The propagation loss is fixed for each pair of nodes and doesn't depend on their actual positions.
This is supposed to be used by synthetic tests. Note that by default propagation loss is assumed to be symmetric.
ns3::MatrixPropagationLossModel is accessible through the following paths with Config::Set and Config::Connect:
No TraceSources are defined for this type.
Size of this type is 96 bytes (on a 64-bit architecture).
