Abstract: Embodiments of the present invention provide an access point handover method and an apparatus. The method includes: sensing, by a terminal, that a currently connected access point cannot satisfy a transmission condition. The method includes finding, by the terminal, that at least one access point satisfying the transmission condition exists in access points having names partially the same as that of the currently connected access point. The method includes establishing, by the terminal, a connection to one of the at least one access point satisfying the transmission condition.

Abstract: A mode switching method in a WI-FI network includes after a terminal device accesses a WI-FI network, the terminal device communicates, in a multiple-input multiple-output (MIMO) mode, with an access point that provides an access service of the WI-FI network. The terminal device obtains first received signal strength and a first throughput of the WI-FI network in the MIMO mode, and when the first received signal strength is greater than a first strength threshold and the first throughput is less than a first throughput threshold, the terminal device switches from the MIMO mode to the single-input single-output (SISO) mode.

Abstract: A wireless communication system includes a first terminal and a routing device. The routing device is configured to perform channel availability check (CAC) before performing communication on a 5 gigahertz (GHz) channel of a first frequency bandwidth, and broadcast a beacon frame on the 5 GHz channel of the first frequency bandwidth when the routing device does not detect a radar signal. The routing device is configured to operate on the 5 GHz channel of the first frequency bandwidth, and the first frequency bandwidth includes a dynamic frequency selection DFS channel. The first terminal is configured to perform communication on the 5 GHz channel of the first frequency bandwidth when the first terminal is configured to operate on the 5 GHz channel of the first frequency bandwidth and receives the beacon frame on the DFS channel.

Abstract: Embodiments of this application provide an information obtaining method and a terminal device. The method is applicable to a device having a wireless fidelity Wi-Fi function. When the terminal device cannot be connected to a cellular network, the method includes: The terminal device configures at least one first channel and a transmit power of each first channel, searches for an access point device on a corresponding first channel by using a configured transmit power, completes an access connection to a found access point device, obtains a current geographic location of the terminal device based on a media access control MAC address of the access point device connected by the terminal device, and obtains country information (for example, a country code) based on the geographic location. Alternatively, the terminal device locates a current geographic location of the terminal device by using a built-in positioning module, and obtains corresponding country information (for example, a country code) based on the geographic location, so that the terminal device subsequently configures a correct transmit power and a correct channel for Wi-Fi based on the country code.
