PPF Telecom Group companies have launched a major revamp of the mobile network across the Czech Republic. The billions of crowns that CETIN is investing in upgrading its network for the transition to 5G technology include the replacement of radio technology. Ericsson equipment will make it possible to use all of O2’s frequency bands in both 4G and 5G.
As part of this change of technology, the old 3G network will be phased out in a move that will free up frequencies for high-speed data services so that 5G technologies can be deployed in the nationwide 1800 MHz band and the high-capacity 3.7 GHz band. The entire network upgrade in the Czech Republic should be completed within three years.
