  • What is 5G RAN architecture?

    5G is about connecting things everywhere while enabling new use cases. A 5G Radio Access Network (RAN) relies on a fully coordinated, multi-layer network with low-band, mid-band and high-band to provide wireless connectivity to devices and deliver the best network performance.

  • What are the components of 5G RAN architecture?

    5G RAN Architecture
    The gNB incorporates three main functional modules: the Centralized Unit (CU), the Distrib- uted Unit (DU), and the Radio Unit (RU), which can be deployed in multiple combinations. The primary new interface is the F1 interface between DU and CU This are expected to be interoperable across vendors.

  • What is RAN architecture?

    Today, RAN architecture divides the user plane and the control plane into separate elements. The RAN controller can exchange one set of user data messages through a software-defined networking switch and a second set through a control-based interface.
  • When the 5G-AN is a 3GPP NG-RAN, these protocols/layers are defined in TS 38.401. The radio protocol between the UE and the 5G-AN node (eNodeB or gNodeB) is specified in TS 36.300 and TS 38.300. L2 is also called the "Data Link Layer" and the L1 is the "Physical Layer".
