Background technique

With the popularity of wireless networks, wireless routers are also moving toward higher end.

A wireless router is a radio frequency (RF) system that needs to operate within a certain frequency range to be able to communicate with other devices. This frequency range is called the working frequency band of the wireless router. However, different router products use different network standards, and their working frequency bands are also different. The frequency bands in which wireless routers work are generally divided into two working frequency bands of 2.4 GHz and 5.0 GHz. 2.4GHz is a commonly used frequency band for early wireless routers, and has continued to the present; in recent years, 5.0GHz has also begun to be widely used, and combined with 2.4GHz to form a dual-band wireless router.

A dual-band wireless router is a wireless router that operates in both the 2.4 GHz and 5.0 GHz bands. Compared to a single-band wireless router, it has a higher wireless transmission rate, is more resistant to interference, and has a stronger and more stable wireless signal. Higher sex, not easy to drop, dual-band wireless router has become the mainstream development trend of wireless products.

In the prior art, the user usually needs to manually set the working frequency band of the dual-band wireless router. When the user needs to switch the current working frequency band to another frequency band, the manual setting is often required, which consumes more time and automation. not tall.

The specific meaning of the above terms in the present invention can be understood in a specific case by those skilled in the art.

Further, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not constitute a conflict with each other.

Referring to FIG. 1 , a flow chart of a first embodiment of a method for switching a frequency band based on a wireless device according to an embodiment of the present invention is shown. The frequency band may include at least a first working frequency band and a second working frequency band different from each other, where The data transmission rate of the first working frequency band is greater than the second working frequency band;

The embodiment of the present invention may specifically include the following steps:

Step 101: When the wireless device receives the access request of the access terminal, detecting the current signal strength of the access terminal.

Step 102: Connect the access terminal to a first working frequency band or a second working frequency band based on the current signal strength.

Step 103: Detect a signal strength of the access terminal in real time;

Step 104: Perform mutual switching between the first working frequency band and the second working frequency band based on the real-time signal strength.

In the embodiment of the present invention, when the wireless device receives the access request of the access terminal, the access terminal accesses the access terminal to the first working frequency band or the second working frequency band according to the obtained current signal strength of the access terminal. The real-time signal strength of the access terminal is detected, and the first working frequency band and the second working frequency band are switched according to the real-time signal strength. Thereby, automatic access and automatic switching of the working frequency band of the wireless device can be realized, and the degree of automation is high. At the same time, the working frequency band is switched in time with the change of the signal strength, which can reduce the signal interference caused by other wireless devices and improve the user's Internet access speed.

Referring to FIG. 2, a flow chart of a second embodiment of a method for switching a frequency band based on a wireless device according to an embodiment of the present invention is shown. The wireless device in the embodiment of the present invention may include a wireless router, a wireless network card, a wireless AP (Access Point, access point), and the like.

The wireless device supports at least two mutually different working frequency bands, that is, a first working frequency band and a second working frequency band, wherein the working frequency band refers to a frequency range in which the wireless device can communicate with other devices. For example, when the wireless device is a dual-band wireless router, the first working frequency band may be the 5.0 GHz frequency band, and the second working frequency band may be the 2.4 GHz frequency band. Among them, the frequency range of the 2.4 GHz band is 2401 MHz - 2487 MHz, and the frequency range of the 5.0 GHz band is 4980 MHz - 5825 MHz.

In the embodiment of the present invention, the data transmission rate of the first working frequency band is greater than the second working frequency band. For example, if the first working frequency band is the 5.0 GHz frequency band and the second working frequency band is the 2.4 GHz frequency band, the transmission distance of the 2.4 GHz frequency band can be 70 meters indoors and 250 meters outdoors, but the maximum speed of most 2.4 GHz is only 300 Mbps. The 5.0GHz rate is high, and it can reach 867Mbps in a short distance. The actual effective data transmission (throughput) is 3-5 times that of 2.4GHz, but its transmission distance is short, and the indoor transmission distance is only 35 meters.

