    Hi everyone,

    I have a question regarding A-MPDU in 802.11n.

    Can any one clear me why the duration ID in all the MPDUs of an A-MPDU are the same?

    Thanks

    I could be wrong here... but think of it as all the MPDU's are packed together into a single mass glob called an A-MPDU...hence when it is sent, it is sent with one duration ID value because it is seen as one "piece".

    Hope that helps...it really can be confusing
