From mid-2013, the alliance started certifying Wave 1 802.11 ac products ships by manufacturers, based on the IEEE 802.11ac Draft 3.0 (the IEEE standard was not finalized until later that year). ![]() ![]() 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 eight), downlink multi-user MIMO (up to four clients), and high-density modulation (up to 256-QAM).Wi-Fi Alliance separated the introduction of ac wireless products into two phases ('wave'), named 'Wave 1' and 'Wave 2'. The standard has been retroactively labelled as Wi-Fi 5 by Wi-Fi Alliance.The specification has multi-station throughput of at least 1 gigabit per second and single-link throughput of at least 500 megabits per second (500 Mbit/s). The standard was developed in the IEEE Standards Association from 2008 (PAR approved ) through 2013 and published in December 2013 (ANSI approved ). From Wikipedia, the free encyclopedia Jump to navigation Jump to search IEEE 802.11ac is a wireless networking standard in the 802.11 set of protocols (which is part of the Wi-Fi networking family), providing high-throughput wireless local area networks (WLANs) on the 5 GHz band.
