2011 Broadband Tech Update to Electronic Engineers in the Philippines

  1. 1. Broadband Revolution Cocoy J. Claravall Business Products & Services
  2. 2. AGENDA • • • • • Industry Outlook Mobile Access Technologies 3GPP Roadmap Fixed Line Broadband Summary
  3. 3. Global mobile data traffic in 2010 (237 petabytes per month) was over three times greater than the total global Internet traffic in 2000 (75 petabytes per month).
  4. 4. Mobile Data Growth Per Region We are not far behind!
  5. 5. DEVICE DIVERSIFICATION The introduction of laptops, tablets, and high-end handsets onto mobile networks is a major generator of traffic, because these devices offer the consumer content and applications not supported by the previous generation of mobile devices. 2009 2010 2015 Device Type Nonsmartphone E-reader Smartphone Portable gaming console Tablet Laptop and netbook M2M module 1.5 5 35 N/A 28 1,145 3 3.3 11 79 250 405 1,708 35 54 245 1,272 879 2,311 6,522 166
  6. 6. Main contributors to mobile data growth • As mobile network connection speeds increase, the average bit rate of content accessed through the mobile network will increase. • As the battery life of mobile devices improves, mobile minutes of use will increase. • As mobile network capacity improves, operators are more likely to offer mobile broadband packages comparable in price and speed to those of fixed broadband, thereby encouraging mobile broadband substitution. • The shift towards unicast from broadcast will affect mobile networks as much as it will affect fixed networks.
  7. 7. Video is driving user traffic …
  8. 8. World Trend of Mobile Users Population • Fast increase of 3G/HSPA/HSPA+ users due to high smartphone penetration • Stable user base in GSM/GPRS/EDGE • Mobile WiMax is not growing as fast due to slower development in Wimax standards and smaller deployment scale compared to other technologies • User base in 3GPP-family technologies still dominate most parts of the world; easier roaming

Comparison of WiMax 2 and LTE Development Timelines The rapid growth of broadband usage driven by flat rates, multimedia applications , smart phones, connected devices, social networking poses capacity challenges for today’s broadband operators especially in high density urban areas. If 3G network is used to provide for both Mobile data and DSLsubstitute, then this challenge aggravates. Up to 21 Mbps WiMAX offers operators another option to not only add capacity to the access network to meet current demands and to segregate fixed broadband usage from mobile data usage where DSL is not available. The other option of course is to wait for LTE . Broadband Wave rising rapidly & steadily now Chart Source : WiMax Forum, Nov 2009
