The company said the unit requires external power to work and can be used to set up a cell site in less than 30 minutes.
AT&T Business Solutions Advanced Mobility Solutions vice-president Chris Hill said, "In the pivotal first minutes of a natural or man-made disaster, AT&T Remote Mobility Zone provides a solution to help maintain critical mobile communications."
Hill added, "With AT&T Remote Mobility Zone, users can set up a cell site in less than 30 minutes."
The Remote Mobility Zone can handle 14 simultaneous calls, and data at less-than-broadband speeds. Coverage extends up to half a mile from the unit.
