Abstract (in Japanese) (See Japanese page) 
(in English) Society5.0 and Industry4.0 advocate the application of wireless Internet of Things (IoT) technology to realize smart factories. In such a factory, a lot of IoT devices communicate with between moving machine tools, Automated Guided Vehicles (AGVs), and moving workpieces despite there is the limit of frequency bands for wireless IoT usage. Therefore, applying for a directional beam is considered as an effective approach to suppress interference between different wireless communication systems and improve space utilization efficiency. In this technology exhibit, we introduce 5 GHz-based simplified beamforming wirelss IoT communication using Wi-Fi backscatter system. This system is assumed that sensor node (SN) is attached to moving/rotating machine tool arm or tips, and access point (AP) is attatched to basement of the machine tool.
