Radio Transmission System
Radio Transmission System
Provides radio links in the event of a disaster for the people's security.
Prefectural Disaster Prevention Radio System
- Provides radio links among prefectural government offices, municipal offices, disaster response agencies and other organizations. Also establishes a wide-area network in the prefecture.
- Communication among prefectural and municipal offices is made possible.
- With the use of a combined satellite communication and multiplex radio connections, the risk of simultaneous failure in times of disaster is decreased, thus building a more reliable communication network.
Satellite Communication System
- Deploys a communication system resistant to disasters on the ground.
- Provides communication links not only at disaster response centers but also in disaster areas by vehicle mounted earth station and transportable very small aperture terminals (VSAT).
- Provides radio links nationwide. Also exchanges information not only discretely but also simultaneously.
- Has the capacity to send telephone signals, faxes, large video files and other data.
Microwave Band Multiplex Radio Communication System
- Links between disaster response centers by microwave radio circuits and sends telephone signals, faxes, large video files and other data.
- Provides stable communication lines in the event of a disaster by using radio links that have very low possibility of cable disconnection.
Municipal Disaster Prevention Radio System
- Assists local governments to deliver disaster and administrative information to local residents.
- Configurable to suit specific purposes, including full-area and limited-area broadcasting.
- Allows to send voice data, texts and other data through the system.
- Allows personnel to communicate with each other via mobile stations.
In-tunnel Radio Retransmission Broadcast System
- Allows drivers to listen to AM and FM radio in tunnels where radio waves might normally be blocked.
- Interrupts a radio program to provide evacuation guidance via radio in the event of a traffic accident.
Weather Radar System
- Measures the intensity of rainfall over a wide area by sending microwave pulses and detecting signals reflected back from rain droplets.
- Utilizes solid-state transmitters. High-precision observation is made possible with Dual-polarization technology.
- Expected to enable the observation of rapidly developing cumulonimbus that are likely to cause tornadoes and torrential rain locally.
