Below the link for the utilities:

Today, in some minutes, we have been able to scan: grgsm_scan and locate a connected gsm device.

You can note the frequence,

and then in a second command you can type: grgsm_livemon -f 927.8M

That will show in console the different GSM packets received,

Finally in a third window you can filter into wireshark to execute with the filter gsmtap.

wireshark -k -Y '!icmp && gsmtap' -i lo

We got very surprise to be able to get GSM traffic in the wireshark, ready to be analysed.
