Embodiments of this application disclose a group-based calibration method and device. The method includes: A control device that obtains path loss data of a wireless access point AP set, where the AP set includes a plurality of APs, and the path loss data includes a path loss between any two of the plurality of APs. The control device obtains a first calibration group based on the path loss data, and sends first calibration information to a management AP of the first calibration group, where the management AP of the first calibration group is an AP that performs calibration management in the first calibration group. By implementing the foregoing method, the control device may divide a plurality of APs into a plurality of calibration groups based on path loss data between the APs, to decrease a coupling degree between the calibration groups.

An obstacle recognition method and apparatus, and a related device are provided. The method includes: obtaining an actual path loss value between a first AP and a second AP, path loss value pairs between a terminal and a plurality of AP pairs, and path loss values of the plurality of AP pairs; obtaining, based on the path loss value pairs between the terminal and the plurality of AP pairs, an AP pair similar to an AP pair formed by the first AP and the second AP; obtaining a second path loss value between the first AP and the second AP based on a path loss value of the similar AP pair; and comparing the second path loss value between the first AP and the second AP with the actual path loss value, to determine whether an obstacle exists between the first AP and the second AP.

Embodiments of this application disclose a radio frequency resource allocation method, apparatus, device, system, and a storage medium. The method includes: obtaining radio frequency information of an access point AP (for example, RSSI signal strength between the AP and each neighboring AP, and data traffic of the AP in a data collection period), predicting, based on the radio frequency information of the AP, load of the AP that is in target duration after a current moment, and allocating a radio frequency resource to the AP based on the load of the AP. This implementation can reduce actual interference on an entire network and improve user experience.

This application discloses a terminal roaming method and apparatus. A terminal sends, to a first AP associated with the terminal, an action frame that is used to request to associate with a second AP. A receiver address of the action frame is an address of the first AP, and the action frame further includes an identifier of the second AP. When the terminal receives a response frame sent by the first AP for the action frame, and the response frame indicates that association succeeds, the terminal establishes association with the second AP. The terminal first establishes the association with the second AP by using the first AP, and then changes an operating channel to an operating channel of the second AP. Now the terminal can receive and send data on the operating channel of the second AP.

In a terminal roaming steering method, a steering protocol supported by a terminal and a second AP are determined, and the terminal is steered, based on the steering protocol supported by the terminal, to roam from a first AP to the second AP.

Example methods, apparatuses, and systems for transmitting data in a wireless local area network mesh network are described herein. One example method includes receiving, by a first mesh station, a first data frame sent by a second mesh station, where a transmitter address of the first data frame is a MAC address of the second mesh station, and wherein the first and second mesh stations belong to different mesh gates. The first mesh station determines that the first data frame is one of a broadcast data frame, a multicast data frame, or an unknown unicast data frame and, further, that the first mesh station and the second mesh station belong to different mesh gates. In response to these determinations, the first data frame is discarded. The examples methods can be applied to a wireless mesh network including multiple mesh gates.
