Fixed line test 2021: This is how connect & zafaco test

This is how connect and zafaco test

Connect has been carrying out its demanding landline test in close cooperation with zafaco GmbH, based in Ismaning, since 2009. It operates test connections in a total of 42 cities, although not every network operator at every location with a connection takes part in the test.

With our test candidates, we differentiate between supra-regional, i.e. nationwide active providers, and regional providers whose connections are only available in certain federal states or regions. National providers take part with a total of 16 test connections, regional providers with four.

When selecting the access products for each provider, connect and zafaco pursue the goal of approximating the actual offers on the market. Because not every customer uses the fastest and most expensive lines. That is why the distribution of the connections across different bandwidth classes takes into account the range of services offered by the network operators. The complete list of the connection types considered in the test field can be found here:

For the assignment to bandwidth classes and for the evaluation of some measured values, we have to check which services a provider actually appeals to its customers. For reasons of fairness, we also check whether the tested connection types are really marketed in this way. We check both on the basis of the product information sheets prescribed by the Federal Network Agency. Every provider has to make these technical descriptions publicly available – they can be found quickly using a Google search.

Automated test systems were used at the locations from May 17. by June 13th, 2021 (exception Vodafone, see here) a total of around 2.4 million measurements. So that maintenance work that cannot be postponed does not lead to unfair disadvantages, zafaco considered a nightly maintenance window and did not record any measured values ​​between 2 a.m. and 6 a.m. This maintenance window does not apply to the crowdsourcing measurement results.

Measurements of telephony, data transmission, web services and web TV were carried out automatically around the clock. The terminals officially offered by the providers with the latest firmware were used at the tested connections. However, connect and zafaco have the principle that only configurations that are actually available to the customer take part in the test.

Therefore, in coordination with the network operators, it was determined before the start of the test with which firmware version the routers were allowed to participate. You can find an overview of the end devices used and their firmware versions here:
