• Two logical network layers, a radio network
(RN) that provides only a minimum set of
L1/L2 functionalities and a network cloud
that provides all higher layer functionalities
• Dynamic deployment and scaling of functions
in the network cloud through SDN
and NFV
• A lean protocol stack achieved through
elimination of redundant functionalities
and integration of AS and NAS
• Separate provisioning of coverage and
capacity in the RN by use of C/U-plane
split architecture and different frequency
bands for coverage and capacity
• Relaying and nesting (connecting devices
with limited resources non-transparently to
the network through one or more devices
that have more resources) to support multiple
devices, group mobility, and nomadic
hotspots
