Hello everyone,

I have calculated the received power for free space optic (FSO) using the equation:

Lsystem (system loss) is set to 8dB. PTotal can be calculated as:

where Ntx (number of receiver) = 1 and PTx (transmitted power) =7.78 dBm. LGeo can be calculated as:

where d

The problem is, I got received power=10.72 dBm which is illogical value. As I know, the received power must be lower than transmitted power.

I hope that anyone may help me to understand this situation.

For your information, I refer this paper for the calculation: https://ieeexplore.ieee.org/document/6015903

Thank you.

^{2R}(receiver diameter) = 0.07, l=1, θ (divergence angle) =0.05 and Nr (number of receiver) =1.The problem is, I got received power=10.72 dBm which is illogical value. As I know, the received power must be lower than transmitted power.
