NG-RAN and 5G NR represent the cutting-edge advancements in radio access network technology, ushering in a new era of connectivity. NG-RAN, or Next-Generation Radio Access Network, serves as the foundation for the deployment of 5G networks, enabling enhanced performance and capabilities. The 5G NR (New Radio) technology, which defines the air interface, introduces significant improvements in data rates, latency, and overall network capacity. Within the NG-RAN framework, gNBs (gNodeBs) play a crucial role as the base stations, facilitating seamless communication in the 5G ecosystem. This article explores the technical nuances of NG-RAN and 5G NR, highlighting the architectural components, protocols, and key features that contribute to the efficiency and effectiveness of the 5G radio access network.
