  1. 1. Where Are We Going?Broadband/Mobile Broadband the 4th Utility LTE North America Dallas – 10th and 11th Nov 2010 Dr Shahram G Niri Director of LTE/SAE Global Strategy & Solution – NEC Europe
  2. 2. Table of Content Changing telecom industry (Services & Users, Networks) Diverged traffic and revenue growth Innovation & Reform Towards More Sustainability The need for Small Cells for capacity and performance in the future NWs Concluding remarksPage 2
  3. 3. Changing Telecom Industry Users will grow in importance  Customer delight is absolutely essential  Adopting new habits (e.g. social media, video addiction, ...)  More demanding on the quality, interactivity, personalisation Services will grow in multiplicity, diversity and richness  New services with the Internet at the heart the services More powerful and enabled devices Networks will grow in complexity  Hyper connectivity and increasing demand for capacity High capacity pipes with intelligent plumbing Self managed and automated networks Communication delivered through SW on standards / generic HW New business models will be in place New ecosystem & new player, and revenue models Communication networks to improve in intelligence, flexibility, automation, resilience, efficiency, speed, security, privacy, latencyPage 3
  4. 4. Diverged Traffic & Revenue Growth 50 Telecoms Price Development Significant growth in traffic while slow in revenue 40 Mobile Broadband  Ubiquitous Internet-based in hyper connected NWs 30  Hundred-fold increase in network flow brought by mass Euro/Month terminals and mass digital content 20  Users are spending more time on the phone & internet 10  Average household spending on communication falls  Consumer pay less while getting better value -> they 0 pay ~30% less than 5 years ago 2002 2003 2004 2005 2006 2007 2008 2009  Significant growth in traffic while slow in revenue Traffic Broadband/Mobile Broadband the 4th Utility Ubiquitous , high quality and affordable inter-based broadband essential to the functioning of modern life & society Gap Revenue From Kilo (103 ) bytes to Tera (1012 ) and Zeta (1021 ) bytes Time YET lower delivery cost per bit/per sub/per sq kmPage 4
  5. 5. Innovation & Reform Towards More Sustainability Cost Vs Revenue does not add up User experience at risk Limit/control it (e.g. Cap in flat rate) Bring the cost of it down (e.g. More efficient deliveries in radio, transport and core network, Optimizations and other means of traffic handling Turn it to revenue (e.g. Innovative solutions, New revenue streams and sources) Small Cell Deployments Alternative NW topologies LTE Small Cells Bigger, Smarter & Cheaper pipe Relay xG Cheaper NW operation Higher performance Femto 4G Pico 3G LTE Femto Intelligent Indoor Solution Micro 2G  New services & applications Macro 1G Cost saving and revenue generation Carrier Cloud  New service & revenue model  Service differentiation Cost optimization Lower cost & better performance and new revenue streams neededPage 5
  6. 6. Small Cells; Smart Way to Future Mobile Broadband LTE and HSDPA performance relative to Theoretical Limits 6.00 Spectrum is a finite resources, scarce & expensive 5.00 Achievable Efficiency (bps/Hz) LTE/HSPA link level spectrum efficiencies close to shannon limit HSDPA 4.00 theoretical limits LTE  Other factors such as Coding & Modulation, MIMO and 3.00 more spectrum contribute towards higher capacity – 2.00 Spectrum highest contributor! 1.00 0.00 -10.00 -5 0 5 10.00 15.00 Alternative LTE deployments (Small Cell - Pico Required SNR (db) /Femto cells) needed to avoid capacity shortfalls 30.00 Specturm Frequency reuse is the key to keep up with exponential 25.00 MIMO Modulation & Coding increase of traffic in the future with limited spectrum 20.00 availability Improves the QoS in the network – better user 15.00 experience 10.00 Allows for faster, more flexible, cheaper and easier 5.00 deployment and operation 0.00 GSM GPRS EDGE HSDPA HSPA+ LTE New network topologies and deployment strategy offer more gain than new technologies and HWPage 6
  7. 7. More Capacity & Better Performance (HSPA+ Vs LTE) 3G based NW could run out of capacity in 2010+ Network Capacity offered per device V.S. HSPA Forecast Traffic per device Network Capacity/Forecast Traffic (MB/month) HSPA+ needs major H/W 3000 upgrade to offer satisfactory performance & capacity; HSPA+ HSPA+ will not have 2500 More usage due to considerable improvements over improved performance HSPA and will have short life time 2000 LTE & HSPA LTE as an essential upgrade for all 3G operators will offer 1500 LTE with small better user experience (lower cells & Femto LTE & HSPA & latency, higher data rate, 1000 Femto better availability of higher data rate, better QoE at cell Traffic per edge) 500 device Alternative LTE 0 Potential deployments (Small Cell - Pico 2008 2009 2010 2011 2012 2013 2014 traffic /Femto cells) needed to avoid capacity shortfalls A constant challenge to keep ahead of future traffic increasePage 7 7 © NEC Corporation 2009
  8. 8. Think Big – Deploy Small Cells LTE LTE Macro deployment is not an option Coverage Layer  Will not offer the necessary capacity and performance 1 with large /macro cells  High cost of outdoor/macro radio 2 3 4  Data traffic /revenue mainly in hotspots & in-building  2G and 3G networks (already provide macro coverage) 1 Coverage Driven Macro LTE Small Cell as Overlay capacity and performance layer Macro deployment Micro  A sustainable solution towards ever increasing capacity  Pico demand Capacity Layer  Fast to deploy, cheap and easy to install and operate Femto  Start small and build as your number of users / traffic (Residential /SME) 4 increases 2 1 3  Revenue generation where the traffic is HSPA & LTE (Coverage Layer) LTE (Capacity Layer) 2 2G/3G Capacity Driven Hotspots and high traffic zones 4 LTE Hot spot/Metro 3 2 1 LTE Femto 3 New Business Driven LTE Femto Femto and hotspot islandsPage 8
  9. 9. More Network Capacity by LTE Small Cells Comparison of small Vs medium cell (DL) For the same traffic density, ISD 200m OMNI offers x 2.5 (x 3.5 in UL) user data rate on average, or x3 (x8 in UL) user data rate for cell edge user If targeting mean user data rate 10Mbps, 5%-tile user data rate 2Mbps, ISD 200m 2 OMNI offers ~4x system throughput The figures are MUCH higher if compared with larger cells Comparison of Macro & Macro+ Small (DL)  for the same traffic density mixed deployment offer ~2.5 x user data rate or ~2.4x user data rate If targeting mean user data rate of 10 Mbps, ~1.7x the mixed deployment scenario offer ~1.8 x Capacity capacity The figure are even higher for uplink (6X and 2.5 times) Significant improvement by deploying small cells in terms of cost per bit per Km2Page 9 9 Page
