Hi Remi,

Maybe you can work something out from this slides:

> 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.
