  • WiMAX Presented By, Vidhya.R & Prema.S Pre – final year Info tech. VIVEKANANDHA ENGINEERING COLLEGE FOR WOMEN,SANKARI.
  • Think about how you access the Internet today?????? Different options o Broadband access o Wi-Fi access o Dial – up access
  • • • • • • High Speed Wireless Less expensive Broad coverage Remote Access
  • WiMAX Worldwide Interoperability for Microwave Access (or) IEEE 802.16
  • WiMAX Tower WiMAX Receiver
  • • LOS – Line Of Sight • NLOS – Non Line Of Sight
  • • 70 Megabits per second. • 30 miles (50 km) with wireless access. • The increased range is due to the frequencies used and the power of the transmitter. • The biggest difference isn't speed; it's distance
  • • Range – 30 mile (50 km) • Speed – 70 Megabits per second • Frequency band – 2 to 11 GHz and 10 to 66 GHz
  • • Support for privacy • Device / user authentication • Support for fast handover
  • • • • • • Long range Low Cost Security Higher Bandwidth Coverage
  • • Power sensitive technology • Bad Weather conditions interrupt the signals • Very power consuming • More users – Lower speed • Other Wireless equipments may cause interference
  • • • • • • • Video Streaming. VoIP , Video on Demand. Video Conference. Surveillance and monitoring. E – learning. Other general apps….
  • WiMAX • Substitutes 3G & promising 4G. • Very High speed Wireless in presence of mobility.
  • • Consider a scenario where a WiMAX enabled computer is 10 miles away from WiMAX base station. • A special encryption code is given to computer to gain access to base station • The base station would beam data from the Internet required for computer (at speeds potentially higher than today's cable modems)
  • • The user would pay the provider monthly fee for using the service. The cost for this service could be much lower than current high-speed Internet-subscription fees because the provider never had to run cables • The WiMAX protocol is designed to accommodate several different methods of data transmission, one of which is Voice Over Internet Protocol (VoIP) • If WiMAX-compatible computers become very common, the use of VoIP could increase dramatically. Almost anyone with a laptop could make VoIP calls
  • • Wireless industry is revolutionizing our dynamic world. • WiMAX could bring broadband access into the homes and business. • Portable internet - a reality “ALWAYS BEST CONNECTED”
