The Opensignal study, which collected and analysed data from April to June of this year, provides a detailed view of the experience and service quality that Czech mobile operators deliver to their customers. T-Mobile took first place for the best mobile network by winning the majority of the monitored categories, thereby further improving its score from the previous report.
"We are raising the bar for network quality in the Czech Republic. Our continued investment in infrastructure is delivering a faster, more reliable and consistently better experience for our customers. Defending the Opensignal award for several years is clear recognition that our long-term strategy is working – and that our customers are experiencing the difference," added Carlos Fernandes, Chief Technology Officer of T-Mobile Czech Republic and Slovak Telekom.
T-Mobile performed best in the network quality measurements for both download and upload. It won the download speed category by a wide margin, with users achieving 72.3 Mb/s – a lead of 28 Mb/s over second place. Download speeds within the 5G network increased by 23 Mb/s compared with the previous report.
The operator also succeeded in the consistent quality of connection assessment – the network's ability to deliver stable and reliable services over the long term. Opensignal further recognized T-Mobile for the best mobile network coverage and the best 5G coverage in the Czech Republic, confirming the broad availability of services and the largest geographic reach of its 5G network on the market.
The analytics company Opensignal collects data every day through billions of measurements worldwide, covering diverse groups of research participants, demographic profiles, devices, and network conditions. The data collection process is automated, ensuring continuous testing in real-world conditions both indoors and outdoors, across various network types. Measurement accuracy is ensured by using common internet servers such as Google, Akamai, and Amazon CDN, providing a genuinely representative view of the network experience without operators being able to influence the measurement results in any way.
