NG-RAN: Unveiling the Next Generation Radio Access Network
At the heart of 5G lies NG-RAN, a revolutionary radio network that propels us into the future. NG-RAN comprises two types of base stations: G node B and NG enode B. You might have noticed these towers while driving around or in your local area. These towering structures, also known as cell towers or base stations, play a pivotal role in facilitating mobile connectivity.
Within these base stations, you’ll find the crucial components responsible for connecting your device to the mobile network: the radio network antennas. These antennas, usually in the form of vertical rectangular structures, ensure that your phone receives a stable and robust mobile signal. So, next time you face connectivity issues, it might be worth checking your proximity to these radio network antennas.
Understanding Radio Access Networks
Now, let’s take a closer look at the concept of a radio access network (RAN). The RAN serves as the bridge connecting all cellular devices, such as mobile phones, broadband routers, tablets, smartwatches, and IoT devices, to the mobile network. To achieve this seamless connectivity, 5G and RAN employ a radio access technology called OFDMA (Orthogonal Frequency Division Multiple Access).
To better visualize the role of RAN, consider the diagram above. Within the comprehensive mobile network architecture, RAN takes center stage. It utilizes radio waves (RF waves) to establish a wireless connection between mobile devices and the cell towers. The cell towers, in turn, are linked to the mobile core network, facilitating communication with external networks like PSTN, ISDN, and the internet.
NG-RAN in the Bigger Picture
Zooming in on NG-RAN itself, we can observe its specific placement in the mobile network architecture. Within the overarching network, NG-RAN is represented by a red rectangle. While the diagram may seem busy, focus on this crucial component encapsulated within the red rectangle: the NG-RAN.
As we delve deeper into NG-RAN, we encounter the base station known as the GNB (G Node B). GNB serves as the next-generation node B, and it encompasses two entities: the GNB Central Unit (CU) and the GNB Distribution Unit (DU). Although both units can coexist within the same location, it is also possible to position the DU closer to the end-user, ensuring optimal performance.
The DU handles real-time scheduling functions, while the CU focuses on non-real-time tasks. This distribution of responsibilities ensures efficient operations and enhances the overall network performance.
