  • 1. Seminar Presentation on WiMAX Connecting The Next 5 Billion People PREPARED BY: Yogesh Maurya III Year(IT) Roll No-0806313057
  • 2. Agenda
    • Introduction
    • Architecture of WiMAX
    • Spectrum Allocation
    • LOS Vs NLOS Technology
    • Adaptive Modulation
    • Connecting to WiMax
    • WiMAX Security Challenge
    • Wimax Vs WiFi
    • Conclusion
  • 3. Introduction
    • Next generation of Wi-Fi
    • Wireless wide area n/w technology for broadband internet access.
    • WiMAX is a fast-emerging wide-area wireless
    • broadband technology
    • WiMAX (Worldwide Interoperability for Microwave
    • Access) forum is a non-profit corporation formed to
    • help promote and certify the compatibility and
    • interoperability.
  • 4. IEEE Standards
  • 5. WiMax Architecture
  • 6. Contd……
    • Mobile Stations (MS) used by the end user to access the network.
    • ASN comprises one or more base stations and one or more ASN gateways
    • CSN which provides IP connectivity and all the IP core network functions.
    • The BS is responsible for providing the air interface to the MS.
  • 7. Demand for Wireless Broadband
    • Telemedicine
    • Teleworking
    • E-Government
    • Agriculture
    • Distance learning
    • Public safety
    • National security
    • E-commerce
    • Entertainment
    • Applications for
    • persons with disabilities
    • Utility applications
    • Small business
    • assistance
  • 8. Stay Connected
  • 9. Spectrum
  • 10. Spectrum Allocation
  • 11.
    • WiMAX operate in two frequency bands.
    • Operates in two separate frequency bands
    • 2-11 GHz and 10-66 GHz
    • Licensed (2-11 Ghz) spectrum.
    • Unlicensed (5-8 Ghz) spectrum.
  • 12. LOS Fresnel Zone
  • 13. NLOS Propagation
  • 14. NLOS
  • 15.
    • Promises to deliver high data rates cheaply to remote regions
    • At the higher frequencies, line of sight (LOS) is required – point-to-point links only
    • In the lower region, the signals propagate without the requirement for line of sight (NLOS) to customers
  • 16. Adaptive Modulation and Coding
  • 17. Digital Modulation
  • 18. BPSK & QPSK
  • 19. FDM with Nine Sub-carriers OFDM with Nine Sub-carriers OFDM
  • 20. OFDM OFDM with 256 Sub-carriers
  • 21. Connecting to WiMax Gateways Dongles Mobile Phones
  • 22. WiMAX Security Challenge
    • Client impersonation
    • Server impersonation
    • Message tempering
    • Session tampering
    • DoS attacks
  • 23. WiMAX Vs WiFi
    • WiMAX is more secure
    • WiMAX is faster
    • WiMAX has longer range
    • WiFi uses 802.11 Standard
  • 24. Markets Targeted By WiMAX
  • 25. Conclusion
    • WiMAX could bring broadband access into the homes
    • and businesses of millions of people in rural and
    • developing markets.
    • Portable Internet a reality
    • End-users to enjoy an “Always Best Connected”
    Thank You!!!
