問題文
A capture from a modern BSS is opened on a laptop whose stations are much older than the AP. Those older stations still manage to stay off the medium for the right length of time, yet they cannot use any of the newer features. Which pairing states which part of the transmission they can still read and where the newer capabilities are carried?
