1. A method for dynamically managing Secondary User Node (“

  • SUN”

    ) access to a segment of a wireless spectrum licensed for use by Primary User Nodes (“

    PUNs”

    ), the method comprising;

    detecting, by first and second SUNs, physical data transfers by the PUNs at a plurality of first licensed frequencies during a plurality of slot sample times of a first epoch;

    generating, by each of the first and second SUNs, a report comprising sensed spectral data indicating(1) during which of the slot sample times each physical data transfer was detected by a respective one of the first and second SUNs, and(2) at which of the first licensed frequencies each physical data transfer occurred;

    receiving, by the first SUN, the report broadcasted from the second SUN at a non-licensed frequency during a respective one of a plurality of slot report times following the slot sample times of the first epoch; and

    analyzing, by at least the first SUN, the sensed spectral data of the reports to determine a time for using a first licensed frequency without interfering with or only minimally interfering with use thereof by the PUNs.
