Presentation @ MoMo Hyderabad in Decemeber. Discusses about wimax, alternatives to wimax, evolution of wimax. This needs a In Person Presentation Support.

1. Introduction to WiMAX
Satish, for MoMo Hyderabad Chapter

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. 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.

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. 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
