Saved by the WiFi smartphone!

This is what could soon read the headlines, with this simple but clever use of WiFi smartphones.

Did you know? 

The vast majority of smartphones can act as access points, that is to say, share a data connection with other devices via a wireless link. But this feature can also be exploited to send short messages.

The trigger would come from neighboring (perhaps a bit grumpy) who use their Hotspot WiFi to broadcast short messages such as "no smoking on the balcony" or "make less noise." From there came the idea that Wifi Hotspot could also be used to disseminate SOS disaster.

There is magic is that during natural disasters, traditional telecommunication networks are often cut off or saturated: Unable to send an SMS or an e-mail. WiFi and radio waves do not require anything other than a smartphone and a good battery.

Project

The project is very serious. Al-Akkad, an engineer, wants to exploit this functionality via apps, so that after a disaster, it is easier for rescue teams find people in trouble.

The team that is behind this initiative have already consulted rescuers who worked Fukushima Haiti and for the development of the "victim app" and "app seeker." One is for the victims and for other researchers. With this solution, the victims can easily write short messages of 27 characters such as "fire need assistance 4 etc. " If a smartphone with a "seeker app" is 100 meters, the message is detected.

A simulated terrorist attack has already been made in Norway, led by Sintef organization. The device has 2 find people trapped. Currently, the project proponents would like the application to be inserted in the Android and iOS operating systems.

Simple but useful


Remember, if you want to broadcast a message to your neighbors or disaster, you can use this system D by activating the WiFi hotspot on your smartphone (or your computer) and by the small message on behalf of the connection, do not forget to make the connection available for all devices. This can still be used.
