Behind telecom towers, a strategic question of sovereignty

The announcement of the acquisition of Infracos by Phoenix Tower International (PTI) marks a structuring turning point for French telecoms infrastructures. This joint venture, previously owned by Bouygues Telecom And SFRoperates approximately 3,700 radio sites located mainly in moderately dense areas. Their shift under the control of an American actor raises the question of whether who owns, controls and arbitrates critical digital infrastructures in France?

A logical consolidation, but with political implications

From an industrial point of view, the operation is coherent, telecom towers have become an asset class in their own right, capital intensive, low risk, generating recurring income indexed to long contracts. By integrating Infracos, PTI brings its French portfolio to nearly 10,000 sitesand to more than 33,000 rounds globally, distributed between Europe, the United States, Latin America and the Caribbean.

This operation is part of a global trend, telecom operators are gradually withdrawing from holding passive assets to refocus on services, customer relations and uses. The infrastructures are sold to specialized companies, often supported by international funds.

But this economic rationality comes into tension with another issue, less immediately visible, network sovereignty.

Towers, a blind spot for digital sovereignty

Debates about digital sovereignty typically focus on cloud, data, semiconductors, or AI. Telecom towers wrongly remain in the background, yet they constitute the physical base mobile networks: without them, no 4G, no 5G, no territorial coverage.

In moderately dense areas, precisely those covered by Infracos, these infrastructures are strategic. They condition territorial planning, access to digital public services, local economic continuity and, in the event of a crisis, the resilience of communications.

The fact that these assets are now held by a foreign company does not automatically imply an immediate loss of operational control. Operators remain tenants of the sites, frequencies remain regulated, and ARCEP retains its prerogatives. But the wealth and investment decision chain moves.

International capital, extra-European interests

PTI is supported by funds managed by Blackstone, BlackRock, Wren HouseGrain and USS. Powerful institutional investors, but whose priorities are above all financial performance and capital optimization on a global scale.

In a context of geopolitical fragmentation, tensions over critical infrastructure and the rise of economic security doctrines, this internationalization poses a simple question: Do France and, more broadly, Europe, accept in the long term that key elements of their digital infrastructure are arbitrated outside their political perimeter?

Sovereignty is not a contractual clause

Even if the State retains normative and regulatory levers, by ceding control of infrastructure, it de facto abandons the capacity for arbitration. Arbitrating between investment and profitability, between territorial coverage and financial optimization, between public priorities and private constraints is no longer a sovereign decision, but a permanent negotiation. In situations of tension, crisis, operational emergency, imperative for resilience, this transfer raises questions. Sovereignty is not measured by the quantity of rules available, but by the ability to arbitrate, quickly and without an intermediary.

Towards a European doctrine of passive infrastructures?

If the operation carried out by PTI is neither illegitimate nor isolated, it above all reveals the absence of a clear doctrine on passive telecoms infrastructures in Europe. At a time when the EU is increasing initiatives on semiconductors, the sovereign cloud or defense, telecom towers remain a strategic blind spot.

The question is not to block foreign investments, but to define to what extent heritage outsourcing is compatible with the objectives of sovereignty, resilience and territorial planning. Otherwise, digital sovereignty risks remaining a software concept, disconnected from its physical reality.

The battle for sovereignty is not only being played out in data centers and AI models, but also, very concretely, at the foot of the pylons.
