Hi,
I looked in one of the cwne references and found a differing comment. Maybe on of the CWNEs can clear this up.
In the 802.11 ieee handbook it says on page 49 that the CF-Ack frames uses the null function data frame format, which it lists as having 28 bytes. I would guess that since all of these frames are directed between the AP and station they would not need to use the address 4 field and since there is no data then no frame body. Thus if you add up the remaining fields of the data frame format you get 28 bytes. Not sure where the extra 1 byte comes from.

It also says that all of the frames you listed above use this format.

29 or 28??

Best of luck for both of us with the exam
