The independent network infrastructure operator CETIN Bulgaria has finished the installation of photovoltaic systems on its data centers (DC) in Sofia and Plovdiv. A system with an expected annual yield of 178.5MWh has been added to the roof of Serdika DC, and a 47.617MWh system now helps power Trakia DC in Plovdiv.

High-speed connectivity in rural areas is a necessary pre­condition for attracting the working-age population to live in smaller towns and villages. CETIN Czechia is a champion in rural cove­rage, with its fixed Next Generation Access (NGA) network available for more than 63% of all Czech rural households (Digital Econo­my and Society Index DESI, 2021). Most of the rural coverage is built using a fiber-to-the-cabinet (FTTC) network, which enables the users to achieve speeds of up to 250Mbps. However, since 2019, CETIN’s main focus has been the deployment of state-of-the-art fiber-to-the-home (FTTH) networks, including in rural areas.

CETIN Group operating units have multi-operator radio access network sharing agreements in Czechia and Hungary. That means that mobile networks built and operated by CETIN Group subsidiaries are being used to deliver communication services to the end customers of more than one commercial operator.

The SD-WAN networking strategy allows companies to replace outdated firewalls, routers, and WAN optimization appliances with a single appliance. This minimizes hardware requirements and power consumption. In addition, the entire strategy is sustainable and has a high-security profile. The project will be completed later this year.
