Dear list,
I am currently trying to make an GPRS sniffer. So far I have google
around
and the closest application I found was from Security Research Labs
using
osmocom-bb from https://srlabs.de/gprs/. Looking at the presentation in
CCCamp 2011 (
http://events.ccc.de/camp/2011/Fahrplan/attachments/1868_110810.SRLabs-Camp-GRPS_Intercept.pdf)
it seems that the whole purpose of the osmocom-bb is to get the raw
data,
which is then sent to the decoding program and then to wireshark. Thus
is
it possible to use USRP and GNURadio to capture the raw signals instead
of
using osmocom-bb and Motorola phones? If it is possible can you let me
know
where and how should I approach this problem? Lastly, if you know a
better
approach to capturing the GPRS traffic please let me know. Any help is
greatly appreciated.
Sincerely,
Weiqing Li
