Abstract: This application relates to the field of communications technologies, and provides a mode switching method in a Wi-Fi network and a terminal device, to reduce power consumption of the terminal device while implementing a MIMO function. The method 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: Embodiments of the present invention provide a hotspot scanning method and an electronic device. Whether a condition of initiating a hidden hotspot scanning is met is first determined. If the condition of initiating the hidden hotspot scanning is met, a name of a hidden hotspot is obtained. Then, the hidden hotspot scanning is initiated by using the name of the hidden hotspot. If the condition of initiating the hidden hotspot scanning is not met, the hidden hotspot scanning is not initiated. In this way, whether the condition of initiating the hidden hotspot scanning is met is determined before the hidden hotspot scanning is initiated. This effectively reduces a disclosure probability of the name of the hidden hotspot, thereby achieving a purpose of reducing a security risk in hotspot scanning.

Abstract: An antenna selection method and a terminal, where the terminal includes m primary antennas configured for a first application program and n secondary antennas, where m≥1, and n≥1. The method includes, when the terminal is in a WI-FI connected state and a landscape state, obtaining a key factor and a radio frequency indicator that are of each of m+n antenna combinations, determining a first antenna combination based on the key factor and the radio frequency indicator, where the first antenna combination is a first-priority antenna combination of the m+n antenna combinations, and the first antenna combination includes at least one of the secondary antennas, and using the first antenna combination to perform communication for a second application program.

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.