The wireless network protocols followed by different working bands are shown in Table 1 below:

Table 1

Wireless protocol	Technical algebra	working frequency	Maximum transmission rate
IEEE 802.11a	First generation	5GHz	54Mbps
IEEE 802.11b	Second generation	2.4GHz	11Mbps
IEEE 802.11g	Third Generation	2.4GHz	54Mbps
IEEE 802.11n	Fourth Generation	2.4GHz and 5GHz	600Mbps (MIMO technology)
IEEE 802.11ac	Fifth Generation	5GHz	More than 500Mbps

The embodiment of the invention can better combine the advantages of the above two working frequency bands, automatically switch the working frequency band of the wireless device, and has a high degree of intelligence.

In addition, in the embodiment of the present invention, the network name (wifi name) and the login password of the first working frequency band and the second working frequency band may be set in the wireless device, and the network name of the two may be set and the login password may be set during the setting. The same, so users do not need to set different wireless network names for different working frequency bands, which is convenient for users to manage the network name and login password.

The embodiment of the present invention may specifically include the following steps:

Step 201: When the wireless device receives the access request of the access terminal, determine whether the access terminal supports the first working frequency band.

When the access terminal needs to connect to the network, the access terminal may send an access request to the wireless device, where the access request may include the terminal identifier, model, and the like of the access terminal.

After receiving the access request sent by the access terminal, the wireless device may query the wireless network protocol that the access terminal can support through the application interface API, if the wireless network protocol supported by the access terminal and the wireless corresponding to the first working frequency band If the network protocol matches, the wireless device can determine that the access terminal supports the first working frequency band.

Step 202: If the access terminal supports the first working frequency band, detecting a current signal strength of the access terminal;

After determining that the access terminal supports the first working frequency band, the wireless device can further invoke a standard wireless interface to query the current signal strength of the access terminal.

In a specific implementation, the unit of signal strength can be expressed as dB or dBm, and dB and dBm are units of power gain, and the differences are as follows:

dB is a value that represents the relative value. The pure ratio only represents the relative magnitude relationship between the two quantities. There is no unit. When considering the power of A is much larger or smaller than the power of B, the calculation formula is : 10log (A power / B power); if the voltage ratio of the two is used, the calculation used The formula is: 20log (A voltage / B voltage). For example, the power of A is twice as large as the power of B, then 10 lg (A power / B power) = 10 lg 2 = 3 dB. In other words, the power of A is 3dB greater than the power of B. On the other hand, if the power of A is half of the power of B, the power of A is 3 dB less than the power of B.

dBm is a value indicating the absolute value of power (it can also be considered as a ratio based on 1mW power), and the calculation formula is: 10log (power value / 1mw). For example, for a power of 40 W, the value calculated in dBm units should be: 10 log (40 W / 1 mw) = 10 log (40000) = 10 log 4 + 10 log 10000 = 46 dBm.

It should be noted that the value of the signal strength is represented by a negative number, and therefore, the signal strength of -40 dBm is larger than the signal strength of -50 dBm.

Step 203: If the current signal strength is greater than a first preset threshold, accessing the access terminal to the first working frequency band;

After obtaining the current signal strength of the access terminal, further determining whether the current signal strength is greater than a first preset threshold or less than a second preset threshold, and if the current signal strength is greater than a first preset threshold, The incoming terminal accesses the first working frequency band even if the access terminal operates in the first working frequency band.

It should be noted that the first preset threshold and the second preset threshold are all empirical values, and the specific setting of the first preset threshold and the second preset threshold is not limited in the embodiment of the present invention, and those skilled in the art according to The actual situation can be set.

For example, for a dual-band wireless router, if it detects that the current signal strength of the access terminal (such as a mobile phone) is greater than -40 dBm, the access terminal can be connected to the 5.0 GHz frequency band.

Step 204: Add an identifier of the access terminal to a pre-established device list.

After the access terminal accesses the first working frequency band, the wireless device may further add the identifier of the access terminal to the device list pre-established in the background. The pre-established device list is used to record terminal information of the access terminal connected to the wireless device to perform maintenance on the access terminal.

