  1. Mobile WiMAX Roadmap for the Mobile Internet Revolution Siavash M. Alamouti Intel Fellow, Mobility Group CTO, Mobile Wireless Group

  2. Future Internet EconomyOECD Policy Brief, June 2008 The Internet “now underpins a range of new economic activities as well as activities and infrastructures that support our economies, from financial markets and health services to energy and transport”. “In the longer term, small wireless sensor devices embedded in objects, equipment and facilities are likely to be integrated with the Internet through wireless networks that will enable interconnectivity anywhere and at anytime”.

  3. Vision for Mobile Internet Transparent AffordableInternet AccessWherever*You Are Wi-Fi + Mobile WiMAX = 1st generation Mobile Internet WiMAX connectivity requires a WiMAX enabled device and subscription to a WiMAX broadband service. Availability of WiMAX is limited, check with your carrier for details on availability.

  4. What is the killer application? The Internet!

  5. Ingredients for Mobile Internet Success Affordable flat-rate charge Ubiquitous Connectivity Low-cost/Low Power PCs True Internet not Mini-Internets Simple Roaming Device Retail Model Open and PC-like Mobile Devices low cost modems

  6. Why do we need +2Mbps broadband? Internet is getting more complex with rich with multi-media • Web pages getting more complex • Avg web page size has tripled in past 5 years • +75% HTTP requests from images, up from 20% in ‘03 • +90% of web pages have images today • Video and HD are here • Average file size on the web = 10 MBytes • Video accounts for ~99% of all bytes transferred • And they are growing in size and length; 90% of videos are +3min, up from under 1 min in ‘97 • Quality is degrading • The more bandwidth, the more people benefit from the web Mobile Internet requires a Per-User Multi-Mbps Connection

  7. >100x higher data rate requirements 1-5 Mbps bursty traffic 10 Kbps constant rate Mobile Voice vs. Mobile Internet • A network optimized for mobile voice cannot handle high numbers of mobile Internet users • More spectrum needed for acceptable service level • More backhaul & different network architecture required Mobile Internet requires a technology revolution

  8. Mobile Internet Service Concept • Typical ARPU for 10 Kbps mobile voice service is ~$50/month in the U.S./$10/month in India • Internet requires a 1-5 Mbps class of service and an monthly rate of less than $30/month in the U.S. / $10/month in India •  Need to provide 100-500x the service level at ~1/2 the cost in the U.S. & the same cost in India!!!! Mobile internet requires a business model revolution

  9. Intel Accelerating Mobile Internet Globally

  10. Intel® Atom™ Processor Intel’s smallest processor built with the world’s smallest transistors Highest Performance in its class Ground-up Design for CPU & Chipset Intel’s lowest power CPU ATOM will revolutionize the PC industry to mass market affordability and mobility • HT Technology can add 200mW of power above quoted TDP for HT SKUs when multi-threaded applications are run. • Average power is defined as measured CPU power whilst running BAPCo MobileMark’05 Office Productivity suite on Microsoft* Windows* XP for a period of 90min at 50°C . • Idle power is measured when running Windows Vista in idle at 50C

  11. Intel WiMAX Products & Designs WiMAX/Wi-Fi Combo Modules WiMAX MIDs WiMAX Add-in Cards Approx indication of size Echo Peak* Baxter Peak* Dana Point* • 1st integrated Wi-Fi + WiMAX module • Highly integrated two chip solution • Small size & low power • Baxter Peak reference design * Internal code names for projects in development. Product names and plans are preliminary and subject to change.

  12. Technology Roadmap for Mobile Internet 2.0

  13. OFDMA + MIMO:Key Enablers of Mobile Broadband Internet OFDMA • Wider band of spectrum • 1000’s of carrier, sub-carriers • Flexible allocation of resources S1 S2 S3 MIMO • Multiple paths • Narrowband processing No more debates on modulation & multiple access

  14. Mobile Broadband Evolving to OFDM + MIMO 2010 2007 Cellular 3GPP 1G Analog 2G TDMA 3G WCDMA LTE 802.16d Broadband Wireless - WiMAX 802.16e 802.16m 802.11a/b/g 802.11n Wireless LAN - Wi-Fi OFDMA + MIMO New Spectrum All-IP Core Network

  15. Future Data Rate & Latency Comparisons of WiMAX and 3G Evolution Today

  16. WiMAX Direct Impact on 3G PC Modem Pricing Wireless Notebook Modem ASP Trajectory $150 Since Intel came out with Echo Peak 2.5-3G Cellular $111 ASP* 3 Chip .11N+.16E Single Chip .11N+.16E** WiFi .11ABG WiFi .11N $0 2006 2007 2008 2009 2010 *ABI Research, Q3’07 preliminary ** Intel Estimates

  17. 3G Embedded Module Pricing – Impact of WiMAX ABI Research: Expanding Cellular Broadband Connectivity to the Laptop, December 3, 2007 ABI Report: Cellular Modems and Mobile Broadband Connectivity, Q2 2008

  18. GGSN SGSN MGW PCRF SAE GW HSS OCS MME/UPE WiMAX or LTE = Same Level of Upgrade 2G, 3G Network (GSM, EV-DO, HSPA) 2G, 3G Core Network Upgrade core network to support more IP data traffic New data overlay network 4G Network: (WiMAX or LTE) All IP Core Radio Access Network (RAN): > 90-95% of new CapEx* Core Network Equipment < 10% of new CapEx* Both WiMAX & LTE require new RAN equipment & devices. Neither is “backward compatible” to 3G. Both can interwork well with existing 2G, 3G networks. * Intel estimates. Percentage varies based upon the operator’s existing network.

  19. Mobile WiMAX™ 2.0 (802.16m)300+ Mbps (2010/2011) 19 * Note: Actual mobility & throughput depends on environmental conditions and Service Provider provisioning. Aggregate peak sector throughput calculated using 20 MHz for DL. FDD support in 2010 Peak sector throughput over 300 Mbps DL* (in 20 MHz) TDD & FDD support Multi-carrier support; BW of up to 100 MHz Increased VoIP capacity Even lower link access latencies Enhanced coverage Enhanced multi-radio coexistence and inter-technology handover Integrated multi-hop relay Self-organizing base stations Increased mobility: Up to 350 km/hr*

  21. IEEE 802.16m Backward Compatibility • 802.16e/802.16m Mixed • Operate on the same RF carrier with same/different BW (a) • Support a mix of 16e & 16m MS on same RF carrier (c and e) • .16e MS same performance as16e BS (b=c) • .16m BS support handover of .16e MS to/from.16e BS (b   c) • .16m MS operate with .16e BS with same performance as.16e MS (b=d) • .16m able to disable legacy support for e WiMAX Release 2.0 (16m) will be tightly backward compatible to release 1.0 (16e) 21

  22. Summary Internet is a major driver of economic growth globally; mobile Internet is essential in accelerating this growth Mobile WiMAX is the first generation OFDMA/MIMO based cellular mobile radio technology - it’s here today leading the mobile internet revolution Mobile Internet requires a revolution in technology and business case; NOT an evolution of legacy networks and services OFDMA/MIMO is “the” radio access technology for Mobile WiMAX and next generation mobile internet technologies Mobile WiMAX has a “backward compatible” technology roadmap with IEEE 802.16m specified to meet the requirements of mobile internet in 2011 India is in a special position to adopt Mobile WiMAX (4G) today and lead the mobile internet revolution.
