802.11ax introduced some changes that have real world effects: subcarrier spacing was decreased by a factor of 4. Symbol length was increased by the same factor, but that means receiver sensitivity requirements are looser for the same data rate. So, for the same signal strength you can get a higher data rate. I’ve personally seen this effect on my own phones and laptops: I get consistently higher throughput on ax networks than I do on ac.
