Usage Guidelines

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

  • Only the 802.11ac wave2 APs support MU-MIMO on 5 GHz radios.

  • 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.

  • MU-MIMO is not supported on a Mesh network.

Example

# Enable MU-MIMO in the SSID profile test.
