Radio Frequency Testing

1. Core Requirements of TELEC Certification

TELEC certification (also known as MIC certification) is a mandatory wireless equipment compliance approval required by Japan’s Radio Law. It is conducted by certification bodies registered and authorized by the Ministry of Internal Affairs and Communications (MIC). This certification applies to all wireless products sold in the Japanese market, including Wi-Fi, Bluetooth, ZigBee, and 4G/5G modules. The process involves RF testing, technical documentation review, and factory inspection to ensure compliance with the Radio Equipment Regulations regarding frequency bands, power output, and electromagnetic compatibility (EMC). Products without certification are prohibited from sale or use in Japan.

2. Key Criteria for Selecting a Certification Provider

When choosing a TELEC certification service provider, companies should prioritize:

    Official Accreditation: The provider must have direct partnerships with MIC-registered agencies (e.g., JQA, Telec).

    Localized Testing Capabilities: Access to Japan-specific test equipment (e.g., Wi-Fi Channel 14, 920MHz band) and expertise.

    Regulatory Foresight: Up-to-date knowledge of revisions to Japan’s Radio Law (e.g., 2023 updates for 6GHz band rules).

    Multi-Certification Integration: Ability to synchronize with other certifications (e.g., FCC ID, CE-RED, SRRC) to avoid redundant testing.

3. GTG Testing Group’s Service Advantages

GTG offers tailored support for TELEC certification:

    Technical Expertise:

        In-house labs equipped with Japan-specific test systems (e.g., 3/4/5G FR1 band simulators) to meet standards like JATE Annex 43/44.

        Ph.D.-led teams preemptively address issues (e.g., frequency drift, spurious emissions) to reduce compliance risks.

    Efficiency:

        Pre-scan testing + documentation services cut certification time by 40%.

        Direct collaboration with JQA/Telec for expedited reviews.

    Global Coordination: Supports parallel applications for TELEC, FCC, CE-RED, and SRRC to accelerate worldwide market entry.

4. Certification Process Breakdown

TELEC certification involves three phases:

    Pre-Testing Evaluation: RF parameters, SAR values, and EMC tests (per standards like ARIB STD-T66/T109) to optimize product design.

    Documentation Submission: Japanese-language circuit diagrams, PCB layouts, antenna reports, and user manuals.

    Factory Inspection (First-Time Applicants): MIC-authorized audits of quality management and mass-production consistency. Note: From 2024, Japan enforces stricter cybersecurity requirements for IoT devices, including submission of FENICS reports where applicable.

5. Value of Professional Collaboration

TELEC certification poses challenges due to language barriers, unique frequency bands, and complex regulations. Partnering with experts helps:

    Avoid Compliance Pitfalls: E.g., Wi-Fi Channel 14 is restricted to indoor use in Japan.

    Reduce Time Costs: Pre-testing minimizes failure risks, preventing 3–6 month delays from re-submission.

    Adapt to Regulatory Changes: Real-time updates on MIC amendments (e.g., 2023 SAR exemption revisions) ensure ongoing validity.

Notes:

    Technical Terms: Retained acronyms (e.g., EMC, SAR) for industry clarity.

    Localized Details: Added explanations for Japan-specific terms (e.g., "JATE Annex 43/44").

    Grammar/Clarity: Adjusted passive voice (e.g., "Products without certification are prohibited") for readability.
