Difference between single user MIMO vs Multiuser MIMO

single user MIMO

As shown in the figure 1, Access point compliant to IEEE 802.11ac standard transmits multiple streams using multiple antennas and all the streams are directed to single device. This is referred as Single user MIMO.





Multi user MIMO

As shown in the figure 2, Access point compliant to IEEE 802.11ac standard transmits multiple streams using multiple antennas. As shown two streams are directed to one device(nokia mobile) and other streams one to one device(tablet) and the other one to another device(laptop).This is referred as Single user MIMO, Multi user MIMO also referred as MU-MIMO. As the receiving devices are very close, the system works based on feedback from the individual devices.
