| 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

- 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.
