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!

How i can i utilize it to create 3 base station network using the just single channel. Is it possibly?

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.

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.
