Is it possible to use the Poynting Theorem to calculate this distance? i mean, I know the TX power and the RX power aswell, and i could use the formula
Prx=(Ptx*G)/(4*pi*R^2) .... where Prx is the RX power, Ptx is the TX power, and G is the TX antenna gain.
I also thought of the possibility of sending a signal and compute the time it takes to get to the receiver...but i do not know how to do that.
Thanks for your help!
