Indoor scenarios have the most detailed geometry descriptions, with exterior walls, windows, interior walls, doors, and whatever else is relevant. Object dimensions are typically much larger than a wavelength, since WinProp uses high-frequency and empirical methods.

Figure 1. Example of an indoor database with walls made of different materials, with doors and with windows.

Furniture and people can be included explicitly, but are more often defined by assigning a larger attenuation to specific volumes.

Figure 2. Extra attenuation occurs in areas with furniture and people, without the need to specify the geometrical details.

Indoor scenarios are not limited to buildings. WiFi coverage in an aircraft is also a regular indoor scenario. The aircraft is usually defined in WallMan.

In special non-indoor cases one can, if desired, include a significant amount of geometrical detail and save the geometrical database as an indoor database. This is sometimes done for vehicle-to-vehicle or vehicle-to-infrastructure communication, or for propagation in a stadium.

Figure 3. A open-air stadium is defined as an indoor database to have the freedom to define any geometrical shape.

In the case of communication in tunnels, the tunnel geometry is usually built in TuMan and optionally enhanced in WallMan.
