WiMAX is the latest technology in the field of wireless internet. In fact it is the only available technology which enables broadband in wireless internet. WiMAX is the acronym for worldwide interoperability for microwave access. To phrase in simple words, WiMAX enables the users to access high speed internet with extreme mobility. This technology has several benefits when compared with existing WiFi technology. WiMAX uses microwave as a medium for data transfer which means a tower similar to the cell phone tower is used. Due to the use of microwaves, for a range of thirty miles, the data transfer rate can be nearly 75 MBPS. This would enable high speed internet access to more than 1000 computers from a single tower. The major advantages of WiMAX are, rural areas will be able to access broadband internet very easily at a much cheaper rate, Setting up internet access for the whole city can be completed within a couple of days. This would mean that in the near future we would be able to access the internet as if we are using the cell phones. It is possible to get hooked to the net from almost anyplace in the world.
Network scale
The smallest-scale network possible is a personal area network (PAN). A PAN allows devices to communicate with each other over short distances. Bluetooth is the best example of a PAN. A local area network (LAN) can also be easily setup. A LAN allows devices to share information, but is limited to a fairly small central area, such as a company's headquarters, a coffee shop or your house. Many LANs use WiFi to connect the network wirelessly.
WiMAX is the wireless solution for the next step up in scale, the metropolitan area network (MAN). A MAN allows large areas to be connected, i.e. the size of a city can be connected very easily.
