Why in the News?

The Cell Broadcast Alert System (CBAS) of the National Disaster Management Authority (NDMA) did not effectively disseminate mass alerts during natural disasters, despite recent testing.

About Cell Broadcast Alert System (CBAS):

  • The Cell Broadcast Alert System (CBAS) is a public warning system that uses mobile networks to send emergency alerts to mobile phones within a specific geographic area.
  • It is a one-way messaging system that allows authorized authorities to send short messages to all mobile phones within a designated area, regardless of whether the recipients are subscribed to the mobile network or not.

Benefits of CBAS:

  • Rapid and widespread dissemination of information: CBAS can reach a large number of people within a short period of time, making it an effective tool for communicating critical information during emergencies.
  • No user interaction required: CBAS messages are automatically displayed on mobile phones, so there is no need for users to take any action to receive them.
  • Effective for reaching all mobile phone users: CBAS messages can be received by all mobile phone users, regardless of whether they are subscribed to a particular mobile network or not.
  • Not affected by network congestion: CBAS messages are not affected by network congestion, so they can be delivered even when network traffic is heavy.

CBAS can be used to send a variety of emergency alerts, including:

  • Weather warnings: CBAS can be used to warn people of impending severe weather, such as tornadoes, hurricanes, and flash floods.
  • Amber Alerts: CBAS can be used to broadcast information about missing children.
  • Public safety alerts: CBAS can be used to warn people of other public safety threats, such as fires, terrorist attacks, and chemical spills.
