Anyone working on any "ad hoc GSM/LTE" startups, or developed any business models around them? This technology is very interesting but I'm puzzled about what I would use it for.
Does anybody know some nice software radio materials? In form of lectures or lab exercises? I was always wondering about background of people which make feats like this. I have a degree in EE, oriented toward telecommunications but would not be able to produce something similar.
Maybe a dumb question but I don't see any mention of frequencies/power they use to test in the wiki.<p>I'm a little fuzzy on cell bands but I thought they were all restricted(lots of ham gear has cell bands explicitly locked out).
If anyone's interested in UE side, I recommend srsUE as a more functional open source implementation of LTE stack. There's also Open Air Interface, which has both Ue and eNB, but is less stable.
