Abstract

The invention discloses a WLAN link establishment method and device. The method comprises the steps that a first network device adopts an initial bandwidth broadcast detection request to detect whether a detection response corresponding to the detection request and sent by a second network device is received or not; if the detection response is not received, then an adjusted bandwidth broadcast detection request is adopted, and the step of detecting whether the detection response corresponding to the detection request and sent by the second network device is received or not is executed again,wherein the adjusted bandwidth refers to the bandwidth smaller than the bandwidth used last time; and if the detection response is received, a WLAN link is established with the second network device,wherein the bandwidth of the WLAN link is the bandwidth used when the detection response is received. According to the scheme provided by the WLAN link establishment method and device, under the condition that the detection response corresponding to the detection request is not received, the detection request is sent again by adopting the smaller adjusted bandwidth, so that the detection range isexpanded, and the WLAN link is successfully established.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular to a method and device for establishing a wireless local area network (Wireless Local Area Networks, WLAN) link. Background technique [0002] WLAN is a very convenient data transmission system, which refers to the application of wireless communication technology to interconnect network devices to form a network system that can communicate with each other and realize resource sharing. [0003] Before a network device establishes a WLAN link, it first searches for other network devices that can establish a WLAN link with it. In the prior art, a network device uses a bandwidth of 20 MHz to send a probe request to find other network devices with which a WLAN link can be established. [0004] Under normal circumstances, the maximum transmission distance that a probe request sent with a 20MHz bandwidth can reach is about 400 meters. If the distan...
