Dipl.-Ing. Dan Iordanescu

Research on possible paths for mobile network transformation with the final scope of flexible, scalable, fully autonomous and virtualized networks: - Network discovery, clean-up and performance assessment. Preparation for network migration. - Applicability of emerging virtualization technologies: NFV, SDN, SDR, MEC, centralized-RAN, cloud-RAN/vRAN - Management of IoT deployments and security - Recommendation of practical migration steps for Network Transformation.
