#1038 WiFi wave2 gets multi-gigabit, multi-user boost with upgrades to 802.11ac
The Wi-Fi Alliance industry group is now certifying products that can deliver multi-gigabit speeds and improve coverage in dense networks by delivering data to multiple devices simultaneously.

The new certification program, announced today, focuses on the so-called "Wave 2" features of the 802.11ac specification. 802.11ac is a few years old, but it includes several important features that were not available at launch. One such feature is MU-MIMO (multi-user, multiple-input, and multiple-output), which we wrote a feature on in May 2014. MU-MIMO is powered by multi-user beamforming technology that lets wireless access points send data streams to at least three users simultaneously. Without MU-MIMO, routers stream to just one device at a time but switch between them very fast so that users don't notice a slowdown except when lots of devices are on the network.
