Key Findings

HT wins overall Download Speed Experience, while A1 triumphs in 5G Download Speed

Our users in Croatia saw the fastest overall download speeds on HT’s network, clocking in at an average speed of 60.3 Mbps — more than 10 Mbps ahead of its rivals. However, it is A1 that wins the 5G Download Speed outright — with a score of nearly 275 Mbps. A1’s score was around 71.5 Mbps ahead of HT and Telemach who were statistically tied for second place. Both HT and Telemach jointly win the two upload speed awards — Upload Speed Experience and 5G Upload Speed.

Telemach claims the Availability award

Telemach wins only one award outright this time around — for Availability. Our users on this network spent 98.1% of the time connected to either a 3G, 4G or 5G signal. On top of their individual victories, HT and Telemach jointly win 5G Availability, with scores of 23.1% and 18.8% respectively. At the same time, A1 lagged behind its competitors, as our users on this network spent less than 10% of the time on 5G networks.

HT comes first in Video Experience, but A1 grabs 5G Video Experience

Similarly to both awards for download speeds — HT wins the overall Video Experience award outright, but the 5G Video Experience award ends in A1’s hands. HT claims Video Experience with a score of 66.9 points and was the only operator in Croatia to place in the Very Good (65-75) category — since both A1 and Telemach were rated as Good (55-65). However, looking at 5G Video Experience scores, all three operators placed in the Excellent (75 and above) category, which means fast loading times and almost non-existent stalling. As all operators placed in a higher category than for the overall Video Experience, this shows how 5G services can improve users’ mobile network experience.

The Excellent Consistent Quality award goes to A1

A1 met the minimum recommended performance thresholds for HD video, group video conference calls and gaming in 84.6% of users’ tests — and thus, wins the Excellent Consistent Quality award outright. The operator also jointly wins Core Consistent Quality, along with Telemach, after a statistical tie in the range of 93-93.2% of users’ tests that met the minimum recommended performance thresholds for lower performance applications including SD video, voice calls and web browsing.

A1 and HT jointly win both overall and 5G Games Experience awards

A1 and HT statistically tied for both overall Games Experience and 5G Games Experience awards, placing in the Good (75-85) category in both awards. This means most users deemed the experience acceptable and did not experience a delay between their actions and the game. A1 and HT also jointly win the overall Voice App Experience award. For 5G Voice App Experience, we saw the only instance of a three-way statistical tie between all Croatia’s operators in this report — and as a result, they all are joint winners.

Market Overview

We observed tightly-fought competition for the awards between Croatia’s operators. HT wins outright two awards — Video Experience and Download Speed Experience — while jointly claiming seven additional awards across the board. A1 completes the award haul, with three sole (5G Video Experience, 5G Download Speed and Excellent Consistent Quality) and five shared victories. Telemach grabs only one award outright, for Availability, while it also jointly wins five more awards. We saw only one three-way statistical tie in the awards table, as all three operators share the 5G Voice App Experience award.

Croatia is among the global 5G leaders in terms of speed, as in the latest Benchmarking the Global 5G Experience analysis published in March 2022, the country featured among the 5G Global Top 15 markets in 5G Download Speed, 5G Peak Download Speed and 5G Upload Speed. This is a result of Croatian operators’ active investment in their 5G infrastructure development. HT spent HRK10 billion ($1.5 billion) over the last six years, e.g. to secure the 5G spectrum, deploy its 5G infrastructure or develop the IoT services.

Telemach has also been investing in its 5G network and intends to cover all main cities along the Adriatic coast with the 5G footprint by the summer 2022. With the purchase of fixed broadband provider Optima Telekom, Telemach plans to enter the segment of converged services and soon offer bundled mobile and fixed telecommunications services to its customers.

Our results in this report are based on measurements collected across all major mobile operators in Croatia – A1, HT and Telemach – over the period of 90 days between December 1, 2021 and February 28, 2022, to see how they fared. 5G measurements contributed to the overall scores.

Opensignal’s Video Experience quantifies the quality of video streamed to mobile devices by measuring real-world video streams over an operator's networks. The metric is based on an International Telecommunication Union (ITU) approach, built upon detailed studies which have derived a relationship between technical parameters, including picture quality, video loading time and stall rate, with the perceived video experience as reported by real people. To calculate video experience, we are directly measuring video streams from end-user devices and using this ITU approach to quantify the overall video experience for each operator on a scale from 0 to 100. The videos tested include a mixture of resolutions — including Full HD (FHD) and 4K / Ultra HD (UHD) — and are streamed directly from the world’s largest video content providers.

In addition to Video Experience, we report on the following metrics related to video experience:

  • 5G Video Experience: The average Video Experience of Opensignal users when they were connected to an operator’s 5G network.
  • Video Experience – 5G Users: The average Video Experience of Opensignal users with a 5G device and a 5G subscription across an operator's networks. It factors in 2G, 3G, 4G and 5G video experience along with the availability of each technology.
  • 4G Video Experience: The average Video Experience of Opensignal users on an operator's 4G network.
  • 3G Video Experience: The average Video Experience of Opensignal users on an operator’s 3G network.

Opensignal’s Games Experience measures how mobile users experience real-time multiplayer mobile gaming on an operator’s network. Measured on a scale of 0-100, it analyzes how our users’ multiplayer mobile gaming experience is affected by mobile network conditions including latency, packet loss and jitter.

