Why Change The RAN?
§ HetNet Deployments are picking up but not without challenges
Cost and complexity of network
planning
When it comes to capacity management, redirection
alone is not sufficient
C-RAN promises improved network efficiency, with lowered TCO,
to improve monetization of mobile broadband

Scenario #1
• All functions centralized
§ Scenario #2
• All functions centralized except
PHY
§ Scenario #3
• All functions centralized except
scheduling and PHY
• BBU, Time critical L2 co-located
§ Scenario #4
• Only L3 functions centralized
• L2 and PHY distributed
• BBU, L2 co-located
