Simple Module Ieee80211MgmtAPSimplified

Package: inet.linklayer.ieee80211.mgmt
File: src/linklayer/ieee80211/mgmt/Ieee80211MgmtAPSimplified.ned

C++ definition: click here

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 MACRelayUnit which performs bridging of Ethernet frames. This module will perform conversion from/to EtherFrame for MACRelayUnit.

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

from MACRelayUnit; can be left unconnected

uppergateOut output

to MACRelayUnit; can be left unconnected

macIn input

from Ieee80211Mac

macOut output

to Ieee80211Mac
