11:30 a.m.
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? As far as i understand the specification,
UMA is GSM Layer 3 over an GPRS/IPSEC tunnel to the BSC, so all the
GSM-Goodies should be there.
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.
