As a leader in wireless technology, the Singapore University of Technology and Design (SUTD), together with its industry and academia partners, has unveiled seven cutting-edge demonstrations at MWC Barcelona 2025 (3 to 6 March). These innovations showcase artificial intelligence (AI)-driven 5G networks, energy-efficient telecommunications, and next-generation Open Radio Access Network (O-RAN) solutions.
Revolutionising 5G with Artificial Intelligence (AI) and Digital Twins
1. AI-Driven Spectrum Sensing for Dynamic & Privacy-Preserving AI Model Partitioning over 5G Network
Together with Keysight, LiteON, and NeuroRAN, SUTD has developed an intelligent spectrum sensing system using the NVIDIA Aerial 5G Stack. The AI-driven spectrum sensing enables adaptive AI-driven ML model partitioning for privacy-focused image processing over 5G networks, addressing the inefficiencies of fixed model partitioning in dynamic wireless environments.
