Embodiment approach
[0052] This embodiment provides an implementation manner for a positioning server to obtain a reference fingerprint feature vector, which specifically includes:
[0053] Step 201: The positioning server sends a second positioning indication message to one or more APs through the AC, so that the one or more APs can collect the RSSI of the test equipment located at the specified location, where the second positioning indication message includes the test equipment The identification of and the location coordinates of the specified location;
[0054] Among them, this embodiment is still implemented based on the radio frequency fingerprint positioning system in the foregoing embodiment. The second positioning instruction message is a positioning instruction message sent by the positioning server to the AP to obtain the reference fingerprint feature vector corresponding to each positioning point in the positioning system. The positioning instruction message includes the identification o...
