All IP Interconnections Provides Many New Network Configuration Options
The radios (eNodeBs) talk to each other via IP
The eNodeBs talk to the core via IP
Even the elements of the core use IP
Implies many components can be separated by long distances

Industry Standard Interfaces Between the RAN and the Core
Industry standards define the S1 and X2 interfaces
Standard interfaces imply interoperability between one vendor’s RAN and another vendor’s EPC
Enables buying and selling spectrum AND RANs for the first time

•LTE specifies RAN sharing through Multi-Operator Core Network (MOCN)
• Spectrum can be shared or dedicated per operator
• Each operator’s EPC is connected to the shared RAN
• The end user’s experience is as if they were on their own network the entire time
