Summary

Next Generation RAN = HetNet • Multi-mode providing flexibility • Small cells for capacity & coverage

Topology alone is not enough • Blending of DPI & Wireless a must • Delivering the promise of SON

Still resource limited • Operator-controlled WiFi offload • Congestion, Femto, SLA, application-

aware
