What a great job! I've only recently discovered this OS and I love how well it works and all the possibilities it offers. I had an Ubuntu 16.04 set up with several GPS and GSN tools and I kept having problems with the Ettus B210, but what you have created, my friend, is a real marvel. The only thing is that I am not able to make it work with the "SOS" system of my car, since, as you say, OpenBTS automatically picks up the IMSI, although I have tried to set it up manually, I can't get it to connect automatically to the system. Thanks for all your work.
OpenBTS or the other GSM related tools can be set to open registration, but whatever is connecting needs to have gsm capabilities in the bands you’re setting, need a sim, and will at first most likely have to be told to connect manually unless you configure the bts to look like a “real” network. Glad you’re enjoying it so far!
@@cemaxecuter7783 Yes, the system has its own SIM for calls and the "SOS" system and uses the E-GSM network (900 MHz). I have tried connecting it to an Amarisoft system by configuring the subscription data and it does so without any problems.Thx.
That’s really interesting. What if you use the osmo-nitb scripts and configure them first for the band you need. It’s set to open registration by default.
@@cemaxecuter7783 I have the configuration files with the values as they were: GSM900. Using several mobile phones, from different companies, when searching for the 2G network and choosing it manually, they connect without any problems. I have tried to link the "SOS" module directly to the 2G network in an area with poor coverage and it does not connect. Should I add the IMSI to Asterisk to make it easier? THX
Will an Ettus USRP1 based SDR work with Osmo-NITB? Also, compared to OpenBTS, it seems that Osmocom has EGPRS/EDGE support along with private caller ID.
Most likely yes, but with the osmo-nitb scripts in latest DragonOS FocalX there’s a separate python script for uhd and it requires one additional step that I swear I always forgot to document. I’ll have to remind myself what that is again.
Is Pluto + compatible with the software used in your video? I mean it works with the same frecuency and is full duplex, but not sure with the software part, have a nice day.
Not for the gsm base station videos, but there was an extensive guide on modifying the regular Pluto for srsRan. The Pluto+ will work for other software that generally supports the regular Pluto.
Thank you for good contents. I have some question. How can I do this practice with usrp-2901? I tried but it's not working on version R31. What version should I have to do with?
I would think with the usrp you could run maybe the osmo bts scripts in r31 or also OpenBTS that’s included. There’s a small gotcha with the osmo bts scripts though, as you have to start the application with the .py file but then also pull up another terminal window and run sudo osmo-trx-uhd -C /etc/osmocom/omso-trx-uhd.cfg
Thank you for this, works well with Limesdr mini 2.0 on DragonOS. One thing though, have you got GPRS/EDGE to work? I've been unable to yet. From what I understand it should be enough to add the command --gprs -i followed by the network interface, then just set the APN on the phone to internet. Just no luck with that yet.
@@cemaxecuter7783 Thank you! Yeah, it is quite slow, by default I think it was only 2 timeslots used for data by the bsc config file. For some reason I'm just unable to get even the G or E to pop up, and no uplink going from the phone to try to indicate get the data connection. I have another older distro in a vm, and a version of osmo-nitb, and it works fine on it though. I have compared the config files etc. and just can't figure out. Everything else works fine though, sms, calling..
Okay this weekend I can dig into it and see what the difference is. I do recall it working in maybe the 20.04 version of DragonOS, you can still grab i from source forge by gettin the r26 version.. but now thinking about it the mini v2 won’t work on that version.. darn
@@cemaxecuter7783 Thanks. I will give a try for the 20.04. Lime v2 should be compatible with everything that the older v1 is, if i'm not mistaken(?) At least with that older premade VM it worked out of the box, without updating anything.
Thanks for the great work. I am able successfully run the BTS with E200 SDR. But i would like to know about the Multiple ARFCN Mode feature in osmo-trx. How i can i utilize it to create 3 base station network using the just single channel. Is it possibly? Will we see the three Networks on our device search or only one network if we configure the Multi ARFCN Mode correctly? I need some clarification on thie feature. Thanks again for your all great work.
