Japan MIC Wireless Certification Testing

Japan MIC wireless certification testing refers to the technical standard conformity testing and certification process implemented by Recognized Certification Bodies (RCBs, such as TELEC) under the supervision of the Ministry of Internal Affairs and Communications (MIC) in accordance with the Radio Law, for wireless transmission equipment entering the Japanese market. In the industry, it is often referred to as "telec certification," "giteki certification," or "Mic certification." As long as a product possesses wireless functions such as Wi-Fi, Bluetooth, Zigbee, 2.4G/5G/6G, 4G/5G cellular, UWB, or RFID transmission, it must, in principle, undergo MIC wireless testing and be affixed with the Giteki mark prior to sale. Otherwise, it may face customs clearance issues, be taken down by e-commerce platforms, or incur regulatory penalties.

What is the Relationship Between MIC and TELEC?

1.MIC (Ministry of Internal Affairs and Communications): Japan's wireless regulatory authority, responsible for formulating technical standards and notifications.

2.TELEC (Telecom Engineering Center): One of the RCBs authorized by MIC; due to its large volume of certification issuance, the industry often collectively refers to "Japan wireless certification" as TELEC certification.

3.Giteki / GITEKI: Refers to the compliance mark (技適マーク) and identification number used on a product after it passes the technical standard conformity proof. It is a certification mark, not the name of an institution.

4.Other RCBs: Besides TELEC, applications can also be accepted by other MIC-recognized bodies such as JQA, UL Japan, and TTC, depending on the laboratory's qualifications and the product's frequency bands.

5.Summary: MIC manages the rules, RCBs like TELEC conduct testing and issue certificates, and the Giteki mark is affixed to the products.

Which Products Must Undergo Japan MIC Wireless Certification Testing?

Judged by "whether there is active transmission," common mandatory product categories include:

1.Bluetooth / BLE: Earphones, speakers, keyboards, mice, smart bands, gateways, medical accessories.

2.Wi-Fi 2.4G/5G/6G: Routers, cameras, smart home devices, laptops, mobile phones, IoT modules.

3.Zigbee / Thread / 2.4G Private Protocols: Smart lights, sensors, gateways.

4.920MHz / 433MHz / 315MHz Short-Range: Remote controls, meter readers, SRD devices (evaluated according to specific low-power rules).

5.Cellular 2G/3G/4G/5G: Mobile phones, modules, automotive T-Boxes, mobile hotspots.

6.Other Active Transmission Devices: UWB, RFID, wireless microphones, walkie-talkies, etc.

Typical Situations for Exemption or Self-Declaration:

1.Pure Reception without Transmission: Devices that only feature GPS reception, radio reception, or passive RFID reading (without transmitting back) generally do not require TELEC certification. However, if they have transmission capabilities to send data back, certification is still required.

2.Weak Wireless / Devices within the Specific Low-Power Directory: These follow sdoc (Supplier's Declaration of Conformity) or exemptions according to the MIC directory; a one-size-fits-all approach is not applied merely because the word "wireless" is present.

3.Telecommunication Terminals Accessing the Public Telephone Network: In addition to TELEC under the Radio Law, JATE (Telecommunications Business Law) certification may also be required.

Testing Standards

The main framework for Japan's wireless RF is MIC Notice No. 88. Appendices are categorized by frequency bands/standards, and type approval is conducted in conjunction with ARIB standards:

2.4GHz Wi-Fi / Bluetooth / Zigbee: Annex 43; reference ARIB STD-T66.

1.The frequency band is usually 2400–2483.5MHz (normally Ch1–13); if the hardware enables Ch14 (2471–2497MHz), Annex 44 is added.

2.The common upper limit for 2.4G EIRP is approximately 100mW (20dBm). Bluetooth frequency-hopping systems are evaluated at 10mW/MHz or product classification limits, subject specifically to Annex/ARIB parameters.

3.Bluetooth requirements include frequency tolerance, number of hopping channels, occupied bandwidth, GFSK/modulation quality, and spurious emissions.

5GHz Wi-Fi (W52/W53/W56, etc.): Annex 45; reference ARIB STD-T71.

1.Frequency allocations follow Japanese rules: W52 (5180–5320), W53 (5250–5350), W56 (5470–5725), etc.; requirements differ for indoor/outdoor use, DFS, and TPC.

2.DFS radar avoidance, channel switching time, and unavailable periods are evaluated; W56 usually has stricter requirements.

3.TPC (Transmit Power Control) is evaluated according to the frequency band.

6GHz Wi-Fi 6E/7: Japan has gradually opened this band and included it in testing. LPI/VLP, AFC (if applicable), power, and bandwidth are evaluated according to current MIC notices/6G rules. Note: Confirm the opened bands and versions with the RCB before drafting a plan; do not directly apply European or American 6G parameters.

Cellular 4G/5G: Governed by independent appendices and ARIB STD-T133/T134, etc.; hand-held terminals require sar testing, and network access requires additional operator/JATE compliance.

SRD / 920MHz: Falls under Annex 49 for specific low-power devices; 920MHz is subject to duty cycle, channel, power, and out-of-band limitations.

EMC / Safety Supplements: Aside from wireless RF, devices with a power supply can undergo J62368-1/PSE testing, and EMC can be supplemented following the VCCI/CISPR 32 approach. However, TELEC itself is not equivalent to PSE or VCCI.

MIC Wireless Certification Testing Items

General RF Mandatory Tests

1.Frequency Error / Frequency Tolerance: The offset of the actual carrier relative to the nominal value (Bluetooth is often at the ±50ppm level, depending on the standard).

