umlaut tested and measured the performance of its voice

services on smartphones in comparison to other LTE/

UMTS/GSM mobile radio networks in metropolitan and

rural areas of Greece.

The audit was done as a performance benchmark

performed by umlaut between 07.02.2020 and 25.2.2020

in cities and towns as well as on connection roads.

Dedicated measurements have been executed as drive

tests outdoors using a Samsung Galaxy S9 (G960FDS)

Methodology.

The leader in mobile benchmarking, umlaut, has analyzed

the mobile networks of Greece with regards to mobile

network performance. We measure smartphone voice

performance based on extensive drivetests – from major

metropolitan areas to smaller cities and connection roads.

We objectively define the routes and test methodology

and publish the results through certificates or public

benchmark reports.

As the de-facto industry standard, our benchmarking

methodology 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.
