Create and Visualize 802.11ax Multinode Residential Scenario

WLAN Toolbox™ features enable you to create and visualize an IEEE® 802.11ax™ multinode residential scenario with any number of floors and rooms. Using this example, you can:

  • Create and configure a multinode 802.11ax residential scenario consisting of two floors, one access point (AP), and two stations (STAs) per room.

  • Assign random positions to the STAs and AP.

  • Visualize the residential scenario in 3-D.

Create and Visualize 802.11ax Multinode Residential Scenario with Two Floors

To access the helper files that this example uses, add the mlWLANSystemSimulation folder to the MATLAB path.


Create a simulation scenario by specifying the number of rooms in each floor. This example uses two rooms in x-, y-, and z-directions.

ScenarioParameters = struct;
ScenarioParameters.BuildingLayout = [2 2 2];

Specify the length, width, and height of the room in meters.

ScenarioParameters.RoomSize = [10 10 10];

Specify the number of STAs per room. This example contains one AP and two STAs per room.

ScenarioParameters.NumRxPerRoom = 2;

Assign random positions to APs and STAs by using the hDropNodes helper function.

[apPositions,staPositions] = hDropNodes(ScenarioParameters);

Obtain the medium access control (MAC) and physical layer (PHY) configuration of APs and STAs and the application traffic configuration of the transmitting nodes by using the hLoadConfiguration helper function. This helper function also assigns identifiers (IDs) and positions to all of the nodes in the network.

[nodeConfigs,trafficConfigs] = hLoadConfiguration(ScenarioParameters, ...

Create transmitter and receiver sites from the node configurations by using the hCreateSitesFromNodes helper function.

[txSite,rxSite] = hCreateSitesFromNodes(nodeConfigs);

Create a residential triangulation object by using the hTGaxResidentialTriangulation helper object. This object specifies the building parameters of the residential scenario.

triangulation = hTGaxResidentialTriangulation(ScenarioParameters);

Visualize the 802.11ax multinode residential scenario by using the hVisualizeScenario helper function.


Figure contains an axes object. The axes object contains 28 objects of type patch, line, text, scatter. These objects represent AP, STA.

At the end of the simulation, remove the mlWLANSystemSimulation folder from the path.
