The IEEE Standards Association (IEEE-SA) 
Standards Board has approved IEEE 802.16m, which incorporates advanced communications technologies such as multi-user MIMO, multicarrier operation, and cooperative communications. It supports femto-cells, self-organizing networks, and relays. Major worldwide governmental and industrial organizations, including ARIB, TTA, and the WiMAX Forum, are adopting this standard.
IEEE 802.16m provides the performance improvements necessary to support future advanced services and applications for next generation broadband mobile communications. In October 2010, ITU-R agreed to incorporate this technology into its IMT-Advanced Recommendation specifying systems that support low to high mobility applications, a wide range of data rates in multiple user environments, high-quality multimedia applications, and significant improvements in performance and quality of service.http://www.wirelessman.org/http://www.ieee.org