Hello. Will it works when I use 2 HackRF One devices ? 1 HackRF One for ONLY TX and second HackRF One for ONLY RX and change some codes fornit (instead of Bladerf or LineSDR)
Good evening! I can’t remember off the top of my head how far back this was included, but it’s been in there probably since the 10th release or so. If osmo-nitb folder is in usr/src/ then it’s probably all setup for ya.
No problem, so of the older builds may have the script setup for just the LimeSDR but nowadays it’ll work with some ettus SDRs like I mention in the video.
Most likely that was in the older DragonOS Focal sourceforge.net/projects/dragonos-focal/files/DragonOS_Focal_R26.iso/download In the latest I don’t recall adding this, but there’s various other ways Like this ua-cam.com/video/l8_EZ-0oSGM/v-deo.html Or this ua-cam.com/video/joo9OE8Ab60/v-deo.html
Weird noob question: could one set the downlink freq to be the T-GSM-900 band at 915.4 - 921MHz, which falls in the 902 - 928 ISM band, then legally (as long as you're under 1 watt) have a local cell network? Because even though the uplink is out of ISM range it would only be our (presumably) FCC approved phones transmitting on that freq... I'm probably ingnorantly optimistic but figured I'd ask.
I feel like I saw that talked about in a discord channel but I can’t remember what the end result was. There’s specific uplink, down links and I think like you mention some do fall in the ISM band, but then maybe it’s the uplink that’s right outside of it. I’ll ask around and see if anyone has some experience with doing such a thing.
I read this again and see you mentioned right there about the uplink and you being up a good point about the fcc and 1watt. I’m going to take most of this and ask the guys in the radio frequency hacker sanctuary channel.
I got this response back which is actually interesting and something I can do with two SDRs however, it’s srsRan and not gsm. But, I suspect you could probably do what your saying - however I don’t think the connection between phone and bts would be able to made except within a short range. “I've done that with srsLTE, set the UL to 2.4GHz and DL to 5.8GHz. Only worked with two SDRs but it's a way to play with the tech legally”
@@cemaxecuter7783 Awesome! Thank you, I do only plan on short range operation just to quench some curiosities. Also, I went down a hole looking into LTE on the 23cm and 33cm ham bands (encryption is an issue) and came across "Citizens Broadband Radio Service". It requires some registration, and usually some "cheap" equipment (expensive for me, and proprietary) but I have seen a couple forums talking about using srsLTE and openLTE with it. I hope the FCC entertains more things like CBRS since I'm sure a significant portion of younger hams are into SDR.
Hey, do you know anything about the amps Network? I’m trying to re-create it And a the lime sdr is hard to find I was hoping to use a cheaper alternative, but couldn’t get any definitive information if it would work, also does this GSM stuff work for really old phones? Say the iPhone 2g Or Nokia 5190
Other then a quick Google search on it just now I hadn’t heard of it. I’ll look into it more though, haven’t seen any mention of projects using lime + that. So the gsm thing should work on gsm compatible phones old/new so long as there’s a sim and proper setup with frequencies etc.
@@cemaxecuter7783 how do you talk to the cellphone once you have a device and software setup? Do you change anything on the phone such as the SIM card or something?
In this case I set the phone to gsm mode and selected the network manually most likely at some point before this video. I have a normal plain ole SIM card in it that was laying around. If you connect to phones to the same network you’d just call the other number of the 2nd registered phone.

Check out the full length and see if it fills in the gaps. Short run down here is the SDR/software create the network while the android phone is what connected to it. The texts and calls are coming from the software running the BTS/network which is optional to turn on or off. The screaming piece was a default “monkeys” audio file provided with the asterisk phone system setup.
I just realized this comment is on the full length video. Sorry about that. In this case the phone calls are being made by osmo-nitb and asterisk itself. If I had another phone on the network I could call or text from one to another.

My use case is just educational, most likely without a license you would not be able to operate this outside a shielded environment. At least not where I’m at.
Does it give me free interbet tho 😅😅😅
