Hi Remi, Maybe you can work something out from this slides: http://www.stanford.edu/class/ee359/lectures.html
Regards, -- Wojtek 2009/6/18 Rémi Villé <[email protected]> > 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. > > _______________________________________________ > Tinyos-help mailing list > [email protected] > https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help >
