About EWBS

What is EWBS?

The Emergency Warning Broadcasting System (EWBS) is a system that transmits emergency disaster information via broadcast waves when a natural disaster occurs such as earthquake and tsunami.
To transmit emergency disaster information, it requires for anyone to receive reliable information anytime, anywhere.
The terrestrial broadcasting waves have five technologically superior features that meet these requirements.

Terrestrial broadcasting of TV and radio are operated as a public medium for transmitting information in every country in the world.
By leveraging existing terrestrial broadcasting infrastructure, you can deploy EWBS easily and cost-effectively.


Wide Coverage: Because terrestrial broadcasting is a public service, it covers most countries and a large portion of their landmass.
The coverage of EWBS aligns with the existing broadcasting wave coverage because it utilizes these waves.


Robust Transmission and Reception: Broadcasting facilities are constructed to be highly robust so that radio waves will not be interrupted, enabling stable and sustainable operation even during disaster.
In addition, broadcasting radio waves have strong reception characteristics, and with digital technology (one-segment broadcasting), reception is possible even in vehicles and vessels.


One-way Communication: One-way communication is not affected by IP transmission traffic concentration, cyber-attacks, etc., and can be operated stably and reliably even during emergencies.


Rapid transmission (Low Latency): As broadcast radio waves facilitate one-way communication, there is very little latency loss in the transmission path.


Simple and Low-cost Introduction: The EWBS system can be easily and cost-effectively introduced by leveraging existing infrastructure to the maximum extent.
There is no need to build a new transmission station because EWBS is simply multiplexed into the broadcasting radio wave.
