4G Wireless Communication Using Mobile WIMAX Technology
WiMAX, meaning Worldwide Interoperability for Microwave Access, is a telecommunications technology that provides wireless transmission of data using a variety of transmission modes, from point-to-point links to portable internet access. The technology provides up to 75 Mbit/s symmetric broadband speed without the need for cables. The technology is based on the IEEE 802.16 standard (also called Broadband Wireless Access). The forum describes WiMAX as "A standards-based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DSL". Testing and certification to ensure interoperability is the main responsibility of the WiMAX forum.
