SA provides the full suite of 5G features, including enhanced security, network slicing, and edge computing, but requires a more significant investment in infrastructure.

5G Network Components

The 5G network is composed of three primary components: the core network, the radio access network (RAN), and the user equipment (UE).

5G Core Network (5GC): The 5GC is the brain of the 5G network, responsible for managing user sessions, controlling network resources, and providing core network services. It handles data routing, authentication, and other essential functions, enabling seamless communication between devices and applications.
Radio Access Network (RAN): The RAN connects user equipment to the 5GC, providing the wireless interface for data transmission. It consists of base stations, antennas, and other radio equipment responsible for signal processing and transmission. The RAN is the crucial component responsible for delivering high-speed data rates and low latency.
User Equipment (UE): This refers to any device that connects to the 5G network, such as smartphones, tablets, laptops, and IoT devices. The UE interacts with the RAN through the radio interface, receiving and transmitting data to the 5GC.

Key Technologies Enabling 5G

Several key technologies contribute to the performance and capabilities of 5G, including:
