Detailed Description

This model provides means for simulating the following propagation phenomena in the presence of buildings:

shadowing (indoor, outdoor)
external wall penetration loss
internal wall penetration loss

The distance-dependent component of propagation loss is deferred to derived classes which are expected to implement the GetLoss method.

Warning: This model works only when MobilityBuildingInfo is aggreegated to the mobility model
