1. A wireless access point (AP) group-based calibration method comprising:
obtaining, by a control device, path loss data of a wireless AP set, wherein the AP set comprises a plurality of APs, and the path loss data comprises a path loss between any two of the plurality of APs;
obtaining, by the control device, a first calibration group based on the path loss data, wherein the first calibration group comprises a first AP and a second AP of the plurality of APs, wherein the obtaining the path loss data of the AP set comprises:
obtaining, by the control device, first path loss data, wherein the first path loss data is a path loss value between the first AP and the second AP that falls within a preset range and that is obtained at a third sampling moment;
obtaining, by the control device, second path loss data, wherein the second path loss data is a path loss value between the first AP and the second AP that falls within the preset range and that is obtained at a fourth sampling moment; and
obtaining, by the control device, path loss data between the first AP and the second AP based on the first path loss data and the second path loss data; and
sending, by the control device, first calibration information to a management AP of the first calibration group, wherein the first calibration information comprises an identifier of the first AP, an identifier of the second AP, and calibration sequence information for the management AP of the first calibration group to determine a calibration starting moment based on the calibration sequence information, and wherein the management AP of the first calibration group is an AP that performs calibration management in the first calibration group.
