About Cell Broadcasting system:
- It is a technology used by mobile network operators to broadcast text messages to mobile users that are located in specific geographical areas.
- The typical use for these kinds of messages is to send emergency alerts to mobile users.
- In India, it is being tested as part of the government’s broader initiative to enhance real-time dissemination of critical alerts during emergencies such as earthquakes, tsunamis, lightning strikes, and industrial hazards.
- The system is being indigenously developed by the Centre for Development of Telematics (C-DOT).
- Unlike SMS alerts, CB messages are broadcast to all mobile phones in a specific area, ensuring rapid delivery even in congested networks.
- The technology enables alerts to reach citizens almost instantly, making it highly effective during time-sensitive disasters.
- This new system is in addition to the already-operational Integrated Alert System (SACHET), which has delivered over 6,899 crore SMS alerts in more than 19 Indian languages across all 36 States and Union Territories.
- SACHET is based on the Common Alerting Protocol (CAP), as recommended by the International Telecommunication Union (ITU).
- Once fully operational, the CB system will broadcast alerts in multiple Indian languages to all mobile users, ensuring broad and inclusive public reach.
