Agenda Introduction Technical Details Working of WiMax Comparison between technologies Advantages DisAdvantages Conclusion

Wi Max stands for Worldwide Interoperability for Microwave Access : 

Wi Max stands for Worldwide Interoperability for Microwave Access It is built on IEEE 802.16 standards It is a Wireless Technology that provides high throughput broadband connections over long distances.

Slide 4: 

It is a new standard developed by the IEEE that focuses on point to multipoint broadband wireless networks. Wi Max is both faster and has a longer range than Wi-Fi. It represents the next generation of wireless The First Wi Max Chip networking.

Slide 5: 

Technical Details:- Range 30 mile radius from base station. Speed 70 Megabits per second. Line of sight not needed between user and base station. Frequency bands- 2 to 11 GHz & 10 to 66 GHz

Slide 6: 

Working of Wi Max Wi Max operates similar to Wi-Fi but at high speeds, over long distances and for a greater number of users. A Wi Max consists of two parts A Wi Max tower, provides coverage to a very large area. Wi Max Transmitting Tower A Wi Max receiver and antenna could be a small box.

Slide 7: 

A Wi Max tower station can connect directly to the Internet using a high bandwidth wired connection. Wi Max can provide two forms of wireless service If there is a non-line-of-sight, a small antenna on your computer connects to the tower in the low frequency range of 2-11 GHz.

Slide 8: 

If there is a line-of-sight service, a fixed dish antenna points straight at the Wi Max tower from a rooftop or pole.

Slide 9: 

Comparison between Wi-Fi & WiMax: Wi-Fi 802.11 WiMax 802.16a Speed 6 - 54 Mbps 70 Mbps Coverage 30 m 50 km The biggest difference isn't speed, it's distance. Wi Max outdistances Wi-Fi by miles.

Advantages : 

Advantages 1) Single station can serve hundreds of users. 2) Much faster deployment of new users comparing to wired networks. 3) Speed of 10 Mbps at 10 kilometers within line-of-site.

Disadvantages : 

Disadvantages 1) Line of sight is needed for more distant connections. 2) Bad weather conditions such as rain could interrupt the signal.

Slide 12: 

CONCLUSION WiMax with all its challenges and opportunities is an unavoidable part of our future. It will lead great advances of commercial future. It can be said that WiMax is slowly but steadily ushering in the next generation.
