  - Radio Coverage Solution
    This example considers the application of analyzing a Wi-Fi router in a building.
    - Example Overview
      This example shows how to define and set up a radio coverage solution in Altair SimLab. The model is a single-storey building with doors and windows, solved using the Dominant Path model (DPM). The model is solved and the results are displayed.
    - Topics Discussed in this Example
    - Example Prerequisites
      Before starting this example, ensure that the system satisfies the minimum requirements.
    - Launching and Configuring SimLab
      Open SimLab and configure SimLab to only show the tools relevant to the selected solution.
    - Navigating the Graphics Window
      The graphics window is used to display and interact with the model. You can zoom, rotate and pan a 3D model using the keyboard, mouse, or a combination of both.
    - Defining the Sketch Plane
      Set up the XY plane as the sketch plane. The floor plan will be drawn on this plane.
    - Setting the Model Units
      Change the model units to meters, kilograms, and seconds.
    - Creating the Building Geometry
      Use 2D sketches to define the building floor plan, doors, and windows. The sketches are realized as single sheet bodies to create the building geometry.
      - Creating the Floor Plan
        Create the floor plan of the building using a sketch. This sketch will be used to create the building geometry.
      - Creating the Floor
        Create the floor using the sketch Floor plan.
      - Creating the Walls
        Create the walls of the building by extruding the floor plan.
      - Creating the Ceiling
        Create the ceiling of the building.
      - Adding Doors and Windows
        Create the doors and windows of the building.
    - Adding Material Properties
      To add material properties to the ceiling, doors, floor, windows and walls, the materials first need to be loaded from the Material Database. A property can be defined and assigned when the material is loaded into the model.
    - Hiding Selected Objects in the Graphics Window
      To make placing the antenna in an upcoming topic easier, hide the ceiling for now.
    - Defining a Radio Coverage Solution in SimLab
      Create a radio coverage solution for the model (bodies).
    - Adding an Antenna
      Add a Wi-Fi antenna to the model.
    - Adding a Prediction Plane
      Define a prediction plane where the results are to be predicted when running the WinProp Solver.
    - Specifying the Propagation Model - DPM
      Select the Dominant Path Model (DPM) as the computation method.
    - Defining the Result Requests
      Specify the predictions to be computed.
    - Solving the Model
      Compute the propagation for the antenna to obtain the prediction results.

Creating the Walls

Create the walls of the building by extruding the floor plan.

In the Assembly Browser:

Duplicate Floor plan using the right-click context menu.
Rename the duplicate to Wall using right-click context menu.
Click Wall, and from the right-click context menu, click Extrude as Sheet Body.
On the pop-up dialog, specify a height of 3 m.

The result is the following:
