Claims Methodology

The leader in mobile benchmarking, umlaut, has analyzed

the mobile networks of Hungary with regards to mobile

network performance. We measure smartphone voice and

data 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.
