Enhancing Wireless Communications at 300 GHz using RIS in an Industrial Scenario

This paper investigates the use of Reconfigurable Intelligent Surfaces (RIS) to enhance wireless communication in industrial environments operating at 300 GHz. The study focuses on a realistic factory scenario where pillars obstruct direct line-of-sight (LOS) communication. By strategically positioning RIS, signal coverage was improved in an area with shading effects. Ray-tracing simulations were conducted using the Simulator for Mobile Networks (SiMoNe) to evaluate the gain of the received power, especially in areas where the direct coverage of the transmitter (TX) was obstructed by obstacles. Results demonstrate that RIS significantly improves signal quality and coverage, offering a practical solution for overcoming communication barriers in complex industrial environments. The findings highlight the potential of RIS to enhance connectivity in future industrial wireless networks.
