About this page
This page presents a partial report from the Information and Communications Council regarding technical standards for wireless power transmission (WPT) systems in the 920MHz band, released by Japan's Ministry of Internal Affairs and Communications on October 20, 2025. WPT systems enable wireless power transfer over 5-10 meters using radio waves, designed for powering sensors in factories and warehouses. As deployment expands in the 920MHz band for low-power applications, improved installation flexibility and broader usage scenarios require technical standard refinements currently under council review.
