Open source 5G UE and RAN (gNodeB) implementation.
UERANSIM (pronounced “ju-i ræn sɪm”), is the open source state-of-the-art 5G UE and RAN (gNodeB)
simulator. UE and RAN can be considered as a 5G mobile phone and a base station in basic terms. The project can be used for
testing 5G Core Network and studying 5G System.
UERANSIM introduces the world’s first open source 5G-SA UE and gNodeB implementation.
[!IMPORTANT]
UERANSIM is no longer actively developed by the maintainer. However community contributions are welcomed.
Basic functionalities of UE and gNodeB are fully functional and ready to use. However some of the features are not complete.
More details can be found at Feature Set.
On the other hand, UERANSIM does not fully provide physical layer. 5G-NR radio interface is partially implemented, and simply simulated over UDP protocol.
You can find the documentation on UERANSIM Wiki.
And, since the project is rapidly developing, please make sure that you have always
the latest UERANSIM.
Any contributions you make are greatly appreciated via Pull Request.
