Naples Metro Line 1: 4G and 5G are active along the entire route.

Tuesday June 30 2026 Naples takes a decisive step toward the digitalization of public transport. Starting today, the entire city Subway line 1 has coverage 4G and 5G, both in the 16 stations and along all the tunnels along the route from Centro Direzionale to Piscinola. This project solves a long-standing problem for commuters: making calls and surfing the internet even at depths of tens of meters, without the hassle of signal dropping out when entering the subway.

Official lighting at Municipio station

The activation of connectivity was celebrated on the morning of Tuesday 30 June with a live video call from the Municipio station, in the presence of the Councillor for Digital Transition and Smart City of the Municipality of Naples, Valerio Di Pietro, who made the first call to the director of operations of the ANM metropolitan lines, Vincenzo OrazzoImmediately afterward, the conference "Connected to the Future" was held at Palazzo San Giacomo with the project's key stakeholders. The event was promoted by the European tower company Cellnex, with the patronage of the Municipality of Naples and in collaboration with ANM, and was organized by the Key4Biz newspaper. The choice of location is not accidental: the Municipio station is one of the deepest in the network, with its platforms extending approximately 40 meters below street levelEnsuring a stable signal at that depth represents a significant technical challenge, as underlined by Francesco Favo, general manager and CEO of ANM.

Cellnex DAS technology for in-depth coverage

The project was created by Cellnex Italy through solutions DAS (Distributed Antenna Systems), a technology that distributes radio signals through a network of microantennas positioned along tunnels and in stations. This approach overcomes the challenges associated with the geological conformation of the Neapolitan subsoil and the considerable depth of Line 1, which in some places exceeds 40 meters. DAS technology has the advantage of being neutral and shared, allowing multiple operators to use the same infrastructure without having to install separate repeaters for each. Cellnex has provided additional infrastructure capacity specifically to accommodate multiple mobile operators, optimizing investments and accelerating the deployment of services. The result is a stable and high-performance connectivity which guarantees uninterrupted browsing, phone calls, and video calls, both on the platform and on board moving trains. The stated goal, as explained by Councilor Edoardo Cosenza, is to extend coverage to Line 6 in the near future, thus completing the digitalization of the city's two most important metro lines.

Line 1 numbers: 44,5 million passengers

4G and 5G connectivity arrives on a line that is recording record numbers. In the latest consolidated financial statements, the Line 1 has exceeded 44,5 million passengers, with a growth of 23% per year recorded in the first months of 2026 compared to the previous year. Even more impressive is the figure for Line 6, which recorded a 90% increase. These numbers reveal a profound change in Neapolitans' mobility habits, increasingly oriented towards public transport. According to the Transport Councillor Edoardo Cosenza, stable connectivity has implications that go beyond the simple comfort of passengers: it also affects safety, allowing always-on communications in case of emergency, and prepares the city for the appointment with the America's Cup, an event that will bring visitors from all over the world to Naples. The mayor Gaetano Manfredi He emphasized that the investment is part of an overall vision of an increasingly innovative city, where digital and transportation infrastructures go hand in hand. The project, added Federico Protto, President and CEO of Cellnex Italia, represents a virtuous model of public-private collaboration, capable of bringing concrete benefits to the community.

Practical information and future prospects

4G and 5G coverage is already active on all 16 stations on Line 1 From Centro Direzionale to Piscinola and its tunnels. For those who regularly travel on the Neapolitan metro, the difference is immediately noticeable: no more dropped calls upon entering the station or stuck navigation in the tunnels. The service works with all mobile operators thanks to the shared infrastructure created by Cellnex. For those who want to learn more, the previous article from 2024, which described the activation of Wi-Fi and 5G in the first seven stations of the line, documents the process that led to this result. The complete guide to Metro Line 1, including history, schedules, fares, and stops, remains the reference point for navigating the network. With the promise of extending connectivity to Line 6 and other public areas of the city, Naples is poised to become a model smart city where technological innovation isn't confined to laboratories, but translates into daily services for citizens and tourists.
