2X2:2 MU-MIMO
2X2:2 MU-MIMO WiFi means an AP allows two transceivers and two receivers to communicate
concurrently with multiple WiFi clients, dividing up the bandwidth evenly. In 2X2:2, the first and second
number (n X n)) show the number of transmit and receive antennas respectively. The third number (: n)
means the number of data spatial streams, indicating the number of independent data signals that can
be sent simultaneously from a single transmit antenna. For example, in Figure 12, when two WiFi devices
are connected to an AP, the AP can communicate with two devices (Client C1 and C2) simultaneously.

4X4:4 MU-MIMO
4X4:4 MU-MIMO WiFi means an AP allows four transceivers and four receivers to communicate
concurrently with multiple WiFi clients, dividing up the bandwidth evenly. For example, in Figure 13,
when four WiFi devices are connected to an AP, the AP can communicate with four devices (Client C1,
C2, C3 and C4) simultaneously.
