Mm Bsd mmbsd1982 at yahoo.comHello, I am using a SDR device (a BladeRF) and there is a nice tool called 'kal' that will show me all of my nearby GSM base stations. In addition to listing base stations and their frequencies, I could also use that frequency info to monitor the beacon channel with gr-scan/airprobe. So at this point I know: - base station exists - I know its frequency - based on beacon channel assignments, etc., I *sort of* know how busy it is. But what else can be learned about a particular base station with simply passive observation and no decryption (and no sim card) ? If all I have is a passive monitor with a SDR, what else can I learn frmo the beacon channel or from the station itself ? Is it possible to learn things like software version, protocols supported, connectivity to network, or to other base stations ? My goal is to learn about the GSM networks around me and I wonder how deeply I can understand them with just passive observation of the beacon channel (or other sources of info that can be seen with SDR). Thank you.
