  • Open Gateway: GSMA CAMARA Project APIs via NEF integration for direct 5G core access
  • Intelligent Control: xApps and rApps on RICs for real-time resource optimization
  • Analytics: NWDAF (Network Data Analytics Function) for predictive optimization
  • MLOps: MLflow/KubeFlow infrastructure for ML lifecycle automation

Application Technologies

  • N3IWF: Non-3GPP interconnection for medical devices (BLE, Wi-Fi) into 5G core
  • Medical Devices: Portable cardiac ultrasound, pulse oximeter, Polar H10 ECG belt
  • Dashboards: React Native/ReactJS/NodeJS for real-time patient information visualization
  • XR Platform: Meta Glasses API, Unity, WebRTC/LiveKit streaming pipelines
  • Security: STRIDE, LINDDUN, DREAD threat modeling frameworks

Scientific Differentiators

  1. NWDAF predictive analytics for dynamic resource optimization using near-real-time traffic and application behavior data
  2. N3IWF cross-network connectivity for secure interconnection of medical devices on untrusted networks with the 5G infrastructure
  3. Open Gateway / NEF API integration exposing network capabilities via standardized open APIs for programmable health applications
  4. Distributed intelligence via RICs with adaptive slicing integrating Non-RT and Near-RT controllers with dedicated rApps and xApps
  5. Multi-institution distributed testbed connecting UNISINOS, UFRGS, PUCRS, and UFCSPA via Metropoa metropolitan network
