Emergency Communication When Networks Fail
Mobile networks fail first in a crisis — congestion or power loss at cell sites. The plan: reception-independent information (radio) and a family communication plan that works offline.
Emergency radio = basic equipment
A crank or battery radio receives FM/AM broadcasts even during total blackout. Digital DAB+ radios fail when transmitter power fails; analog FM is more robust.
Smartphone as emergency device
Activate power-saving mode early. Important numbers also on paper. Offline maps (OSM-based) of your region already downloaded.
Family communication plan
Agree on a distant relative as a hub person — in regional outages, long-distance calls often work. SMS gets through before calls when networks are congested.
When everything fails
Battery or wind-up radios remain the last resort. For the ambitious: amateur radio (license-free variants exist) reaches beyond any network.
Inform sources offline
Note local emergency stations and authority websites now — during the crisis you won't want to research.
