In previous years, the measurements that connect test partner zafaco carried out in Austria and Switzerland ran simultaneously – even if we then published the results in two consecutive issues of connect.

We are deviating from this practice this time: in 2022 we will be examining the broadband and fixed network offers in both German-speaking Alpine countries at the same time.

As in previous years, zafaco monitored the tested networks throughout the year. Even in the third year of the Corona pandemic, we can therefore be sure that the changed requirements and usage habits due to home office, home schooling and the streaming boom did not mean an unfair disadvantage for the network operators.

In fact, all providers can handle this load with ease – and with the new VoIP test case, our test program also takes the changed usage patterns in the networks into account.

Results not fully comparable with Germany

The very high level of performance observed in the present test proves that the providers have now adjusted to the new normal. However, it should be pointed out that the test results in the two Alpine countries are not 1:1 comparable with the results of our test in Germany due to different methods.

For example, the VoIP constellation considered in this test deviates from the telephony tests in Germany. And there are still no comparable public data sources in the two Alpine countries for the crowdsourcing considered part of the assessment in the neighboring country to the north. This leads to a different distribution of points. However, the latter is identical for the two Alpine countries presented here.

In addition, there are also country-specific threshold values ​​that do justice to the different service levels in the fixed networks. However, we would like to emphasize once again that our test results reflect the end-to-end performance of the respective networks – they therefore do not reflect the average of all connections laid in the respective country. But enough of the preamble, curtain up for the results.

New test case for web services: Now with VoIP

In their broadband and fixed network tests in Austria and Switzerland, zafaco and connect do not evaluate traditional telephone connections via the fixed network. Because of the cheap mobile phone tariffs in the Alpine countries, this type of communication does not play the same role there as it does in neighboring Germany.

Nevertheless, we have included a telephony-based use case in this year’s test program for Austria and Switzerland: Voice over IP in the Web Services category. This test case depicts a constellation that can often be found online due to the massive increase in home office work since the pandemic: Branch offices or home office users make IP-supported calls to each other or to a company headquarters – outside the public telephone network.

So-called softphones – VoIP clients designed as apps – are usually used as end devices in home offices. However, specialized IP telephones, for example in a branch of the company, can also be connected in this way. The telephony connections are made via the SIP-Protocol (Session Initiation Protocol) and then overflow RTP (Realtime Transport Protocol).

The encoding is typically done using audio codecs such as G.711 or G.722. The measurement clients from zafaco map exactly this constellation: They set up a VoIP connection to a central test server, the remote station in the company headquarters, using the protocols mentioned, and then determine the end-to-end voice quality of the telephone connection implemented in this way.

Standardized speech samples of male and female voices are transmitted in both directions of communication and compared with the original. The measurement units record the connection setup time, error rates, language propagation times and the MOS-Wert ( Mean Opinion Score, average quality indicator) of the voice quality according to the ITU-T standard P.863 POLQA (Perceptual Objective Lplease Quality Aanalysis). The values ​​determined in this way allow conclusions to be drawn about the suitability of an Internet connection for the application described, which is important in practice.
