Mobile WiMAX Roadmap for the Mobile Internet Revolution Siavash M. Alamouti Intel Fellow, Mobility Group CTO, Mobile Wireless Group
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”.
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.
What is the killer application? The Internet!
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
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
>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
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
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
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.
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

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.
