Pan-India Testing of Indigenous Cell Broadcast System Underway for Rapid Disaster Alerts

• Cell Broadcast System (CBS) — an indigenous emergency alert technology developed by C-DOT under the Department of Telecommunications (DoT) that pushes geo-targeted alerts simultaneously to all mobile phones in a defined area.
• Operates alongside the CAP-based SACHET platform run by NDMA, marking a shift from SMS-only alerts to near-real-time broadcast in tsunamis, earthquakes, lightning, gas leaks, etc..
• Relevant for Prelims (S&T + disaster bodies) and GS-III Mains (Disaster Management, Indigenous Tech).
