Required Database

Categorize buildings into different elements and specify their material parameters for accurate indoor propagation modeling.

The basis for any propagation model is a database which describes the propagation environment. For indoor propagation modeling, each building element is categorized into classes (for example, wall, floor, door) and specified by its coordinates and finally its material properties (thickness, permittivity, conductivity).

To get a more accurate description of wave propagation, the building data are stored in a 3D-vector format including all walls, doors, and windows. All elements inside the building are described in terms of plane elements. Every wall is, for example, represented by a plane and its extent and location is defined by its corners. Also, for each element individual material properties can be taken into account. It is also possible to import .dxf files, a common data format in architecture. Figure 1 shows an example for a three-dimensional building database used in ProMan.
