Here, we can discuss the basic principles of network architecture and design, and we will go over the assumptions made and the options available that can be leveraged according to the use case at hand: Far-Edge Site Site 1 Site 2 ((g)) ((8)) ((g)) ((g)) Centralized Data Internet Far-Edge Site ((g)) ((8)) Center 5G Core Site 3 Network Functions ((8)) ((g)) ((g)) Near Edge Data Near Edge Data Site 8 Center 1 Center 2 ((g)) ((8)) Edge Cloud Site 4 ((g)) ((8)) ((g)) Edge Cloud Far-Edge Site ((g)) Site 7 Site 5 ((g)) ((8)) Site 6 ((8)) ((8)) ((8)) ((g)) ((8)) ((g)) Far-Edge Site Figure 2.2 - 5G data center design To design a 5G network, it is of the utmost importance to first decide on what use cases need to be supported. The design of the network will change according to the latency, reliability, and bandwidth needed to support a particular use case. In the example shown here, the use cases supported are enhanced broadband, Ultra-Reliable Low Latency Communications (URLLC), and the IoT, which means that this can be adapted to cover most applications. Let us focus on the main components of this design one by one - firstly, a far-edge site. This is basically the cell site in which the radio tower is erected. As most of us will know, an entire geographical area is broken down into cells in which radio base stations transmit. The hexagonal figures denote a combination of one or more cells, which can be connected to one or more RUs. Since this is close to the user accessing the network, it is known as far-edge. It should be noted that for some deployment options, a far-edge site can host both the DU and the RU. In other cases, the DU can be located in a local data center close to a collection of sites to aggregate the data. It is also possible to locate the DU, along with the CU, in a near-edge data center. The near- edge data center can also host the UPF for delay-sensitive applications. It is also possible to collocate the CU, DU, and RU in a far-edge data center. Hence, many different location configu
