Australian scientists successfully created an antenna that can support mobile communication in areas that have absolutely no telecommunications signals.This antenna was small enough and integrated in the phone. With this antenna, the phone can be connected to each other via wifi signal, and allows the formation of the network itself.
Researchers from the University of South Australia Flinder create this phone to function in areas that are affected or the area where the cellular signal had been blocked.
Professor named Paul Gardiner, Stephen verify if the device has been tested in a remote region in Australia, where cellular signals are not available.
'There was absolutely no infrastructure or support for mobile phones so they must find a way to make calls, he said.
This phone is not possible to replace the existing cellular systems in a mobile phone but existing technologies can be combined to create a backup communications.
"One of our dreams, each phone will technology like this someday, so if there is a disaster anywhere, all the phones in the world will switch to this system as a backup," said Gardiner.
"If infrastructure is damaged and the existing telephone network is not capable of providing services, we are still providing good service," said Gardiner.
At this time, the signal between the phone is limited to distances of several hundred meters, but the team of scientists is hoping to expand cellular coverage in the future.
