What is multi-user communication?

Multi-user MIMO (MU-MIMO) is a wireless communication technology that uses multiple antennas to improve communication by creating multiple connections to the same device at the same time. MIMO is an acronym which stands for multiple-input and multiple-output.

What is the difference between MIMO and MU-MIMO?

The biggest difference between MIMO and MU-MIMO is that MU-MIMO can communicate with multiple users meanwhile instead of only one user like MIMO.

How does MIMO work?

An acronym for Multiple-In, Multiple-Out, MIMO communication sends the same data as several signals simultaneously through multiple antennas, while still utilizing a single radio channel. This is a form of antenna diversity, which uses multiple antennas to improve signal quality and strength of an RF link.

What is MU-MIMO in wireless communication?

MU-MIMO allows an access point to communicate with multiple devices simultaneously. It is part of the Wi-Fi 5 (802.11ac) Wave 2 standard. With MU-MIMO, an access point or a wireless router can communicate with multiple network clients at the same time – thus increasing the speed of the data transfer without congestion.
