This article explores how 6G wireless infrastructures are enabling real-world artificial intelligence by integrating distributed sensing with physical environments, fulfilling Nikola Tesla’s century-old vision of the Earth as a giant brain. Researchers are developing multi-modal systems that use high-frequency radios as sensors to perform tasks like traffic safety monitoring and medical emergency detection, supported by 3D digital twins for safe simulation. Key technical challenges include scaling these networks to millions of autonomous devices, collecting representative real-world data, and improving energy efficiency through low-voltage matrix multiplication methods for deep learning. The work is being advanced at the University of Oulu’s 6G Flagship, which combines spatial AI, computer vision, and robust experimental infrastructure to create self-sufficient, coordinated intelligent systems.
