1. , in a wireless local area network for detecting a method for the existence of unwarranted equipment, the method comprises:

  • Detection can send the existence of each equipment of management frames from it;

    Preserve the expression of individual signal strength signal intensity as described each equipment of each determination in the expression of the neighbouring device of described each equipment and described neighbouring device, wherein said each equipment is labeled according to the signal strength signal intensity of each neighbouring device being received from this equipment;

    Receive the management frames declared from one of the equipment detected, this management frames comprises signal strength signal intensity instruction and device identifier;

    Described device identifier from described management frames is mated with one of described neighbouring device;

    By the signal strength signal intensity instruction from the described management frames received compared with the signal strength signal intensity of the determination of the neighbouring device of coupling;

    If the difference of described signal strength signal intensity instruction and the described signal strength signal intensity determined is greater than threshold quantity, then determine that received management frames is sent by unwarranted equipment;

    AndIndicate the existence of described unwarranted equipment.
