§  Large operators continue to unveil their LTE and LTE-A plans

§  New devices defining mobile broadband success = New opportunities

§  Operators looking forward to SDN/NFV



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

C-RAN: Architecture Possibilities

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
