[ns] UMTS and 802.11

[Giovanni Bisegna]

Hi ns-users,
i try to simulate a wireless scenario with two different technologies 
at the same time.
I have to use 802.11 and UMTS (i'm using the Alfredo Todini and 
Francesco Vacirca UMTS patch) in the same simulation, but 
i can't. Why? Is possible that the problem is that 802.11 and UMTS 
use two different propagation model? And how i can resolve it?
Thank you in advance.
