Italy Pauses RAN-Sharing Deal on Competition Concerns

Why It Matters

The inquiry threatens to curb a major efficiency‑driven consolidation that could accelerate 5G deployment, while preserving competition and spectrum‑auction integrity in a market already dominated by a few players.

Key Takeaways

• AGCM opened probe into TIM, Fastweb, Vodafone RAN-sharing plan.
• Combined wholesale market share exceeds 80% in towns under 35k.
• Joint retail share surpasses 55%, over 70% in business segment.
• Spectrum holdings represent over 60% of local mobile frequencies.
• Investigation may stall 5G rollout and curb operator investment.

Pulse Analysis

Radio‑access‑network sharing has become a cornerstone of European 5G strategies, allowing operators to split the massive capital outlay required for dense antenna deployments. In Italy, the TIM‑Fastweb‑Vodafone consortium aimed to pool passive and active infrastructure, as well as spectrum, under a Multi‑Operator Core Network (MOCN) framework. Such arrangements can lower costs, speed up coverage expansion, and improve service quality, especially in low‑density municipalities where individual rollouts are less economical. However, the benefits hinge on maintaining competitive pressure, which regulators closely monitor.

The AGCM’s investigation zeroes in on market concentration and spectrum control. By combining more than 580 MHz of frequencies—over 60% of the local allocation—the trio could diminish incentives to compete for future auctions, potentially leading to coordinated pricing or reduced investment in network upgrades. The watchdog also worries that shared RAN planning, a key competitive lever, might erode the distinctiveness of each carrier’s service offerings. While WindTre and Iliad already share infrastructure via MOCN, the TIM‑Fastweb‑Vodafone pact would dominate wholesale access, raising the stakes for antitrust scrutiny.

If the probe extends beyond the 60‑day response window, the three operators may face a prolonged hold‑up, delaying the anticipated efficiencies and slowing Italy’s 5G penetration. Investors will watch for any regulatory concessions that could reshape the deal’s scope or force divestitures. Conversely, a green light after thorough review could set a precedent for larger‑scale sharing models across Europe, balancing cost savings with competition safeguards. The outcome will signal how aggressively Italian authorities will protect market dynamics while still encouraging the rapid rollout of next‑generation mobile services.
