In the case of any natural calamity, we have a smartphone, which often leads us out of trouble. But in most cases (in situations like earthquake, flooding, landslide), communication services are completely damaged. Due to which it takes time to reach people stranded in trouble.   

Considering such emergency situations, scientists have developed a smartphone app, with the help of which there is no signal in the mobile, the affected people can be reached in an emergency and they can be saved.   

This app can save your life. The U.A. (Universidad de Alicante) in Spain has made an app that can be used in emergency situations like flood, earthquake, fire. When all communication communications are interrupted. 

In case there are no mobile signals during trouble, scientists have developed an app that will immerse the WiFi signal without the presence of no signal, through which the rescue teams can easily reach the people trapped in disaster.

The location coordinates of the trapped person will be present in these signals coming out of the smartphone. Through which they can be easily found. With a signal, a small message can also be sent through the app to help the person trapped in difficulties. To identify these signals, scientists created a portable device through which these signals could be decoded.
