The 802.11a/n radio profile allows upper or lower control channel. Is there a reason to use one or the other for anything besides channel planning? I vaguely remember hearing in training that I should always use lower.

Also noticed the 802.11a/n/ac profile allows 40MHz channel width but does not show options for upper or lower control channel. Is there a reason for that?
