Multi-channel strategy for public information, warning and alerting
In light of growing challenges such as extreme weather events and other hazardous situations, Switzerland continues to rely on a diverse, multi-channel strategy to alert the population. To this end, the Federal Office for Civil Protection (FOCP) has developed a strategy to modernise the alerting and information systems over the next ten years. The siren network will remain in place while the use of mobile phone alerts (via cell broadcast) and digital channels will be expanded.

The siren network will remain in place while the use of mobile phone alerts (via cell broadcast) and digital channels will be expanded.
Focus on digital channels
The introduction of cell broadcast technology is expected to significantly improve the way in which the population is warned and alerted. Cell broadcast makes it possible to send short text messages directly to all mobile phones in a defined area. The Alertswiss app and website will also be continually developed. Key areas of focus include improving accessibility and ensuring that essential information remains available on smartphones even when there is no mobile network coverage.
All alerts will be issued in standardised, machine-readable formats to enable third-party providers to integrate them into their own systems (e.g. vehicle operating systems). By expanding digital alert and information channels, the Federal Council is responding to technological developments and the widespread use of smartphones in everyday life.
Sirens, radio and emergency meeting points as important backup channels
Sirens, which are highly reliable and are installed across the cantons, will continue to be a key part of the future mix of alert channels. As with the sirens, mandatory radio announcements will also continue. These are particularly important in situations when mobile networks are unavailable or in the event of a power outage. The Swiss Broadcasting Corporation (SRG) is integrated into the FOCP’s backup systems. Since 2023, the FOCP has also been operating a system to transmit reports to private radio broadcasters. Emergency meeting points, which have now been introduced in most cantons, are another instrument that can be used to provide local information to the population in the event of a disaster.
The emergency radio system, on the other hand, will be phased out. This FM-based system, which enables radio reception in shelters, is costly to maintain. In today's expected scenarios, rapid access to information outside shelters is more important than reception within them. Even in the event of war, the FOCP expects people to stay in shelters for short periods rather than for weeks or months.
Additional funding required for 2027–2035
Between 2027 and 2035, the further development of information, warning and alerting systems will require additional funding and legal amendments. The Federal Council set the direction of the strategy in November 2024. A bill is being prepared and will be submitted to Parliament for consultation in 2026.
