3.2 Wi-Fi 6

CC33xx supports IEEE 802.11ax standard popularly known as Wi-Fi 6. Some of the Wi-Fi 6 features are listed below:

  • Orthogonal frequency division multiple access (OFDMA) - In Wi-Fi 6, the number of subcarrier frequencies per channel have increased to 4X and subcarrier spacing has been reduced to one fourth the subcarrier spacing of previous 802.11 revisions. This allows for much better equalization, enhancing channel robustness and performance.
  • Trigger Frames – This is a technique in which the AP sends a trigger to all connected stations so that they all send data simultaneously. It is used in uplink OFDMA to coordinate clients transmitting to the AP at the same time as well as in TWT.
  • Target wake time (TWT) - This feature enables Wi-Fi 6 devices to sleep more efficiently compared to legacy Wi-Fi 6 devices. A Wi-Fi 6 AP can negotiate with the participating STAs the use of the Target Wake Time (TWT) function to define a specific time or set of times for individual stations to access the medium. This results in much better and more efficient implementation of power save mechanism, directly resulting in extended product battery life.
