IEEE 802.11ac is a wireless computer networking standard of 802.11, developed in the IEEE Standards Association process, providing high-throughput wireless local area networks on the 5 GHz band.
This specification has expected multi-station WLAN throughput of at least 1 gigabit per second and a single link throughput of at least 500 megabits 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).
