Description

Wireless router and channel selection method and system thereof

Technical field

The present invention relates to the field of wireless router technologies, and in particular, to a wireless router and a channel selection method and system thereof.

Background technique

The wireless channel is a data signal transmission channel that uses a radio wave signal as a transmission medium. The quality of the wireless channel directly affects the quality and efficiency of wireless transmission. Therefore, it is especially important to select the wireless channel with better quality to improve the performance of the wireless router.

Usually the choice of wireless channel includes both automatic selection and manual selection. When the wireless device automatically connects to the wireless channel, the wireless router chooses to use the default channel. This will increase the probability of using the same channel, making wireless signals extremely conflicting and interfering, reducing the quality of wireless transmission. In the case of many wireless signals and large interference from the surrounding environment, the wireless performance will be directly affected, and even the cable may be dropped, resulting in the user not being able to use normally.

When the wireless device manually connects to the wireless channel, it is necessary to select a channel different from the surrounding wireless source to avoid the wireless co-channel interference and improve the wireless transmission effect. In addition, the wireless signal of one channel interferes with two channels adjacent to it at the same time. Therefore, when setting the wireless channel, two or more channels away from other wireless signal sources should be selected. But the average user still has no way of knowing which channel the router should work on because it has no effective means to obtain the quality of the wireless channel.

The number, the signal strength of each wireless access node; step S2, calculating the channel interference value of each channel according to the wireless device information; and step S3, selecting the channel with the smallest channel interference value as the wireless channel.

Although the above method achieves automatic selection of a preferred wireless channel to a certain extent, it only uses the number of wireless access nodes as a reference basis, and does not fully reflect the quality of each wireless channel, because the data of each wireless access node Transmission frequency, speed and other factors are different, so the party The law still has flaws.

Detailed ways

The invention will be further described in detail below with reference to the drawings and specific embodiments.

Example 1

A wireless router channel selection method includes the following steps:

The method obtains the usage of each wireless channel by scanning a beacon frame in the wireless channel, because the beacon frame generally includes information about the wireless device, such as the received signal strength, current work. Make channel, send data rate, etc. The quality of each wireless channel is then determined based on this series of information in order to make the best choice.

In addition, the selected wireless channel may be selected by the wireless router according to the corresponding setting, or may be selected by the user.

When the wireless router automatically selects the best wireless channel, it can set the corresponding judgment priority for each group of data, such as first determining the number of wireless devices working on each wireless channel, and selecting the least number of wireless channels; If the number of devices is the same, the average received signal strength of all wireless devices working on each wireless channel is determined, and the wireless channel with the highest received signal strength is selected; if there is still a wireless channel with the same average received signal strength, Then continue to determine the average transmission data rate of all wireless devices operating on each wireless channel, and select the wireless channel with the fastest average transmission data rate; if there is a wireless channel with the same average transmission data rate, then continue to judge other data or A wireless channel that meets the requirements is then selected.

The above is a method for automatically selecting an optimal wireless channel by a wireless router, and can also perform unified judgment on all data, for example, according to the influence of each data on the quality of the wireless channel, assign a corresponding weight to each data, and then The ownership values of each wireless channel are added, and finally the wireless channel selection is performed according to the size of the total weight. Specifically, if the number of wireless devices has a large impact on the quality of the wireless channel, the weight proportion of the number of devices may be increased correspondingly; and the weight ratio of the average signal strength and the average transmitted data rate may be correspondingly reduced.

When the user selects the wireless channel by himself, the data obtained by the scan analysis can be displayed through the terminal, so that the user can make a selection. Specifically, since the working channel of the general wireless router is set through the webpage management interface, the corresponding function module may be added to the webpage management interface to display the relevant data of the wireless channel quality by means of a graph or the like to intuitively The wireless channel quality information is presented to the user, and the user makes a selection based on the information.

In addition, it is more convenient to automatically select a wireless channel through a wireless router. Once the quality of the wireless channel in the surrounding environment changes, the wireless router can switch to the optimal wireless channel. The user's own choice of the wireless channel can better reflect the subjective will of the user, and is also more flexible. For example, the user can predict the change trend of the wireless environment after the relevant information to make a reasonable choice.

Example 2

The step of obtaining communication quality in step 2 described in Embodiment 1 is specifically:

By analyzing the scanned beacon frame to obtain related information of the wireless device working on the current wireless channel, and then processing to obtain the number of wireless devices, average signal strength, average transmission data rate, etc., which can be used to determine the quality of the wireless channel. . The three sets of data are the most critical data affecting the quality of the wireless channel, and the wireless channel selection made according to the data is relatively reliable.

The method for selecting the optimal wireless channel in the step 2 is specifically: setting a corresponding weight for the number of the wireless devices, the average signal strength, and the average transmission data rate, and selecting according to the total weight of each wireless channel.

