    1. 1. Introduction to WiMAX Satish, for MoMo Hyderabad Chapter
    2. 2. What is WiMax? • WiMax (Worldwide Interoperability for Microwave Access) is a standards-based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DSL. • The technology is specified by the Institute of Electrical and Electronics Engineers Inc., as the IEEE 802.16 standard.
    3. 3. Relation of Wi-Fi and WiMax • WiMax eliminates the constraints of Wi-Fi. • Unlike Wi-Fi, WiMax is intended to work outdoors over long distances. • WiMax is a more complex technology and has to handle issues of importance such as QoS guarantees, carrier-class reliability, NLOS. • WiMax is not intended to replace Wi-Fi. Instead, the two technologies complement each other.

    15. 15. WiMAX vs. 3G, pros and cons • Cost – Lower equipment cost for WiMAX due to certified products (compare with WiFi) – WiMAX require new infrastructure while HSPA rides on UMTS • Coverage – Roughly the same coverage (average ~5 km) • Performance – Roughly the same performance (average ~2 Mb/s per user) • Market window – HSDPA launches in 2006 while HSUPA will come in 2008? – WiMAX standard set end of 2005 -> first products in 2007 • Acceptance – HSPA has a higher acceptance with mobile operator

    17. 17. WiMAX & India • WiMAX can play a major role in Indian economic growth – Can add 0.5 - 1% to the GDP • India needs to capitalize its core industries – Agriculture, Education, Medicine and IT • Can play a key role in technology standards and market requirements • Industry impact over $3Bn on infrastructure alone – Can lead the world in WiMAX deployments • WiMAX, 3G and WiFi will complement each other
    18. 18. Broadband Market Demand • Broadband deployment in India – Internet subscriber base from the ISPs is at ~ 7Mn – Always On high speed” connection (< 256 kbps) is only 0.86Mn – Broadband subscribers (>256kbps) is just 46,638 as on Dec ‘04. • In 2004, about 3.5Mn PCs sold; Growing at 35% YTY • Household PC market expected to grow to 20Mn by 2008 • Of 40.57Mn lines, 30.93 Mn is urban. Of which 10Mn usable copper plant
