USRP Experiment 3: Using Airprobe Intercepting GSM Traffic
2011-09-13
Today, I did a experiment about intercepting GSM traffic. That was more interesting than I thought before. I could receive BTS downlink data and find out cell phone's TMSI and IMSI. Oh~~~yeah.
have fun on it!!

How to do?
I used USRP1 and DBSRX hardware to receive signal from the air. using GNURADIO and Airprobe to demodulate and decode.
The process is complex and I have a lot of unknown knowledge about this system. So, I can't write it now.
And I promise to sum it up and feel free to write the steps here.
