WiMAX

  1. 1. WiMAX (Worldwide Interoperability for Microwave Access) P. Kiran Kumar Reddy (08Q61A0586)
  2. 2. Contents <ul><li>Introduction </li></ul><ul><li>Principles </li></ul><ul><li>Features </li></ul><ul><li>Working </li></ul><ul><li>Applications </li></ul><ul><li>Advantages and Disadvantages </li></ul><ul><li>Future Scope </li></ul><ul><li>Conclusion </li></ul>
  3. 3. INTRODUCTION <ul><ul><li>WiMAX (Worldwide Interoperability for Microwave Access) is a telecommunications protocol that provides fixed and fully mobile internet... </li></ul></ul>
  4. 4. Principles of WiMAX <ul><li>Idea to built MAN network with high bit rate and global range wideband access to the internet </li></ul><ul><li>Worldwide interoperability for Microwave Access. </li></ul><ul><li>Founded in 2004 manged by wiMax forum </li></ul>
  5. 5. Features of WiMAX <ul><li>Wimax support multipath </li></ul><ul><li>Wimax broadband access </li></ul><ul><li>Wimax offer high speed data rate </li></ul><ul><li>Wimax offer modulation and error correction </li></ul><ul><li>Wimax support reliability of data </li></ul><ul><li>Wimax support TDD and FDD </li></ul>
  6. 6. Working of WiMAX
  7. 7. Technologies used in WiMAX <ul><li>Within the marketplace, WiMAX 's main competition came from existing, widely deployed wireless systems such as  Universal Mobile Telecommunications System  (UMTS),  CDMA2000 , existing Wi-Fi and mesh networking. </li></ul>
  8. 8. Applications <ul><li>1. Residential or Home and Broadband Internet Access: </li></ul><ul><li>2. Medium and small size business: </li></ul><ul><li>3. Backhaul networks for cellular base stations: </li></ul><ul><li>4. WiFi Hotspots. </li></ul>
  9. 9. Advantages <ul><li>1. Provides mobility to user with access to the Internet. </li></ul><ul><li>2. Convenient to user because of the ubiquitous connection. </li></ul><ul><li>3. High speed radio wave data transmission (up to 10Mb). </li></ul><ul><li>4. Does not require telephone line. </li></ul><ul><li>5. Designed with better quality of service (QoS) </li></ul><ul><li>6. Non-line of sight connection. </li></ul><ul><li>7. Provides wide area connectivity up to 50km radius from transmission tower. </li></ul>
  10. 10. Disadvantages <ul><li>1. New technology which is still unstable, frequent disconnections. </li></ul><ul><li>2. Many interference disruption/slows down connection (weather, cordless phone, microwave oven) </li></ul><ul><li>3. Connection weakens when distance increases, away from transmission tower. </li></ul><ul><li>4. Wireless technology more prone to hackers. </li></ul>
  11. 11. Future Scope <ul><li>Future Scope is considered to be a next generation technology because this technology is aimed at replacing most of the present wireless technologies like wifi, Bluetooth, microwave and mobile phone technologies. </li></ul><ul><li>This technology would give rise to a broad consumer market for wireless digital devices. </li></ul><ul><li>WiMAX is a technology which considered as the first step toward 4G. </li></ul>
  12. 12. Conclusion <ul><li>WiMAX is a technology in its infancy. It supplies solutions for backhaul connectivity for existing wireless hotspots and also offers end-user access in the unlicensed portion of the wireless spectrum. Local regulations may prevent WiMAX from reaching its full potential in the unlicensed spectrum.  </li></ul><ul><li>Its LOS soluions lie in the licenced portion of the spectrum and these will be able to supply remote areas with Internet connectivity in a cost-effective manner providing that the licensing authorities do not overcharge providers for the licences. </li></ul>
