In January 2024, CETIN Bulgaria launched the EU co-funded 5G Balkans project1 to strengthen fibre optic infrastructure along the Sofia–Dimitrovgrad corridor, part of the TEN-T Orient/East-Med network, a key EU transport route under the Trans-European Transport Network. The project supports the future rollout of 5G-enabled Connected and Automated Mobility (CAM) services and reflects CETIN’s broader ESG ambitions.
CETIN Bulgaria advances sustainable infrastructure with the 5G Balkans project
Implemented in collaboration with CETIN Serbia, Yettel Bulgaria and Yettel Serbia, and the Technical University (TU) of Sofia, the initiative will deploy 100 km of new high-speed fibre connectivity and upgrade existing routes. TU Sofia will provide independent performance assessments and identify any signal disturbances relevant to future road safety technologies.
The project illustrates CETIN’s efforts to align infrastructure expansion with long-term sustainability goals. CAM technologies help decarbonise transport through smart logistics, traffic optimisation, and autonomous driving-reducing fuel use and emissions. Fibre optic networks also offer significant energy savings, consuming up to 12 times less power per transmitted bit compared to traditional systems.
In addition to environmental benefits, the project supports digital inclusion by extending connectivity to underserved regions and improving access to digital services. It also exemplifies effective cross-border cooperation and alignment with EU-wide digital and sustainability priorities.
