Formula
Calculation logicFormula definitions and substituted values.
Free-space path loss (dB)
32.44 + 20 * log10(Frequency (MHz)) + 20 * log10(Path length (km))
32.44 + 20 * log10(Frequency (MHz)) + 20 * log10(Path length (km))Estimated received power (dBm)
Transmit power (dBm) + Transmit antenna gain (dBi) + Receive antenna gain (dBi) - (Free-space path loss (dB) + Other path losses (dB))
Transmit power (dBm) + Transmit antenna gain (dBi) + Receive antenna gain (dBi) - (Free-space path loss (dB) + Other path losses (dB))Related calculators
