Geographically, Cologne is located almost exactly between the headquarters of Telekom (Bonn) and Vodafone (Düsseldorf) – even if the proud people of Domstadt are likely to speak of this point of view more widely.

In any case, the drive and walk test teams from umlaut did not have to travel too long from their company headquarters in Aachen for their voice and data measurements. In this case, Bonn wins the race – Deutsche Telekom scores “outstanding” here.

But the competitors from Düsseldorf and Munich also achieved very good results. Telefónica managed to place itself nine points behind Vodafone in the overall standings.

The individual consideration of the three test categories leads to different strengths: Telefónica leads in the language discipline, closely followed by Vodafone. Crowdsourcing gives Telekom first place, but then puts Vodafone in second place and Telefónica in third place.

In this case, too, it should be noted that in the crowd analyzes, not only the performance of the networks, but also the different preferences for tariff and device performance classes depending on the clientele of the provider have an influence on the result.

Telekom made the local victory in the data category clear – this is where the gaps between the opponents are clearest – with Vodafone, interestingly, falling behind in the walk tests. One could almost think that, from a Düsseldorf perspective, it is better to drive through Cologne than to walk around there.

A look at the map of the pro “Evaluation Area” reveals a relatively balanced picture. In the city center, Telekom and Vodafone compete, Telekom shows strengths, among other things, in trinkets, parts of Ehrenfeld and Mühlheim. Vodafone is ahead in parts of Rodenkirchen and Chorweiler. And Telefónica / O2 has strongholds in the north of Porz and parts of Lindenthal and Mülheim.
