NG-RAN and 5G NR: Understanding 5G Radio Access Network and Radio Interface
NG-RAN, which stands for Next-Generation Radio Access Network, plays a pivotal role in the evolution of communication networks. 5G NR, or 5G New Radio, is the radio access technology that defines the air interface of the 5G network. Understanding the dynamics of NG-RAN and 5G NR is crucial for comprehending the intricacies of the 5G ecosystem. NG-RAN encompasses various components, including gNBs (gNodeBs), which serve as the base stations in the 5G network. The 5G NR radio interface is designed to provide higher data rates, lower latency, and increased capacity compared to its predecessors. It employs advanced technologies such as massive MIMO (Multiple-Input Multiple-Output) and beamforming to enhance performance. This article delves into the technical aspects of NG-RAN and 5G NR, shedding light on the architecture, protocols, and key features that define these critical elements of the 5G network.
