3. INTRODUCTION

• WiMAX (Worldwide Interoperability for Microwave Access) is a telecommunications protocol that provides fixed and fully mobile internet...

4. Principles of WiMAX

Idea to built MAN networkwith high bit rate and global range wideband access to theinternet

Worldwide interoperability for Microwave Access.

Founded in 2004 manged by wiMax forum

5. Features of WiMAX

Wimax support multipath

Wimax broadband access

Wimax offer high speed data rate

Wimax offer modulation and error correction

Wimax support reliability of data

Wimax support TDD and FDD

6. Working of WiMAX 7. Technologies used in WiMAX

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.

8. Applications

1.Residential or Home and Broadband Internet Access:

2.Medium and small size business:

3.Backhaul networks for cellular base stations:

4.WiFi Hotspots.

9. Advantages

1.Provides mobility to user with access to the Internet.

2. Convenient to user because of the ubiquitous connection.

3. High speed radio wave data transmission (up to 10Mb).

4. Does not require telephone line.

5. Designed with better quality of service (QoS)

6. Non-line of sight connection.

7. Provides wide area connectivity up to 50km radius from transmission tower.

10. Disadvantages

1. New technology which is still unstable, frequent disconnections.

2. Many interference disruption/slows down connection (weather, cordless phone, microwave oven)

3. Connection weakens when distance increases, away from transmission tower.

4. Wireless technology more prone to hackers.

11. Future Scope

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.

This technology would give rise to a broad consumer market for wireless digital devices.

WiMAX is a technology which considered as the first step toward 4G.

12. Conclusion

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.

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.
