LibreCellular 5G

Open hardware SDR-based 5G cellular network

The LibreCellular 5G project makes it easier to create 5G cellular networks with open source software and low cost software-defined radio (SDR) hardware. Achieving this via validated configurations that are subjected to rigorous end-to-end testing, supported by tooling and documentation for repeatable deployment. This work builds on previous NLnet funded projects which made it easier to create 4G cellular networks, by adding support for a 5G New Radio (NR) base station, together with 5G Core (5GC) network functions, native voice calls via Voice-over-New Radio (VoNR), and implementing a Python library for base station control.
