Abstract

An embodiment of the invention provides a scanning access point in a wireless fidelity network, a channel selecting method, a set of equipment and a system thereof. The channel selecting method comprises the following steps: determining a first channel in the WiFi network by a site according to a preset role related with a service set identification SSID of a target access point AP; and scanning by the site on the first channel so as to scann the target AP when the target AP exists and the first channel is determined and used according to the preset role. According to the scanning access point in the wireless fidelity network, the channel selecting method, the equipment and the system, because the STA determines the first channel according to the preset role, the target AP selects the channel according to the preset role, when the target AP use the first channel, the STA can scan the target AP in the first-time channel scanning, and the scanning process has pertinency, thereby greatly improving the scanning efficiency.

Description

technical field [0001] The embodiments of the present invention relate to communication technologies, and in particular to a method, device and system for scanning access points and channel selection in a wireless fidelity network. Background technique [0002] WiFi (Wireless Fidelity, Wireless Fidelity), since the release of the wireless local area network standard IEEE802.11 in 1997, under the vigorous promotion of the WiFi Alliance composed of many leading companies in the industry, with its rapid deployment, convenient use and transmission Due to the advantages of high speed and rapid development, because the current notebook computers, tablet computers and mobile phones all support WiFi technology, and users have mobile office needs, WiFi technology is widely used in various industries. The access point of the WiFi network (Access Point, referred to as AP) are found in hotels, cafes, schools, hospitals and other places. It can be said that WiFi is ubiquitous in life. ...
