  • 7. 01 Main inputs from customer and industry trends 1. From the customer side, we expect current developments in devices to introduce new demands on networks and condition their future evolution. Video will be a major shaper of network needs. Video will be personalized and interactive. 2. Additionally, the network will have to manage a dramatically increased number of connected devices, as the Internet of Things / M2M market develops 3. Customers increasingly use our networks from wireless devices, connecting to either fixed or mobile networks seamlessly. Higher integration of fix and mobile access networks required from a customer perspective. 4. Network coverage and provided customer experience are becoming a key differentiation factor to compete. Indoor mobile customer quality and capacity to be the long-term main challenges Evolution to LTE and new rollout approaches based on higher capillarity and density access networks (Small Cells) to become the main network driver for the next yearsGlobal CTO 7Telefónica S.A.

  • 11. 03 LTE Small Cells Major ChallengesGlobal CTO 11Telefónica S.A.
  • 12. LTE HetNet Scenarios – Spectrum coordination03• Deploying of Small Cells in HetNet scenarios requires of tight interference coordination between macro and micro layers Long term view is that disjoint hard spectrum allocation between macro and micro is not desired but Rel.10 and Rel.11 functionalities shall play very relevant role • Carrier-aggregation based eICIC (frequency-based) • Non Carrier-aggregation based eICIC (time-based) eICIC will not be commercially available until 2013-14 timeframe, and even then: • Impact on legacy devices to be evaluated • Multi-vendor scenario not clearly envisioned (X2 inter-operability between vendors) Network Management SON Macro NM SON EPC Small Cell NM SON Required information for 1 macro/Small Cell coordination S1 is exchanged via X2 S1 S1 S1 X2 X2 X2 X2 1 Requires multi-vendor X2 X2 X2 InteroperabilityGlobal CTO 12Telefónica S.A.

  • 15. LTE HetNet Scenarios – SON03 • Self Operating Network is key for Small Cells rollout • From thousands of macros to hundreds of thousands of small cells implies a big Operational challenge. • SON to be key, and in a coordinated manner across all layers and within multiple vendors. • Automatic Cell Integration - Automatic Neighbor Relationship (ANR), inter-RAT for 2G, 3G and LTE, Automated PCI (Physical Cell Identity) selection • Capacity and Coverage Optimization – Load Balancing between layers, frequencies and technologies, mobility management, handover optimization, drive testing minimization, etc. • Energy efficiency – cell selective switch-off, transmission power dynamic adjustment, etc. • Interference reduction and coordination. • Network Operation & Maintenance • etc. SON features and enhancements are considered key for enabling efficient Small Cell rollouts Inter-vendor and multi-technology interworking requiredGlobal CTO 15Telefónica S.A.
  • 16. 03 Low-cost backhaul is key for Small-cells • Where Fibre is available and can easily be provided, it should be the primary backhaul option for microcells – long-term micro-cell backhaul capacity requirements are met. • Alternative low-cost backhaul is key for both targeted & blanket micro deployment => solution should meet today’s microcell bandwidth requirements while promising to meet future bandwidth requirements via hardware/software improvements required where access to low-cost fiber is not available • These solutions must also be easy to deploy i.e. minimal civil works at most installation of a CPE should suffice to set-up the backhaul A complete set of solutions to be available within Operators toolbox for efficient combination within small cells rollouts including fiber, copper and radioGlobal CTO 16Telefónica S.A.
  • 17. 03 LTE Small Cells infrastructure requirements vs. Mechanical and environmental integration is a key enabler for massive Small Cells Rollout !!Global CTO 17Telefónica S.A.
  • 18. 04 SummaryGlobal CTO 18Telefónica S.A.
  • 19. 04 Summary • Network society evolving from connecting places, to connecting people and now to connecting devices imposing significant challenges onto existing and future networks Number of simultaneous connections, capacity, QoE requirements, ubiquity, always- on, etc. Device evolution making it happen. • Within network strategy, higher capillarity RAN is a key element to cope with increasing requirements. • Nevertheless, significant challenges are still in place for efficient Small Cells rollout Spectrum management and interference coordination. Real and advanced Self-Organizing Networks integrating multiple layers. Backhaul alternatives. Infrastructure requirements.Global CTO 19Telefónica S.A.
