Key findings

Our Vodafone users observed the fastest average download and upload speeds

Vodafone has won both our speed awards — Download Speed Experience and Upload Speed Experience — by impressive margins. Our Vodafone users enjoyed average download speeds that were 8.4 Mbps (23.1%) faster than their counterparts on second-placed T-Mobile. In addition, Vodafone’s Upload Speed Experience score was 1.3 Mbps (9%) faster than that of T-Mobile, which again had the second-highest score.

Opensignal’s users in the Czech Republic enjoy an Excellent Video Experience

Our Video Experience metric quantifies the quality of video streamed to mobile devices by measuring real-world video streams over operators’ networks. Across all three national operators, our users had an Excellent Video Experience in the 90 days ending January 29 2021. This indicates a very consistent experience across all users, video streaming providers and resolutions tested, with fast loading times and almost non-existent stalling. Vodafone won the Video Experience award by a margin of at least 2.4 points out of 100 (3.2%).

Vodafone comes up top for mobile multiplayer gaming

Vodafone has won our Games Experience award and our users on its network were the only ones who enjoyed an Excellent Games Experience — with those on O2 and Vodafone’s networks having a Good experience instead. Opensignal’s Games Experience metric is a measure of how mobile users experience real-time multiplayer mobile gaming on an operator’s network. Measured on a scale of 0-100, it analyzes how the multiplayer mobile Games Experience is affected by mobile network conditions including latency, packet loss and jitter to determine the impact on gameplay and the overall multiplayer Games Experience.

Vodafone wins on Voice App Experience, but our Czech Republic users had a Good experience on all three operators’ networks

Opensignal's Voice App Experience measures the quality of experience for over-the-top (OTT) voice services — mobile voice apps such as WhatsApp, Skype, Facebook Messenger etc. — using a model derived from the International Telecommunication Union (ITU)-based approach for quantifying overall voice call quality and a series of calibrated technical parameters. Vodafone has won the award for this measure of the mobile experience outright — its score of 84.2 out of 100 beat that of second-placed T-Mobile (83.3) by 0.8 points. However, our users on all three national operators enjoyed a Good Voice App Experience, which means that many users were satisfied, but some experienced minor quality impairments, with clicking sounds or distortion being very occasionally present.

Our Vodafone users spent the most time connected to 4G services

Vodafone has won our 4G Availability award outright with a score of 93.6%. This means that our Vodafone users on average spent 93.6% of their time connected to 4G services. Our users on all three operators’ networks observed 4G Availability scores that were higher than 90%. This, together with 4G Coverage Experience scores of 9.4 or higher out of 10, points to the maturity of Czech operators’ 4G network deployments.

Introduction

Our first analysis of the mobile experience at the operator-level in the Czech Republic reveals that Vodafone has come up top for six out of seven of our metrics, winning all three of our experiential awards (Video Experience, Games Experience and Voice App Experience), both our speed awards (Download Speed Experience and Upload Speed Experience) and our 4G Availability award. The only award it did not win was that for 4G Coverage Experience, which was won by O2. Vodafone’s lead was particularly strong in Download Speed Experience, as our Vodafone users observed average download speeds that were an impressive 8.4 Mbps (23.1%) faster than their counterparts on second-placed T-Mobile.

While O2 won the 4G Coverage Experience award, it placed third in four measures of our mobile experience and our users on its network observed average download speeds that were 8.1-16.6 Mbps slower than their counterparts on T-Mobile and Vodafone.

Looking more widely at the Czech mobile landscape, some of the most important recent developments include efforts by operators to modernise their networks and boost capacity by moving away from 3G — which is less spectrally efficient than newer mobile technologies — and the release of 5G spectrum to support their 5G rollouts. Vodafone claimed earlier this month that its 5G network is now present in more than 130 cities and smaller municipalities and that it now covers more than 20% of the population. The operator also said that it will switch off its 3G network at the end of March. In addition, in a recent spectrum auction, the three national operators obtained all of the 700 MHz spectrum that was on offer and half of the spectrum that was put up for auction in the 3400 MHz-3600 MHz band, with the remainder going to CentroNet and Nordic Telecom 5G. On the back of its purchases of a 20 MHz block in the 3400 MHz-3600 MHz band, Nordic Telecom 5G said that it is seeking to launch mobile services and strengthen its position in the fixed line internet market.

In this report we examined the mobile network experience of the three main mobile network operators in the Czech Republic: O2, T-Mobile and Vodafone, over a period of 90 days beginning November 1, 2020, to see how they fared. We have used 5G measurements in addition to those from previous generations of mobile network technology when determining the overall scores for each metric.

Opensignal measures the real-world experience of consumers on mobile networks in the places they live, work and travel.

We continually adapt our methodology to best represent the true experience of smartphone users. Therefore, comparisons of the results to past reports should be considered indicative only.

For every metric we calculate statistical confidence intervals indicated on our graphs. When confidence intervals overlap, our measured results are too close to declare a winner. In those cases, we show a statistical draw. For this reason, some metrics have multiple winners.

In our bar graphs we represent confidence intervals as boundaries on either sides of graph bars. In our supporting-metric charts we show confidence intervals as +/- numerical values.
