5G networks will feature virtualization, network slicing, new radio technologies, and software-defined networking. Key aspects include moving functions to the cloud edge through multi-access edge computing, converging heterogeneous networks through a unified radio access network, and applying adaptive network functions virtualization and software-defined management. This will allow for application-defined networks with end-to-end network slicing and separation of the control and data planes.
