The climate is changing and natural disasters like earthquakes, hurricanes, and tsunamis are increasing. In these situations, people are trapped, hurt and cannot call for help or contact rescue teams because of the telecommunication blacks-outs. Therefore, our company Crisicall is developing a robust “black boxes network” which remains connected at all times. Even when the internet and GSM connections fail. The black box establishes a WIFI hot-spot to allow people to communicate with rescue teams, take their GPS positions and get rescued every time, everywhere.
