  1. Wimax (802.16) A Road to Mobile Life

  2. Content • History Of Wireless • Wimax • Advantages Over Wifi • MAC Structure • Usage Areas • Competitors • Conclusion

  3. Content • History Of Wireless • Wimax • Advantages Over Wifi • MAC Structure • Usage Areas • Competitors • Conclusion

  4. Modern Era History of Wireless • Radio- Jagdish Chandra Bose and Guglielmo Marconi. • Wireless- First patent by Nikola Tesla. • Wireless- Term used for everything for long time • Wireless- is a method of communication that uses low-powered radio waves to transmit data between devices. • Low Powered – Free • High Powered – Government Regulated

  5. Some Wireless Standards • Bluetooth • DECT (Digital Enhanced Cordless Telecommunications) • DSRC (Dedicated Short Range Communications) • HIPERLAN • HIPERMAN • IEEE 802.11 • IrDA • RFID (Radio Frequency Identification) • WiFi • WiMAX • xMax • ZigBee

  6. Content • History Of Wireless • Wimax • Advantages Over Wifi • MAC Structure • Usage Areas • Competitors • Conclusion

  7. Wimax • Worldwide Interoperability for Microwave Access • A certification mark for products that pass conformity and interoperability tests for the IEEE 802.16 standards • Run by Wimax Forum

  8. Content • History Of Wireless • Wimax • Advantages Over Wifi • MAC Structure • Usage Areas • Competitors • Conclusion

  9. Advantages Over Wifi • Improved Performance • Much Greater Distances • Much Better MAC • LNOS Ability

  10. Content • History Of Wireless • Wimax • Advantages Over Wifi • MAC Structure • Usage Areas • Competitors • Conclusion

  11. New MAC Structure • A Regular Wifi Uses Contention access Which means competing for AP. • Wimax uses scheduling MAC Much Better for QOS required services EX: VOIP , IPTV • Mesh Networking Subscriber station and Base station at same time • OFDMA

  12. New MAC Structure (cont.) • Supports ATM • Packet based Control • MAC is flexible enough to efficiently carry any traffic type. Payload header suppression, packing, and fragmentation, the convergence sublayers and MAC.

  13. Frequency • Originally Working 10 to 66ghz FDD or TDD. • Now supporting 2 to 11ghz with 802.11a. OFDMA with TDMA access.

  14. NLOS • Wifi only work on Line of Sight Areas • NON Line Of Sight capability in 2-11ghz. OFDMA.

  15. Usage Areas • Broadband Internet Access • Voip , IPTV services • Cellular Phones

  16. Content • History Of Wireless • Wimax • Advantages Over Wifi • MAC Structure • Usage Areas • Competitors • Conclusion

  17. Competitors • UMTS • HIPERMAN

  18. Content • History Of Wireless • Wimax • Advantages Over Wifi • MAC Structure • Usage Areas • Competitors • Conclusion

  19. Conclusion • Framework for the evolution of wireless broadband • Everything will be coordinated with Wimax
