  • 1. A Presentation On WIMAX
  • 2. ContentsIntroductionNew Technology WiMAXWorkingTypes of WiMAXAdvantages & DisadvantagesBroadband AccessFutureComparision of WiMAX & WIFIMobile WiMAX BroadbandConclusion
  • 3. INTRODUCTIONThere are basically three different options: BROADBAND ACCESS WIFI ACCESS DIAL-UP ACCESSThe main problems with broadband access are that it is pretty expensive & it doesn’t reach all areas.The main problem with WIFI is that hot spots are very small, so coverage is sparse.
  • 4. New Technology WiMAX This new Technology would provide:-That is less expensive than cableMuch easier to extend to rural areasBroad coverage like cell phone networks. WiMAX is a wireless digital communications system also known as IEEE 802.16.
  • 5. Working There are two parts:WiMAX TowerWiMAX ReceiverWiMAX stations connect directly to the internet with a wired connection.
  • 6. TYPES OF WIMAXFIXED WIMAX: Fixed WIMAX deployments do not cater for hand off between base stations, therefore the service provider cannot offer mobility.MOBILE WIMAX: Mobile WIMAX implementations can be used to deliver both fixed SAMSUNG MOBILE WIMAX DEVICES & mobile services.
  • 7. ADVANTAGESBandwidth FlexibilityPricing + Contract FlexibilityQuick InstallationInterpenetrationDISADVANTAGESWiMAX can operate at higher bitrates or over longer distances but not both.Omni directional antennas are used.
  • 8. BROADBAND ACCESSMany companies are closely examining WIMAX for “last-mile" connectivity at high data rates.The resulting competitions may bring lower pricing for both home & business customers, or bring broadband access to places where it has been economically unavailable.
  • 9. FUTUREAnywhere, Anytime, ConnectivityCost EffectiveHigh speed of Broadband service
  • 10. COMPARISON B/W WIMAX & WIFI WIMAX WiFiWiMAX is a long WiFi is shorter range system. range system.WiMAX provides WiFi is more services analogous to analogous to a cell phone. cordless phone.It uses a mechanism WiFi has based on setting up introduced a quality connections between of service the base station & mechanism similar user device. to fixed Ethernet, where packet can receive different priorities based on their tags.
  • 11. Mobile WIMAX Broadband
  • 12. Conclusion Within five years, we expect WiMAX to be the dominant technology for wireless networking. By that time it will be fully mobile, as well as providing low- cost, fixed broadband access that will open up regions where internet access has no far not been practical.
