1. A communications system for jamming radio frequency (RF) communications of an unauthorized device within a broadband frequency spectrum within a jammed area, the system comprising:

  • a control node including a processor to determine RF channel information for at least one communications channel within the broadband frequency spectrum;

    at least one authorized jamming node to transmit RF signals to jam RF communications within the broadband frequency spectrum and to create notches within the broadband frequency spectrum clear of RF energy corresponding to said communications channel based on said RF channel information; and

    at least one communications device authorized by said control node to communicate using said communications channel located within said notches, wherein said communications channel includes a caretaker channel to provide synchronization data and said channel information to authorized jamming nodes and communications devices.
