Southeast University and China Mobile:The reconfigurable intelligent surface (RIS)-aided millimeter wave communications system
Introduction
Introduction
The reconfigurable intelligent surface (RIS)-aided millimeter wave communications system shown in this video is jointly developed by Southeast University and China Mobile. The RIS can direct the reflected beam to dynamically track the movement of the UE. In the demo, both AP and RIS are in fixed locations, while the position of UE is changing. When RIS is switched off, the received signal quality gets worse as UE moves and the average received power is about -80 dBm. When RIS is switched on, the received signal quality can be maintained at a good level as UE moves and the average received power is about -64 dBm.
