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.

Yettel Bulgaria and CETIN Bulgaria have signed a 10-year power purchasing agreement for the supply of electricity from renewable sources with Elektrohold. The electricity will be provided by a 123MW photovoltaic plant, due to be completed in the spring of 2023. The overall management of the purchase and realization of the supply will be carried out by the leading trader Elektrohold Trade. The company is part of the Electrohold Group, owned by the largest public holding in Bulgaria – Eurohold.

CETIN Czechia offers from April 2023 a new tariff that brings even faster connections to users of fiber connections. The newly introduced 2000/1000Mbps tariff allows downloads and uploads at twice the speed of the former tariffs. It was designed especially for customers who work intensively with cloud applications and need to transfer large volumes of data with the highest available speeds.

CETIN continues to cover Czechia with the fastest 5G network. In mid-June this year, the company successfully completed the upgrade of its entire mobile network in the region of Central Moravia. This includes 814 base stations where the top-rated 5G network is now available, including an increase in overall network capacity. CETIN will soon upgrade another 1,000 transmitters in Moravia.

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 Czechia is running two pilot projects installing photovoltaic panels on towers in the suburban area of Prague and in a rural area in Usti nad Labem to test the grid energy savings potential and operational issues of dual powering the mobile network.

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.
