RIS4NGWB - reconfigurable intelligent surfaces for next generation wireless backhaul

The planned joint project deals with security in the 5G / 6G backbone. Based on existing network components and preliminary work of the partners, reconfigurable intelligent surfaces (RIS) controlled via software-defined networking (SDN) will be deployed and demonstrated in the wireless backhaul to increase security and resilience. The RIS is the physical core component and subject of this subproject. It enables additional paths for the radio links between individual 5G / 6G access points. On the one hand, this can neutralize potential interferers or temporarily increase capacity (resilience), but on the other hand possible eavesdropping can be made more difficult, since the information is transmitted on more than one path (physical layer security). Targeted and controlled multipath generation is the task of RIS and is to be realized in this subproject and demonstrated together with the partners.
