Mizoram launches disaster communication network with 100-hour backup

Mizoram has launched a statewide emergency communication network meant to keep disaster-response agencies connected for up to 100 hours during power cuts.

Agriculture, Irrigation and Water Resources Minister P.C. Vanlalruata launched the Public Safety and Disaster Response Communication System (PSDRC) at a function in Aizawl on Wednesday, October 28.

Why it was built

The system is designed to prevent communication breakdowns among emergency responders, including the State Disaster Response Force (SDRF), police and fire services, during major disasters. Mizoram's hilly terrain makes it prone to landslides and other natural hazards, which can cut power and phone lines.

Vanlalruata stressed coordination between government agencies and voluntary organisations during disasters. He called for regular drills and training, and asked officials to keep the system well maintained and working.

Disaster Management and Rehabilitation Special Secretary Sushil Singh said the network was especially important for Mizoram. He called for close coordination between district deputy commissioners and his department so that it is used effectively.

How it works

• The main network uses a Digital Mobile Radio (DMR) Tier-III trunking system in Aizawl and DMR Tier-II conventional networks in other districts, including Kolasib and Champhai.
• A second layer running on 4G and 5G broadband adds coverage across the state.
• Both networks are integrated at the State Emergency Operation Centre (SEOC) in Aizawl, so dispatchers can talk to users on either platform and broadcast messages to both at once.
• The system records calls and tracks users by GPS, letting authorities monitor field teams during an emergency.
• Hybrid fuel-cell and solar backup keeps it running for up to 100 hours without grid power.

What it means for residents

In a disaster, responders who can talk to each other are able to reach affected areas faster and share information on blocked roads and rescue needs. The new network gives Mizoram's agencies a dedicated channel that does not depend on public mobile networks alone.
