  • 15. Carrier Aggregation Aggregate multiple carriers Contiguous & non-contiguous Transmission BW up to 100MHz Peak data rate 1Gbps Primary & Secondary Cells Small Cells serving as Secondary Cells for CA 3G 5MHz LTE 20MHz LTE-A 20MHz … LTE-A 20MHz Radisys Corporation Confidential 15
  • 16. SON (Self Organizing Networks)  Centralised • SON solutions where SON algorithms are executed in a centralized entity – say, OAM • In such solutions SON functionality resides in a small number of locations • More control for operator (less scalable)  Distributed • SON solutions where SON algorithms are executed at network element (eNB / HeNB) • In such solutions SON functionality resides in many locations • Less control for operator (most scalable)  Hybrid • SON solutions where some of the SON algorithms are executed in the OAM system while others are executed at the network element level • Best option, most suited for adhoc networks (for femto / small cells) • Operator can “move” to Distributed option as and when they have more confidence on multi-vendor SON algorithms Radisys Corporation Confidential 16
  • 17. HetNet : Impact on Ecosystem Portfolio of Products • Small to Macro Requirements Evolving – Flexibility A Must • Customizable to meet operator use case SON & IOT Key • Must enable macro to small cell coordination Wifi + Licensed Integration • Seamless, coordinated, optimized Cost & Performance Table Stakes • 3G HSPA+, LTE & Multi-Mode Radisys Corporation Confidential 17
  • 18. Evolving Business Models Ecosystem driving innovation on new business models 1. Managed services - maintain hetnet’s network. 2. RAN Sharing / Backhaul sharing 3. SaaS - Small cells As A Service 4. New Charging and Policy mechanisms Revenue Opportunities • Application specific offload • Innovation in Apps by developers • Rent Small Cell Capacity • Policy Enforcement Radisys Corporation Confidential 18
