Abstract
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
The present invention relates to wireless communication field, particularly a kind of in all channels the method for selective channel channel the best in quality.
Background technology
Automatic channel is selected, and all channel qualities of automatic search select optimum channel for the user.During radio communication, can be divided into a lot of channels a frequency range, at present, the emission channel of wireless router has 13, the bin width of each channel has two kinds, a kind of is 20M, a kind of is 40M, here, the bin width of router refers to the width of router tranmitting frequency, according to bin width, the launch scenario of router can be divided into two kinds of 20M bandwidth and 40M bandwidth, in user's use procedure, there are two kinds of automatic channels to select, being called the selection of 40M automatic channel and 20M automatic channel selects, wherein the 40M automatic channel selects to be divided into again 40M+ and two kinds of forms of 40M-, the user is when using the 40M+ automatic channel to select, can only select 1～9 one in totally 9 channels, when if the user need to use the 40M-automatic channel to select, can only select 5～13 one in totally 9 channels.But, when choice for use 20M bandwidth, but can in totally 9 channels, select optimum channel to use 1～13.Therefore, for the user, if need to use the channel of 40M bandwidth, the user has two kinds of selections, it is to use the 40M+ automatic channel to select that the first is selected, the another kind of selection is to use the 40M-automatic channel to select, but when current optimum channel is the 11st channel, and user's selection is can not use optimum channel while using the 40M+ automatic channel to select, need the user to reselect and use the selection of 40M-automatic channel just can choose the channel channel that namely sequence number is 11 of current the best, vice-versa, such router has brought inconvenience to the user, because in advance and do not know it is what channel the best, after user's choice for use 40M+ automatic channel is selected or is used the 40M-automatic channel to select, can only in selected 9 channels, automatically select best channel to use, that is to say, the selection of user's choice for use 40M+ automatic channel or use 40M-automatic channel may not use best channel after selecting, can only use selected 1～9 totally 9 channels or 5～13 optimum channel in totally 9 channels, make user's benefit damage.
Summary of the invention
The objective of the invention is in order to allow the wireless router user when choice for use 40M automatic channel is selected, can select best channel simultaneously in 13 channels, and a kind of automatic channel system of selection provided.
Technical scheme of the present invention is: a kind of automatic channel system of selection, and the channel that the router automatic search is all, select optimum channel for the user, when the user being detected and select 40M automatic channel selection option, comprises the following steps:
Step 1, system enter 20M automatic channel selection mode;
Step 2, system are carried out the automatic channel selection under 20M automatic channel selection mode, obtain optimum channel, and preserve its sequence number;
Step 3, judge described optimum channel sequence number, if described optimum channel sequence number is less in 1～13, turn to step 4; Otherwise turn to step 5;
Step 4, system are carried out the automatic channel selection under 40M+ automatic channel selection mode, obtain optimum channel, and the working channel of router is fixed to this optimum channel;
Step 5, system are carried out the automatic channel selection under 40M-automatic channel selection mode, obtain optimum channel, and the working channel of router is fixed to this optimum channel.
Further, in above-mentioned automatic channel system of selection: in described step 3, described optimum channel sequence number is less than at 6 o'clock, turns to step 4; Otherwise turn to step 5.
Further, in above-mentioned automatic channel system of selection: in described step 3, described optimum channel sequence number is less than at 8 o'clock, turns to step 4; Otherwise turn to step 5.
In the present invention, the user of router, when selecting the channel of 40M bandwidth, can be selected in whole 13 channels.
Below in conjunction with specific embodiment, the present invention is described in more detail.
The accompanying drawing explanation
Fig. 1 is the overall flow figure that uses this method.
Embodiment
Embodiment 1, and the present embodiment is a kind of method that wireless router carries out the optimum channel selection, and as shown in Figure 1, the method, realize the optimum channel selection, and the working channel of wireless router is being fixed on best channel.
When the user being detected and select the 40M automatic channel to select option, comprise the following steps:
Step 1, system enter 20M automatic channel selection mode.Due at present, 20M automatic channel selection mode can be selected simultaneously in 13 channels, and the 20M bandwidth overlaps substantially with the centre frequency of 40M bandwidth, it is the bandwidth difference, so best frequency range of channel quality when the 20M bandwidth, when the 40M bandwidth, be also best frequency range, therefore, the sequence number of optimum channel when the sequence number of the optimum channel of selecting by 20M automatic channel selection mode is also the 40M bandwidth.
Step 2, system are carried out the automatic channel selection under 20M automatic channel selection mode, obtain optimum channel, and preserve its sequence number.
Step 3, judge described optimum channel sequence number, if described optimum channel sequence number is less in 1～13, turn to step 4; Otherwise turn to step 5; Preferential mode is, when the optimum channel sequence number is less than 6, to turn to step 4; Otherwise turn to step 5; Perhaps, when the optimum channel sequence number is less than 7, turn to step 4; Otherwise turn to step 5
Step 4, system are carried out the automatic channel selection under 40M+ automatic channel selection mode, obtain optimum channel, and the working channel of router is fixed to this optimum channel;
Step 5, system are carried out the automatic channel selection under 40M-automatic channel selection mode, obtain optimum channel, and the working channel of router is fixed to this optimum channel.
The present embodiment has proposed a kind of automatic channel of 40M bandwidth and has selected implementation method, and after the user selects 40M automatic channel selection option, equipment can be selected the preferred channels in 1 ~ 13 channel according to the channel signal to noise ratio.
After the thinking of design is selected option for the user issues the 40M automatic channel, at first system is set to the 20M bandwidth by bandwidth, and the 20M bandwidth does not have 20M+ or 20M-concept, and the scope that its automatic channel is selected is gamut 1 ~ 13.Get preferred channels n under the 20M bandwidth after, then channel is established and got back to 40M-or 40+ bandwidth, finally the channel under 40M-or 40+ bandwidth is set to n.Thereby realize that the 40M automatic channel can be in 1 ~ 13 gamut selection.
