RES: osmocom

Harald, No. This not a open hardware / open source project. It is for car localization, in case of jammer use, that blinds the GPRS modem. We tried to sniff that frequency, but was impossible, due the saw filters in the GPRS modems (that only allow the to receive the uplink channel), and for economic reasons. We to make a 20 units like this and we have a reduced budget. Do you think that is possible ? How much you think will cost a solution like that ?

Yes, in general this is possible. You will have to remove the receive filter of the phone, as it is described in http://bb.osmocom.org/trac/wiki/Hardware/FilterReplacement and replace it with soem baluns. Please also note that the measurements at the moment are completely uncalibrated. If you need precision, I would suggest to calibrate each phone individually. -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
