  1. 2. INTERNET INTERNET BROADBAND ACCESS Wi-Fi ACCESS DIAL-UP ACCESS
  2. 3. <ul><li>Broadband –through DSL or cable modem. </li></ul><ul><li>Wi-Fi – through Wi-Fi router. </li></ul><ul><li>Dial-up – through telephone network.Speed is a problem </li></ul>
  3. 4. What if there were a new technology that solved all of these problems? <ul><li>High speed </li></ul><ul><li>Wireless </li></ul><ul><li>Coverage </li></ul><ul><li>and that is ….. </li></ul>
  4. 6. WiMAX <ul><li>World wide Interoperability for Microwave Access. </li></ul><ul><li>Aimed at providing wireless broadband connection over long distances. </li></ul><ul><li>Coverage in square miles. </li></ul>
  5. 7. <ul><li>It is based on IEEE 802.16 standard. </li></ul><ul><li>It is also called Wireless MAN. </li></ul><ul><li>Providing a wireless alternative to cable and DSL broadband access. </li></ul><ul><li>Providing high speed mobile data and telecommunication services. </li></ul>
  6. 8. COMPONENTS <ul><li>Base station. </li></ul><ul><li>WiMAX hub. </li></ul><ul><li>WiMAX enabled devices. </li></ul>
  7. 10. WiMAX <ul><li>Neither wimax of Wi-Fi is a technology. </li></ul><ul><li>A certification mark or stamp of approval. </li></ul><ul><li>The hardware should follow the specificction. </li></ul><ul><li>Wimax enhances Wi-Fi </li></ul>
  8. 11. IEEE 802.16 specification <ul><li>Range - 30-mile (50-km) radius from base station </li></ul><ul><li>Speed - 70 megabits per second </li></ul><ul><li>Line-of-sight not needed between user and base station </li></ul><ul><li>Frequency bands - 2 to 11 GHz and 10 to 66 GHz </li></ul><ul><li>Defines both the MAC and PHY layers and allows multiple PHY-layer specifications </li></ul>
  9. 12. WORKING <ul><li>With WiMAX we create ubiqutious access. </li></ul><ul><li>WiMAX would operate similar to Wi-Fi but at higher speed. </li></ul><ul><li>A typical WiMAX system consists of two parts. </li></ul><ul><li>1. WiMAX tower. </li></ul><ul><li>2. WiMAX receiver. </li></ul>
  10. 13. PARTS <ul><li>A WiMAX tower station can connect directly to the Internet using a high-bandwidth, wired connection. </li></ul><ul><li>It can also connect to another WiMAX tower using a line-of-sight, microwave link. </li></ul>
  11. 17. OPERATION <ul><li>WiMAX operates on the same general principles as Wi-Fi . </li></ul><ul><li>It sends data from one computer to another via radio signals. </li></ul>
  12. 19. dozens dozens thousands Number of users 20Kbps 11Mbps 70Mbps Data transfer rate ~10meters ~100meters ~31miles Range varies 2.4GHz 2-11GHz Frequency Band 802.15 (Bluetooth) 802.11 (WLAN) 802.16 (WiMAX) Parameters
  13. 20. <ul><li>WiMAX can provide two forms of wireless service </li></ul><ul><li>1..line of sight </li></ul><ul><li>2..nonline of sight </li></ul>
  14. 22. Wi-Fi v/s WiMAX <ul><li>Both are meant for wireless communication </li></ul><ul><li>WiMAX is a long range system </li></ul><ul><li>Wi-Fi is a short range system </li></ul><ul><li>Wi-Fi ->>>>CORDLESS PHONE </li></ul><ul><li>WiMAX->>>CELL PHONE </li></ul>
  15. 23. Range <ul><li>Wi Fi access will be limited to a 4-to-6 mile radius </li></ul><ul><li>WiMAX will be limited to 30-mile radius </li></ul><ul><li>A computer (either a desktop or a laptop) equipped with WiMAX would receive data from the WiMAX transmitting station. </li></ul>
  16. 28. FUTURE PERFECT <ul><li>Wireless technology that bring broadband to rural areas. </li></ul><ul><li>By 2010 industry analysts project the WiMAX market to be worth between $3 and $5 billion. </li></ul>
  17. 29. INDIA and WiMAX <ul><li>The demand for broadband connectivity . </li></ul><ul><li>Roling out copper to rural areas is close to impossible. </li></ul><ul><li>The government telecoms operator BSNL is also in the process of rolling out some WiMAX services. </li></ul><ul><li>WiMAX is the first truly broadband technology available to meet Indian market needs . </li></ul><ul><li>It is predicted that Indian WIMAX subscribers will around 13 million by 2012. </li></ul>
  18. 30. <ul><li>Dishnet wireless plans to spend US$50 million in india. </li></ul><ul><li>Reliance will also launch wimax in major cities. </li></ul>
  19. 31. WiMAX and BUSINESS
  20. 32. <ul><li>In this era businesses are expected to look to wireless technology to help them become more efficient. </li></ul><ul><li>Help businesspeople stay in business. </li></ul>
  21. 33. CONCLUSION <ul><li>Where ever you go i am there – WiMAX. </li></ul><ul><li>WiMAX is more like cable repalcement technology ,which competes with wired operators. </li></ul><ul><li>WiMAX is intended complement other wireless standards such as WLAN and cellular based data networks. Together these provide many options to meet customer needs and grow the overall opportunity for wireless systems. </li></ul>
