CETIN was established in the Czech Republic in 2015, when the infrastructure arm of O2 was successfully spun off into a separate company. CETIN Group’s vast networks and infrastructure require highly skilled technical supervision to guarantee the reliability and stability of its services. They comprise high-end voice and data services, including TV broadcasting services, IT services, and cyberservices.
CETIN’s mission is to build, operate, and develop a reliable, secure, and high-speed telecommunications infrastructure. This mission is an essential pillar of digitalisation and a driver of the Czech Republic’s economic competitiveness. As the owner and operator of the country’s largest electronic communications network, CETIN delivers wholesale services to all telecommunications operators and internet access providers that serve end customers through CETIN infrastructure.
In addition to providing mobile and fixed network infrastructure for households and businesses (network access services, xDSL and fibre-optic connectivity, IPTV, and voice services), CETIN delivers data solutions for corporate networks and data centre leasing. It also offers international voice services to domestic providers and more than 200 telecommunications operators worldwide.
CETIN invests billions of Czech crowns annually in the continued development of its infrastructure. In 2024, the company further expanded the reach of its FTTH fibre-optic connections, increasing the average speed available in the fixed network more than 150% to 426 Mbps. The company is accelerating the rollout, aiming to reach one million fibre connections by 2027 or sooner.
By the end of 2024 – one year ahead of schedule – CETIN achieved 97% population coverage with its 5G mobile signal. At the same time, the independent company Ookla confirmed that customers using CETIN’s infrastructure enjoy the highest available mobile data download speeds.
CETIN deployed Ericsson technologies to build its fifth-generation network and infrastructure, leveraging the high cybersecurity standards guaranteed by these solutions.
