The mu-mimo disable command disables MU-MIMO.
The undo mu-mimo disable command enables MU-MIMO.
By default, the MU-MIMO function is enabled.
Usage Scenario
Carrier sense multiple access with collision avoidance (CSMA-CA) allows an air interface channel to be occupied only by one STA, and other STAs cannot communicate with the AP. After MU-MIMO is enabled, STAs supporting MU-MIMO can form an MU group to simultaneously receive downlink data from the same air interface channel, improving channel efficiency and overall downlink throughput.
Precautions
In WDS scenarios, ensure that the number of spatial streams on STA VAPs is smaller than that on AP VAPs. Otherwise, MU-MIMO cannot take effect. For example, if STA VAPs and AP VAPs are both configured with three spatial streams, an AP VAP can communicate with only one STA VAP even if MU-MIMO has been enabled.
After MU-MIMO is enabled, the beamforming function of the radio where VAPs are located is enabled and is not subject to the beamforming enable command. When MU-MIMO is disabled for all VAPs on the radio, the beamforming function is subject to the beamforming enable command.
