why do you think that? 'experimental license' != 'carrier license'. We've obtained this in Germany, Austria, Switzerland and the Netherlands. So at least in the EU it seems generally no problem The fees we had to pay for those experimental/test licenses are typically < 300 EUR, so much cheaper than the equipment that you need to run the network anyway. >From what I've heard about the US with regard to experimental licenses, they have a similar situation (see how OpenBTS folks managed to get licenses for their burining man tests). > - Is there some part of the official gsm bands that overlaps with local ISM > or other not-so-tightly-regulated frequencies? > (i.e, GSM1900 seems to have a small part that's not used by DECT...) This is a rumour. Only one of the uplink/downlink bands is in there, so you will still need a test license. Also, AFAIK the DECT band is not everywhere unlicensed for any kind of application, but actually restricted to be used with the DECT system. > - Are there any "standard" gsm handsets that could be modified (preferably > in software) to work at 2,4GHz? no. > - Is UMA/GAN (http://en.wikipedia.org/wiki/Generic_Access_Network) something > that could be used with OpenBSC?

You would have to implemet a UMA gateway and somehow glue that to the layer3 inside OpenBSC. I don't think you can do it cleanly with the current code. Later this year, once the new "real MSC" codebase emerges, this might be easier.
