ALIX is a 5G TN/NTN system-level simulator that is used for detailed protocol level simulations for 5G NTN and TN.
Operating on a packet level resolution, ALIX makes it possible to evaluate technology performance, support 3GPP 5G NTN standardization efforts, and research future technologies such as 5G-Advanced and 6G NTN.
Evaluate technology performance and differences
