About IEEE 802.11

IEEE 802.11 is a family of specifications for wireless local area network (WLAN) communications in the bands from 2.4, up to 5 GHz. The 802.11 standard is a set of evolving specifications. In 1997 the IEEE published the document IEEE Std. 802.11-1997, as the first wireless LAN standard. In the following years many enhancement versions of 802.11 were approved to cope with the WLAN fast growing market. In 2007, the IEEE 802.11 Task Group created the IEEE 802.11-2007, a single specification that merged 8 amendments (802.11a, b, d, e, g, h, i, j) with the legacy standard. IEEE 802.11n is a recent amendment which builds on the previous specifications by adding multiple-input multiple-output (MIMO) antennas, together with many other enhancement features. The IEEE has officially approved the amendment in October 2009 as IEEE Std. 802.11n-2009
