Combination of Urban and Indoor Vector Databases

The WinProp suite offers a powerful way to model the coverage of transmitters in an urban environment in single buildings. Indoor databases with their higher grade of detail can be imported in an urban database. These indoor databases must contain a shape around the building.

When reaching the shape of the building, the urban propagation model switches to an indoor model and when a propagation ray leaves the building it switches back to the urban model.
