This is going to get a little nerdy, but bear with us. MU-MIMO (pronounced em-you my-moh, and short for multi-user, multi-input and multi-output) is a revolutionary new way for Wi-Fi networks to operate. With traditional Wi-Fi, devices are served one at a time, creating a drop in throughput and capacity. This situation is made worse when multiple devices begin streaming high-resolution video. MU-MIMO solves this problem by transmitting simultaneously to several devices, significantly speeding up transmissions and making the most of your high-speed Wi-Fi network.
