The Int5Gent approach integrates advanced technologies across the data plane, control plane, and application layers to enable high-capacity, low-latency, and flexible network solutions for demanding vertical applications in beyond 5G (B5G) networks. Focusing on edge computing, Sigma-Delta over-Fiber (SDoF), Digital Radio-over-Fiber (D-RoF), Analog Radio-over-Fiber (A-RoF), millimeter-wave (mmWave) backhaul, and GPU-enabled processing, it supports Artificial Intelligence (AI)-driven use cases such as real-time video analysis and critical communication for Public Protection and Disaster Relief (PPDR). The platform demonstrators show: a) real-time human detection and AI inference at 15 frames per second (fps), showcasing network resiliency and integration of A-RoF with D-band transceivers for high-speed video transmission and b) the system's ability to monitor critical infrastructure (railway), using edge-based processing for safety-critical applications and dynamic transport slicing for operational needs. Both demonstrators validated the platform's ability to orchestrate and optimize resources in real-time, offering scalable, resilient solutions for future 5G deployments.
