By the end of this module you should be able to:
- Explain NSA and SA
- Identify the role of the 5G Core
- Avoid confusing 5G radio access with full 5G architecture
Non-Standalone
In common NSA deployments, 5G New Radio is added to an existing 4G EPC-based network architecture. This accelerated early 5G launches and delivered more radio capacity, but it did not provide the complete cloud-native 5G Core service model.
Standalone
5G Standalone connects 5G radio access to the 5G Core. The 5G Core introduces service-based network functions, native support for 5G QoS flows and the architectural mechanisms used for network slice selection and control.
Why it matters commercially
A device showing 5G may still be using an NSA service. Full slicing propositions normally depend on SA coverage, compatible devices, subscriptions, Core configuration and operator product support.
