Proposed emergency communications system borrows neighborhood Wi-Fi connections


During a major distaster, cellular signals can become flooded by high call volumes, but German scientists are testing a method of linking household routers to provide emergency teams with a backup communications system. According to Security Week, a team from the Technical University in Darmstadt, Germany scanned the density of their city to see just how affective the technique would be, locating almost 2,000 routers in only half a square kilometer. With a population of 142,000, Darmstadt is smaller than many metropolitan areas, so implementing a similar system in a major city would theoretically provide an extremely robust web of internet access.

To utilize the service, routers would include a special channel that could only be accessed…
