Abstract：The reconfigurable intelligent surface(RIS) breaks the limitation that traditional wireless communication can only passively adapt to channels, and significantly optimizes the performance of wireless communication systems. In this paper, the main scenarios and guidelines for RIS deployment in wireless networks are discussed. Furthermore, the procedure of an automatic deployment solution for RIS installation is proposed, including determination of signal source location, selection of RIS-deployable areas, selection of optimal deployment location and orientation, generation of optimal codebook sets, and dynamic coordination. Through mathematical modeling, a detailed introduction is given to the determination method of the RIS position and orientation in the automatic deployment problem, and a digital twin simulation system is built. The simulation results show that the proposed solution can effectively provide recommendations for RIS deployment methods and performance quantification.
