Abstract

The embodiment of the invention provides a wireless channel switching method and a wireless channel switching device. The method provided by the embodiment of the invention comprises the steps of acquiring channel state information of each candidate channel; acquiring sub-carrier difference data of each candidate channel according to the channel state information of the candidate channel based on each candidate channel; and thus switching a wireless channel according to the sub-carrier difference data of each candidate channel. Therefore, according to the technical scheme of the method and the device provided by the embodiment of the invention, the problem that in the prior art, channel switching is relatively low in accuracy when channel switching is completed through depending on an RSSI in an indoor environment is solved.

Description

【Technical field】 [0001] The present invention relates to the field of wireless communication technologies, and in particular, to a method and device for switching wireless channels. 【Background technique】 [0002] In recent years, Wireless Fidelity (Wireless Fidelity, Wi-Fi) technology has developed rapidly and has become a mainstream technology in an indoor communication environment. As a main technology of wireless network, Wi-Fi has more and more application scenarios due to its convenience, flexibility and low equipment overhead. The Internet is everywhere in the home, school, office or mall. [0003] With the substantial increase in the number of wireless users, the interference in the communication environment increases, which affects the performance of the wireless network. In order to avoid the influence of interference, in China, the wireless access point of the Wi-Fi operating frequency of 2.4GHz provides 13 channels, A Wi-Fi access point with a frequency of 5GH...
