2. Think about how you access the
Internet today??????
Different options
o Broadband access
o Wi-Fi access
o Dial – up access

3. •
•
•
•
•
High Speed
Wireless
Less expensive
Broad coverage
Remote Access

4. WiMAX
Worldwide Interoperability for Microwave
Access (or) IEEE 802.16

6. WiMAX Tower
WiMAX Receiver

7. • LOS – Line Of Sight
• NLOS – Non Line Of Sight

9. • 70 Megabits per second.
• 30 miles (50 km) with wireless access.
• The increased range is due to the frequencies
used and the power of the transmitter.
• The biggest difference isn't speed;
it's distance

11. • Range – 30 mile (50 km)
• Speed – 70 Megabits per second
• Frequency band – 2 to 11 GHz and 10
to 66 GHz

12. • Support for privacy
• Device / user authentication
• Support for fast handover

13. •
•
•
•
•
Long range
Low Cost
Security
Higher Bandwidth
Coverage

14. • Power sensitive technology
• Bad Weather conditions interrupt the
signals
• Very power consuming
• More users – Lower speed
• Other Wireless equipments may cause
interference

15. •
•
•
•
•
•
Video Streaming.
VoIP , Video on Demand.
Video Conference.
Surveillance and monitoring.
E – learning.
Other general apps….

18. WiMAX
• Substitutes 3G & promising 4G.
• Very High speed Wireless in presence of
mobility.

19. • Consider a scenario where a WiMAX enabled
computer is 10 miles away from WiMAX base
station.
• A special encryption code is given to computer
to gain access to base station
• The base station would beam data from the
Internet required for computer (at speeds
potentially higher than today's cable modems)

20. • The user would pay the provider monthly fee for using the
service. The cost for this service could be much lower than
current high-speed Internet-subscription fees because the
provider never had to run cables
• The WiMAX protocol is designed to accommodate
several different methods of data transmission, one of
which is Voice Over Internet Protocol (VoIP)
• If WiMAX-compatible computers become very common,
the use of VoIP could increase dramatically. Almost
anyone with a laptop could make VoIP calls

21. • Wireless industry is revolutionizing our dynamic
world.
• WiMAX could bring broadband access into the
homes and business.
• Portable internet - a reality
“ALWAYS BEST CONNECTED”
