1. A method for use in allowing a wireless receiver to avoid interference from a potentially interfering transmitter, the method comprising:

  • (a) determining whether a signal from the potentially interfering transmitter is operating at essentially the same carrier frequency as an expected signal at an assigned carrier frequency;

    (b) determining whether a predicted carrier to interference noise ratio of the receiver will exceed a predetermined level based on the greater of an instantaneous carrier signal strength and an average carrier signal strength; and

    (c) if so, causing the receiver to switch to another carrier frequency to receive the expected signal.
