Software enables cell phones to communicate where there is no reception
According to ABC News, Australian researchers have developed software that allows mobile phones to communicate with each other where there is no reception.
It is a new mobile phone system that promises to work anywhere and potentially help save lives in a disaster.
Researchers have gone to extraordinary lengths to test it out in a remote desert wilderness in South Australia.
... Dr Paul Gardner-Stephen, who is leading the project, has made software that allows ordinary mobiles to communicate without phone towers or satellites. He says his device actually incorporates a compact version of a mobile phone tower into the phone itself.
"So using the WiFi interface that is in many phones today that you would normally use for internet or that kind of thing, we are actually carrying voice over that, but in a way that doesn't need to go back to a central repository anywhere," he said.
The signal between phones is limited to a few hundred metres but by adding more devices and small transmitters the range can be expanded to cover a much bigger area.
Dr Gardner-Stephen says the system could provide an instant mobile phone network in a disaster.
