srsRAN 4G is an open-source software radio suite implementing a full 4G LTE protocol stack in C++, including srsUE (UE), srsENB (eNodeB), and srsEPC (core network) applications that run on general-purpose hardware with SDR peripherals. It is the legacy 4G-focused predecessor to the srsRAN Project/OCUDU 5G RAN effort.

Use cases

• build a private LTE network with SDR hardware
• simulate a 4G UE or eNodeB for wireless research
• run a lightweight 4G core network (MME, HSS, SPGW) on Linux
• prototype and test LTE protocol implementations
• capture and analyze LTE radio signals for security research
• set up an end-to-end LTE testbed on a budget

When to choose

• you need a full-stack open-source 4G/LTE implementation for research or private networks
• you want to run UE, eNodeB, and EPC on commodity hardware with SDRs
• you are studying LTE protocol internals or doing wireless security research

When to avoid

• you need 5G NR support - use the srsRAN Project/OCUDU instead
• you need a production carrier-grade RAN with commercial support
• you require a permissive license - this is AGPL-3.0
