  11. 11. eNB & gNB ©3G4G • eNodeB (eNB) – LTE access network from 3GPP Rel-8 up to 3GPP Rel-15. For an eNB to connect to a 5G network (Standalone or Non-Standalone), it would have to be 3GPP Release-15 or above. • An eNB only supports legacy E-UTRAN interfaces (S1, X2, etc.) and does not support next-generation interfaces (NG, Xn, etc.). • Next generation nodeB (gNB) – 5G access network from 3GPP Rel-15 onwards. • node providing NR user plane and control plane protocol terminations towards the UE, and connected via the NG interface to the 5GC. • gNB does not support legacy E-UTRAN interfaces
