When Germany talks about the network quality, the providers are often scolded and the gaze wanders enviously to nearby Switzerland or distant South Korea. However, the focus is mostly on the mobile network, the expansion of which has been driven by new innovations for decades.
But with the contact block imposed by the rampant corona virus, the fixed network is becoming the focus of interest. Because instead of meeting in restaurants or pubs, the telephone is suddenly the means of communication with friends and relatives. Instead of going to fitness clubs, playgrounds and sports fields or at concerts, you spend your free time in your own four walls, which binge watching almost automatically ranks as the number one leisure activity.
Instead of meeting colleagues and customers in meeting rooms or on business trips, video calls and chats via Skype, Zoom and Microsoft Teams are on the roster. And instead of transferring data from one workplace to another on their own intranet, they are now sent from one home office to the next via bandwidth-intensive VPN tunnels. The resulting increase in traffic is a worst-case scenario for which the networks could not be prepared.
Measurements from 52 cities in Germany
To what extent they are able to meet this challenge, connect had its long-established fixed network test partner zafaco GmbH check. 110 network parameters that were decisive for network quality were examined from March 1 to March 30 to see how the contact restrictions imposed since March 13 had an effect on the services used.
For analysis, zafaco uses measuring points distributed over 52 cities, which take into account the different performance classes of the connections of all leading fixed network and broadband providers. With one hour of maintenance windows per day, the quality parameters are recorded 23 hours a day, 7 days a week and 365 days a year, from which an extremely detailed picture of the performance of the network providers is obtained.
