2019│02│05 – The Mobile Network Test in Switzerland
THIS YEAR, WE HAD TO SLIGHTLY POSTPONE OUR RENOWNED AND SOPHISTICATED NETWORK TEST FOR SWITZERLAND: BUT NOW; FOLLOWING THE PUBLICATION OF THOSE FOR GERMANY AND AUSTRIA IN DECEMBER 2018 THE SWISS RESULTS ARE ALSO AVAILABLE:
Due to logistical reasons, we had to schedule our Great Mobile Network Test in Switzerland a little later than its equivalents for Germany and Austria (see connect 1/2019). From November 28 to December 20, two of umlaut‘s drivetest vehicles equipped with sophisticated measurement gear visited 18 larger cities and 31 smaller towns in Switzerland, together covering a total of 6,500 kilometres. Of these, 3160 km accounted for the connecting roads between the cities and towns. Those measurements by car were complemented by walktests, conducted in eight Swiss cities, as well as by test journeys performed on Swiss trains.
Results enthusiastically awaited
Not just the Swiss operators and their customers, but also participants and users from other countries, eagerly expected the results. The reason for this anticipation is that the results of our network test in Switzerland traditionally range on a very advanced level – ahead of those from Germany and Austria. Once again, the Swiss operators gave each other a neck-and-neck
race. The 2018 network test in Switzerland resulted in a tie of
Sunrise and Swisscom. This time we have a clear winner, though
with a very narrow margin.
THIS DISCIPLINE ALREADY DEMONSTRATES THE HIGH PERFORMANCE LEVEL OF THE SWISS MOBILE NETWORKS.
While Swisscom and Sunrise have already rolled out Voice over LTE (VoLTE) in their networks and additionally support the modern EVS codec („Enhanced Voice Services“), Salt‘s network does not yet offer this improved voice mode. Looking at the results of the drivetests conducted in 18 larger Swiss cities, Sunrise scores ahead of Swisscom in the voice discipline. Among other factors, this might be explained with the fact that almost a 100 per cent of the test calls set up in the Sunrise network could be established via LTE – thus allowing for fast call setup times. But even though Salt customers still have to use the older circuit-switched fallback (reverting to 3G) in order to conduct phone calls, they also get high voice quality and reliability.
In the walktests conducted within the larger cities, Swisscom leads by a narrow margin. In the smaller towns, Sunrise is ahead. Salt manages to keep up in the examined larger cities, but when it comes to the 31 smaller towns, this smallest Swiss operator falls a little behind.
Similar results can also be observed on the connecting roads, where Swisscom and Sunrise impress with a success ratio of 100 per cent. In such a strong environment, even Salt‘s high success ratio of about 97 per cent looks almost like a weak result. But as this operator also shows longer call setup times and a lower voice quality MOS, Salt overall falls a little behind on the connecting roads. Still, the partial scores of our telephony tests all in all range on a pleasantly high level.
This is also true for the measurements performed on the Swiss railways. Here, the operators from Switzerland traditionally demonstrate to their peers in Germany and also Austria what a leading performance means. This year makes no exception to this rule – particularly the success ratios and setup times of calls initiated while travelling on the trains score in a range that providers and customers from the neighbouring countries can only dream about.
WHEN IT COMES TO DATA COMMUNICATIONS, THE SWISS OPERATORS ONCE AGAIN COMPETE AT THE HIGHEST LEVEL.
DATA ON RAILWAYS
IN ORDER TO CONSIDER IN TH USER EXPERIENCE OVER LONGER PERIODS AND ALSO LOCATIONS OFF OUR TEST ROUTES AND PLACES, THE RESULTS OF CROWDSOURCING ANALYSES ARE INCLUDED WITH 15 PER CENT IN THE OVERALL EVALUATION.
We have filtered a small number of outliers with conspiciously good results from our crowd evaluation as we could not absolutely exclude
the suspicion of fraud. Further details about this can be found in
the online version of this test on www.connect-testlab.com. High values for the crowdsourced network coverage for voice and 4G once more emphasise the good network performance in Switzerland. Also the “quality of coverage“ (how often the customers could have actually used a respective network technology) is pleasantly high.
