7. WORKING OF WIMAX

8. WIMAX ACCESSING DEVICES

9. 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

10. Applications
• Public safety
• Campus connectivity
• Banking networks
• Educational networks e.t.c,

11. 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

12. DISADVANTAGES
The main disadvantage is
• Limitations on battery power
• Poor power efficiency

13. 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.
