Fading of what?
Sound amplitude? Light intensity? Mobile what?

fading in terms of loss in transmission intensity caused by changes in the transmission medium

mobile as in cellphone/handphone

Here's another avenue to investigate: http://en.wikipedia.org/wiki/Computation_of_radiowave_attenuation_in_the_atmosphere

I see that both the International Telecommunication Union (ITU) and Nasa's Jet Propulsion Laboratory (JPL) have published papers on the subject. These are likely to have been generously funded and I would guess, quite useful for the basis of computations. michaelmel's soulution is (almost certainly) the better answer.

As a wild guess I would say that you should use Rician fading model for indoor settings and Rayleigh model for outdoor.

But if you want a real answer, consult a relevant book such as W. Stallings Wireless Communications.

Not quite the forum for this, really....
