I have followed the instructions on http://openbsc.osmocom.org/trac/wiki/network_from_scratch, I'm using the jolly/testing branch of osmocom-bb and I've enabled TX support in the Makefile. The software runs on an xubuntu 14.04 x64 machine. After uploading the firmware to the phones RAM via osmocon, it shows that it's running osmocom-bb on the display, when I then try to run transceiver with the following parameters: -e 5 -r 99 (or alternativly -e 5 -a 958 to sync with german provider O2) the phone just reboots and goes into a state where the keyboard backlight is blinking with 0.5 hertz. The last thing "transceiver" says is: <0012> l1ctl.c:383 Reset received: Starting sync. <000c> l1ctl.c:95 Sync Req <000c> l1ctl_link.c:171 Sending: '01 00 00 00 83 be 00 64 27 10 03 20 03 07 00 00 00 ' and the last log messages from osmocon are: DSP API Version: 0x3606 0x0000 LOST 7200! L1CTL_RESET_REQ: FULL!L1CTL_FBSB_REQ (arfcn=33726, flags=0x7) Dropping sample ':' I'm not sure if I have configured the correct bands for synchronization. I think it might have to do something with that. I copy'd the default configuration from the osmocom-page stating DCS1800. The only base station I'm seeing here is 958, which is in the GSM900R range. Could this be the problem? Have I overseen something simple? Have I provided all necessary information about my setup? Any ideas? It's probably not a power issue, I have tested it with a lab power supply for providing the USB 5V and battery 4.2V, which resulted in the same behavior.

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).

Software Version is not a concept known to GSM, nothing about it or about the manufacturer will be broadcaster. Base Stations won't TX anything if they don't have connectivity to the network. And they also don't talk to other base stations at all. (at least not on a GSM layer). Not sure what you mean by "protocol supported" but you can definitely see if the cell supports GPRS/EDGE in the SI messages. As for other info you can obviously get the operator, location area id and cell id (and cross reference with opencellmap for instance). You can also follow the assignements and the first few messages are not ciphered and you can see if/how authentication is done and or what kind of service is requested. > 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). Just look at all the System Informations messages in wireshark and look at each field and the corresponding documentation for it in the spec to know what they mean. ( GSM 04.08 will contain most of it ). That's pretty much how I learned a lot.

I'm sorry to announce that the OpenAirInterface presentation on October 15 has ben CANCELLED. The reason is some schedule changes imposed on the speaker. There is a chance that we will be able to re-schedule the event at some point in November. Once that has been cleared up, there will be a separate announcement. The next regular Osmocom Meeting Berlin is scheduled for October 21 at the usual location (CCC Berlin), looking forward to meeting you there. -- - Harald Welte ============================================================================ "Privacy in residential applications is a desirable marketing option."

(snip) Not sure what you mean by "protocol supported" but you can definitely see if the cell supports GPRS/EDGE in the SI messages. Ok, thank you. Are all SI messages sent in the clear (unencrypted) and are they all available to a passive observer with just software radio (no phone or sim card) ? As for other info you can obviously get the operator, location area id and cell id (and cross reference with opencellmap for instance). You can also follow the assignements and the first few messages are not ciphered and you can see if/how authentication is done and or what kind of service is requested. Ok, and am I correct that by watching the volume of assignments (and maybe the volume of paging requests) a person could estimate the traffic, or utilization (or at least relative utilization) of that tower ? > 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). Ok, I will be looking at SI messages and those SI messages all take place on one fixed beacon channel, correct ? Thank you.
