Ieee80211MgmtAp

simple module

Used in 802.11 infrastructure mode in an access point (AP).

This module expects Ieee80211MgmtSta modules to be resent in the stations.

This module never switches channels, that is, it will operate on the channel the physical layer is configured for (see channelNumber in Ieee80211Radio).

This module relies on a connected Ieee80211Mac for actual reception and transmission of frames.
