    I've seen it on the practice tests, but not in the book.

    What is it please?

    Thanks,

    I found it in another question's explanation:

    Null Function ?¡é?€?¡° allows stations with nothing to transmit to complete a frame exchange. Can inform an Access Point of a change in power save mode. Also used to answer a CF-Poll frame sent by an Access Point operating as point coordinator in PCF mode.
