Key technical improvements behind Wi-Fi 6 ax performance

Wi-Fi 6 achieves its speed, efficiency and capacity gains through several new and improved technologies:

Orthogonal Frequency-Division Multiple Access (OFDMA)

  • Allows more data to be transmitted at once by splitting channels into smaller sub-carriers.
  • Enables simultaneous transmissions to multiple devices for increased throughput.

Multi-user, Multiple-Input, Multiple-Output (MU-MIMO)

  • Allows simultaneous data transmission to multiple devices at once.
  • Significantly increases network capacity.

1024-QAM modulation

  • Allows faster top transfer speeds by encoding more data in the signal.
  • Enables higher throughput at longer ranges.

Target Wake Time (TWT)

  • Scheduling transmissions efficiently reduces power consumption.
  • Extends battery life on mobile devices.

BSS Coloring

  • Differentiates signals from different access points.
  • Reduces interference and collisions as more routers are added.

Together, these capabilities add up to a major leap over Wi-Fi 5 and Wi-Fi 4. For home users looking for the best Wi-Fi performance, Wi-Fi 6 is the new standard.