2.Transmit Power / Conducted Power / EIRP / ERP: Verifying whether the maximum power exceeds the limit after calculating the antenna gain.

3.Occupied Bandwidth / 99% Power Bandwidth / 3dB Lobe Bandwidth: OFDM is evaluated by channel bandwidth, while frequency hopping is evaluated by single-channel occupation.

4.Modulation Characteristics / Duty Cycle / Transmission Time: Evaluated separately for BLE, DSSS, and OFDM.

5.Transmitter Spurious Emissions: Out-of-band emissions, harmonics, and local oscillator leakage. Scanning typically goes up to several GHz to 12.75GHz, complying with appendix limits.

6.Receiver Spurious Emissions: Unnecessary radiation while in standby/receive states.

7.Antenna Parameters: Type, gain, radiation pattern, and feeder loss; specifications must also be provided for built-in chip/ceramic antennas.

Special Additional Tests

1.5G DFS: Radar waveform detection, channel availability checks, switching, fallback, and silent periods.

2.TPC: Power control declaration and verification for certain 5G frequency bands.

3.SAR / MPE: Near-body devices (phones, earphones, watches, etc.) require sar testing (Japan often references the 1.6W/kg/1g threshold according to applicable standards); far-body devices (like routers) can evaluate MPE.

4.Frequency Hopping Compliance: Bluetooth/BLE channel count, hopping sequence, and dwell time.

5.Channel 14: If a 2.4G product operates on Ch14, Annex 44 applies separately.

6.Cellular Conformance + SAR: 4G/5G tests are extended according to ARIB and network operator requirements.

7.920MHz Duty Cycle / Anti-Interference: LPWA, meter readers, and sensors follow SRD rules.

Japan TELEC/mic certification Process

1.Product Frequency Categorization: List all wireless standards, frequency bands, channels, power ratings, antennas, and software-lockable frequency modes; determine whether the product requires Type Certification, Test Certification, or SDoC.

2.Select RCB and Japanese Responsible Party: Overseas manufacturers usually entrust Japanese agents/importers for submission; prepare a POA (Power of Attorney) and application forms.

3.Translate Technical Documents (English/Japanese): Prepare schematics, block diagrams, PCB layouts, BOM/CDF, antenna specifications, data sheets, Japanese or English manuals, and label diagrams.

4.Sample Pre-Testing (Optional): Pre-scan spurious emissions, power, and occupied bandwidth first. Adjust filters/antennas/firmware before formal testing to reduce re-testing costs.

5.Formal RF/DFS/SAR Testing: MIC-recognized laboratories issue reports; multiple frequency bands are tested separately under Annex 43/44/45 and cellular/ARIB standards.

6.RCB Review and Issuance: The RCB issues the technical standard conformity certificate (Giteki certificate) and assigns a unique identification number.

7.Affix Giteki Mark for Shipping: Permanently mark the product body or packaging with the Giteki mark (技適マーク) + number + manufacturer/importer information; for very small devices, this can be placed in the manual/packaging per MIC rules.

Note: Type Certification is suitable for batch production with identical hardware; Test Certification is for unit-by-unit/small-batch customization. Most mass-market consumer electronics go through Type Certification.

Document and Sample Requirements

Document Checklist

1.Application form, manufacturer/importer information, POA (for non-Japanese enterprises).

2.Product Specifications: Frequency bands, channels, modulation, power, antenna gain, software versions.

3.Circuit schematics, RF schematics, block diagrams, PCB layouts, BOM / Critical Component CDF.

4.Antenna Specifications: Gain, radiation pattern, impedance, and photos (external/internal).

5.Fixed frequency / continuous transmission operation instructions, including steps to enter test mode.

6.Japanese or English user manual, safety warnings, and a Giteki label location diagram.

7.ISO9001 certification or a quality control declaration; existing module telec certificates can be attached for complete machine referencing.

Sample Requirements

1.Standard Samples: 2–3 mass-produced whole units + 1 fixed frequency/conducted sample; complex multi-band devices may require 3–5 units.

2.Fixed Frequency Samples: Must be able to lock channels, lock power, and transmit continuously. For 5G, devices must be able to trigger/output DFS event logs. SAR test samples must use the final mass-produced casings and batteries.

Cycle and Cost Reference

1.Simple Single-Mode Bluetooth/BLE: If documents are complete and the product passes on the first try, commercial testing organizations typically quote a few working days to 2 weeks for testing, with an overall cycle starting at 1–3 weeks. The market base price can be as low as around $1,300 USD, though agency/translation fees are billed separately.

2.2.4G Single-Band Wi-Fi: RF testing takes about 1–3 weeks, with an overall cycle of 4–8 weeks depending on the schedule; the reference cost for single 2.4G testing falls in the 1,500–2,300 USD range.

3.2.4G+5G Dual-Band / Tri-Band (including DFS): DFS increases the required number of samples and the cycle time; dual-band test fees generally range from $2,000 to $5,000 USD.

4.Multi-Mode Bluetooth + Wi-Fi + Zigbee / NFC / UWB: Costs accumulate based on the standards added. Commercial quotes range from $2,200 to $3,500 USD, and are higher for complex systems or multi-SKU product lines.

5.Mobile Phones / 4G / 5G / SAR / Multi-Band: Costs can exceed $10,000 USD, with a cycle of 6–10 weeks or longer; adding JATE, PSE, or vcci certifications will incur separate calculations.

6.Expediting: The process can be compressed if documents and samples are fully prepared upfront, but expedited service cannot be guaranteed in the event of DFS re-testing, SAR re-testing, or label rejections.
