• Introduction • Architecture of Wimax• Fundamental technologies in Wimax• Working of Wimax• Features• Applications • Advantages• Disadvantages• CONCLUSION

INTRODUCTION

• WIMAX=WORLD WIDE INTEROPERABILITY FOR MICROWAVE ACCESS • IEEE 802.16 STANDARD• WIRELESS MAN

Requirements

There are two basics things required to access wimax:

• WIMAX TOWER• WIMAX SUBSCRIBER DEVICE or RECEIVER

ARCHITECTURE OF WIMAX

• BASE STATION • SUBSCRIBER STATION

FUNDAMENTAL TECHNOLOGIES IN WIMAX

• Adaptive modulation

• Orthogonal Frequency Division Multiplexing

• FDM and TDM

WORKING OF WIMAX

WIMAX ACCESSING DEVICES

FEATURES

• Advanced Security• Licensed Spectrum• Allows Non Line of sight operation• Frequency band 2 to 11ghz• Wimax offers excellent capabilities• Robust• Improvement on the modulation schemes

Applications

• Public safety

• Campus connectivity

• Banking networks

• Educational networks e.t.c,

ADVANTAGES

• Provides symmetrical bandwidth over many kilometers

• Its range is up to 50 kms compare to wifi-91mts

• High speed up to 70 mbps,• Greater number of users• Low cost

DISADVANTAGES

The main disadvantage is

• Limitations on battery power • Poor power efficiency

CONCLUSION

• which plays a vital role in modern world .• this wimax Range is increasing and price

decreasing by using various modulation technologies

• this field has relatively more advantages than disadvantages and hence is very useful in varied branches.
