True 4G Standard WiMax-2 Approved by IEEE
WiMax-2, which also goes by WirelessMAN-Advanced and 802.16m, has been approved by the IEEE. Unlike LTE and HSPA+, it's acknowledged by the ITU as real 4G.WiMax is getting a boost. Global standards body Institute of Electrical and Electronics Engineers has approved IEEE 802.16m, the wireless standard for the next generation of WiMax, known as WiMax-2, or WirelessMAN-Advanced. The standard potentially could offer downstream speeds of more than 300M bps. The standard was the work of "hundreds of creative and diligent professionals from over 20 countries during the last four years," Roger Marks, chairman of the IEEE 802.16 Working Group, said in a March 31 statement. "Our organization was able to efficiently harmonize these innovative technologies into a clear set of specifications guiding the future development of the mobile broadband marketplace."
"ICTs [information and communication technologies] and broadband networks have become vital national infrastructure - similar to transport, energy and water networks - but with an impact that promises to be even more powerful and far-reaching," ITU Secretary-General Hamadoun Tour??Â« said in a statement announcing its findings in October 2010. "These key enhancements in wireless broadband can drive social and economic development, and accelerate progress towards achieving the United Nations' Millennium Development Goals." The speedy 802.16m, the IEEE has announced, incorporates multi-user MIMO (multiple input, multiple output), multicarrier operation and cooperative communications, and supports femto-cells, self-organizing networks and relays. It's going to be adopted, the IEEE added, by "major worldwide governmental and industrial organizations," such as the Association of Radio Industries and Businesses, and the WiMax Forum. Sprint, which is the majority owner of Clearwire, has previously expressed interested in WiMax-2. But with Clearwire currently struggling to find funding to keep its WiMax buildout proceeding, and Sprint facing the stress of being dwarfed by AT&T's proposed purchase of T-Mobile, it's unlikely to pursue the technology anytime soon.
