How Will EWDS Work?

  • The EWDS comprises certain devices inbuilt into it like

    • Digital Mobile Radio (DMR)

    • Satellite-Based Mobile Data Voice Terminals (SBMDVT)

    • Mass Messaging System (MMS)

    • Universal Communication Interface (UCI) which help in inter-operability among different communication technologies

  • Whenever, there will be a slightest hint of a tsunami or cyclone or any other natural calamity, warning can be spread to the entire state just by the press of a button from the control room in Bhubeneswar.

  • With the press of the button, loud sirens will go off at the same time and the sound can be heard in localities to a radius of 1.5 km.

  • With this pre-warning, the EWDS will help the people to move to safer places. All these can be initiated before government agencies start evacuation

  • The protocol, which will be developed in due course of time, will help people understand the gravity of situation depending on the number of sirens that would go off from towers.
