SACHET: Indigenous System Powering India’s Cell Broadcast Disaster Alert Network
India’s Cell Broadcast Alert System for disaster warnings is powered by SACHET, an indigenous technology developed by C-DOT that sends instant alerts to mobile phones without any subscription.
India’s Cell Broadcast Alert System, used to send real-time disaster warnings, is powered by an indigenous technology called SACHET. This system has been developed by the Centre for Development of Telematics (C-DOT), the telecom research arm of the Government of India.
The system allows authorities to send instant alerts directly to mobile phones in an affected area. Citizens do not need to subscribe to any service or take any prior action to receive these warnings. The alerts come with loud alarm tones and flashing on-screen messages so that they are hard to miss.
SACHET supports several regional languages and can be used for many kinds of emergencies. These include natural disasters such as earthquakes, floods and tsunamis, as well as man-made threats. By reaching a large number of people within seconds, the system strengthens India’s disaster preparedness and response.
For exam aspirants, the key points are the system name SACHET and its developer C-DOT, which often appear together in science and technology and disaster-management questions.
