Great video for explaining the basics, doing a report on 802.11ax modulation and coding schemes and you managed to condense about 5 hours of reading into a short video. Thank you very much.

Wasnt 2048 and 4096 used at the time of release of this video? How crazy is that compared to 256 qam?

great video, I finally understand whats happening! I think at 4:00 you accidently switched the phases of 1001 and 0100, right?

How to calculate the capacity of a link that uses QAM modulation. Is there a formula for the calculation?

The amplitude is the length of the line, so it's neither 25 or 75.

what about spatial streams have different received power?
