Broadband wireless access (BWA) has become the best way
to meet escalating business demand for rapid Internet
connection and integrated data, voice and video services. BWA
can extend fiber optic networks and provide more capacity than
cable networks or digital subscriber lines (DSL).
The Institute of Electrical and Electronics Engineers
Standards Association (IEEE-SA) sought to make BWA more
widely available by developing IEEE Standard 802.16, which
specifies the WirelessMAN Air Interface for wireless
metropolitan area networks.
為了促進寬帶無線設備的標準化，推動其市場發展，由Intel等眾多
頂級通信部件、設備公司在2003 年4 月組成了非營利性機構
WiMAX，致力于推動802.16無線寬帶設備進入市場，加速最后一公
里的寬帶部署。
WiMAX = “Worldwide Interoperability for Microwave Access”
WiMAX 是基于(IEEE 802.16) 技術標準的最后一公里寬帶無線
