Out of curiosity how quickly could you log into wifi, check for whatever on the wifi, and turn off? Can you do that every 200 ms and have the wifi off most of the time? Is that what cell phones do already?

Mostly just curious about minimizing energy usage due to wifi.



You stay associated, but other than that: yes.

Logging entirely out and back in every 200 ms would be bad, because associating is expensive and it probably takes longer than 200 ms, at least if you also want to do anything useful.
