I used this function to compute gain from distance between A and B : Gain = -10*n*log(dist(A,B))
with n (Path loss exponent) = 4 (indoor) It's very rough, it takes only into account path loss (partly), maybe it should more look like this : Gain = T + R + A + -10*n*log(dist(A,B)) - C where T is the Transmitter power, R the receiver sensitivity, A the gain added by the antenna and C a constant to be added in the path loss. My knowledge in physics of radio communication is close to zero, so I really don't know how to compute gain attenuation well. If someone could help me on this subject I would be grateful.
