To calculate free space path loss for isotropic antennas, follow the given instructions:
Take the square of the wavelength of the carrier wave.
Multiply the distance between the transmitter and receiver antennas by 4π, and take the square of the result.
Divide the value from step 1 with that of step 2.
Congrats! You have calculated the free space path loss for isotropic antennas.
