(一) Communication coverage and blind spots

Scenario:
When the location of the accident happens to be a blind spot of radio communication, the commander and rescuers will not be able to make immediate task assignments.

Solution:
Using the radio gateway and 4G Router on the on-site fire truck, firefighters can directly communicate with the team supervisor through the radio. Through the group in the Larzio app, the on-site firefighter, team supervisor, and fire department personnel can be added to the group and talk together.

(二) Communication between different depts

Scenario:
When a major disaster accident occurs, rescue personnel, disaster field office(DFO), and emergency response centers on the scene need to communicate and dispatch emergency response layer by layer through different communication channels, so that errors in message transmission and disaster relief time delays are prone to occur.

Solution:
A radio gateway was set up for each disaster relief team, and the commander could quickly talk with the radio of the disaster relief personnel on different channels on the scene through the group in the mobile APP.
