Radio Frequency Testing

Wi-Fi modules (2.4GHz and 5GHz) used in products destined for the Chinese market are subject to SRRC type approval. This guide walks through the workflow, required files, cost and schedule factors, and the compliance risks across global e-commerce platforms.GTG EMC Lab helps Wi-Fi module suppliers plan SRRC alongside FCC and CE-RED.

What is SRRC for Wi-Fi modules

SRRC (State Radio Regulation of China) is the mandatory type approval for radio equipment in China. Wi-Fi modules operating in the 2.4GHz or 5GHz bands are radio transmitters and must obtain an SRRC certificate before domestic sale or integration.

Applies to　Wi-Fi 2.4G / 5G / dual-band and Wi-Fi plus Bluetooth combo modules

Key basis　MIIT micro-power short-range equipment rules and related SRRC test requirements

Wi-Fi module SRRC certification process

1. 1Capture RF specs: band, channel, transmit power, bandwidth, and antenna data.
2. 2Pre-compliance check: screen frequency tolerance, power, and spurious emission early.
3. 3Laboratory testing: submit samples for formal SRRC RF testing.
4. 4Compile technical dossier: descriptions, diagrams, and test reports.
5. 5Submit for approval: authority reviews and issues the certificate.

Documents you need to prepare

• SRRC application form with technical description
• RF test report, circuit and RF block diagrams
• Antenna specification and gain information
• Representative samples
• Business license and agent authorization (if applicable)

What drives the certification cost

Cost rises with RF complexity: a single 2.4GHz Wi-Fi module costs less to test than a dual-band Wi-Fi plus Bluetooth combo. GTG EMC wireless compliance service Test scope, pre-compliance support, and agency fees also affect the total. Share the module sheet for a tailored quote.

What drives the timeline

Timeline is influenced by product type, number of test items, sample condition, and document quality. Well-prepared samples and complete files shorten the path; re-testing after limit failures extends it. Keep buffer time relative to your go-to-market date.

Cross-border marketplace and export risk

For China, SRRC is required; for export, the United States needs FCC, the EU needs CE-RED, and Korea needs KC. GTG EMC Lab Dual-band and combo modules raise test complexity, so align country limits during component selection.

Q1　Do Wi-Fi modules need SRRC in China?

Yes. Any Wi-Fi module (2.4GHz or 5GHz) sold or integrated into products in China is a radio transmitter and requires SRRC type approval.

Q2　Is SRRC the same as CCC?

No. SRRC covers radio type approval; CCC is a separate compulsory product certification. Some finished products may need both, depending on the catalogue.

Q3　What does a Wi-Fi module need for the US market?

The finished product generally needs FCC certification covering EMC and radio compliance. Module selection affects the ease of passing.

Q4　Can one test report serve multiple countries?

Test data can sometimes be shared across schemes like FCC and ISED, but SRRC, FCC, and CE-RED remain distinct approvals with their own limits.
