SUSTAINET-inNOvAte focuses on developing frictionless, secure, and resilient communication infrastructures to meet the growing demands of Europe’s digital and green transformation. The project emphasizes ultra-reliable, low-latency networks for critical sectors such as industrial production, public utilities, and healthcare. Through the integration of time-sensitive networking, digital twins, trusted AI, and neuromorphic computing, SUSTAINET-inNOvAte explores new architectures for end-to-end connectivity and real-time service delivery. A key priority lies in protecting networks through advanced detection, mitigation, and predictive maintenance strategies while ensuring energy efficiency and adherence to European data privacy standards. By addressing the full heterogeneity of future communication systems—from Wi-Fi 8 and 6G to industrial PON and edge computing—SUSTAINET-inNOvAte lays the groundwork for robust and sovereign infrastructure solutions made in Europe.
