Is expanding uninterrupted 5G coverage across international transport corridors a worthwhile infrastructure priority?
Infrastructure development for the 5G-BALTICS project is underway along the 663-kilometer Via Baltica corridor, with construction beginning in August 2026. This European Union-supported initiative is actively deploying fiber-optic networks and communication masts across Estonia, Latvia, and Lithuania.
Why it matters
The project aims to unify cross-border digital infrastructure and improve network reliability along this major transit route. It addresses long-standing connectivity gaps between the Baltic states to prepare the corridor for advanced digital services.
The deployment spans a 663-kilometer route requiring extensive fiber-optic backhaul and new mast installations. Tet is responsible for 180 kilometers of this infrastructure in Latvia, utilizing site-specific engineering to ensure power delivery and signal stability.
The players
Tet
A Latvian technology and telecommunications firm specializing in fiber-optic infrastructure, data centers, and digital service integration.
Connecting Europe Facility
An European Union funding instrument that invests in trans-European networks for transport, energy, and digital infrastructure.
The details
The rollout utilizes high-capacity fiber-optic cables and custom-designed communication masts to support 5G frequencies across disparate terrain. Mast construction includes dedicated electrical grounding and power connections necessary for high-density 5G radio equipment. The work is segmented into five distinct zones to account for local environmental conditions and regulatory requirements across the three participating Baltic nations.
Timeline
August 2026: Tet began building the fiber-optic network in Latvia.
2027: Practical testing of the 5G network is scheduled to commence.
The Tech Race
The 5G-BALTICS project aligns with broader European Union initiatives to establish high-speed connectivity corridors on major transportation arteries. It represents a systematic effort to move beyond localized urban networks toward continuous, high-reliability mobile coverage across international borders.
Once operational in 2027, the network will enable continuous high-speed data access for transit operators and commercial vehicles traveling the Via Baltica. These improvements will specifically enhance real-time telemetry, automated logistics tracking, and reliable communication for fleets moving between Tallinn and the Polish border.
The takeaway
The project serves as a test case for integrating high-bandwidth 5G across international transport corridors using unified fiber-optic backhaul. Stakeholders should monitor the 2027 field test results to evaluate if the deployment meets latency requirements for autonomous vehicle support.
What happens next
Practical network testing is scheduled to begin in 2027.