Step 205: Detect a real-time signal strength of the access terminal according to a preset time interval.

In the embodiment of the present invention, the monitoring process can be set, and the monitoring process periodically detects the real-time signal strength of the access terminal according to a preset time interval.

Step 206: In the process of the access terminal accessing the first working frequency band, if the real-time signal strength is less than a second preset threshold, the frequency band of the access terminal is used by the first The working frequency band is switched to the second working frequency band;

In practical applications, if the access terminal gradually moves away from the wireless device (ie, when the distance between the two increases), the monitoring process of the wireless device detects that the signal strength of the access terminal is weaker, that is, the value of the signal strength is greater. The smaller the signal strength is, the signal may be notified to the wireless device to switch the frequency band of the access terminal from the first working frequency band to the second working frequency band when the signal strength is less than the second preset threshold.

It should be noted that the value of the second preset threshold may be a value smaller than the first preset threshold, for example, the first preset threshold is -40 dBm, and the second preset threshold is -50 dBm. If the access terminal gradually moves away from the wireless router, when the real-time signal strength detected at a certain time is less than -50 dBm, the access terminal can be automatically switched from the 5.0 GHz band to 2.4 GHz.

Since the transmission distance of 5 GHz is only 35 meters, the wall penetration capability is poor, and it is only suitable for indoor small-range coverage and outdoor bridge. When the access terminal is gradually away from the wireless device, the signal attenuation is large, and the coverage distance of 2.4 GHz under the same power. Relatively far, therefore, when the signal is attenuated to less than -50dBm, the access terminal is automatically switched from the 5.0GHz band to 2.4GHz, which can ensure network stability.

Step 207: In the process of the access terminal accessing the second working frequency band, if the real-time signal strength of the access terminal is greater than the first preset threshold, the frequency band of the access terminal is used. Switching from the second working frequency band to the first working frequency band.

When the access terminal works in the second working frequency band, the monitoring process continues to periodically detect the real-time signal strength of the access terminal according to a preset time interval.

If the access terminal is gradually approaching the wireless device (that is, when the distance between the two is shortened), the monitoring process of the wireless device detects that the signal strength of the access terminal is getting stronger and stronger, that is, the value of the signal strength is getting larger and larger. When the signal strength is greater than the first preset threshold, the monitoring process may notify the wireless device to switch the frequency band of the access terminal from the second working frequency band to the first working frequency band.

For example, if the access terminal gradually approaches the wireless router, when the real-time signal strength detected at a certain time is greater than -40 dBm, the access terminal can be automatically switched from the 2.4 GHz band to the 5 GHz band.

In practical applications, with the popularity of IT equipment, devices such as ipads, mobile phones, PCs, game consoles, etc. are all used in the 2.4 GHz band. If multiple devices use the 2.4 GHz band at the same time, it will lead to overcrowding and throughput. The amount of value is seriously degraded. Moreover, microwave ovens, Bluetooth, wireless mice, etc. also use the 2.4GHz band, they will interfere with the wifi signal, so that the Internet speed is slow, resulting in network congestion. Therefore, when detecting that the signal strength of the current access terminal is greater than the first preset threshold, the embodiment of the present invention automatically switches the access terminal from the 2.4 GHz band to the 5 GHz band, thereby avoiding other uses. The device in the 2.4 GHz band interferes with the access terminal, improves the data transmission efficiency of the access terminal, and improves the user's online experience.

It should be noted that, in the embodiment of the present invention, a threshold value of N values is separated between the first preset threshold and the second preset threshold, and the threshold distance between the two is a certain critical distance. The advantage of setting only a preset threshold is to prevent the access terminal from frequently switching back and forth between the threshold thresholds (for example, when only one threshold is set to -50 dBm, the operating frequency bands of -51 dBm and -49 dBm are not the same. If the signal strength is between the two, the working frequency band needs to switch back and forth to improve the performance of the device. For example, the first preset threshold is -40 dBm, and the second preset threshold is -50 dBm. When the access terminal gradually moves away from the wireless device, the value between the two thresholds (eg, -45 dBm) operates in the 5 GHz band. When the access terminal is gradually approaching the wireless device, the value between the two thresholds (such as -45dBm) operates in the 2.4GHz band, giving the two bands a sufficient buffer to ensure network stability.

