Radio Frequency Testing

Today, with highly developed wireless communication technology, whether it is smart home, industrial interconnection or cross-border e-commerce products, the compliance of radio transmitting equipment has become the core threshold for products to enter the Chinese market. SRRC certification (State Radio Monitoring Center Testing Center), that is, the radio model approval certification of the People's Republic of China, is a legal obligation that every device with wireless transmission function must fulfill before being sold domestically.

1. What is SRRC certification and its legal basis?

SRRC certification refers to the system in which the State Radio Administration (SRRC) approves the spectrum parameters of radio transmitting equipment before it is put into use.

Legal basis and compulsory

According to the Regulations of the People's Republic of China on Radio Administration, all radio transmitting equipment (such as Bluetooth, Wi-Fi, cellular network, radar and other equipment) sold or imported into the PRC must obtain a radio transmitting equipment type approval certificate. Approved products will receive a unique CMIIT ID (Approval Code) and must be marked on the product nameplate.

2. Which products require SRRC model approval?

According to the Guidelines for Model Approval and Issuance of Radio Transmitting Equipment issued by the Ministry of Industry and Information Technology, the scope of supervision covers the vast majority of electronic products that can actively transmit wireless signals:

Public mobile communication equipment: 2G/3G/4G/5G mobile phones, repeaters, etc.

Wireless LAN/Bluetooth devices: smart terminals, routers, and wireless headphones with Wi-Fi 6, Bluetooth 5.0 and above standards.

Micro-power short-distance equipment: remote control, RFID card reader, wireless charging equipment (including communication function).

Special radio communication equipment: digital radio station and microwave communication equipment.

Other radio transmitting equipment: radar, navigation equipment, satellite mobile terminals, etc.

Technical testing core indicators

During the SRRC certification process, the testing agency will conduct rigorous tests on key radio frequency parameters such as frequency range, transmission power, occupied bandwidth, spurious emission, and frequency tolerance of the equipment to ensure that it will not cause harmful interference to other legal radio services.

3. SRRC certification processing process and cost analysis

For manufacturers and cross-border e-commerce, understanding how to apply for SRRC certification and how much SRRC certification costs is the key to project scheduling.

1. Process diagram

Application stage: Submit an application on the China Radio Approval Management Platform and upload business license, technical specification, circuit diagram and other information.

Send samples for testing: After the application is approved, send samples to qualified testing laboratories.

Technical review: The laboratory issues the test report, and the State Radio Administration conducts the final review.

Approval and certification: After the review is passed, the Radio Transmitting Equipment Model Approval Certificate will be issued.

2. SRRC certification fee structure

How much does SRRC certification cost usually consists of two parts:

Test fee: Depends on the wireless technical specifications of the product (such as single Wi-Fi, dual-mode Bluetooth or multi-band 4G/5G). The more frequency bands, the greater the test workload and the corresponding increase in cost.

Service fee: including pre-examination of technical data, sample debugging guidance and follow-up of the whole process progress.

Note: According to the national policy, some qualified enterprises can apply for free testing in the form of government-purchased services, depending on the annual policy and application quota.
