Types of 5G NR Base Stations: A Comprehensive Overview
Understanding these base stations is crucial for network planners, engineers, and businesses looking to optimize connectivity. This article provides a detailed overview of the
A 5G Base Station is known as a gNode B (next 'generation' Node B). This is in contrast to a 4G Base Station which is known as an eNode B ('evolved' Node B), and a 3G Base Station which is known as a Node B. Figure 21 illustrates two Standalone (SA) Base Station architectures, known as 'option 2' and 'option 5'.
In 5G SA architecture, the 5G RAN and its New Radio (NR) interface, consisting of gNodeB (gNB) macro cell base stations, is connected to the 5G packet core network and operates as a “standalone” entity. Click here for a larger version of this image.
By 2026, private 5G networks are expected to drive the need for an additional 500,000 base stations worldwide. Large enterprises, factories, and industrial zones are adopting private 5G to support automation, robotics, and AI-driven processes.
5G standalone (SA) is a completely new mobile network architecture. It enables all of the capabilities of 5G, given that it is not dependent on any existing 4G LTE infrastructure. 5G SA involves a new 5G packet core architecture, which means that 5G services can be deployed without pre-existing 4G LTE equipment in the network.
