What did the cnlab.ch October 2024 to September 2025 measurements show about Swiss 4G/5G download speeds?
In the cnlab.ch measurement window from October 2024 to September 2025, Swisscom led average 4G/5G downloads, followed by Salt and then Sunrise.
Average download speeds (4G+5G combined, cnlab.ch data, October 2024 - September 2025):
| Operator | Avg Download Speed | Trend |
|---|---|---|
| Swisscom | ~350-450 Mbit/s | Consistently highest, peaked ~450 Mbit/s in Apr 2025 |
| Salt | ~170-260 Mbit/s | Second place, relatively stable around 200 Mbit/s |
| Sunrise | ~80-140 Mbit/s | Third place, fluctuating around 100 Mbit/s |
Context: These are averages across all tests, all technologies (4G and 5G). Individual speeds vary enormously based on location, time of day, and whether you're on 4G or 5G.
Swiss MNOs (Mobile Network Operators): Switzerland's three physical network operators each have a Mobile Country Code (MCC) 228 with different Mobile Network Codes (MNC): Swisscom (01), Sunrise (02), Salt (03). MVNOs (Mobile Virtual Network Operators) like M-Budget, yallo, or Lidl connect piggyback on one of these three physical networks.
Why this matters: Mobile-security analysis often needs real operator context. A theoretical LTE or 5G speed tells you what the standard permits; measurement datasets show what users actually experienced in a specific country and time window.
