  • 1. The ultra-efficient network factory: network sharing andother means to leapfrog operator efficiencies.Broadband MEA, March 26th 2012, Dubai, UAE.Dr. Kim Kyllesbech Larsen,Technology, Deutsche Telekom AG.
  • 2. Deutsche Telecom … Mobile Business … 100+m mobile subscribers over 100+ thsd radio nodes. GSMEDGE, UMTSHSPA+ (42), LTE @ 800MHz2.6GHz & WiFi. Network partnerships in UK, Poland, Cz, Austria, … Last 10yrs more than doubled the size of its mobile networks …. Dr. Kim Kyllesbech Larsen, Broadband MEA, March 26th 2012, Dubai, UAE. 2

  • 4. The profitability challenge…NOT only a problem for mature markets! Aug. 2011 China Unicom, at the moment only Chinese carrier selling Feb. 2011 Tellabs reports iPhone in the country, H1 profit mobile operators profitability down 9% …. has been struggling challenged within 2 - 3 to grow its profitability due to years, and mobile internet is heavy subsidies2. forcing operators to transform their networks and business models 1. Nov. 2011 Bharti Airtel Nov. 2011 South Korea’s KT reports profit dip again, in the reported a 41% slump in Q3 net seventh quarter4. profit , as a result of discounts and other initiatives to lure more smartphone users6. Oct 2011 China Telecom Corp reported third-quarter profit that Oct. 2011 Idea Celluar profit missed analysts estimates, as add down 40.3% QoQ, despite itional 3G users increased the comp revenue increases of 13.2%5. anys costs3 1 Tellabs; 2 Reuters; 3 China Daily; 4 Business Review India; 5 MediaNama; 6 Telecom Asia; Dr. Kim Kyllesbech Larsen, Broadband MEA, March 26th 2012, Dubai, UAE. 4
  • 5. Mobile growth in perspective.Globally Cost per Customer increased 8×, ARPU remainedconstant (or declined) with a doubling of mobile subscriptions1. Example: Emerging Asia Profitability drop of almost 10%. Opex growth faster than Revenue. Highest ARPU YoY decline. ca. 70% mobile penetration today. Main 3G growth still ahead. Emerging Market Growth on expense of profitability?  Long-term outlook could be troublesome. 1 Looking over the period 2005 to 2011.

  • 9. Backhaul requirements will pressure the Economics.HSPA+ & LTE’s power-full air-interface, i.e., 100+ Mbps, willrequire extensive backhaul fiber deployment. LTE air-interface 30mean to 100+peak Mbps (per sector) 100 Gbps Evolved eNode DWDM Packet Core 100 GbE FTTS1 100+ Mbps eNodes per element 32:1 320:1 3200:1 BH Throughput 3+ 32+ 320+ In Gbps Illustration Dr. Kim Kyllesbech Larsen, Broadband MEA, March 26th 2012, Dubai, UAE. 9
  • 10. The backhaul challenge … macro vs micro.Distribute mobile broadband traffic differently. Illustration LTE provides up-to 100 Mbps AP (e.g., WiFi / Femto,..) per sector Node FTTS1 100+ Mbps 100+ to 40 Mbps 300 – 7,000 active devices Home Environment per macro-cellular node with ca. 2.3 people per Home 1 (dense-urban / urban) connected to Fiber, Cable or VDSL. 100+ Mbps Up-to 100+ Mbps shared with shared by up to 7,000 devices. 2+ people. 1 Average for Western Europe.

  • 15. Anatomy of network sharing.RAN sharing guaranties competitive differentiation, operatorindependency and vast consumer quality improvements.• Sharing: Costly Radio Access Network infrastructure will be shared,• Not shared: All core network and service infrastructures that provides respective customers with differentiated services, applications, handsets, rate plans, etc.• Result: A network with greater capacity (i.e., instant cell split) and improved coverage.
