Cell Broadcast

Cell Broadcasting is a function that is built into most cellular mobile systems. It allows text messages to be literally broadcast to specific geo-targeted ‘cells’, or areas in the network. Any cell broadcast-enabled cellular phone within the coverage area of these cells will receive the message. The CellAlert web portal allows an authorized message originator to select a geographic area on a map. Only those ‘cells’ that fall within the defined area will broadcast the message. Because of its geographic nature, cell broadcasting is ideal for emergency notification.

Who can receive a Cell Broadcast message?

Any one with a cell broadcast enabled mobile will be able to receive cell broadcast messages. It is possible to set up the mobile to only receive certain types of messages, e.g. weather alerts, terrorist threats, missing children etc.

What do I need to do to receive messages?

Identify your cell phone model to determine whether you need only select a feature on your phone or whether you should bring your phone to a Cell@lert authorized dealer.

How many people can receive messages?

There is no limit to how many people can receive a message; any cell broadcast enabled cellular phone within the cell broadcast area will receive the message.

Is Cell Broadcasting the same as Text Messaging?

No. SMS text messages have to be directed to specific cellular phone numbers. With cell broadcasting every cell broadcast-enabled phone in the specified geographical area receives the message. With SMS there is a significant network load when large numbers of messages are being sent, as each phone has to be addressed individually. The network loading with cell broadcasting is roughly equivalent to a SINGLE SMS message no matter how many phones are in the broadcast area.

What does it cost?

Nothing to the user.

How long does it take to send a message?

A message can be created, the geographical area defined and the broadcast started in a matter of a couple of minutes. People within the broadcast area will receive the message almost immediately. If required the message can be set to broadcast for a set time (e.g. 10 minutes) so that phones newly entering the area will also receive the message. Phones will only receive the message once.

Who is allowed to send messages?

Only properly authorized people will be able to start an emergency notification message. These will be people such as police personnel, city authorities, government agencies etc.
