  • 1. WIMAX BY MUHAMMAD FAHD UN NABI KHAN fahdunnabi@hotmail.com X-O USMAN PUBLIC SCHOOL
  • 2. What is WIMAX? WIMAX stands for Worldwide Interoperability for Microwave Access WiMAX refers to broadband wireless networks that are based on the IEEE 802.16 standard, which ensures compatibility and interoperability between broadband wireless access equipment WiMAX, which will have a range of up to 31 miles, is primarily aimed at making broadband network access widely available without the expense of stringing wires (as in cable-access broadband) or the distance limitations of Digital Subscriber Line.
  • 3. THINK OF INTERNET There are three possible ways to access internet.  Broadband access Uses DSL or cable modem at home and T1 or T3 line at office  WIFI Uses WIFI routers at home and hotspots on the road  Dial Up Connection
  • 4. NEW TECHNOLOGY Broadband access is too expensive and WiFi coverage is very sparse. The new technology promises  High speed of broadband service  Wireless rather than wired access  Broad Coverage
  • 5. FEATURES OF WIMAX Scalability Quality of Service Range Coverage
  • 6. A WIMAX system consists of:1) A WiMAX tower, similar in concept to a cell-phone tower - A single WiMAX tower can provide coverage to a very large area as big as 3,000 square miles (~8,000 square km).2) A WiMAX receiver - The receiver and antenna could be a small box or Personal Computer Memory card, or they could be built into a laptop the way WiFi access is today
  • 7. WIMAX TOWER WIMAX RECEIVER
  • 8. HOW WIMAX works?
  • 9. WIMAX CHIPSWiMAX Mini-PCI Reference Design Intel’s first WIMAX chip
  • 10. RANGE Optimized for up to 50 Km Designed to handle many users spread out over kilometres Designed to tolerate greater multi- path delay spread (signal reflections) up to 10.0μ seconds
  • 11. BENEFITS OF WIMAX Speed  Faster than broadband service Wireless  Not having to lay cables reduces cost  Easier to extend to suburban and rural areas Broad Coverage  Much wider coverage than WiFi hotspots
  • 12. Benefits to Customers Range of technology and service level choices from both fixed and wireless broadband operators DSL-like services at DSL prices but with portability Rapidly declining fixed broadband prices No more DSL “installation” fees from incumbent
  • 13. USES OF WIMAX
  • 14. More ……
  • 15. FUTURE WiMax will be deployed in three stages  In the first phase WiMaX technology (based on IEEE 802.16-2004) provides fixed wireless connections  In the second phase WiMaX will be available as a cheap and self-installing Subscriber Terminal (ST), linked to PC and to antenna  The third phase enables portability, thus WiMAX (based on IEEE 802.16e) will be integrated into commercial laptops
