MTS has completed the main phase of modernizing its mobile communications network, delivering full coverage across all lines of the Moscow metro. The upgrade is part of a broader digital ecosystem initiative, with technicians installing radiant cables throughout tunnels and upgrading equipment to boost reliability and speed.
By the end of 2023, the radiating cable network had grown to nearly 200 kilometers and roughly 700 additional base station units were deployed. These enhancements ensured uninterrupted mobile service on every metro line and station, including newly opened stops, enabling riders to stay connected as they travel from one end of the city to the other. This expansion marks a significant step toward a seamless, city-wide communications network for metro passengers. Source attribution follows company communications about the project.
Industry data highlights the impact of the upgrade: about 2.8 million subscribers use mobile internet in the Moscow metro every day. The metro’s internet traffic demonstrates a growth trajectory that outpaces overall Moscow usage, with the most heavily loaded base stations located within the metro system. These figures illustrate how the metro is becoming a major conduit for mobile data consumption in the capital. The project underscores MTS’s role in supporting high-density urban mobility and digital life in Moscow.
In December alone, subscribers downloaded around 1,100 terabytes of data weekly while riding the metro, a volume that surpasses the data traffic of some other large Russian cities. The acceleration in data flow reflects both increased user demand and the metro’s ongoing expansion, which continues to drive elevated usage levels among daily commuters and visitors alike. This trend reinforces the need for robust, high-capacity infrastructure in metropolitan transit corridors.
Engineers also achieved a unification of all LTE frequency bands, which raised peak mobile internet speeds to as much as 500 megabits per second at metro stations and 250 megabits per second inside tunnels. The reconfiguration not only boosts speed but also enhances reliability and session stability for streaming, navigation, and real-time updates during travel. The improvements are positioned to support growing demand from passengers and the evolving metro experience. Source attribution follows company communications about the project.
Looking ahead, project leaders expect traffic to continue rising in step with both consumer internet use and ongoing metro developments. The expansion plan calls for bringing communications to new Troitskaya Line stations and optimizing existing network segments that require non-standard technical solutions. These goals reflect a forward-looking strategy to maintain high performance as the metro grows and passenger patterns shift over time.

VoLTE usage also surged in 2023, with voice traffic over the LTE network increasing by almost six tenths compared with the previous period. This growth indicates improved voice quality and reliability for metro users, further underscoring the value of integrated data and voice services in a dense urban transit environment.

Historically, the metro network has been a proving ground for service quality and network resilience. MTS has reinforced the claim to leadership in mobile internet quality within Moscow’s transit corridor, ensuring that passengers experience consistent performance whether they are commuting, working on the go, or simply staying connected while moving between stations. The transition from earlier arrangements to a unified, modernized network reflects a deliberate shift toward a more reliable and scalable mobile ecosystem for urban mobility.
