Worldwide Interoperability for Microwave
Access (or) IEEE 802.16
• LOS – Line Of Sight
• NLOS – Non Line Of Sight
• 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;
• Range – 30 mile (50 km)
• Speed – 70 Megabits per second
• Frequency band – 2 to 11 GHz and 10
to 66 GHz
• Support for privacy
• Device / user authentication
• Support for fast handover

• Consider a scenario where a WiMAX enabled
computer is 10 miles away from WiMAX base
• 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)
• 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
• Wireless industry is revolutionizing our dynamic
• WiMAX could bring broadband access into the
homes and business.
• Portable internet - a reality
