IEEE 802. 11ac: High-impact Technology - What You Need to Know : Definitions, Adoptions, Impact, Benefits, Maturity, Vendors

IEEE 802.11ac is a wireless standard of 802.11 currently under development which will provide high throughput Wireless Local Area Networks (WLAN) below 6 GHz (i.e., what is commonly known as the 5 GHz band). Theoretically, this specification will enable multi-station WLAN throughput of at least 1 gigabit per second (1 Gbit/s) and a maximum single link throughput of at least 500 megabit per second (500 Mbit/s). This is accomplished by extending the air interface concepts embraced by 802.11n: wider RF bandwidth (up to 160 MHz), more MIMO spatial streams (up to 8), multi-user MIMO, and high-density modulation (up to 256 QAM). On January 20, 2011, the Initial Technical Specification Draft 0.1 was confirmed by IEEE 802.11 TGac. Standard finalization is anticipated in late 2012, with final 802.11 Working Group approval in late 2013. According to a study, devices with the 802.11ac specification are expected to become common by 2015 with an estimated 1 billion spread around the world.
