Researchers develop an app to locate people in areas without network during emergency situations

With advancements in technology and continuous innovation in mobile technology, scientists have now developed a smartphone app that can be used in emergency situations arising due to earthquakes, floods or forest fires. The main highlight of this app though is that this app will work even where mobile phone infrastructure is often rendered useless.

This new app will help locate people in areas without network

The system has been created by researchers at the Universidad de Alicante (UA) in Spain and this new tech makes it possible to locate people who have suffered an accident in remote locations without a phone signal and where a speedy rescue is essential to save lives.

“We have designed an application (app) that can be incorporated to any smartphone and that, without a signal, emits a Wifi signal which in turn acts as a distress beacon over a distance of several kilometers,” said Jose Angel Berna, creator of the technology and professor at UA.

Further, “this signal will contain the location (coordinates) of the person who has suffered the accident or disappeared and is using the smartphone emitter, along with a short message that can be altered depending on the situation, with examples such as “I am injured,” “I am disorientated,” or “I need help,” said Berna.

In order to detect the distress signal, researchers have created a light, portable receptor device that rescue teams or mountain shelters can use. Talking about this device, it has a small antenna and connects to the smartphone of the search party. When an accident occurs, the victim only has to activate the mobile phone app, which will, in turn, emit the distress signal periodically – for hours or even days, even if they are unconscious – indicating the coordinates of its location.

During the tests performed on ground and sea it was confirmed that the device can pick up the distress signal of the emitting smartphone up to a distance of two or three kilometers, respectively, although it may be possible to increase its reach, researchers said.

“At present, there is no system in the world that uses Wi-fi signals to geo-locate a smartphone. There are devices that allow you to detect mobile phone signals from a smartphone and pinpoint its location through triangulation, but it costs around EUR 80,000 (roughly Rs. 61 lakhs) and requires the use of a helicopter,” said Berna.

However, the new system is more economical, “as its receptor has a cost that would allow its commercialization for approximately EUR 600 (roughly Rs. 45,983) if used by a large number of rescue teams,” he added.
