Modelize the propagation loss through a transmission medium.
Calculate the receive power (dbm) from a transmit power (dbm) and a mobility model for the source and destination positions.
ns3::PropagationLossModel is accessible through the following paths with Config::Set and Config::Connect:
No Attributes are defined for this type.
No TraceSources are defined for this type.

int64_t ns3::PropagationLossModel::AssignStreams | ( | int64_t | stream | ) |
If this loss model uses objects of type RandomVariableStream, set the stream numbers to the integers starting with the offset 'stream'. Return the number of streams (possibly zero) that have been assigned. If there are PropagationLossModels chained together, this method will also assign streams to the downstream models.

Ptr< PropagationLossModel > ns3::PropagationLossModel::GetNext | ( | void | ) |
Gets the next PropagationLossModel in the chain of loss models that act on the signal.
This method of chaining propagation loss models only works commutatively if the propagation loss of all models in the chain are independent of transmit power.

void ns3::PropagationLossModel::SetNext | ( | Ptr< PropagationLossModel > | next | ) |
Enables a chain of loss models to act on the signal.
next | The next PropagationLossModel to add to the chain |
This method of chaining propagation loss models only works commutatively if the propagation loss of all models in the chain are independent of transmit power.
