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
FUNDAMENTAL TECHNOLOGIES IN WIMAX
• Adaptive modulation
• Orthogonal Frequency Division Multiplexing
• FDM and TDM
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
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
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.
