Technological environment

Luxembourg provides an ideal technological environment for innovation leaders and growing businesses. Built on security and reliability as its pillars and renowned for its superb connectivity, the Grand-Duchy displays a state-of-the-art and ever-evolving digital infrastructure. Discover different parts of the nation's digital backbone and how they help national and international partners thrive.

A model pupil in the EU's digital frontier and ICT infrastructure

Ranked among the EU's top performers in digital infrastructure according to the Report on the state of the Digital Decade, Luxembourg stands as a valuable contributor to the EU's Digital Decade targets. Through constant expansion and upgrades of its broadband infrastructure, coupled with a powerful high-performance computing (HPC) ecosystem and excellent 5G coverage, the Grand Duchy shows its dedication to strive for innovation.

In fact, the proper functioning of businesses nowadays heavily relies on information and communication technologies (ICT). As a result, well-developed networking can have a huge impact on success and growth. Backed by cutting-edge digital infrastructure, Luxembourg's ICT sector unites Luxembourg's key ICT players to cultivate cross-sectoral opportunities, facilitate business growth, and foster collaboration between companies and research institutions.

Powerful, together: Luxembourg's HPCs

Meet Luxembourg's most capable supercomputer: MeluXina. At its launch in 2021 under the European High Performance Computing Joint Undertaking (EuroHPC JU), where it earned a place among the top 50 supercomputers worldwide, it was named after Melusina, the mythic mermaid from one of the country's founding legends. A suitable name, considering MeluXina is water-cooled and serves as a cornerstone in the national digital ecosystem.

Its computing power allows both public and private companies, along with research organisations, to access a wide range of services across various domains such as climatology, engineering, aeronautics, automobile design, energy production, medicine or financial analysis. Consequently, Luxembourg introduced a master programme in high performance computing in 2023 to train the future generations of national and European HPC specialists.

Europe's densest network of next-generation data centres

Next to raw computational power, security and trust are core qualities of Luxembourg's ICT development strategy. Hence, why three of its 16 modern data centres are Tier IV certified, indicating their adherence to the highest industry standards for reliability and efficiency. This national network features the highest density of Tier IV data centres in Europe. With flexible data centre providers like, LuxConnect, ebrc or DATA4, the Grand Duchy offers a wide range of services for both ICT start-ups and multinational companies.

Connectivity: A strong link in the chain

Connectivity is a vital component for establishing a reliable ICT environment. Situated in the heart of Europe, Luxembourg is intricately connected to an international fibre network, making it an ultra-low latency hub. With a well-defined ultra-high-speed broadband strategy, its national very high-capacity network (VHCN) and 5G coverage are constantly increasing, continually outperforming the European averages.

Benefiting from widespread fibre optic infrastructure, which extends to three-quarters of households, Luxembourg ranks within the top 30% in Europe for broadband speed. Next to its active fibre network, the Grand Duchy is home to several dark fibre grids. These dormant networks serve as critical infrastructure for upgrading telecommunications and internet connectivity within the country and meeting the increasing demand for high-speed data transmission services.

Technology driving growth: national collaborators

Here are three of the many players in this intertwined digital environment:

Research Luxembourg counts many actors in the public research domain. For example, the Luxembourg Institute of Health (LIH), the Luxembourg Institute of Science and Technology (LIST) and the University of Luxembourg ( to name a few.

In the field of research, the national digital infrastructure facilitates data exchange whilst keeping a high level of security and privacy for sensitive research information. Furthermore, access to supercomputers such as MeluXina, AION ( or the LIST's HPC supports research projects across a variety of fields and allows them to tackle complex computation problems.

SES is one of the world's leading satellite operators, headquartered in the Grand Duchy. In collaboration with national institutions like the LIST, they utilise and build upon Luxembourg's digital infrastructure to drive innovation and shape the future of the country.


As a dedicated hub for fintech collaboration, the LHoFT leverages Luxembourg's connectivity and ICT to connect start-ups, financial institutions, and regulatory bodies. It serves as a networking steppingstone for smaller companies and aims to support their growth in the fintech ecosystem.
