Fig. 6From: RIS-enabled smart wireless environments: deployment scenarios, network architecture, bandwidth and area of influenceAn example integration scheme of two RISs in a 3GPP network, including a general interface among the different radio access network (RAN) entities. Each RIS panel is assumed to be managed by a dedicated controller that includes a transmitter (TX) and a receiver (RX) modules for exchanging Layer 1 (L1) and Layer 2 (L2) in-band signallingBack to article page
