5GSimWaveform is the original simulator being used to accompany the 5G Physical Layer book by Ericsson engineers (Chapter 9: Simulator) [1]. [1] 5G Physical Layer: https://www.ericsson.com/en/reports-and-papers/books/5g-physical-layer https://www.ericsson.com/en/reports-and-papers/books/5g-phys...

Wonder why they don't put it on github... I feel MUCH more comfortable browsing "open source" code on somewhere like that than I do downloading and extracting a .zip archive from a random website.

  You shouldn't. Github is a gigantic pile of javascript that has to execute on your machine. `Unzip` doesn't execute anything. If you're really paranoid, use an `unzip` tool written in Rust: https://lib.rs/keywords/zip-archive https://lib.rs/keywords/zip-archive

    No, he really should. Unzip is not the only software interacting when downloading things. A browser has way better sandboxes than the rest of the operating system and desktop environnement. For instance, here is a vulnerability from the past year leading to code execution on download: https://github.blog/2023-10-09-coordinated-disclosure-1-click-rce-on-gnome-cve-2023-43641/ https://github.blog/2023-10-09-coordinated-disclosure-1-clic...

"Download the simulator" dumps source code for a proprietary (and very expensive) tool. I see no examples on how to run this. Some of the links on the linked page 404. It's hard to take this submission seriously...

  I see a readme.txt: > Usage of 5GSimWaveform: > 1. Direct to subfolder [5GSimWaveform/ptplink] > 2. (optional) Change/select system parameters (e.g. waveform, symb rate, subcarrier #, etc.) in > <sSysParDefault.m> > 3. (optional) Switch on/off analog impairments (e.g. PN, CFO, noise, etc.) in <sAnaParDefault.m> > 4. Run <setpath.m> >5. Run <runSim.m> > " As for how to run it, seems it's MATLAB code

      Plenty of opensource projects are built on closed source tooling/dependencies. For example, opensource projects that only work on Windows. Sure, it isn't ideal, but I'd still by far have these projects open source than not.

    It's potentially using a bunch of Matlab toolboxes, being a communications related tool, but it's always worth trying to run Matlab code in GNU Octave. https://octave.org/ https://octave.org/

You can simulate a 5G base station and/or a phone (UE) with this software and have them talk to each other over your local network or localhost You can even use an SDR to create a real base station or UE (local laws allowing) at home. The tool has logging and quite nice plots that show the constellation diagrams, signal decoding, etc. https://github.com/oai-group/openairinterface5g https://github.com/oai-group/openairinterface5g
