  1. 1. The Smart Way To LTE Dr Shahram G Niri - NEC Europe Broadband World Forum 2009 - Paris
  2. 2. LTE - Realizing True Mobile Broadband •Broadband • Everywhere Mobility •Mainly in Buildings •Affordable Mobile Broadband: A reality today and to be the dominant means of Mobile Broadband Mobile broadband connectivity in the near future But will need Telephony Internet Broadband improvement in capacity, coverage, performance and Today ~ 4 Billion operation yet at a lower cost! Today ~ 1.2 Billion Today ~140 Million <80% 3GPP family • Lower TCO (LTE Vs HSPA+) Traffic Cost Aggressive growth HSPA+ needs major H/W upgrade to offer Upgrades Life time satisfactory performance & capacity; may have Moderate growth short life time If aggressive mobile traffic NW capacityPerformance • LTE offers better user experience (lower latency, higher data rate, better avaibility of higher data rate, better QoE at cell edge) LTE Operation •Technology leadership HSPA+ HSPA Time Higher revenues for 1st mover & Followers (in order to remain competitive) When • Traffic per sub & number of connections and therefore capacity demand LTE: A cost effective, much better performance & •Spectrum availability & country regulatory situation future proof technology for true Mobile Broadband •Service provision strategy •Competitors’ movements 2 © NEC Corporation 2009
  3. 3. LTE – A Must Deploy Technology With LET Femto/small cells Mature LTE Mobile Network Mature 3G/HSPA Traffic Growth Mature GSM Early GSM Early 3G Early LTE 1990 2000 2005 2010 2015 2020 2025• Data traffic to increase exponentially 40% 35% Site• Extra capacity not required everywhere - The data traffic and data Radiorevenue is generated mainly in hotspots & in-building 25% Backhaul• The cost of outdoor/macro radio is high TCO breakdown• Problematic indoor coverage at high frequencies using macro• 2.6 GHz not suitable for indoor and costly for coverage Public transport Public 4% outdoors• Need to operate 3 NWs for some time BUT managing 3 NW will be Public 10%costly and complex -> The 3rd NW will need to be cheap, easy to manage indoors 10% 41% Private Homeand fast to deploy transport Wireless broadband 12% Work digital connected home LTE to start in hotspots, high traffic zones & 23% enterprise/residential Femto followed by Mobile usage in Western EU nationwide coverage at later stages 3 © NEC Corporation 2009
  4. 4. Think Big – Deploy Small Cells Why LTE deployment derivers• Use 2G and 3G networks (already provide macro coverage)• Use 2.6GHz & deploy LTE initially for high data traffic hot spots 1 4• Use an overlay cheap , easy to install and operate micro/pico /Femto LTE• Address indoor coverage and capacity with LTE Femto enterprise 2• Improve macro (HSPA) coverage by overflowing the traffic to LTE 3• Use Digital Dividend later on & when the older technologies phase out for LTE macro 1 Capacity Driven Benefits Hotspots and high traffic zones• Invest where the traffic and hence the revenue is• Improve your overall data traffic capacity and performance 4• Start small and build as your number of users / traffic increases 3 Future Outlook 2 1• 2G&3G for ubiquitous voice & HSPA mainly data 2G/3G New Business Driven 2 HSPA Femto and hotspot islands LTE• 2G&3G for Voice & HSPA for ubiquitous data & LTE for data 1 LTE 3 4• 2G OR 3G for voice , HSPA for LTE 2 Femto ubiquitous data & LTE for data Coverage Driven LTE 3 Macro deployment 4G 4 © NEC Corporation 2009
  5. 5. LTE (eNB) & SAE (ePC) Deployment Options Upgrade eNBUpgrade - SW & HW• Most current NBs & xGSNs will not allow for a cost effective upgrade LTE RF RF• Different/new requirements & no room for compromise 3G• Technology limitations (e.g. processing, memory, power ) BBU BBU• Risks of impacting existing 2G/3G performance• Limit the choice of selecting the right vendor (best of breed Vs existing) Overlay LTE LTE Femto New -> OverlayNew eNB & ePC - Dedicated eNB & ePC for high capacity & ePC SW performance• Freedom in terms of product form factor, vendor & deployment type 2G/3G HW• Freedom in selecting best of breed• Min impact on the existing NW performance S/P GW MME• Faster rollout and suitable for initial deployments• Choice of new platform independent of the existing platforms S/P GW• various deployment options xGSN MME LTE as an overlay deployment initially: xGSN A fast, easy and less costly deployment option 5 © NEC Corporation 2009
