New Smartphone App to Help Locate People in Areas Without Network
HIGHLIGHTS
- The app was developed by researchers in Spain
- It’s intended to help discover stranded people amid a crisis
- Application influences the phone to radiate a Wi-Fi signal that can be detected
Analysts of the Universidad de Alicante (UA) have grown new innovation that makes it conceivable to locate people who have endured an accident in remote areas without a phone signal and where a speed rescue is essential to spare lives. The system can likewise be utilized as a part of emergency situation that emerge because of earthquakes, floods or forest fires, where mobile phone infrastructure is frequently rendered useless.
“We have designed an application (app) that can be incorporated to any smartphone and that, without a signal, emits a Wi-Fi signal which in turn acts as a distress beacon over a distance of several kilometres,” said Jose Angel Berna, creator of the technology and professor at UA.
This signal contains the area (coordinates) of the individual who has endured the accident or vanished and is utilizing the smart phone producer, alongside a short message that “can be altered relying upon the situation, for example, “I am injured,” “I am disorientated,” or “I need help”, determines Berná.
With a specific end goal to recognize the distress signal, the researchers have additionally made a light, portable receptor gadget that rescue teams or mountain shelters could use.
This gadget has a small antenna and interfaces with the smartphone of the search party. At the point when a accident happens, the victim just needs to activate the mobile phone application, which will, in turn, transmit the distress signal occasionally – for quite a long time or even days, regardless of whether they are oblivious – demonstrating the directions of its area.
Amid the tests performed on ground and ocean it was affirmed that the gadget can get the distress signal of the radiating smartphone up to a separation of a two or three kilometers, individually, in spite of the fact that it might be conceivable to increase its reach, researches 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 €80,000 and requires the use of a helicopter,” says José Ángel Berná. However, the system developed in the UA is more economical, “as its receptor has a cost that would allow its commercialisation for approximately €600 if used by a large number of rescue teams,” he adds.
