Detailed explanation-1: -The free-space path loss (FSPL) formula derives from the Friis transmission formula. This states that in a radio system consisting of a transmitting antenna transmitting radio waves to a receiving antenna, the ratio of radio wave power received to the power transmitted is: P r P t = D t D r ( 4 d ) 2.
Detailed explanation-2: -Friis formula or Friis’s formula (sometimes Friis’ formula), named after Danish-American electrical engineer Harald T. Friis, is either of two formulas used in telecommunications engineering to calculate the signal-to-noise ratio of a multistage amplifier.
Detailed explanation-3: -The Friis Transmission Equation is used to calculate the power received from one antenna (with gain G1), when transmitted from another antenna (with gain G2), separated by a distance R, and operating at frequency f or wavelength lambda.
Detailed explanation-4: -Explanation: Friss transmission equation is used to calculate the power received by the receiving antenna when transmitted from other antenna separated by a distance R.
