Today, many industrial sites are focusing on the promotion of DX as a solution to labor shortages. In order to promote labor saving and automation, wireless communication is being actively introduced in such situations as on-site sensing, data linkage, and automatic control using robots. However, the difficulty of building and maintaining an uninterruptible wireless communication environment has become apparent in the process of promoting wireless communication in the field. In this presentation, we would like to discuss the possibilities of using digital twin technology to realize uninterruptible wireless communication, its creation value, and future prospects, after summarizing the challenges of wireless communication at various industrial sites that we have learned through our support of wireless communication at various sites.
