11axOFDMA

802.11ax APs use Orthogonal frequency-division multiple access (OFDMA) technology to partition a channel into smaller sub-channels called resource units (RUs) allowing multiple users, with varying bandwidth needs, to be served simultaneously. OFDMA is ideal for low bandwidth applications and results in better frequency reuse, reduced latency, and increased efficiency.

When enabled, the AP mandates the RU allocation for multiple clients for both downlink (dl) and uplink (ul) OFDMA. A series of trigger frames are exchanged to allow multi-user transmission in the both directions - downlink and uplink.

Use this command to enable support for OFDMA in both or one direction. OFDMA support is disabled by default. Specify a guard-interval to avoid overlapping of OFDMA symbols.
