Introduction to WiMAX Presentation Transcript

  • 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.
  • 4. 3GPP 3GPP2 EVOLUTION EVOLUTION REVOLUTION Advancing Wireless WiMAX CDMA 1X EV-DOr0 EV-DOrA EV-DOrB WCDMA HSDPA HSUPA 4G 802.16e EV-DOrC LTE
