Propagation Models
|
The tunnel scenarios are saved in
WinProp's indoor building
database format. Therefore all indoor
propagation models can be used.
Due to the multiple reflections and waveguiding effects, especially
deterministic and ray-optical propagation models are recommended.
The following propagation models can be used:

Time-Variant Scenarios
|
Inside tunnels the time-variant objects (e.g. cars, trucks, trains,...)
have a significant effect on the wave propagation. Shielding and
waveguiding are depending on the obstacles inside the tunnels. If the
obstacles are moving, the propagation environment changes
significantly.
Therefore WinProp offers a time-variant propagation
module to consider these time variant effects even in tunnels.
