You can choose the probability of indoor or outdoor associated to the transmitters and receivers. This will map later to the The percentage of transceivers being indoor and outdoor can be selected thanks to this panel.. It will work in combination with the chosen propagation model that you will select. By default the transmitter and receiver are located outdoor. For each elements of the link, it is possible to add Image Removed or remove Image Removed a   or remove   a probablity of indoor.Image Modified

As the

didn’t exist before version 5, a warning may appear indicating that “local environments are skipped for multiple

interfering links”. This means that SEAMCAT was not able to automatically set the

parameters of the local

).

Therefore, there is a need to edit the local environment manually.
