Member Function Documentation

double inet::physicallayer::ParabolicAntenna::computeGain ( const EulerAngles  direction ) const

overridevirtual

Returns the antenna gain in the provided direction.

The direction is relative to the antenna geometry, so the result depends only on the antenna characteristics. For transmissions, it determines how well the antenna converts input power into radio waves headed in the specified direction. For receptions, it determines how well the antenna converts radio waves arriving from the the specified direction.

Implements inet::physicallayer::IAntenna.

{
    return std::max(minGain, maxGain * math::dB2fraction(-12 * pow(direction.alpha / math::deg2rad(beamWidth.get()), 2)));
}

virtual double inet::physicallayer::ParabolicAntenna::getMaxGain ( ) const

inlineoverridevirtual

Returns the maximum possible antenna gain independent of any direction.

Implements inet::physicallayer::IAntenna.

{ return maxGain; }

void inet::physicallayer::ParabolicAntenna::initialize ( int  stage )

overrideprotectedvirtual

Reimplemented from inet::physicallayer::AntennaBase.

{
    AntennaBase::initialize(stage);
    if (stage == INITSTAGE_LOCAL) {
        maxGain = math::dB2fraction(par("maxGain"));
        minGain = math::dB2fraction(par("minGain"));
        beamWidth = degree(par("beamWidth"));
    }
}

std::ostream & inet::physicallayer::ParabolicAntenna::printToStream ( std::ostream &  stream, int  level  ) const

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::AntennaBase.

    stream << "ParabolicAntenna";
    if (level <= PRINT_LEVEL_DETAIL)

               << ", minGain = " << minGain
