Note the Wi Fi 6 whitepaper in middle of document. More technically dense but still way more readable than the standards docs: https://www.cisco.com/c/dam/en/us/products/collateral/wireless/white-paper-c11-740788.pdf https://poal.co/s/Computers/90463 These are probably the best and least 'tech writer making shit up' or misunderstanding, of all the docs out there with out going too far or being too political.
