Cell broadcasting is a mobile network technology that allows operators to send text messages to multiple users within an area. For example, you have a cell phone and you want to keep up to date on the weather, you can subscribe to a weather forecast service that you receive on a regular basis via SMS.

Please let me know what if this makes sense.
Thanks,
Torsten
