double inet::physicallayer::IdealObstacleLoss::computeObstacleLoss	(	Hz	frequency,
		const Coord &	transmissionPosition,

	)		const

overridevirtual

Returns the obstacle loss factor caused by physical objects present in the environment as a function of frequency, transmission position, and reception position.

The value is in the range [0, 1] where 1 means no loss at all and 0 means all power is lost.

Implements inet::physicallayer::IObstacleLoss.

overridevirtual

Prints this object to the provided output stream.

Function calls to operator<< with pointers or references either const or not are all forwarded to this function.

Reimplemented from inet::physicallayer::IPrintableObject.

 {
