The srsRAN suite includes:
* srsUE - a full-stack SDR 4G/5G-NSA UE application (5G-SA coming soon)
* srsENB - a full-stack SDR 4G eNodeB application (5G-NSA and 5G-SA coming soon)
* srsENB - a full-stack SDR 4G/5G-NSA eNodeB application (5G-SA coming soon)
* srsEPC - a light-weight 4G core network implementation with MME, HSS and S/P-GW
