Abstract

The convergence of 5G and IoT enables fully connected, intelligent environments, but it faces challenges from the fragmentation of public/private 5G networks and the heterogeneity of IoT networks. We propose a unified framework using CAMARA open gateways, which provide standardized, open APIs to expose network capabilities, reducing fragmentation and simplifying interoperability, supported by a federated SDN architecture that ensures scalable cross-domain control. We further demonstrate 5G-based remote control of KNX devices, extending industrial and building automation. These contributions lay the foundation for a secure, dynamic "network of networks" supporting next-generation applications.
