The United States is introducing a new public alert system that will deliver warnings to mobile phones in the event of an emergency. The system is first being rolled out in New York and Washington and will operate nationwide by April 2012. Top mobile phone company executives joined federal officials and New York Mayor Michael Bloomberg Tuesday to announce the Personal Localized Alerting Network (PLAN). They unveiled the network at the site of the September 11, 2001 attacks on the World Trade Center. Mayor Bloomberg said the system will allow cell phone users to receive free alerts about imminent safety threats. He said it could save countless lives. The Federal Emergency Management Agency (FEMA) says the new system allows customers who own an enabled mobile device to receive the geographically targeted alerts. All major U.S. cell phone companies will participate in the system. The warnings will be localized by using local cell phone towers. The notifications could warn residents and visitors about an approaching tornado, hurricane or storm. If there is a terrorist threat, everyone in the area with a cell phone can be warned and advised what to do. The system will give priority to emergency messages, overriding all regular telephone and text traffic. The chairman of the U.S. Federal Communications Commission, Julius Genachowski, said the tragedy of September 11 taught the United States the necessity of communication technologies in times of crisis and disaster.
