This sounds extremely cool, although I have a feeling the regulators won't be too happy if I start broadcasting in the GSM band(s) with enough intensity to be useful.
- eagleal 17y agoNot if you implement this in a third-world country, where regulators can't enforce. (But, in a country like that, you may be forced with guns to shut down :P)

- chronomex 17y agoThe downlink (tower -> phone) band used outside the US lies partially inside the ISM band in the US. I'm not exactly sure about the legality of it, but you can use OpenBTS to transmit only in the ISM band and a quadband telephone will transmit the other direction somewhere rather outside it. You might be able to argue that the phone is out of spec to transmit in that band within the US. What I do know for sure is that I've done this in two places and the FCC Mobile Death Squad hasn't come over for a visit.
- dedward 17y agoYou generally won't find a death squad - but when something starts misbehaving on a licensed cellular frequency, the cellular providers will be the first ones to show up at your door to find out what's going on - and they'll only do that if something actually causes them a problem.
- biafra 17y agoYou have to get a license to do that. At the "Hacking at Random" and the last "Chaos Communication Congress" we had "testing" licenses with restrictions about signal strength and height above ground for installing the BTSes.
