Technologies
Softwarization and Virtualization
In the direction of improving resource utilization, there are also concepts of SDN and NFV.SDN: three layers (infrastructure layer, control layer and application layer) + various APIs for the communication between layers.
Infrastructure
Comprises network devices and equipment
1 Control
Provides SDN control software and network services for addressing the requirement of the applications
2 Application
Provides open API links with other application or system

15%
Spectrum increase
Spectral efficiency increase
More cells
Energy savings from sharing physical infrastructure is up to 60%The constant decrease of the cell sizes leads to cheaper cells and less expensive production Decrease in size → decrease in cost of production machineryThe potential of the softwarization and virtualization of network functions → more dynamic allocation of inter-network resources
5G goal of 1,000x increased capacity
21
Benefits
Network Providers must co-operate to share the infrastructureHistorically this has led to excessive royalties and fees being demanded by the regional/national monopoly if it is a private entity
Spec02
The use of a wider range of bands requires licensing and strong spectrum management
Cell03
Increase in the number of small-sized cells, with the goal of obtaining ultra-dense networks
• Investment required to increase production of cells and development of smaller cells
• Require new permits to set up smaller cells which can be very costly
