Japan is undergoing a significant regulatory evolution with the Japan 900 MHz reform Giteki system review, led by the Ministry of Internal Affairs and Communications (MIC). This initiative combines spectrum reallocation with a modernization of the country’s technical conformity certification framework.
The 900 MHz band is a critical low-frequency spectrum widely used for mobile communications due to its excellent coverage and penetration capabilities.
Key Changes
Optimization and reallocation of the 900 MHz band
Gradual refarming of legacy systems
Increased support for LTE, IoT, and future wireless technologies
Exploration of flexible and shared spectrum use models
The Giteki system is Japan’s mandatory certification scheme for radio equipment, ensuring compliance with national technical standards.
Key Review Areas
Simplification and digitalization of certification procedures
Updates to testing standards for emerging technologies
Potential alignment with international certification frameworks
Improved efficiency in approval timelines
