Worldwide Interoperability for Microwave Access (WiMAX) is a wireless communications technology. As the global economy continues to expand, so does the demand for information. This information needs to be plentiful, diversified, instant, sprinkled and mobile, all at the same time. These mounting demands have proven difficult for existing network capacity, coverage and range also. And this reduces an organizations ability to evolve with changing business and workforce needs. Wireless networks are best suited to meet these challenges because they are resilient, scalable, mobile and cost-effective. It facilitates the network with high-speed, high quality data, voice and video communication, even when users are on the move. The rapid growth of WIFI in the home, enterprise and public hotspot market has given users and service providers alike a new glimpse into what wireless connectivity can deliver, through a single interface, in multiple locations. WIFI realizes the vision of broadband connectivity within the LAN (Local Area Network) and has easy way for new wireless technologies that can deliver the same experience in the MAN (Metropolitan Area Network) and in the WAN (Wide Area Network).

Excerpt from the Book
WIMAX VS WIFI
WiMAX operates on the identical wide-ranging ideology as WiFi. It sends data commencing single central processing unit to an additional via broadcasting signals. A central processing unit prepared with WiMAX would be given data beginning the WiMAX transmitting position, in all probability using encrypted information keys to avoid unconstitutional users from larceny admittance. [21 - 23] The greatest WiFi association can broadcast up to 54 megabits for each subsequent underneath the majority constructive location. WiMAX be supposed to be intelligent to switch up to 70 megabits for each following. Level some time ago that 70 megabits is separated up between more than a few dozen businesses or a small amount of hundred home users, it will make available at smallest amount the correspondent of cable modem transport charge to everyone customer.
The prevalent difference isn't momentum it's remoteness. WiMAX outdistances WiFi by means of miles. WiFi's assortment is in relation to 100 feet (30 m). WiMAX will bedspread a radius of 30 miles (50 km) through wireless right to use. The augmented assortment is outstanding to the frequencies second-hand and the influence of the spreader. Of track, at that detachment, atmosphere, weather conditions and bulky buildings will take action to diminish the maximum assortment in a quantity of state of affairs, but the budding is in attendance to envelop enormous tracts of territory [21 - 23]
