Are you sure that this is completely legal?

I vaguely remember that, if you could impersonate a BTS, you can crack a GSM SIM and clone it in no more than 6 hours.

I don't see any problem in access the OpenBTS web site (that sooner or later will contain schematics, source code, ecc..) for people living in the first world.

You'd need a license to turn the thing on, since GSM operates on regulated frequency bands.

Well if you have a hacksaw you can spend a couple minutes and steal any bike or break into any warehouse that you please. You'd be amaze how fast a 15 year old boy can hack through a thick steel cable.

I would think it would be completely legal if you have a radio operators license of some sort. I mean it's not like the government can make it illegal for people start their own cellular phone companies.

At least in Europe, companies have paid governments a lot of money for licenses to use the GSM band and governments protect their investments (and network health and security) not allowing anyone else to use the GSM band.

If you get a amateur radio licence, you are allowed to use some spectrum
near the GSM band, mabe that is a solution?

Hi, pcampe.

As the guy who filed the FCC application for the Burning Man GSM test, I can tell you that what we
did was completely legal. Our license was WD9XKN, STA file #0353-EX-ST-2008, good for one
week in an area 10 miles NE of Gerlach, NV. We also coordinated spectrum use with a licensed
cellular carrier in the area. All of this is presented in the project web page.

What you describe is an IMSI-catcher. That's not what we were doing.

Thanks for your quick explanation and good luck with your project.
