    • LTE World Summit, Barcelona 2012 Fabricio Martinez, Director of Consulting, Global Operations1 © 2012 AIRCOM International Ltd
    • Agenda  Results background  Results  Lessons learnt  Q&A  AIRCOM2 © 2012 AIRCOM International Ltd
    • LTE is more than just IP3 © 2012 AIRCOM International Ltd
    • All LTE networks are not created equal  Deployments around the world have different conditions.  AIRCOM addressed the following spectrum bands: 700 MHz 1700 MHz 1800 MHz 2600 MHz  Bandwidth 10 MHz  FDD4 © 2012 AIRCOM International Ltd
    • LTE deployments around the world Involves different scenarios, strategies & regional challenges Provides a deeper understanding on what makes each roll out unique - and the lessons learned Multiple vendors5 © 2012 AIRCOM International Ltd
    • LTE Download results have a greater variance than Upload results Technologies - LTE, CDMA, UMTS, HSPA, GSM Time line - mid June 2011 to mid January 2012 Morphologies  Dense urban  Urban  Sub-urban Data calls FTP large file transfer in UL and DL to test retainability FTP small file transfer in UL and DL to test accessibility FTP & HTTP file transfer to test throughput ICMP /ping test to check round trip time / latency6 © 2012 AIRCOM International Ltd
    • LTE analysis  Inter cell distance/Network density/Number of cells  Modulation coding schema vs. CINR, BLER  Signal quality  Network performance in loaded vs. unloaded scenarios  In vehicle UE swap results  RTT/Latency average distortion  Network configuration (L3 signaling on broadcast)  Scheduler  Traffic shaping  MIMO analysis  HO decision process/IRAT analysis  Signaling latency7 © 2012 AIRCOM International Ltd
    • Stability – a key distinguish factor cross different scenarios and networks LTE Throughput Application TPUT [Mbps] 14.6 15.0 10.7 7.4 8.0 10.0 4.6 4.0 5.0 0.08 © 2012 AIRCOM International Ltd
    • Some comparative throughput similarities were identified against existing networks, example latency LTE Access Success Rates 100.0% 100.0% 99.8% 99.7% 99.8% 100.0% 100.0% 99.6% 99.8% 99.6% 99.4% 99.2% 98.7% 99.0% 98.8% 98.6% 98.4% 98.2% 98.0% RRC RRC SERVICE Intra HandOver CONNECTION CONNECTION REQUEST Success Rate Success Rate SETUP Success Success Rate Rate  Download speeds vary between 10 Mbps up to 52 Mbps (-47 dBm) Found CINR deltas between deployments of up to 10 dB for similar coverage environments.9 © 2012 AIRCOM International Ltd
    • Lessons learnt  Have a spectrum strategy - Buy or re-farm  Have an antenna strategy - separate or sharing  Understand LTE is IP but not only IP  Radio = Radio  Manage coverage vs. interference  Broadband delivery10 © 2012 AIRCOM International Ltd
    • AIRCOM has more than 15 years experiencehelping customers plan and optimise networks.  AIRCOM global independent provider of mobile network planning, optimization, management tools and services.  Offices in 15 countries across all regions  600+ customers  1000+ consulting engagements over the last 5 years  Market leaders of mobile planning and optimization tools (Analysys Mason report,2012).  Provide tools, vendor selection, planning, roll out and optimization (LTE Fast Track)11 © 2012 AIRCOM International Ltd
