What is Japan MIC Certification?

MIC certification is a mandatory certification for wireless products entering the Japanese market. MIC refers to the abbreviation of the Ministry of Internal Affairs and Communications in Japan. It oversees the Radio Act and the Telecommunications Business Act. Previously, certification under the Radio Act was also called TELEC certification, but officially, it is more appropriate to refer to it as Japan Mic certification. In short, telec certification equals mic certification.
