FS Italiane, TIM Enable 4G coverage in Milan-Bologna Tunnels


The FS Italiane Group and TIM have activated the first mobile radio coverage system with 4G technology in the tunnels of the Milan-Bologna Italian high-speed line, achieving complete coverage of the route.

Significant step forward within the agreement to develop connectivity on board trains and in stations

The project, which was also joined by iliad, Vodafone e WINDTRE, envisages the expansion of mobile radio coverage in all tunnels along the high-speed Turin-Naples line and from Bologna to Venice

4G technology provides passengers with a stable, high-quality connection even in the most unfavorable areas such as railway tunnels, through both the on-board WiFi service and direct coverage provided by all the TLC Operators participating in the project: TIM as the project leader, iliad, Vodafone and WINDTRE.

Upgrades to 4G technology will also be launched in the coming months on the high-speed lines between Bologna and Florence, and will continue during 2023 from Turin to Milan, from Florence to Naples and from Bologna to Venice. The aim is to achieve increasingly reliable voice and data connectivity on high-speed lines and on conventional lines, starting with the busiest routes, in order to guarantee a high-quality service to passengers on high-speed, Intercity and Regional trains and to railway companies in the freight sector.

The activation of the systems on the Milan-Bologna HS line represents the first step in the agreement signed between the FS Italiane Group, through the infrastructure manager RFI, and TIM in December 2021. Moreover, as part of initiatives linked to the NRRP, feasibility studies on the possible use of 5G technologies will be carried out.
