Moving to 5G requires new spectrum and technology
5G and all its promises couldn’t take place without three categories of spectrum and technology: new spectrum, spectral energy and efficiency, and new network architecture.
Understanding 5G Core
5G Core refers to 5G’s service-based architecture (SBA) that enables authentication, security, session management, and aggregation of traffic from linked devices. It’s a sophisticated integration of network activities with integrations based on http/rest APIs.
5G Core Elements – How 5G functions?
User equipment (UE) like 5G smartphones and 5G cellular devices link to 5G core through the 5G New Radio Access Network and then use DN for internet connections. User Plane Function (UPF) oversees transporting IP data traffic between UE and external networks.
Mobility Management Function (AMF) is the entry point for the UE connection. Based on the service requested, the AMF selects the right Session Management Function (SMF) to handle the user session.
The Authentication Server Function (AUSF) lets the AMF verify the UE authenticity and grant access to 5G core services.
Other functions provide the policy control framework, apply policy decisions, and grant access to subscription information to govern network behavior.
5G is an evolutionary step forward from 4G
Network traffic has grown exponentially, demanding 5G’s new architecture. Many new and exciting 5G services will be here in a matter of months. Industrial use cases and consumer examples already exist.
Moving from 4G to 5G offers improvements in latency, security, capabilities, and more. The 5G uses cases for specific industries offer a glimpse into what is possible. 4G was good and infinitely better than 3G. However, 5G has the potential to be great, transforming industries and improving the lives of billions.
