Converting a cell phone into a cell tower The project includes two systems that can operate separately or be combined. One is specifically for disaster areas, and consists of a temporary, self-organizing and self-powered mobile phone network that operates via small phone towers dropped into the area by aircraft.The second system consists of a permanent mesh-based phone network between Wi-Fi enabled mobile phones, with no tower infrastructure required. It incorporates a compact version of a mobile phone tower into the phone itself, using the Wi-Fi interface in Wi-Fi-enabled phones.The current range between phones is only a few hundred meters, which limits the usefulness of the system in remote areas, but adding small transmitters and more devices could expand the range considerably.
