Abstract
This paper describes the current National Weather Service's (NWS) system for providing weather alerts in the U.S. and will review how the existing end-to-end architecture is being leveraged to provide non-weather also known as alerts, to the general public. The paper then describes how a legacy system that transmits weather and all-hazard alerts can be extended via commercial wireless networks and protocols to reach 154 million Americans who carry cell phones. This approach uses commercial SATCOM and existing wireless carriers and services such as Short Messaging Service (SMS) for text and emerging Multimedia Messaging Service (MMS) protocol, which would allow for photos, maps, audio and video alerts to be sent to end users. This wireless broadcast alert delivery architecture is designed to be open and to embrace the National Weather Service's mandate to become an warning system for the general public. Examples of other public and private sector applications that require timely and intelligent push mechanisms using this alert dissemination approach are also given.
