Cell Broadcast System (CBS) Launched — India's Indigenous Emergency Alert Platform

📌 Summary:

• India launched the Cell Broadcast System (CBS), an indigenous emergency alert technology developed by C-DOT (Centre for Development of Telematics) under DoT, in collaboration with NDMA and MHA

• CBS is a telecom-enabled public warning system that broadcasts simultaneous, geo-targeted alerts to all mobile devices within a defined area — integrated with the CAP-based SACHET platform

• Unlike traditional SMS-based alerts, CBS overcomes network congestion limitations and delivers alerts in near real-time (within seconds), without queuing delays

• Precise geo-targeting at individual cell tower/cluster level; can scale to cover larger geographic areas; alerts cannot be disabled by users

• Universal reach: covers all mobile users including roamers across 2G–5G networks, ensuring last-mile and rural coverage; supports multilingual alerts

• Nationwide test successfully conducted on May 2, 2026 — emergency alerts broadcast across the country with distinctive loud tones and pop-up notifications

• Pan-India trials completed; system proven effective in Andhra Pradesh, Odisha and Uttarakhand disasters; also used for Char Dham Yatra

• C-DOT has demonstrated CBS internationally in Mauritius, Cambodia, El Salvador and Sri Lanka; aligns with the UN "Early Warnings for All" initiative

• Subhash Chandra Bose Aapda Prabandhan Puraskar (SCBAPP) also awarded at the event; Disaster Management Guidelines and Handbook released
