What is WiMAX?
WiMAX (Worldwide Interoperability for Microwave Access) is a telecommunications protocol that provides a fixed and a wireless Internet connection. It is also called as Broadband wireless Technology. It is the Wireless alternative to DSL cable network.
WiMAX can provide broadband wireless access (BWA) up to 50 km for fixed Network and 5 - 15 km for mobile Network.
It is the possible economic model for wireless carriers, where it is not possible to other Technology. That is it can be deployed in low cost compared to GSM and CDMA.
Why we need WiMAX?
LAN (Local Area Network) is possible in the Wireless Network through Wi-Fi technology. But it cannot be used in the Large Area Network such as MAN (Metropolitan Area Network).
But Wi-Fi is the best in the local area network.
To overcome the disadvantage of the Wi-Fi the developers are concentrated to develop new technology. At the same time 3G technologies emerged in the communication market.
Finally they developed the WiMAX technology based on the Scalable Orthogonal Frequency-division Multiple Access (SOFDMA). The SOFDMA offers the services very cheaper, very effective and easy implementation.
Now many devices are come with the WiMAX technology. Many mobile companies launch their Mobiles with this technology. Many ISP's also providing WiMAX USB internet Modem for Internet Connectivity.
It provides the wireless broadband service outside of the buildings and it offers the Quality of service.
