DragonOS Focal Running a GSM network in minutes (osmo-bts, osmo-bsc, osmo-bts-trx, USRP b205mini-i)
How to setup a GSM network using DragonOS Focal built-in tools and a USRP b205mini-i. There’s also the possibility of running the network with a LimeSDR, but I have not tested it. The steps would be slightly different.
I used an Android S4 for the video that had an old SIM card in it already. Adding the IMSI to the HLR is important, otherwise the phone will not be able to register to the network.
