We’ve seen quite a few DIY 2G networks over the years, but the 4G field has been relatively barren. Turns out, there’s an open source suite called srsRAN that lets you use an SDR for setting up an LTE network, and recently, we’ve found a blog post from [MaFrance351] (Google Translate) that teaches you everything you could need to know if you ever wanted to launch a LTE network for your personal research purposes.
For a start, you want a reasonably powerful computer, a transmit-capable full-duplex software defined radio (SDR), suitable antennas, some programmable SIM cards, and a few other bits and pieces like SIM card programmers and LTE-capable smartphones for testing purposes. Get your hardware ready and strap in, as [MaFrance351] guides you through setting up your own base station, with extreme amounts of detail outlining anything you could get caught up on.
First, get DragonOS set up — that’ll help you avoid compiling srsRAN from scratch. Then, treat yourself to a short guide on editing srsRAN config files. Having done that, connect your SDR, and run a few commands. This is enough to have your LTE network show up in the list of available networks on your phone.
Of course, you won’t be able to connect to it yet — that’s where the SIM cards come into play. Flash them with your network’s ID and a few other parameters, add your SIM into the srsRA ..
