1. A method for allocating traffic between multiple carriers in a wireless communications system, the system including at least a first carrier within a first frequency spectrum and serving a geographic region and a second carrier within a second frequency spectrum different from the first frequency spectrum and serving the geographic region, the method comprising:

  • determining a threshold based upon differential electromagnetic interference measured within the second frequency spectrum relative to the first frequency spectrum in the geographic region, the threshold ranging from a maximum at a highest measured differential interference to a minimum at a lowest measured differential interference;

    prohibiting inter-carrier hand-offs between the first carrier and the second carrier at the maximum; and

    allowing inter-carrier hand-offs below the maximum.
