5G-LENA Simulator

ns-3 module to simulate 3GPP 5G networks

5G-LENA is a GPLv2 New Radio (NR) network simulator, designed as a pluggable module to ns-3. Its development, initially funded by InterDigital, is open to the community in order to foster early adoption, contributions by industrial and academic partners, collaborative development and results reproducibility.

The simulator is the natural evolution of LENA, the LTE/EPC Network Simulator, the development started from the mmWave module, and it incorporates fundamental PHY-MAC NR features aligned with NR Release 15 TS 38.300. The first release of the simulator is dated February 2019.

Inherit the strengths of ns-3

ns-3 is an open source discrete-event network simulator/emulator. The ns-3 project is committed to build a solid, well documented, easy to use and debug simulation core, which caters to the needs of the entire simulation workflow, from simulation configuration to trace collection and analysis.

Compared to other open source simulators, ns-3 offers multi-RAT (Radio Access Technology) and multi-band simulation capabilities, with Wi-Fi, WiGig, LTE (LTE-A, LAA, LTE-U), among others, already openly available.

Born in academia

5G-LENA is born within the Mobile Networks group of a public research institute, CTTC (Centre Tecnològic de Telecomunicacions de Catalunya). The Mobile Networks group maintains a strong commitment with the ns-3 community in the area of LTE, its evolutions in licensed and unlicensed spectrum, and NR.

The outcome of 5G-LENA simulator through an end-to-end performance assessment is analyzed in many peer-reviewed papers, and there is plenty of material to consider for the bibliography of your next paper.

… and for industries?

We have successfully collaborated with many industries and agencies like Ubiquisys, WiFi Alliance (WFA), Spidercloud Wireless, InterDigital, National Institute of Standards and Technologies (NIST), Lawrence Livermore National Lab (LLNL), Google Summer of Code and many EU projects funded in the framework of FP7 and H2020.

For any inquiry, we have a team at your disposal for modeling, design, development, field trials, testing, 3GPP knowledge and 3GPP standard practical implementation. Why don’t you consider us for your next proposal?
