Abstract
The next-generation wireless networks are poised to undergo major shifts in their underlying technologies. This is unavoidable if they are to support the new and advanced services that are geared towards the provision of the ultimate user experience through hyperconnectivity, which is only achievable through wireless networks characterized by ultra-high reliability and data rates, negligible latencies, and very low error rates. The reconfigurable intelligent surface (RIS) has been earmarked as the novel antenna technology for future wireless networks with applications spanning from wireless communication, localization, and radio sensing. This paper explores the RIS technology by delving deeper into the reasons that make the RIS an attractive prospect for next-generation wireless networks and highlighting some of the considerations that need to be made while integrating RISs into communication networks. Simulation results considering a single-input single-output (SISO) communication system show that significant improvements in spectral efficiency can be achieved when the RIS is incorporated. Increasing the number of RIS elements results in a rise in spectral efficiency. The results further demonstrate that the enhancement impact of RIS is particularly great in cases where the direct path between the transceivers is very weak.
