ultra-Wideband – Technology and Compliance page.

All SRRC-certified products must carry a valid CMIIT ID. Placement, format, and visibility rules depend on the device type and form factor.
