Free Space Loss
Attenuation of the electromagnetic wave while propagating through space. This attenuation is calculated using the following formula:
Free space loss = 32.4 + 20xLog(FMHz) + 20xLog(RK m)
F is the RF frequency expressed in MHz.
R is the distance between the transmitting and receiving antennas (expressed in Km).
At 2.4 GHz, this formula is: 100+20xLog(RK m)
