• OPEX dominates expenses

− Power bill − Site acquisition/renting costs

increasing

• Insufficient Flexibility and Scalability

− Overprovision capacity to handle load dynamics

• Office vs Residential area/time

− Proprietary Custom solution

• Unable to support diverse application services

− Challenge to launch different network configurations

• Self-Organizing Networks, New Spectrum & Access Technologies

Virtualized RAN Example

• Centralized Processing Capability

− Traffic and Load-balancing − Network optimization

• Virtualized Processing

− Reuse or resell unused capacity − Value-added (e.g. location based) services

• Low-cost radio end-points

− Independent processing for each end-point

improves capacity over traditional DAS

− Connectivity with fiber, radio fronthaul or

Ethernet
