GPRS Vs EDGE - Trying to decode my own sessions

Hi Sylvain,

as i understood, Luca made some tests with real networks in Italy, infact as he stated during the talk, Wind [222-88] and Tim[222-01] (two 
providers) are using GEA/0.

Assuming it, i wanted to make some tests, trying to dump my own sessions while using a Wind's sim.

Unfortunately i'm having some issues due gprs is continuously upgrading to EDGE and not having an old "gprs-only" phone, the only solution that i'm trying is to force it to remain in gprs-mode by reducing the gain and creating noise with the usrp.

Btw... what i was curious to know is... also Luca, while testing its own sessions, was not able to see other third-party gprs sessions on the air?

I know that almost all real users are using EDGE or UMTS, but how is possible that no one gprs session is available?! 
I'm not interested on third-party sessions, i'm just trying to understand if it is working well or it is having a strange behaviour and there is something to patch.

P.S: Of course i would like to test it with my own test set, but at the moment i cannot.

Regards,

Luca
