Abstract
In one general aspect, a communications system as described herein provides a wide-band jamming signal that is digitally created, conditioned, and modified by a processing based system to provide open data channels to authorized parties within a jammed communications band. The communications system modifies and maintains the open data channels to sustain communications between authorized devices. In addition, the communications system provides frequency hopping using the open data channels to supply secure data links to authorized devices within the jammed communications band while denying service to unauthorized communication nodes or devices.
