[0087] In a preferred example of the present invention, in Image 6 The experiment is carried out in the indoor positioning scene shown in the figure. This scene has 3 floors in total, mainly including offices, meeting rooms, toilets, and stairs. The wireless access points have two frequency bands of 2.4G and 5G respectively. The layout positions are as follows Figure 7 shown. The number of visible APs on the first, second, and third floors were 7, 12, and 7 respectively, and a total of 955 reference points were collected, of which the numbers of reference points on the first, second, and third floors were 285, 340, and 330, respectively, and the distance between reference points was 1.2m.
[0088] Use the Huawei P20 smartphone to collect fingerprints at the reference points on each floor, and the collection software is independently developed. Collect RSSI values from only visible APs on this floor, with a sampling period of 15, and collect 60 sets of RSSI values and MA...
