===Standards===
# [http://standards.ieee.org/getieee802/download/802.16.2-2004.pdf IEEE 802.16-2004 (802.16d)] addresses only fixed systems
# [http://standards.ieee.org/getieee802/download/802.16e-2005.pdf IEEE Std 802.16e-2005], also called mobile WiMaxWiMAX
#* 802.16e also bring Multiple Antenna Support through Multiple-input multiple-output communications. This brings potential benefits in terms of coverage, self installation, power consumption, frequency re-use and bandwidth efficiency. 802.16e also adds a capability for full mobility support.
# WiMAX II, 802.16m will be proposed for IMT-Advanced 4G (future development)

'''Market research data:'''
* Worldwide WiMax WiMAX equipment revenues are forecast to reach $3.26 billion in 2009
* Worldwide outdoor wireless mesh access node sales are forecast to reach $1.17 billion in 2009
* Samsung leads overall WiMax WiMAX equipment revenue share in 3Q06, ahead of Alvarion, Airspan, and Aperto Networks
* Strix Systems leads overall outdoor mesh revenue market share in 3Q06, just ahead of Tropos Networks and BelAir Networks
* 35% of WiMax WiMAX equipment sales come from Asia Pacific, 30% from EMEA, 20% from North America, and 14% from CALA
* 49% of wireless mesh access node sales come from North America, 25% from EMEA, 18% from Asia Pacific, and 8% from CALA
* 802.16 standards The first 802.16 standard was approved in December 2001. It delivered a standard for point to multipoint Broadband Wireless transmission in the 10-66 GHz band, with only a Line of Sight (LOS) capability. It uses a single carrier (SC) physical (PHY) standard. [http://www.bbwexchange.com/pubs/2006/12/05/page1421-371393.asp Source]
