The number of connected devices in the average home or office is also increasing. At the same time more and more devices are being used to support more bandwidth-intensive activities. As a result, the connected devices experience low Wi-Fi performance.
Reduced Wi-Fi performance
Transfer One By One
For purpose of enhancing Wi-Fi performance, the mode SU-MIMO need to be changed, which means Single-User MIMO. Because most Wi-Fi routers with Single-User MIMO serve only single user at a time and our routers generally provide 3 data streams or more, but most of users actually received only 1~2 data streams, such as smart phone, tablet, notebook, or even your apple TV, that is to say, users cannot make the best of routers capacity. For example, a 3x3 11ac Wi-Fi router with Single-User MIMO can support a peak Wi-Fi speed of 1.3Gbps. But a smartphone or tablet with one antenna only supports a peak rate of only 433 Mbps, leaving 867 Mbps capacity.
Transfer at the same time
The traditional Wi-Fi routers with Single-User MIMO serve only one user at a time while other users that rely on that connection are forced to wait, which diminishes performance and overall capacity. This effect is even stronger when more than one user attempts to access multi-media content, such as HD video.
MU-MIMO solves this problem by creating 3 simultaneous connections to serve several users with 3 data streams at the same time. With technological development MU-MIMO can provide more spatial streams and serve more users simultaneously.
Since a MU-MIMO network does not require its client devices to time-share connections with other clients on the network, each device experiences less wait time, enabling a more responsive network and client devices.
Router with MU-MIMO unlocks previously unused capacity by serving 3 users at a time.
For Multi-User clients, the network has more free time or capacity to serve legacy clients, which means even legacy clients benefit with MU-MIMO.
