Pourquoi c'est important
The Indian government is upgrading its disaster communication infrastructure to ensure reliable, real-time alerts that function independently of standard cellular network congestion.
Many mobile users across India on Saturday were caught off guard as a loud “Extremely Severe” alert flashed on their screens, triggering momentary panic before the message clarified—it was only a test.
The notification, issued by the Government of India, announced the rollout of a cell broadcast-based disaster alert system developed using indigenous technology. The system is designed to send real-time emergency warnings—ranging from natural disasters to critical public safety threats—directly to citizens’ mobile phones.
The message reassured users that no action was required, clearly stating it was a trial run.
The bilingual alert—sent in both English and Hindi—emphasised the government’s focus on strengthening disaster preparedness: “Alert citizens, safe nation.” Officials say the system will play a crucial role in ensuring last-mile connectivity during emergencies, even in areas where traditional communication channels may fail.
Unlike SMS alerts, cell broadcast messages are location-based and network-independent, meaning they can reach a large number of users simultaneously without congestion or delays.
The Department of Telecommunications, in a post on X, confirmed that the message was for testing purposes, stating, "If you receive an Alert Message on your phone, do not panic. This is part of the testing of the Emergency Alert System, so that accurate information can be received on time during disasters. During testing, this message may appear repeatedly. Ignore it; you do not need to do anything."
The Department of Telecommunications (DoT), in collaboration with the National Disaster Management Authority (NDMA), is enhancing mobile-based disaster communication systems across the country to ensure the timely dissemination of critical information to its citizens.
The system is based on the Common Alerting Protocol (CAP) as recommended by the UN body International Telecommunication Union. It is currently operational across all 36 States and Union Territories of India and delivers disaster and emergency-related alerts via SMS to mobile users within geo-targeted areas.
Cell Broadcast (CB) technology has been introduced, alongside SMS, in which alerts are transmitted to all mobile devices within a defined geographic area simultaneously, ensuring near real-time delivery of the alerts.
