  1. 1. ITU Regional Workshop on IMT Da Nang, VietNam; 7-8 June 2010 HSPA+ and LTE Technology Development Dr Patrick Tsie Senior Director, Technical Marketing Qualcomm International Inc International Telecommunication Union
  2. 2. HSPA+ and LTE Technology Development June 2010 2
  3. 3. >1B 3G Wireless Subscribers Today ~2.8B 3G Subscribers by 2014 ~4.8B Wireless Subscribers Note : 3G includes CDMA2000, WCDMA and TD-SCDMA Source: Wireless Intelligence estimates as of Apr 19, 2010 for the quarter ending Mar 31, 2010,; number of unique wireless connections. 3 Wireless Intelligence estimates for CDMA2000 1X/1xEV-DO subscribers do not include Wireless Local Loop
  4. 4. Mobile Dominates Global Broadband Subscriber Growth—Overtakes Fixed in 2010 Subscribers* (Millions) >70% of total broadband subs 2500 will be mobile 2000 Fixed 1500 Mobile 1000 500 0 2008 2009 2010 2011 2012 2013 Total mobile broadband subscriptions are projected to be ~2B by 2013 Note: Mobile Broadband includes EV-DO family, HSPA Family, TD-SCDMA and LTE; * number of unique wireless connections Source: Strategy Analytics (May09), Informa (Oct09), Wireless Intelligence (Oct09), Yankee (Jun09) 4 Fixed Broadband includes: major variants of xDSL, FTTx, and fixed wireless broadband , Source: Informa (Aug09)
  5. 5. Acceleration of 2G to 3G Migration - Subscribers Subscribers* (Millions) 4,500 GSM 3G ~2.8B 3G 4,000 3,500 3,000 2,500 2,000 1,500 1,000 500 0 2008 2009 2010 2011 2012 2013 2014 3G subscribers surpassed 1B in mid-march 2010 From 2010 onwards, 3G is expected to contribute more net adds than 2G GSM subscribers estimated to flat-line in 2011 and decline from 2013 onwards Note: 3G includes CDMA2000, WCDMA, TD-SCDMA 5 Source: Wireless Intelligence estimates as of April 19, 2010 for quarter ending March 31, 2010, *number of unique wireless connections
  6. 6. Mobile Technology Evolutional Roadmap Excellent Mobile Broadband Enhanced User Experience Voice and Full Range of IP Services Improved voice and data capacity CDMA2000 1X Advanced 1X Simultaneous 1X Voice and EV-DO Data Rel. 0 Rev.

  7. 7. HSPA+: A Strong Evolution Path For Peak Throughputs 168 Mbps HSPA+ R10: 20 MHz Multicarrier • Expands HSPA+ to 20 MHz deployments • Evolution to femtocell networks HSPA+ R9 & R10: Expands Multicarrier HSPA+ R9: Expands 10 MHz Multicarrier 84 Mbps • Enhanced performance in 10 MHz • Uplink multicarrier • MIMO support with multicarrier • Multi band multicarrier—aggregation across bands HSPA+ R8: 10 MHz Multicarrier (dual carrier) 42 Mbps • Enhances broadband experience •Doubles data rates to all users 28 Mbps • Doubles bursty application capacity • Standardized femtocell support 14.4 Mbps HSPA+ R7: Next Gen. Performance Today • Doubles data capacity 23 Mbps • More than doubles voice capacity • Similar HSPA+ and LTE performance 5.7 Mbps 11 Mbps • The natural evolution at a lower cost 384 Kbps Rel - 5 Rel - 6 Rel - 7 Rel - 8 Rel - 9 Rel – 10 HSPA HSPA + Notes: R8 will reach 42 Mbps by combining 2x2 MIMO and HOM (64QAM) in 5 MHz, or by utilizing HOM (64QAM) and multicarrier in 10 MHz. R9 combines multicarrier and MIMO in 10 MHz to reach 7 84 Mbps peak rates. Uplink multicarrier double the uplink peak data rate to 23 Mbps in 10 MHz in R9. R10 expands multicarrier to 20 MHz to potentially reach 168 Mbps when using MIMO.
