    Step 2: when the difference between the AP quantity k in n and the first AP set is not 0, appointing in n-k AP is selected Anticipate f AP, wherein, f is the natural number less than or equal to n-k；
    Step 3: in the f AP gathers with the first AP respectively each secondary signal intensity of AP between any two difference When value is both less than second threshold, the second letters of each AP between any two in being gathered respectively with the first AP according to the f AP Number f AP described in the Strength co-mputation each distances of AP between any two in gathering respectively with the first AP；According to the f AP points The each distances of AP between any two in not gathering with the first AP, the position of the f AP is determined using least square method；
    Step 4: the f AP is added in the first AP set, the value of the k adds f；
    Step 2 is repeated to step 4 until the condition of triggering setting.