In the embodiment of the present invention, when the access terminal requests to access the wireless device, if the current signal strength of the access terminal is greater than the first preset threshold, the access terminal is connected to the first working frequency band to prevent other The device in the second working frequency band causes interference to the access terminal and improves the user's Internet access speed.

Then, the real-time signal strength of the access terminal is continuously detected. When the real-time signal strength is less than the second preset threshold, the access terminal is automatically switched from the first working frequency band to the second working frequency band, and the real-time is detected again. When the signal strength is greater than the first preset threshold, the access terminal is automatically switched from the second working frequency band to the first working frequency band, and two different thresholds are set, and the access terminal is automatically completed based on the signal strength of the access terminal. The switching of the working frequency band does not require the user to manually switch the working frequency band, and the degree of automation is high.

Referring to FIG. 3, a flowchart of a step of a method for performing a frequency band switching method based on a wireless device according to an embodiment of the present invention is shown. The wireless device in the embodiment of the present invention supports at least two working frequency bands that are different from each other, that is, the first The working frequency band and the second working frequency band, wherein the data transmission rate of the first working frequency band is greater than the second working frequency band.

In the embodiment of the present invention, the network name (wifi name) and the login password of the first working frequency band and the second working frequency band may be set in the wireless device, and the network name of the two is the same and the login password is the same when the setting is performed. In this way, the user does not need to set different wireless network names for different working frequency bands, which is convenient for the user to manage the network name and login password.

The embodiment of the present invention may specifically include the following steps:

Step 301: When the wireless device receives the access request of the access terminal, determine whether the access terminal supports the first working frequency band.

When the access terminal needs to connect to the network, the access terminal may send an access request to the wireless device, where the access request may include the terminal identifier, model, and the like of the access terminal.

After receiving the access request sent by the access terminal, the wireless device may query the wireless network protocol that the access terminal can support through the application interface API, if the wireless network protocol supported by the access terminal and the wireless corresponding to the first working frequency band If the network protocol matches, the wireless device can determine that the access terminal supports the first working frequency band.

Step 302: If the access terminal supports the first working frequency band, detecting a current signal strength of the access terminal.

After determining that the access terminal supports the first working frequency band, the wireless device can further invoke a standard wireless interface to query the current signal strength of the access terminal, wherein the value of the signal strength is represented by a negative number, and therefore, the signal strength ratio of -40 dBm - The signal strength of 50dBm is large.

Step 303: If the current signal strength is less than a second preset threshold, accessing the access terminal to the second working frequency band;

After obtaining the current signal strength of the access terminal, further determining whether the current signal strength is greater than a first preset threshold or less than a second preset threshold, and if the current signal strength is less than a second preset threshold, The incoming terminal accesses the second working frequency band even if the access terminal operates in the second working frequency band.

It should be noted that the first preset threshold and the second preset threshold are all empirical values, and the specific setting of the first preset threshold and the second preset threshold is not limited in the embodiment of the present invention, and those skilled in the art according to The actual situation can be set.

For example, for a dual-band wireless router, if it detects that the current signal strength of the access terminal (such as a mobile phone) is less than -50 dBm, the access terminal can be connected to the 2.4 GHz frequency band.

Step 304: Add an identifier of the access terminal to a pre-established device list.

After the access terminal accesses the second working frequency band, the wireless device may further add the identifier of the access terminal to the device list pre-established in the background. The pre-established device list is used to record terminal information of the access terminal connected to the wireless device to perform maintenance on the access terminal.

Step 305: Detect a real-time signal strength of the access terminal according to a preset time interval.

In the embodiment of the present invention, a monitoring process can be set, and the monitoring process can be used to periodically detect the real-time signal strength of the access terminal according to a preset time interval.

