Also see Fabrice Bellard's LTE/NR Base Station Software https://bellard.org/lte/ https://bellard.org/lte/ > LTEENB allows to build a real 4G LTE/5G NR base station (called an eNodeB (4G) or gNodeB (5G)) using a standard PC and a low cost software radio frontend. All the physical layer and protocol layer processing is done in real time inside the PC, so no dedicated hardware is necessary. NB-IoT and Cat-M1 devices are also supported. The software is now developped and distributed by Amarisoft.
