CETIN a.s.

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 in the Czech Republic is to build, operate and develop a reliable, secure and fast telecommunications infrastructure. This mission is an essential part of digitalisation and support for the Czech economy’s competitiveness. 

CETIN owns and runs the largest electronic communications network in the Czech Republic and is a wholesale telecommunications services provider. The company offers its services on equal terms to all telecommunications operators and internet access providers that supply 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 offers data services for corporate networks and data centre leasing. CETIN also offers international voice services for domestic providers and more than 200 telecommunications operators worldwide. 

As the operator of the largest communication infrastructure in the Czech Republic, CETIN invests billions of Czech crowns annually in development. In 2023, the company continued to build FTTH fibre-optic connections, which accelerated the average speed available in the network to 289 Mbps. 

Last year, CETIN continued to roll out 5G mobile technology across the Czech Republic. The complete replacement of technologies used in the mobile access network raised the network’s overall capacity and quality of services. By the end of 2023, 5G connectivity was available to 87% of the population in Czech Republic. CETIN has deployed Ericsson technologies to build its fifth-generation network and infrastructure, leveraging the high cybersecurity standards guaranteed by these solutions.
