The Italian telecommunications market has always been one of the most competitive in Europe. As we navigate through 2026, the pressure to provide nationwide 5G coverage while maintaining profitability has reached a boiling point. High spectrum auction costs, complex geography, and energy price volatility have forced Italian giants like TIM, Vodafone, WindTre, and Iliad to rethink their business models.

At tech.mobilesathi.com, we are closely monitoring a global shift toward "Co-opetition"—where rival companies cooperate on infrastructure to compete on services. In Italy, this has manifested as massive Network Sharing agreements. This 2500-word report explores how these deals are saving billions in CAPEX and what they mean for the future of 5G-Advanced and 6G.

Network Sharing in Italy: How Operators are Managing 5G Costs in 2026

Large bold text across the bottom reads: "ITALIAN OPERATORS: 5G NETWORK SHARING FOR COST MANAGEMENT". The background features digital data streams and a Euro currency symbol implying financial strategy.

Major Italian operators—TIM, Vodafone, WindTre, and Iliad—are increasingly adopting infrastructure sharing models to reduce the high capital expenditures (CAPEX) associated with nationwide 5G rollout.

1. The Economic Burden of 5G in Italy

Italy’s 5G journey started with one of the most expensive spectrum auctions in history, raising over €6.5 billion for the government. This massive upfront cost left operators with limited budgets for the actual rollout of physical towers and fiber backhaul. Additionally, Italy's strict electromagnetic field (EMF) limits and mountainous terrain make tower placement difficult and expensive.

To avoid financial collapse while meeting the European "Gigabit Society" goals, operators realized that building four separate, parallel 5G networks was economically impossible. Network sharing became the only logical escape route.

2. Understanding Network Sharing: Passive vs. Active

Before analyzing the deals, it is important to distinguish between the two types of sharing currently used by Italian operators:

Passive Sharing: Operators share physical sites, towers, power supplies, and cooling systems. This is the most common form and is managed by "TowerCos" like INWIT.
Active Sharing (MORAN/MOCN): Operators share the actual radio equipment (antennas) and sometimes the spectrum itself. This offers much higher cost savings but requires deep technical integration.

3. Major Italian Alliances: TIM, Vodafone, and INWIT

The most significant passive sharing deal in Italy is centered around INWIT. Originally a subsidiary of TIM, it merged with Vodafone Italy’s tower assets to create the largest tower company in Italy. By sharing over 22,000 towers, TIM and Vodafone have significantly reduced their maintenance costs (OPEX) and accelerated their 5G footprint in urban centers.

4. The WindTre and Fastweb 5G Partnership

In a bold move toward active sharing, WindTre and Fastweb signed a 10-year agreement to co-invest in a nationwide 5G network. Under this deal, WindTre provides access to its vast network of physical sites, while Fastweb provides the high-capacity fiber backhaul. This "Fiber-meets-Radio" strategy has allowed both companies to claim 5G coverage parity with the market leaders at a fraction of the cost.

5. Zefiro Net: The Iliad and WindTre Joint Venture

Recognizing the difficulty of covering rural Italy, Iliad and WindTre formed a joint venture called Zefiro Net. This entity owns and manages the network in less populated areas (covering about 26% of the Italian population). By sharing the costs of maintaining these remote towers, both operators can fulfill their regulatory coverage requirements without bleeding cash in low-revenue regions.

6. Managing Costs: CAPEX and OPEX Savings Analyzed

Data from 2025-2026 suggests that network sharing in Italy has led to:

CAPEX Savings: A reduction of 25% to 35% in new infrastructure spending.
OPEX Savings: Energy and site rental costs have dropped by 20% due to shared hardware and consolidated site management.

These savings are being redirected into 5G-Advanced (5.5G) research and customer acquisition strategies.

7. Impact on Service Quality and Consumer Pricing

Does sharing mean slower speeds? Not necessarily. While the "pipe" is shared, the logic of the network (Core) remains separate. This allows operators to differentiate their services. For consumers, network sharing has prevented the aggressive price hikes seen in other sectors, as operators are able to absorb inflation through infrastructure savings.

8. Regulatory Hurdles: AGCOM and European Union Oversight

The Italian regulator AGCOM and the EU competition authorities monitor these deals closely to ensure they don't lead to a "monopoly by stealth." The main concern is that if every operator uses the same towers and antennas, there is less incentive to innovate on network quality. So far, the regulators have approved these deals provided that the "Core" networks remain independent.

9. The Road to 6G: Is Sharing the Only Way Forward?

As the industry looks toward 6G in 2030, the Italian model is being studied globally. With 6G requiring even higher tower density (small cells), the cost of going solo will be astronomical. Network sharing is no longer a temporary fix; it is the permanent blueprint for the future of telecommunications.

10. Final Verdict: A Sustainable Model for Global Telecoms?

The Italian experience proves that network sharing is the most effective tool for managing the transition to high-frequency 5G and 6G. By sharing the "dumb" infrastructure (towers and steel), operators can focus on the "smart" side (AI, cloud services, and customer experience). At tech.mobilesathi.com, we believe this model is essential for markets like India, where BSNL and private players face similar geographic and financial hurdles.

11. Frequently Asked Questions (FAQs)

Q: Does network sharing cause more call drops?
No. In fact, it often improves reliability because operators can use each other's towers to fill signal gaps.

Q: Is Iliad part of any sharing deal?
Yes, Iliad shares towers with WindTre in rural Italy through the Zefiro Net joint venture.

Q: Will 5G prices increase in Italy due to these deals?
Actually, these deals help keep prices stable by reducing the huge costs operators would otherwise pass on to customers.
