srsRAN 4G is an open-source 4G software radio suite from SRS. For 5G RAN, see our new O-RAN CU/DU solution - srsRAN Project.

Featuring UE, eNodeB and lightweight EPC applications, srsRAN 4G can be used to build a complete end-to-end LTE mobile wireless network. For more information, see www.srsran.com.

The srsRAN 4G suite currently includes:

  • srsUE: a full-stack 4G UE application with prototype 5G features

  • srsENB: a full-stack 4G eNodeB

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

All srsRAN 4G software runs in linux with off-the-shelf compute and radio hardware.

For our ORAN-native 5G CU/DU solution, see the srsRAN Project documentation.
