You can choose the probability of indoor or outdoor associated to the transmitters and receivers. This will map later to the 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 or remove a probablity of indoor.

You can edit the field by double cliking

Description | Symbol | Type | Unit | Comments |
Local environment: Receiver | Indoor/ outdoor | - | - | Environment of the receiver antenna: outdoor, indoor It is used for both VLR and ILR |
Local environment: Transmitter | Indoor/ outdoor | - | - | Environment of the transmitter antenna: outdoor, indoor It is used for both VLT and ILT |
Probability | - | S | % | Probability that of a Tx or Rx to be indoor or outdoor |
Wall loss | or | S | dB | The attenuation due to indoor-outdoor external walls associated to the propagation model tha you have selected for the transmitter or the receiver |
Std. dev. | or | S | dB | Wall loss stdandard deviation (indoor - outdoor) Wall loss standard deviation associated to the propagation model tha you have selected for the transmitter or the receiver |
Note that when you open a workspace produced prior to SEAMCAT version 5.0.0, it is migrated to the newest SEAMCAT version you will have installed on your machine. In the case of the local environment, you may have the following warning that “local environments are skipped for multiple interefering links”. This means that SEAMCAT was not able to automatically set the paramters of the local environment (most likely due to multiple interferers scenario). You will have to edit the local environment manually.
