srsRAN is a free and open-source 4G and 5G software radio suite.

Featuring both UE and eNodeB/gNodeB applications, srsRAN can be used with third-party core network solutions to build complete end-to-end mobile wireless networks. For more information, see www.srsran.com.

The srsRAN suite currently includes:

  • srsUE: a full-stack 4G and 5G NSA UE application (5G SA coming 2022)

  • srsENB: a full-stack 4G eNodeB and 5G NSA gNodeB application

  • srsGNB: a full-stack 5G SA gNodeB application (coming 2022)

  • srsEPC: a light-weight 4G EPC implementation with MME, HSS and S/P-GW

All srsRAN software runs in linux with off-the-shelf compute and radio hardware.
