Data rates and speed Modulation and coding schemes Wave 2 also supports a higher number of connected devices. Wave 2 can therefore achieve 1 Gbit/s even if the real world throughput turns out to be only 50% of the theoretical rate. The maximum physical layer theoretical rate for Wave 1 is 1.3 Gbit/s, while Wave 2 can reach 2.34 Gbit/s. Wave 2, referring to products introduced in 2016, offers a higher throughput than legacy Wave 1 products, those introduced starting in 2013.

With the inclusion of USB 3.0 interface, 802.11ac access points and routers can use locally attached storage to provide various services that fully utilize their WLAN capacities, such as video streaming, FTP servers, and personal cloud services. The single-link and multi-station enhancements supported by 802.11ac enable several new WLAN usage scenarios, such as simultaneous streaming of HD video to multiple clients throughout the home, rapid synchronization and backup of large data files, wireless display, large campus/auditorium deployments, and manufacturing floor automation.

MAC modifications (mostly to support above changes).Beamforming with standardized sounding and feedback for compatibility between vendors (non-standard in 802.11n made it hard for beamforming to work effectively between different vendor products).Some vendors offer a non-standard 1024-QAM mode, providing 25% higher data rate compared to 256-QAM.256- QAM, rate 3/4 and 5/6, added as optional modes (vs.Downlink MU-MIMO (one transmitting device, multiple receiving devices) included as an optional mode.Space-division multiple access (SDMA): streams not separated by frequency, but instead resolved spatially, analogous to 11n-style MIMO.Multiple STAs, each with one or more antennas, transmit or receive independent data streams simultaneously.Downlink multi-user MIMO (MU-MIMO, allows up to four simultaneous downlink MU-MIMO clients).Support for up to eight spatial streams (vs.Optional 160В MHz and mandatory 80В MHz channel bandwidth for stations cf.New technologies introduced with 802.11ac include the following: 6.1 Commercial routers and access points.It meant Wave 2 products would have higher bandwidth and capacity than Wave 1 products. Subsequently in 2016, Wi-Fi Alliance introduced the Wave 2 certification, which includes additional features like MU-MIMO (down-link only), 160В MHz channel width support, support for more 5В GHz channels, and four spatial streams (with four antennas compared to three in Wave 1 and 802.11n, and eight in IEEE's 802.11ax specification). From mid-2013, the alliance started certifying Wave 1 802.11ac products shipped by manufacturers, based on the IEEE 802.11ac Draft 3.0 (the IEEE standard was not finalized until later that year). The Wi-Fi Alliance separated the introduction of ac wireless products into two phases ('waves'), named 'Wave 1' and 'Wave 2'. This is accomplished by extending the air-interface concepts embraced by 802.11n: wider RF bandwidth (up to 160В MHz), more MIMO spatial streams (up to eight), downlink multi-user MIMO (up to four clients), and high-density modulation (up to 256-QAM). The specification has multi-station throughput of at least 1.1 gigabit per second (1.1 Gbit/s) and single-link throughput of at least 500 megabits per second (0.5 Gbit/s). The standard has been retroactively labelled as Wi-Fi 5 by Wi-Fi Alliance. IEEE 802.11ac-2013 or 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 5В GHz band. Wireless networking standard in the 802.11 family
