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.
