Visiting you site, we found a GSM RSSI software
working in a phone.
Can we use it in 904 Mhz ? This is the uplink GSM ARFCN channel 70.
It is possible ?
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.
