1. A spectrum sharing method for a DYSPAN system comprising:

  • performing channel evaluations and channel selections to detect and select spectrum holes;

    verifying if non-exclusive sharing of selected channels is feasible;

    if non-exclusive sharing of the selected channels is feasible, making a DFS decision and scheduling data transmissions on the selected channels with appropriate TPC settings;

    if non-exclusive sharing is unfeasible, performing exclusive sharing of the selected channels;

    if the selected spectrum hole is not occupied by a specific type of DYSPAN system, then performing data transmissions without using the selected channels if possible; and

    if the selected spectrum hole is occupied by a specific type of DYSPAN system, initiating a spectrum contention process for ownership of the selected channels.