Games Experience quantifies the experience when playing real-time multiplayer mobile games on mobile devices connected to servers located around the world. The approach is built on several years of research quantifying the relationship between technical network parameters and the gaming experience as reported by real mobile users. These parameters include latency (round trip time), jitter (variability of latency) and packet loss (the proportion of data packets that never reach their destination). Additionally, it considers multiple genres of multiplayer mobile games to measure the average sensitivity to network conditions. The games tested include some of the most popular real-time multiplayer mobile games (such as Fortnite, Pro Evolution Soccer and Arena of Valor) played around the world.

Calculating Games Experience starts with measuring the end-to-end experience from users’ devices to internet end-points that host real games. The score is then measured on a scale from 0 to 100.

In addition to Games Experience, we report on the following metrics related to games experience:

  • 5G Games Experience: The average Games Experience of Opensignal users when they were connected to an operator’s 5G network.
  • Games Experience – 5G Users: The average Games Experience of Opensignal users with a 5G device and a 5G subscription across an operator's networks. It factors in 2G, 3G, 4G and 5G games experience along with the availability of each technology.
  • 4G Games Experience: The average Games Experience of Opensignal users on an operator's 4G network.
  • 3G Games Experience: The average Games Experience of Opensignal users on an operator's 3G (e.g. UMTS/HSPA or CDMA 1X EV-DO) network.

Definitions

Opensignal's Voice App Experience measures the quality of experience for over-the-top (OTT) voice services — mobile voice apps such as WhatsApp, Skype and Facebook Messenger — using a model derived from the International Telecommunication Union (ITU) approach for quantifying overall voice call quality and a series of calibrated technical parameters. This model characterizes the exact relationship between the technical measurements and perceived call quality. Voice App Experience for each operator is calculated on a scale from 0 to 100.

In addition to Voice App Experience, we report on the following metrics related to voice app experience:

  • 5G Voice App Experience: The average Voice App Experience of Opensignal users when they were connected to an operator’s 5G network.
  • Voice App Experience – 5G Users: The average Voice App Experience of Opensignal users with a 5G device and a 5G subscription across an operator's networks. It factors in 2G, 3G, 4G and 5G voice app experience along with the availability of each technology.
  • 4G Voice App Experience: The average Voice App Experience of Opensignal users on an operator's 4G network.
  • 3G Voice App Experience: The average Voice App Experience of Opensignal users on an operator's 3G (e.g. UMTS/HSPA or CDMA 1X EV-DO) network.

Definitions

Measured in Mbps, Download Speed Experience represents the typical everyday speeds a user experiences across an operator’s mobile data networks.

In addition to Download Speed Experience, we report on the following metrics related to download speeds:

  • 5G Download Speed: The average download speed observed by Opensignal users with active 5G connections.
  • Download Speed Experience – 5G Users: The average download speeds experienced by Opensignal users with a 5G device and a 5G subscription across an operator’s networks. It factors in 2G, 3G, 4G, and 5G download speeds along with the availability of each technology.
  • 4G Download Speed: The average downlink speed observed by Opensignal users when they were connected to 4G.
  • 3G Download Speed: The average downlink speed observed by Opensignal users when they were connected to 3G (e.g. UMTS/HSPA or CDMA 1X EV-DO).

Definitions

Upload Speed Experience measures the average upload speeds for each operator observed by our users across their mobile data networks. Typically upload speeds are slower than download speeds, as current mobile broadband technologies focus resources on providing the best possible download speed for users consuming content on their devices. As mobile internet trends move away from downloading content to creating content and supporting real-time communications services, upload speeds are becoming more vital and new technologies are emerging that boost upstream capacity.

In addition to Upload Speed Experience, we report on five supporting metrics related to upload speeds:

  • 5G Upload Speed: The average upload speed observed by Opensignal users with active 5G connections.
  • Upload Speed Experience – 5G Users: The average upload speeds experienced by Opensignal users with a 5G device and a 5G subscription across an operator’s networks. It factors in 2G, 3G, 4G, and 5G upload speeds along with the availability of each technology.
  • 4G Upload Speed: The average uplink speed observed by Opensignal users when they were connected to 4G.
  • 3G Upload Speed: The average uplink speed observed by Opensignal users when they were connected to 3G (e.g. UMTS/HSPA or CDMA 1X EV-DO).

Our availability metrics are not a measure of a network’s geographical extent. They won’t tell you whether you are likely to get a signal if you plan to visit a remote rural or nearly uninhabited region. Instead, they measure what proportion of time people have a network connection, in the places they most commonly frequent — something often missed by traditional coverage metrics. Looking at when users have a connection rather than where, provides us with a more precise reflection of the true user experience.

We also keep track of the instances that leave mobile users most frustrated: when there is no signal to connect to at all. The most common dead zones users struggle with occur indoors. As most of our availability data is collected indoors (as that’s where users spend most of their time), we’re particularly astute at detecting areas of zero signal.

Our availability metrics take a user-centric, time-based approach that complements the user-centric and geographical-based methodology used by our reach metrics.

Availability shows the proportion of time all Opensignal users on an operator’s network had either a 3G, 4G or 5G connection.
