David Hanak Analytical company Opensignal has published a very interesting study in which it focuses on the quality of 4G connections in countries around the world. The study took place all last year, within which more than half a billion measurements were taken from a total of more than 94 million devices. The results point to the quality of 4G networks in individual states and the differences between them. The Czech Republic came out very well from this study.

The study focused on 4G networks in 77 countries around the world. The main point for measurement was the available connection speed, the variability of the connection speed depending on the time of day and the aggregation of 4G connections in real traffic.

If we focus on the individual partial results, the measurements show that the 4G network "runs" best around 3 a.m., when it has the lowest traffic. It gradually increases during the day and culminates in the evening, when transmission speeds significantly slow down in selected countries. We will stop at them for a moment.
The study collected the results of the highest transmission speeds achieved at the ideal time of day for each state in which the measurement took place. The Czech Republic was ranked 28th (out of 77) in this ranking with an average transfer speed in ideal time of 35,8 Mb/s and an average overall transfer speed of 33 Mb/s. In terms of purely transfer speeds, South Korea is the best with an average ideal value of 55,7 Mb/s. You can view the ranking of other states in the gallery below. The entire list is then in the referenced study.

However, speed is definitely not everything, the study also measures the difference between the highest and lowest speed achieved during the day. What is the point of a fast 4G network with a transmission speed of over 50 Mb/s, when it is only able to offer this speed early in the morning and late at night. And it is precisely in this respect that the Czech 4G network is first among all measured countries. The difference between the lowest and highest average measured speed is the lowest of all countries. So even if we don't have the fastest 4G networks in the world, they are at least very consistent in terms of connection speed. The other end of the imaginary barricade is occupied by Belarus, where the difference is more than 30 Mb (8 - 39 Mb/s).
The last interesting data from the study points out which specific hours are the worst for individual states in terms of the overall slowdown of the 4G network. As already stated above, in the Czech Republic we do not suffer from very large fluctuations in connection speeds, but if you are wondering when the 4G network is most heavily loaded, according to the data, it is at 9 o'clock in the evening, when the average connection speed drops to 29,7 Mb/s .
