How do I design an RF device to meet the Japanese TELEC certification requirements?
TELEC Certification
TELEC certification (or more broadly, MIC radio equipment certification) is mandatory for any radio transmitter sold or operated in Japan. Japan has one of the most demanding regulatory environments for RF devices, with specific requirements that differ from FCC and CE marking.
- Performance verification: confirm specifications against the application requirements before finalizing the design
- Environmental factors: temperature range, humidity, and vibration affect long-term reliability and parameter drift
- Cost vs. performance: evaluate whether the application demands premium components or standard commercial grades
- Interface compatibility: verify impedance, connector type, and mechanical form factor match the system architecture
Frequently Asked Questions
Can I use FCC test data?
Partially: some test data is transferable, but Japan's technical standards differ from FCC Part 15 in several areas: Japan uses ARIB (Association of Radio Industries and Businesses) standards, which have unique test methods and limits. For 2.4 GHz WLAN: the power density limit (mW/MHz) differs from FCC's peak conducted power limit. For 5 GHz RLAN: Japan requires DFS testing to a Japanese-specific radar pattern set (different from FCC/ETSI). Receiver tests are required (FCC does not test receiver performance). You will typically need additional testing at a MIC-recognized laboratory, even if you have FCC test reports.
What is the Giteki Mark?
The Giteki Mark (技適マーク) is the Japanese certification mark for radio equipment and telecommunications terminal equipment. It consists of a circled R (for radio equipment) or a circled T (for telecommunications equipment). The mark must be: displayed on the device (either on the exterior or on the screen if the device has a display), accompanied by the certification number, and visible without disassembly. Operating a radio transmitter without the Giteki Mark in Japan is illegal (Radio Law Article 4), with penalties including fines and imprisonment.
What about 5G NR certification?
5G NR certification in Japan: MIC has established technical standards for 5G NR in: Sub-6 GHz: n77 (3.3-4.2 GHz), n78 (3.3-3.8 GHz), n79 (4.4-5.0 GHz). mmWave: n257 (26.5-29.5 GHz). The certification process requires: OTA (Over-The-Air) testing for beamforming antenna systems, SAR and power density testing per Japanese-specific methods, and comprehensive receiver performance testing. Many of the 5G NR tests are aligned with 3GPP TS 38.521/522, but Japan may impose additional requirements.
