Ieee80211MgmtApSimplified

simple module

Used in 802.11 infrastructure mode: handles management frames for an access point (AP). It relies on a connected Ieee80211Mac for actual reception and transmission of frames.

This management module variant does not implement beacons, probes, authentication and association -- it simply treats all stations as associated all the time. This also means that you cannot use this module in a simulation that involves handovers; for that you need to use the full version, Ieee80211MgmtAp.

When simulating an AP that has other (Ethernet or wireless) interfaces as well, this module can be connected to a IMacRelayUnit which performs bridging of Ethernet frames. This module will perform conversion from/to EtherFrame for IMacRelayUnit.

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 checks if there is an other module connected above the management module (e.g. RelayUnit) and sends a copy of the frame there and at the same time sends the frame back to the wireless interface. The relay unit will send it out on the interface which is towards the destination or will broadcast it on all interfaces (except on which it was received).
