umlaut communications GmbH tested and measured the

performance of its voice and data services on smart-

phones in comparison to other LTE/UMTS/GSM mobile

radio networks in metropolitan and rural areas of Czech

Republic.

The audit was done as a performance benchmark

performed by umlaut communications between 17.10.2019

and 01.11.2019 in cities and towns as well as on connection

roads.

Dedicated measurements have been executed as drive

tests outdoors using a Samsung Galaxy S9 cat18 Smart-

phone 1200 Mbit/s Download / 200 Mbit/s Upload.

All data measurements have been performed in 4G

preferred mode. Voice measurements have been done in

4G/4G preferred mode on both sides, while call origin has

been alternated.

In addition crowdsourced performance data has been

collected and evaluated between CW20 2019 and CW43

2019.

Claims Methodology

The leader in mobile benchmarking, umlaut, has analyzed

the mobile networks of Czech Republic with regards to

mobile network performance. We measure smartphone

voice and data performance based on extensive dri-

ve-tests – from major metropolitan areas to smaller cities

and connection roads.

We objectively define the routes and test methodolo-

gy and publish the results through certificates or public

benchmark reports.

As the de-facto industry standard, our benchmarking me-

thodology focuses on customer-perceived network quality

and covers a wide range of mobile services.

Today, more than 200 mobile networks in more than

120 countries are being evaluated by our unique scoring

methodology. It allows a technical analysis that is unpre-

cedented in its level of detail and enables comparisons

between the network performance and capability of each

mobile network. Our public benchmarks as well as the

certificate benchmarks help network operators to demon-

strate how well they are delivering wireless connections to

consumers, business users and enterprises and reveals the

areas of improvement.
