Funkloch App: Federal Network Agency Publishes Map with Results

President Homann reflects on the results: “For the first time, the Funkloch app gives users a complete overview of network availability – and it already has data from 160 million test points.”

Today the Federal Network Agency published an up-to-date map with the results from the broadband measurement / dead zone app. The map can be viewed at

“It’s great to see how 187,000 users have installed this app already in the first year. So far, users have sent data from a total of almost 160 million test points. We are now able to look at the results from these users and compare them with our own findings, for example,” says Jochen Homann, president of the Federal Network Agency.

Dead zone map

The map with the measurement results is divided into honeycombs which can be zoomed in on to nine levels. The results can be filtered according to technology, network operator and time period. The colour of the honeycombs depends on which filters are set.

The test points are neither evenly distributed throughout the federal republic nor within a honeycomb. The more test points delivered by different users, the more meaningful the results. Results may vary by region and network.

Moreover, it should not be forgotten that the test points from app users were generated by their end devices and mobile phone contracts. The map may therefore not provide conclusive information about the availability of an operator’s network technologies at a certain location.

Broadband measurement / Funkloch app

On 30 October 2018 the Federal Network Agency released a version of its broadband measurement app on behalf of the Federal Ministry of Transport and Digital Infrastructure. This version comes with a network availability / dead zone detection extension. With the app, users can record whether there’s a dead zone or a mobile phone connection where they are, and which mobile phone technology (2G, 3G, 4G, 5G) is used.

The broadband measurement / Funkloch app was developed by zafaco GmbH for the Federal Network Agency and is available free of charge for Android and iOS in the respective app store.