Step 306, in the process that the access terminal accesses the second working frequency band, if the real-time signal strength is greater than a first preset threshold, the frequency band of the access terminal is used by the second The working frequency band is switched to the first working frequency band;

In practical applications, if the access terminal gradually approaches the wireless device (ie, when the distance between the two is reduced), the monitoring process of the wireless device detects that the signal strength of the access terminal is getting stronger and stronger, that is, the value of the signal strength is increasing. The larger the signal strength is greater than the first preset threshold, the monitoring process may notify the wireless device to switch the frequency band of the access terminal from the second working frequency band to the first working frequency band.

It should be noted that the value of the first preset threshold may be a value greater than a second preset threshold. For example, the second preset threshold is -50 dBm, and the first preset threshold is -40 dBm. If the access terminal gradually approaches the wireless router, when the real-time signal strength detected at a certain time is greater than -40 dBm, the access terminal can be automatically switched from the 2.4 GHz band to 5.0 GHz.

In practical applications, with the popularity of IT equipment, devices such as ipads, mobile phones, PCs, game consoles, etc. are all used in the 2.4 GHz band. If multiple devices use the 2.4 GHz band at the same time, it will lead to overcrowding and throughput. The amount of value is seriously degraded. Moreover, microwave ovens, Bluetooth, wireless mice, etc. also use the 2.4GHz band, they will interfere with the wifi signal, so that the Internet speed is slow, resulting in network congestion. Therefore, when detecting that the signal strength of the current access terminal is greater than the first preset threshold, the embodiment of the present invention automatically switches the access terminal from the 2.4 GHz band to the 5 GHz band, thereby avoiding other devices using the 2.4 GHz band. It causes interference to the access terminal, improves the data transmission efficiency of the access terminal, and improves the user's online experience.

Step 307, in the process of the access terminal accessing the first working frequency band, if the real-time signal strength of the access terminal is less than a second preset threshold, the frequency band of the access terminal is used. Switching from the first working frequency band to the second working frequency band.

When the access terminal works in the first working frequency band, the monitoring process continues to periodically detect the real-time signal strength of the access terminal according to a preset time interval.

If the access terminal gradually moves away from the wireless device (ie, when the distance between the two increases), the monitoring process of the wireless device detects that the signal strength of the access terminal is weaker, that is, the value of the signal strength is getting smaller and smaller. When the signal strength is less than the second preset threshold, the monitoring process may notify the wireless device to switch the frequency band of the access terminal from the first working frequency band to the second working frequency band.

For example, if the access terminal gradually moves away from the wireless router, when the real-time signal strength detected at a certain time is less than -50 dBm, the access terminal can be automatically switched from the 5.0 GHz band to the 2.4 GHz band.

Since the transmission distance of 5 GHz is only 35 meters, the wall penetration capability is poor, and it is only suitable for indoor small-range coverage and outdoor bridge. When the access terminal is gradually away from the wireless device, the signal attenuation is large, and the coverage distance of 2.4 GHz under the same power. Relatively far, therefore, when the signal is attenuated to less than -50dBm, the access terminal is automatically switched from the 5.0GHz band to 2.4GHz, which can ensure network stability.

It should be noted that, in the embodiment of the present invention, a threshold value of N values is separated between the first preset threshold and the second preset threshold, and the threshold distance between the two is a certain critical distance. The advantage of setting only a preset threshold is to prevent the access terminal from frequently switching back and forth between the threshold thresholds (for example, when only one threshold is set to -50 dBm, the operating frequency bands of -51 dBm and -49 dBm are not the same. If the signal strength is between the two, the working frequency band needs to switch back and forth to improve the performance of the device. For example, the first preset threshold is -40 dBm, and the second preset threshold is -50 dBm. When the access terminal gradually moves away from the wireless device, the value between the two thresholds (eg, -45 dBm) operates in the 5 GHz band. When the access terminal is gradually approaching the wireless device, the value between the two thresholds (such as -45dBm) operates in the 2.4GHz band, giving the two bands a sufficient buffer to ensure network stability.
