Main Computation Methods

The three main computation methods for indoor databases in ProMan are the 3D ray tracing (SRT) model, dominant path model (DPM), and the multi-wall model (COST 231).

• 3D ray tracing (SRT) model

  This method is accurate but can be computationally expensive if many interactions are taken into account.

• dominant path model (DPM)

  This method is the right balance between accuracy and simulation time but not available with the fully polarimetric option.

• multi-wall model (COST 231)

  This method is fast but may be too pessimistic when a ray traverses multiple walls. Rays that diffract around corners are not considered.
