“Open” Telecom Networks (Open RAN): Towards a Reconfiguration of International Competition in 5G?
In line with the anti-Huawei diplomatic campaign of the Trump and Biden administrations, the United States has promoted an alternative: Open RAN, a concept defined by "open" network architectures. At the intersection of 5G geopolitics and standards, what risks and opportunities does Open RAN present for European technological sovereignty?
The Radio Access Network (RAN) is the radio part of a mobile telecommunications system that enables the connection between a mobile device (such as a phone or computer) and the core network. While traditionally a single vendor (such as Huawei, Ericsson, or Nokia) provides a “proprietary” or “closed” solution for this part of the network, Open RAN (Open Radio Access Network) is a concept describing disaggregated architectures that divide the RAN into several bricks connected by open interfaces. The objective is to allow the operator to buy these hardware and software bricks from various suppliers, and to choose freely the most suitable option for each part. In the current context of a concentrated 5G market, dominated by three major manufacturers and even facing the risk of an Ericsson-Nokia duopoly with the exclusion of Huawei from many countries, telecom operators emphasize the flexibility and diversification of suppliers allowed by Open RAN, which would allow both more innovation and cost reduction. In line with its diplomatic campaign against “unreliable” Chinese suppliers, the United States has actively promoted Open RAN as an alternative.
However, Open RAN seems far from being a panacea for Europe: in addition to the difficulties that remain in terms of maturity, security, performance and transparency of the specification process, it risks increasing European dependence on foreign suppliers. Although Huawei is not part of the international bodies working on Open RAN (such as the Telecom Infra Project or the O-RAN Alliance), many companies close to the Chinese political and military authorities are. Beyond the question of supplier security, American lobbying is linked to the commercial opportunity that Open RAN represents for American companies, currently leaders in the cloud, software and generic hardware components…even though they do not have a major 5G champion. Open RAN is therefore an issue at the crossroads of the geopolitics of 5G and standards, to which the European Union is beginning to provide a common political and analytical response, despite the diversity of positions among member states.

Center for Geopolitics of Technology
Artificial intelligence (AI), 5G, cybersecurity, robotics, semiconductors, space…Technologies—particularly digital technologies—now profoundly affect all human activities and, by extension, international relations. The political, strategic, economic, and social stakes that arise from them are expressed across multiple political levels, involving states, international organizations, and private companies alike. International dynamics of competition and cooperation are being reshaped as a result. To address these challenges, Ifri launched its Geopolitics of Technology Center in 2020, offering a distinctly European perspective on the international issues surrounding so-called critical technologies.

Europe at the Crossroads of DefTech: Rethinking the European Defense Innovation Ecosystem
“The way I look at Iron Dome is as the ultimate manifestation of the future of the United States’ role in future conflicts, which is not to be the world police, but to be the world gun store,” said Palmer Luckey in November 2023. Luckey is the founder of Anduril, one of the most prominent DefTech companies. The ambition is clear: to participate in global rearmament by capitalizing on the quality of American innovations and to dominate the arms market—at least in the West—through technological mastery.
How Technology Is Reshaping the World Order
The central role of technology in the competition between the major powers is fueling an ever-more intense rivalry. Artificial intelligence is enabling large corporations to accrue unprecedented power, with consequences for states and even for international conflict. However, states do have tools at their disposal to regulate these developments. In this international competition, Europe has a strong hand, but must be prepared to play its cards in order to create a new kind of international cooperation.

Regulatory Dynamics and Tensions in the Space Sector: Towards and Americanization of Space Law?
The development of space law has gradually evolved from a top-down normative dynamic dominated by the founding impetus of the UN to a bottom-up normativity driven by national and industrial practices. This evolution is now accompanied by growing normative competition, raising the risk of an Americanization of space law and prompting the question of a European response.
