  1. Liquid Radio – making waves in the future of communications Orlin Nedialkov April 2012, Sofia

  2. How to offer the network capacity efficiently for the big regular moves? Spring, Autumn, Winter Summer

  3. How to bring capacity to the places where heavy user are? Hot spots Voice and basic data Business district, airport Suburban, rural, small city

  4. Nokia Siemens Networks answer - Liquid Net: unleashing the broadband opportunities of existing networks What Unleashes frozen network capacity into a reservoir of resources that can flow tofulfill unpredictable demand • How • Self-aware and self-adapting • Software-defined applications on multi-purpose hardware • Inter-linked architecture • Evolutionary • Why • Higher network utilization: Up to 65% capacity gain in radio cells • Lower operating costs: Up to 15% core network savings through automation • Superior customer experience: Streaming optimization can halve video standstills • Business potential: Increase revenues by up to 10% with temporarybroadband upgrade

  5. The business context: four broadband challenges in an increasingly dynamic world Location and context Unpredictable data growth Win new revenue How to deliver a compelling and profitable customer experience? Revenue Data volume Time Time Leverage technology advances Hardware Hardware Software

  6. Demand is unpredictable Different times, various locations Sudden peaks Suburbs City Residential 12am T ime 12am Up to 80% idle capacity Up to 50% idle capacity Content Users Radio Core

  7. Liquid Net comprises solution components in all network domains Liquid Net Liquid content and traffic management for superior customer experience and newrevenues Intelligent Broadband Management Integrated QoS and Content Delivery Network Liquid Radio Baseband Pooling Single RANFlexi MR Antenna Unified and SON-enabled HetNet Liquid Core Core Virtualization SON for Core Liquid Transport FlexibleOptics IP Transport Integration Intelligent Control Liquid resource allocation for flexibility and enhanced efficiency

  8. Liquid Radio - The solution

  9. Liquid Radio: Redefining base station-based architecture Conventional Radio Liquid Radio Flexible sharingof resources ‘One size fits all’ architecture Baseband Pooling Static cells Single RAN Active Antenna System Automated multi-radiobeam forming Fragmented radio access Coordinating macro and small cell layers Unified and SON-enabled HetNet

  10. Liquid Radio: Demand is like a wave in modern networks Hotspot demand is rapidly outpacing the ability to add capacity Excess Bandwidth Demand in 20 Km² business or downtown area (GB/hour/Km²) over average bandwidth demand Busy hour Capacity demand at a given time Network coverage Source: iGR, 2012

  11. Liquid Radio: Key elements and what’s new Single RAN - Active Antenna Systems Baseband pooling Unified and SON-enabled Heterogeneous Networks Small Cells Macro Cells Cell 1 Cell 2 Small cells strategy SON for small cells SON for HetNet • SON for AAS: automated beam forming for dynamic cells based on time of day or demand Flexi Zone:new small cell architecture Baseband pool

  12. Liquid Radio: World-first vertical sectorizationFlexi Multiradio Antenna System Active Antenna with beam forming Active Antenna System Automation Radio cells defined by software (on/off) Vertical beam steering for best user experience Compact, power efficient, easy to deploy 65% more capacity30% more coverageat same time Lowest TCO – 35% saving

  13. Liquid Radio: Baseband Pooling - static capacity becomes fluid and adaptive • The challenges . . . • The ‘ebb and flow’ of demand leaves capacity stranded in conventionally dimensioned networks • 2G, 3G, LTE and LTE-A coexist in the same sites • Introducing small cells addresses just one aspect of congestion – fronthaul, backhaul and core need to be considered too • Signal quality does not equal throughput and thus QoS/QoE LTE-A LTE HSPA+ GSM

  14. Liquid Radio: Going fluid from today’s architectureOnsite and off-site baseband pooling Radio Fronthaul Baseband Base station Distributed RAN BB A baseband pool for each base station, with baseband shared across sectors and radio technologies RF Multiradio and software defined hardware platform BB RF Short distance A baseband pool serves several connected baseband units that dynamically serve several remote RRUs Small Cells: Flexi Zone Macro Cell: Proof of Concept Centralized RAN RF BB RF Long distance

  15. Liquid Radio: Unified and SON-enabled Heterogeneous Networks • The challenges . . . • High complexity • Multi-RAT, multi-layer, multi-vendor • Thousand of multiple variables • Increasing level of expertise required by systems demands more human interaction • Introduction of smaller cells into already complex network environment • Capacity in the right technology layer • Challenging interoperability

  16. Liquid Radio: Unique 360 degrees strategy and portfolio Macro Modernize, upgrade, refarm and squeeze spectrum AAS SON Small cells volume Macro Base Station SON for Radio SON for Core Capacity offload Enhance coverage Small Cells Hot Zone In-building Rural Hotspot 2012 2013
