Overview

• The tests will take place on Thursday, March 13, in states including Bavaria, North Rhine-Westphalia, Hesse, and Rhineland-Palatinate.
• Warning systems being tested include sirens, the Cell Broadcast system, and apps like NINA and Katwarn, alongside other communication channels such as radio and digital signage.
• The Cell Broadcast system delivers emergency alerts directly to mobile phones without requiring an app, enhancing reach during crises.
• Officials aim to assess the functionality of the systems, identify improvements, and educate the public on recognizing and responding to alerts.
• Several regions have recently upgraded or expanded their siren networks, with new installations designed to operate during power outages and enable voice announcements.
