Definition: A cell broadcast 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.
A Cell Broadcast explained
SMS is commonly used for sending out public and private notices. However, for public warnings and messages, Cell Broadcast (CB) is a far more effective system. Cell Broadcast appears like a text message and is transmitted by a mobile mast. The message might be sent from a single mobile mast or from all of the mobile masts in the country. Anyone in the area or passing through the area will receive the messages, even if the signal is weak.
As digital transformation has accelerated, governments are now aware that traditional emergency methods such as radio, television, and sirens are no longer adequate. As a result, authorities have turned to technology such as Cell Broadcast to raise the alert - the most appropriate device for relaying this information is the mobile phone. The mobile phone, being one of the most widely used communication channels in the world, can take a text message and communicate the level of detail essential to help individuals take action and preserve safety.
The advantage of a Cell Broadcast service is that users can receive messages without the need for any subscriptions, and they do not have to provide personal information such as phone numbers or location data, the only thing required is to have a phone switched on. Moreover, the system remains unaffected by network congestion, enabling instantaneous delivery of messages to millions of people at once, and providing them with relevant information and guidance.
Cell Broadcast is already activated on the latest mobile devices. For other operating systems and older Android versions, the user may need to contact their network provider or device manufacturer to activate the Cell Broadcast service.
