Note: As this space develops so quickly I’ve refreshed the original post from November 2021 in March 2021 with updated instructions. While 5G SA devices are still in their early stages, and 5G RAN hardware / gNodeBs are hard to come by, so today we’ll cover using UERANSIM to simulate UEs and 5G RAN, to … Continue reading My first 5G Core: Open5Gs and UERANSIM
