Therefore, for users, if they need to use a channel with 40M bandwidth, the user has two options. The first option is to use 40M+ automatic channel selection, and the other option is to use 40M-automatic channel selection, but when the current best channel When it is the 11th channel, and the user chooses to use 40M+ automatic channel selection, the best channel cannot be used, and the user needs to re-select to use 40M-automatic channel selection to select the current best channel, which is the channel with the serial number 11 , and vice versa, such routers bring inconvenience to users, because they do not know in advance which channel is the best, when users choose to use 40M+ automatic channel selection or 40M-automatic channel selection, they can only select Automatically select the best channel among the 9 channels to use, that is to say, the user may not be able to use the best channel after choosing to use 40M+ automatic channel selection or 40M-automatic channel selection, and can only use the selected 1~9 A total of 9 channels or the best channel among a total of 9 channels from 5 to 13 will damage the interests of users

Embodiment 1
[0015] Embodiment 1, this embodiment is a method for a wireless router to select the best channel, such as figure 1 As shown, this method realizes the best channel selection, and makes the working channel of the wireless router fixed on the best channel.
[0016] When it is detected that the user selects the 40M automatic channel selection option, the following steps are included:
[0017] Step 1. The system enters the 20M automatic channel selection mode. At present, the 20M automatic channel selection method can be selected from 13 channels at the same time, and the center frequency of the 20M bandwidth and the 40M bandwidth basically coincide, but the bandwidth is different, so when the 20M bandwidth is the best channel quality frequency band, in 40M Bandwidth is also the best frequency band, therefore, the sequence number of the best channel selected by the 20M automatic channel selection method is also the sequence number of the best channel when the bandwidth is 40M.

The invention provides a method for automatic channel selection. The method comprises the steps that after a 40M automatic channel selection option is issued for a user, a system firstly sets the band width as 20M, the 20M band width has no conceptions of 20M+ or 20M-, and the range of the automatic channel selection is a 1-13 full range. After the optimal channel n is obtained under the 20M band width, the channel is set back to be a band width of 40M- or 40M+, and finally, the channel under the band width of 40M- or 40M+ is set as n. Therefore, the 40M automatic channel can be selected in the 1-13 full range.
Description
technical field [0001] The present invention relates to the field of wireless communication, in particular to a method for selecting a channel with the best channel quality among all channels. Background technique [0002] Automatic channel selection, automatically search all channel quality, select the best channel for users to use. During wireless communication, a frequency band can be divided into many channels. At present, there are 13 transmission channels of wireless routers, and each channel has two frequency band widths, one is 20M and the other is 40M. Here, the frequency band of the router Width refers to the width of the router's transmission frequency. According to the frequency band width, the router's transmission scheme can be divided into two types of 20M bandwidth and 40M bandwidth. There are two automatic channel selections during the user's use, which are called 40M automatic channel selection and 20M automatic channel selection. Channel selection, among ...
