Mobile network coverage of the motorways

In 2025, CTU carried out re-measurements of the coverage of motorways in the Czech Republic by mobile radiocommunication networks (2G, 4G and 5G), including verification of coverage inside tunnels. 

The measuring vehicle went through all the motorways in both directions and the measurement was performed on a per-second basis. Thus, CTU obtained the data with a density of every 25 meters. The data shows that there are also sections containing uncovered spots. If there are multiple spots in a row, users may perceive the entire area as uncovered because the mobile phone does not have enough time to log into the network. Thus, the subjective assessment of coverage may be lower than the coverage determined by the measurement.

The purpose of the measurement was to determine the current state of coverage of the motorway network and to inspect whether the development criteria set out in the frequency auctions were met. Taking into account the objective facts allowed by the auction conditions (e.g. the coverage obligation is deferred for new sections of motorways), the measurement showed that the operators' obligations have been met.
