Announcement & Broadcast Systems
National Early Warning Systems
Japan's national early warning system (J-ALERT), to which NEC contributed as a system suppliers, transmits high-priority emergency information, such as earthquake early warnings, tsunami information and armed attack information, from the Fire and Disaster Management Agency (FDMA) via satellite to provincial or city authorities. The information is then distributed to residents using the disaster prevention radio system.
Disaster Prevention Radio Broadcast Systems
NEC's municipality disaster prevention radio system broadcasts alerts throughout the city. The system consists of a master station, repeater stations, mobile stations, outdoor loudspeaker sites and household receivers.
