DeepSig and NVIDIA's MWC 2026 demonstration showcases a 6G "AI-Native Air Interface" that replaces standard 5G modulation with an AI-learned neural autoencoder. Running on the OCUDU 5G gNB and powered by NVIDIA's DGX Spark platform, the system claims to deliver up to 2x higher edge throughput, improve spectral efficiency, and allow seamless, simultaneous 5G and 6G spectrum sharing to bridge the transition to next-generation networks.
