Abstract

As the multi-user wireless communications in Industrial Internet of Things (IIoT) scenarios are increasingly demanded, conventional visible light communication (VLC) solutions suffer from the problems such as the inter-cell crosstalk and the latency when switching the cells. The introduction of reconfigurable intelligent surface (RIS) supplies new approach of reconfigurable optical cells based on digital holography. This paper proposes the prototype model of the holography-based multi-user VLC system. The computer-generated holograms (CGH) generation quality is analyzed, and the lens system to adjust the positions and the sizes of the generated cells is designed. The feasibility of the system is verified by simulation, which shows that the method can support 5 users data transmission.
