The O2 operator notes that it is fully aware of the warehouse station technology implemented for it by the Cetin company, although it is financially and logistically a lower road, but it has a significant impact on its orders. As a result, not only the name covered by the 5G signal, which was repeated this year by the Czech University of Technology (VUT) in Japan, but also the name of the NetMetr server, have to prove it.

The highest download speed was determined using the nPerf application, where O2 reached 704 Mbit/s, very similar results were obtained using Speedtest, where O2 reached 636 Mbit/s, Vladimr Da from the BUT Cyber ​​Resistance Center stated that these speeds are roughly double compared to competition. It is attributed to using a frequency of 3.7 GHz with a sufficient channel (40 MHz).

Competitor Vodafone, according to the press statement of Ondej Lutinca, for its 5G will use both the frequency after 3G is turned off (2,100 MHz) and the 700, 1,800 and 3,500 MHz bands. T-Mobile also used the 2,100 MHz band for the development of its 5G network, and is currently also building it on the 1,800 MHz frequency, and was the first domestic operator to use the previously leased 700 MHz band for its development. We are piloting it to use 3,500 MHz bands, Martin Orgonk, editor for external relations and sustainability, informed the editors of

Last year, T-Mobile excelled

According to Vladimr Di from BUT, O2’s current lead is especially among the average performed names, where this operator achieves an average download speed of 217 Mbit/s, while in the case of the competition it is 117 Mbit/s and 87 Mbit/s.

Download speed

For example, in this quarter, T-Mobile came out as the best in Speedtest speed tests. As a result of the post-processing, the mobile station reached 58.82 points at the speed of that time, while its competition faltered significantly: O2 finished second with a result of 44.71 points, Vodafone followed with 42.37 points.

In terms of latency, i.e. response speed, O2 took first place with 22 milliseconds, T-Mobile was with 28 ms and on Tet PC. Vodafone, which was only two milliseconds behind O2 in latency, excelled in stability st. In 93% of the cases, it managed to provide at least 5 Mb/s for downloads and 1 Mb/s for uploads, while it was 90.3% for O2 and only 88.6% for T-Mobile.

In the fourth quarter of 2020, Vodafone was the first to come out of the Speedtest speed test (59.98 points), followed by T-Mobile (53.21 points) and O2 (30.86 points). At the time, O2 (25 ms) was first in ppad latency, followed by Vodafone (27 ms) and T-Mobile (34 ms). As for stability, Vodafone took first place (consistency 96%), followed by T-Mobile with 91.7% and O2 (88.1%).

O2 still excels in latency

The 5G speeds achieved by O2 thanks to a technological leap are confirmed by the operator as well as on the NetMetr server, according to which O2 has achieved the lead in the last six months (as of the 15th edition). For example, the average download in its 5G network reaches 185 Mbit/s, compared to less than 75 Mbit/s at the competition.


The O2 has the same sharp jump in response speed. This is a must for those who play online games or communicate online using a video call, for example when working from home. According to NetMeter, the O2 operator has a response time of only 14.5 ms, while the competition is around 24 ms, said O2 technical editor Jan Hruka.

This route is also suitable for larger capacity on individual stations and thus better coverage in a given area. In this context, Hruka added that the capacity as a whole is very important, because the volume of traffic doubles every 18 months.

O2 current blood 5G is more than 2.6 million inhabitants of the Czech Republic, this year in May it was about two million. For example: competitor Vodafone reached 60% coverage last December, this year in May, he announced coverage of 70% of the populationT-Mobile has already covered 26% of the population (roughly 2.8 million inhabitants) with its high-speed service.
