Does anybody happen to have some good reference for this one? Something 
like: "The failure of poisson modelling of mobile wireless links" or 

What I have seen so far, simply assumes the contrary and uses Gilbert 
Markov Models and the like.

Actually, this fails to model even a scenario where a user is waiting 
for a bus at the bus station and talking to someone else with his mobile
and walks around a bit, one step to the left (broken connection) or to 
the right (excellent connectivity).

Although this seems rather obvious to me, I don't know a paper, or a 
well accepted text book, which explicitely states that Gilbert Markov 
Models and the like are theoretically appealing, but do not reflect reality.

I would appreciate any hint here.
