Japan's Pioneering Wireless Power Transmission License

In a groundbreaking achievement for the tech industry, Electric Kogyo Co., Ltd. has become the first company in Japan to acquire a license for a wireless power transmission (WPT) system operating at a frequency of 5.7GHz. This license was granted by the Kanto Bureau of Telecommunications, a division of Japan's Ministry of Internal Affairs and Communications, allowing the company to operate its new technology at its Kanuma plant in Tochigi Prefecture.

The purpose of this cutting-edge WPT system is to enable wireless power transmission to devices situated at a distance, which could revolutionize how factories and warehouses supply power to various equipment such as sensors, displays, and an array of IoT devices. The evolving framework from the Ministry of Internal Affairs has paved the way for the utilization of spatial transmission-based WPT in the 920MHz, 2.4GHz, and now the 5.7GHz frequency bands, with active deployment already beginning in the 920MHz range.

The newly licensed station at the Kanuma facility will implement high-directional beamforming technology, accurately directing power to predetermined receiver locations identified through camera-based estimation. Furthermore, a dual safety mechanism is built into the system, which combines human detection via camera and infrared sensors. This ensure that if any individuals are detected in the vicinity, power transmission will automatically cease, thus enhancing safety measures.

The acquisition of this license marks a significant milestone for Electric Kogyo Co., Ltd., enabling the practical operation of the 5.7GHz spatial transmission WPT system. Moving forward, the company aims to balance the practicality and safety of the WPT technology, facilitating its verification and application for real-world scenarios. With the deployment of such innovations, Electric Kogyo anticipates contributing to industry efficiency and the development of new energy supply infrastructures, focused on reducing manpower and enhancing operational procedures. This aligns with the broader goals of sustainable industrial practices and advancing the technology landscape in Japan and beyond.
