The latest IEEE Wi-Fi standard, which was designed to improve wireless services in the enterprise as well as support multiple streams of HD video in the home. Also known as "Gigabit Wi-Fi" and "5G Wi-Fi," products became available in 2012 before the standard was approved in early 2014.

Operating only in the 5 GHz band, devices are backward compatible with 802.11n, which is expected to co-exist with 802.11ac until the 2020s. An 802.11ac access point employs beamforming, which uses feedback to aim the transmission more directly to the receiving device. The second generation Wave 2 supports multiuser MIMO (MU-MIMO) with a total of eight simultaneous streams and up to four per client. See 2.5/5G Ethernet, 802.11n, 802.11ad, OFDM and QAM.
