latest 4G WiMax Technology

The Institute of Electrical and Electronics Engineers has permitted the IEEE 802.16m, the standard for the next generation of WiMax, which can provide downstream speeds of more than 300m bps (bits per second).
IEEE 802.16m, also known as WirelessMAN-Advanced or WiMax-2, was developed as the next step after 802.16e, the first global standard for mobile WiMax. The new standard is more than four years in the making, according to the IEEE, but it comes as WiMax exceed appear around the mobile world. A significant majority of these carriers make in building the so-called 4G (fourth generation) networks chose LTE (Long Term Evolution) as a basis of characteristics of stock in WiMax, but comes in a variety of body standards. The CEATAC fair in Tokyo last year, Samsung suggests a pre-standard 802.16m network that reaches a speed of 330m bps. The standard design speed of 100 m bps to end users. It can use several techniques to improve the performance of the current WiMax technology to take, including MIMO (multiple in, multiple out) technology to send over a stream of data. It can also be used on a small base stations called femtocells and self-organizing network, according to the IEEE. The new standard is backward compatible with current WiMax.
Last year, 802.16m achieved the distinction of becoming recognized as a true 4G technology by the ITU (International Telecommunication Union). It is situated next to the LTE-Advanced, a future version of LTE that likewise is not commercially available, a definition that ran into the current widespread use of WiMax and LTE 4G described. But the ITU later relaxed its definition of the term so much that they even opened the door for carriers like T-Mobile USA described variants of 3G technology and 4G.
WiMax is used for stationary or nomadic wireless broadband in many parts of the world. The 802.16e mobile WiMax standard was approved in the middle of the decade accounted for LTE, and run the first national network in the U.S. with a technology of the next generation. But a large equipment and device ecosystem that is now growing about LTE, and even clear, the world's largest mobile WiMax service provider, is testing the technology.
Sprint Nextel, majority owner of Clear, indicated last year it was interested in 802.16m, which is said to offer 128M bps bps in the 360m. Clear but strapped for cash to further expand its network, many observers raised questions about the future of technology required by both companies.
