Abstract(in English) | For the 6G era of networks, expected to come by the 2030s, high-frequency bands is considered as a medium capable of increasing speed and capacity in communication. However, radio waves in high-frequency bands are particularly vulnerable to shielding and suffer from high distance attenuation. In this context, the use of IRS (Intelligent Reflecting Surface), a device that consists of a planar array of reflective elements that can electrically control the reflective characteristics of its own surface, is considered. IRS enables the creation of new propagation paths that avoid shielding through reflection. Additionally, the signal strength can be amplified by controlling the reflection so that the phase of the directed wave and the reflected wave are aligned. By its nature, the effectiveness of IRS depends largely on its placement. There is a lot of research on the placement of IRS, but most of them rely on simplistic model to find the optimal placement using mathematical modeling. The issue is that the locations where IRS can be deployed in real life scenarios are heavily limited, making it difficult to adapt the optimal placement derived from simplified models to real environments. Thus, this study evaluates the changes in the communication environment caused by the presence and absence of IRS as well as by changes in the location of IRS to determine the optimum placement of IRS in a realistic scenario. Specifically, the effective of IRS and the importance of its placement were clarified through ray tracing in a Wireless InSite simulator. |
