“Wi-Fi Alliance® is expanding Wi-Fi CERTIFIED™ ac to include new features that provide a higher-performance mobility experience. New “wave 2” features enable Wi-Fi® to more efficiently handle high-bandwidth applications from an increasing number of smartphones, tablets, TVs, and other consumer electronics devices simultaneously connected to Wi-Fi networks. Wi-Fi CERTIFIED ac delivers greater network capacity and multi-gigabit speeds to benefit consumers, service providers, and enterprises. Multi-user Multiple Input Multiple Output (MU-MIMO) is among the most anticipated new features of Wi-Fi CERTIFIED ac, allowing more devices to operate simultaneously on the same network without sacrificing speed or performance. In addition to increased network capacity enabled with MU-MIMO, devices supporting the full set of new features are capable of achieving up to three times the speed of devices supporting only original Wi-Fi CERTIFIED ac features. “
