Abstract
A method and system for local broadcasting of messages from a wireless mobile device to many others located within the same geographic area. This can be done using SMS messaging wherein a message to be broadcast is addressed to a particular designated address and, when received by a wireless carrier system, is checked to determine that it came from an authorized sender, and then is broadcasted by the wireless carrier system to a geographically-limited area within which the sending wireless mobile device is located.
