gsm gnuradio cellular-network private-network

I Want to build a private GSM Network using OPENBTS and Gnu Radio and HACKRF?Is it possible to build one?

I would like to know is it possible and if it is then how can it be done .Any materials sources to get started with for help?

Solution

Your first problem is the hackrf is only half duplex, GSM requires full duplex operation. So you would need two hackrf's. Easier just to get one USRP.
