The recent ETSI IoT and M2M workshop in Sophia Antipolis focused on the digitization of smart cities, highlighting the need for an open common reference architecture to integrate diverse vertical services. Real-world implementations from cities like Bordeaux, Murcia, and Greenwich demonstrated the practical application of standards, while the event showcased oneM2M Release 2 specifications that enhance security and semantic interoperability across sectors such as energy, healthcare, and home automation. A concluding panel discussion emphasized that the future of IoT ecosystems relies on a standardized architecture to enable seamless information exchange between different solutions and business areas. These developments underscore the role of global standards initiatives in supporting advanced IoT technologies and ensuring interoperability across the expanding Internet of Things landscape.
