SmartSpires, a €3.1 million initiative co-funded by the EU’s Connecting Europe Facility (CEF), aims to turn Luxembourg’s Belval campus into a smart city living lab.

Led by a public-private consortium, including 5SKYE, Gcore, the Luxembourg Institute of Science and Technology, and Orange Luxembourg, the three-year project will demonstrate digital infrastructure and AI to power safer and more efficient urban services.

The project was presented at a press conference on 4 June 2025 at the Maison de l’Innovation in Belval, attended by Elisabeth Margue, Minister Delegate to the Luxembourg Prime Minister for Media and Connectivity.

SmartSpires aims to combine densified 5G connectivity with edge computing infrastructure to enable AI-driven and IoT-based services in ultra low-latency environments.

The project will deploy at least three smart towers, each equipped with 5G for advanced connectivity, computing for local AI and edge applications, IoT sensors, and various local add-ons to support innovative use-cases in the campus. These towers will form the backbone for real-time and data-intensive applications to enhance urban management and services. The project aims to offer a scalable model for European cities seeking to integrate advanced 5G, edge computing, and IoT solutions

The project are developing four smart city use cases, currently being specified in collaboration with local stakeholders. This includes Fonds Belval and Agora. They are two partners with whom discussions are underway regarding infrastructure deployment, with plans to extend engagement to the relevant communes to ensure alignment with local needs and priorities. Vertical stakeholders are also involved and contributing to the definition of the use cases.

A Smart City Living Lab, operated by LIST, will serve as an experimentation platform for testing and scaling new 5G-enabled urban solutions.

Three additional use-cases are targeted to directly exploit the smart towers. Mobility services will leverage 5G and edge computing to improve public transportation and traffic management. Crowd analytics will enhance public safety and urban planning by analysing the real-time flow of people and traffic. Waste management will leverage IoT sensors and local processing to optimise collection and recycling processes.

Developing these applications will involve engaging stakeholders including the general public, start-ups, and researchers.

“The launch of SmartSpires is a significant milestone in Luxembourg’s digital transformation journey. This initiative transforms Belval into a living laboratory for the smart cities of the future by integrating cutting-edge 5G connectivity, peripheral computing, and AI. While the project involves testing technologies, its true purpose is more about improving lives, enhancing sustainability, and shaping how cities across Europe can evolve in a more intelligent and responsive way. I am thrilled that Luxembourg is at the forefront of this digital innovation, thanks to the EU’s support and the strong public-private collaboration,” said Elisabeth Margue, Luxembourg Minister Delegate to the Prime Minister for Media and Connectivity.

The SmartSpires consortium brings together four key players: 5SKYE deploys and maintains multifunctional smart infrastructure that acts as a neutral host, integrating densified 5G, mini edge compute capability, digital signage and AI-based CCTV analytics; Gcore, as Project Coordinator, coordinates the project and leads edge infrastructure deployment; LIST, as Technical Coordinator, coordinates the technical design, operationalisation and evaluation of the use cases, and oversees the Belval Living Lab; and Orange Luxembourg provides the 5G network backbone.
