Denki Kogyo Co., Ltd. (Head Office: Koto-ku, Tokyo; President: Tadatōshi Kondō) has obtained a radio station license from the Kanto Bureau of Telecommunications for a 5.7GHz band spatial transmission wireless power transmission system to be installed at its Kanuma factory in Tochigi Prefecture. This marks the first radio station license in Japan for a 5.7GHz band spatial transmission wireless power transmission system. Spatial transmission wireless power transmission (WPT) systems are technologies that wirelessly transmit power to devices at a distance and are expected to be used as a power supply method for sensors, displays, and various IoT devices in factories and warehouses. With the establishment of regulations by the Ministry of Internal Affairs and Communications, environments for spatial transmission WPT in the 920MHz, 2.4GHz, and 5.7GHz bands are being prepared, with practical use already expanding in the 920MHz band. The radio station licensed this time uses high-directivity beamforming technology to supply power to the position of the receiving side estimated by a camera within the 5.7GHz band. For safety, in addition to camera-based human detection, it is equipped with dual stop functions combining an infrared human sensor, which stops transmission when human entry is detected. With the acquisition of this radio station license, operation of the 5.7GHz band spatial transmission WPT system is now possible within Denki Kogyo's Kanuma factory. Moving forward, the company will promote verification and utilization towards practical operation, aiming to balance the practicality and safety of spatial transmission WPT.
