Demonstrates the signal level, which is obtained from four access points. It indicates that different signals from different access points show different patterns of data. According to the signal from the access point, number 1 has a peak signal at point 15, which is assigned to be the point (0,0). The signal from the second access point has a peak signal at point number 0, identified by (0,18) in the coordinate system. The third and the fourth access points have the highest signals at point number 55(30,18) and point number 40(30,0), respectively. The clear differences in the signal pattern support the model of the KNN algorithm.
