OpenSignal users clocked up average download speeds of 35.3 Mbps on the Sunrise network during the tests conducted in February-April. That was 12 Mbps faster than its nearest rival Salt (23.3 Mbps) and nearly 15 Mbps more than Swisscom (20.7 Mbps). All three operators were doing better than the researcher's global average of 17.4 Mbps over LTE networks.
Swisscom performed the best on LTE latency of the three operators and tied with Sunrise on availability over 4G (76%). Salt was not far behind with 4G available nearly 70 percent of the time. Overall, Open Signal found that Swiss mobile users connect to LTE every seven out of ten attempts and average an LTE speed of well over 20 Mbps.
The Open Signal measurements are based on data collected from its end-user mobile applications rather than drive tests. It collected nearly 49 million data results in the three-month period, from over 6,100 users.
