Key findings

Chunghwa wins three major Opensignal awards outright, again

Alongside clear wins in the Download Speed Experience, Video Experience and 4G Coverage Experience categories, Chunghwa also jointly wins the Voice App Experience award. However, it has lost out on Games Experience, losing the joint victory it had in that category in the last report.

Upload Experience is won again by FarEasTone

With an Upload Speed Experience of 11.1 Mbps, FarEasTone wins the award outright — and for the fourth time in a row —, ahead of Chunghwa on 9.7 Mbps and Taiwan Mobile's score of 9.4 Mbps. Upload Speed Experience is important for sharing large files and media.

Taiwan Mobile and FarEasTone jointly win the Games Experience award

In a close contest, the two operators win with scores of 77.0 and 77.5 respectively on the 100 point scale placing them in the Good category. However, in our 5G report two operators — Chunghwa and FarEasTone — achieve an Excellent experience. Games Experience reflects the real-time multiplayer mobile gaming based on measurements taken on mobile networks.

All five operators have high 4G Availability scores.

The time users are able to connect to 4G service — 4G Availability — remains an important foundation for 5G services, because current 5G deployments require users to connect to a 4G signal as well. While GT narrowly wins the 4G Availability award, Chunghwa wins the 4G Coverage Experience award again with a score of 9.8 on the 10 point scale.

Introduction

Taiwan's mobile market is extremely dynamic with fierce competition across operators. However, much of the innovation has now moved onto the 5G market. In this report we analyze the overall mobile network experience of users. The awards include real-world measurements taken with 5G as well as older mobile network technologies.

Opensignal also reports on the 5G experience in a companion report which compares our 5G users' experience with Taiwan's leading 5G operators. In this new report we launch a number of new national 5G awards, including: 5G Games Experience, 5G Video Experience, 5G Voice App Experience, 5G Upload Speed and 5G Reach.

National Analysis

Video Experience

Three operators enabled our users to enjoy an Excellent Video Experience (75 or above), the award winner Chunghwa as well as Taiwan Mobile and FarEasTone. Excellent means users saw a very consistent experience across video streaming providers and resolutions tested, with fast loading times and almost non-existent stalling.

Opensignal's Video Experience quantifies the quality of video streamed to smartphones by measuring real-world video streams over operators' networks. The score is based on an International Telecommunication Union (ITU)-based approach, built upon detailed studies which have derived a relationship between technical parameters — such as picture quality, video loading time and stall rate — with the perceived video experience as reported by real people. The videos tested included a mixture of resolutions and were streamed directly from the world's largest video content providers.

Games Experience

Joint winners FarEasTone and Taiwan Mobile's users enjoyed a Good Games Experience, meaning most users deemed the experience acceptable. Gameplay experience was generally controllable and the user received immediate feedback between their actions and the outcomes in the game. Most users did not experience a delay between their actions and the game. While Chunghwa had a lower Games Experience score than the two winners, its users also had a Good experience.

The Games Experience quantifies the experience playing real-time multiplayer mobile games on mobile devices. 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, PUBG and Arena of Valor) played around the world.

Voice App Experience

Three operators jointly win the Voice App Experience award: Chunghwa FarEasTone and Taiwan Mobile. This award measures the quality of experience for over-the-top (OTT) voice services — for example, of mobile voice apps such as WhatsApp, Skype and Facebook Messenger — 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. 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.

Download Speed Experience

Chunghwa wins the Download Speed Experience award again. The score reflects the average download speed experienced by Opensignal users. FarEasTone ranked second followed by Taiwan Mobile. These three positions were identical to those we saw in our last report in December 2020. Download Speed Experience includes measurements from all mobile network technologies.

4G Availability

GT wins the 4G Availability award outright with a score of 96.8% when previously it shared the award with FarEasTone and Taiwan Mobile. 4G Availability reflects the time our users are able to connect to a 4G service using each operator.

4G Availability is an important foundation for 5G services because almost all current 5G deployments globally are using what is called non-standalone access (NSA)) this means a 5G user must also be connected to a 4G service in order for the 5G connection to operate.

4G Coverage Experience

All five operators have high scores for 4G Coverage Experience, but Chunghwa again wins the Opensignal award with a score of 9.8 on the 10 point scale. Opensignal's 4G Coverage Experience metric is a measure of how mobile subscribers experience 4G coverage on an operator's network. Measured on a scale of 0-10, it analyzes the locations where customers of a network operator received a 4G signal relative to the locations visited by users of all network operators.

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.
