5G Network Technology FeaturesThe innovative features of 5G network can be summarized as diversified RAN networking, flexible function deployment, and on-demand slicing.
Support diverse networking mode: C-RAN, D-RAN, mesh,D2D, BS plug-inTo fit different 5G wireless scenarios
Plug-inDiversified RAN networkingFlexible function deploymentOn-demand slicing
Modularized Network function Network functions can be deployed flexibly based on NFV platform
One Logical Architecture, maps to multiple Service Slices. Orchestrating network resource on-demand for each slice.Isolated slices ensure efficiency, elasticity, security and robustness
