Member Function Documentation

double ns3::FriisSpectrumPropagationLossModel::CalculateLoss	(	double	f,
		double	d
	)		const

Return the propagation loss L according to a simplified version of Friis' formula in which antenna gains are unitary:

 (4 * pi * d * f) ^ 2

L = -------------------— C^2

where C = 3e8 m/s is the light speed in the vacuum. The intended use is to calculate Prx = Ptx * G

Parameters

f	frequency in Hz
d	distance in m

Returns

if Prx < Ptx then return Prx; else return Ptx

Ptr< SpectrumValue > ns3::FriisSpectrumPropagationLossModel::DoCalcRxPowerSpectralDensity ( Ptr< const SpectrumValue >  txPsd, Ptr< const MobilityModel >  a, Ptr< const MobilityModel >  b  ) const

virtual

Parameters

txPsd	set of values vs frequency representing the transmission power. See SpectrumChannel for details.
a	sender mobility
b	receiver mobility

Returns

set of values vs frequency representing the received power in the same units used for the txPower parameter.
