Indoor Measurements of Reconfigurable Intelligent Surfaces in 5G Millimeter-Wave Networks

This study presents experimental results of reconfigurable intelligent surface (RIS), one the promising technologies for sixth generation (6G) networks, in Turkcell 5G millimeterwave test environment. In this study, an RIS with 1600 reflecting elements has been utilized to establish non-line of sight links between a millimeter-wave (mmWave) base station (BS) transmitting 5G new radio (NR) waveform and a customer premises equipment (CPE). The effect of RIS on received performance metrics of the CPE is demonstrated.