The above method is a specific method for selecting a wireless channel, and the efficiency in the work is higher, and the selection made is more reasonable and reliable.

Since the impact of each group of data on the quality of the wireless channel is different in practice, a higher weight weight proportion can be allocated to the data having a larger influence, and a corresponding lower weight is allocated to the data having a smaller influence. The value is then weighted and then the sum of the weights obtained for each of the final wireless channels is used to rank the quality of the wireless channel in order to select the highest quality wireless channel.

The proportion of the weight of the wireless device is greater than the average signal strength and the average transmission data rate.

Specifically, the number of wireless devices operating on the wireless channel is a factor that affects the quality of the wireless channel, so the weight of the weight is greater than the other two data. For example, the number of wireless devices accounts for 50% or more of the weight, while other data share a total of 50% or less.

The specific weight of the number of wireless devices is inversely proportional to its value.

Obviously, the more wireless devices are working on the wireless channel, the better the quality of the wireless channel will be, and the congestion will be more likely to occur. Therefore, the greater the number of wireless devices, the smaller the weight of the corresponding wireless channel, and vice versa.

The specific weights of the average signal strength and the average transmitted data rate are all proportional to their values.

The average signal strength and the average transmission data rate reflect the stability and quality of the wireless channel to a certain extent, and the stronger the average signal strength or the faster the average transmission data rate, the higher the quality of the wireless channel, and the corresponding The greater the weight, the smaller the opposite.

In summary, in actual application, the weight of 0-100 can be allocated in an inverse relationship according to the number range of wireless devices. For example, if the number of wireless devices is 0, the corresponding weight is 100; if the wireless device The quantity is the set maximum value, such as 100, and the corresponding weight is 0. The average signal strength is assigned a weight of 0-60 in a proportional relationship according to the range of change that can be accessed. For example, if the average signal strength is the set minimum value, the corresponding weight is 0; if the average signal strength is For the set maximum value, the corresponding weight is 60. Then, the average data rate is transmitted, and the weights of 0-40 are allocated in a proportional relationship according to the range of the change. For example, if the average transmission data rate is the minimum value in the range, the corresponding weight is 0; if the average transmission data rate is The maximum value in the range, the corresponding weight is 40. Finally, the weights of the three sets of data are added to obtain a total weight representing each wireless channel, and the wireless channel with the largest total weight is automatically selected, or the data information and the analysis result are passed through the management interface of the wireless router. The way to show, so that users make the best choice.

The invention also provides a wireless router, comprising:

The wireless router first scans the beacon frame of the wireless channel supported by the surrounding environment by its scanning module, and then passes through the processing module to acquire related data of each wireless channel according to the scanned beacon frame, such as a wireless device. The number, the average signal strength, the average transmission data rate, etc., finally selects the best wireless channel according to the result of the processing module by the selection module.

It should be noted that the selection module may be a module that the wireless router automatically selects a wireless channel, or may be a module that provides the user with relevant wireless channel data and a selection button.

When the wireless router automatically selects the best wireless channel, according to the above method, all the data are assigned corresponding weights according to the impact on the quality of the wireless channel, and then the ownership values of each wireless channel are added, and finally according to the total The size of the weight is used for wireless channel selection. Specifically, wireless settings If the quantity of the backup has a great influence on the quality of the wireless channel, the weight proportion of the number of devices can be increased correspondingly; and the weight ratio of the average signal strength and the average transmission data rate can be correspondingly reduced.

The wireless router further includes:

a storage module, configured to store a result of the processing module;

The foregoing storage module is configured to store the result of the processing module in time, so as to facilitate the uploading of the module at any time, and ensure the integrity of the historical data, so that the user can understand the overall wireless channel condition to make a better choice.

The uploading module can display the obtained data through a channel such as a management interface of the wireless router in a chart or the like. Here, the webpage management end of the wireless router is taken as an example, because the setting or selection of the wireless channel is generally through the webpage management interface. . However, it is not excluded to complete through other terminals, such as mobile phones.

The webpage management terminal includes:

The above system is a preferred method for wireless channel selection, and performs related control operations and data feedback through interaction between the wireless router and its webpage management terminal, so that the user can intuitively understand each wireless channel through the webpage management interface of the wireless router. The quality of communication in order to make the best choice.

Specifically, a separate page may be added to the webpage management interface of the wireless router, and a button is set on the page, and the button is pressed to start the control module to control the communication quality of the wireless router for the wireless channel. The data is acquired, and then the acquired data is displayed in the form of a graph through the display module. In the displayed graph, the wireless channel can be the abscissa and the quality of the wireless channel is the ordinate. The specific ordinate can be the total weight in the above method. Users can clearly see the quality of all wireless channels in order to make a choice.

In addition, each wireless channel that can set the abscissa can be clicked, and the detailed statistics of the wireless channel are displayed after clicking, including the number of wireless devices, the average signal strength, the average transmission data rate, and the like.
