Prior technical documents patent documents Patent Document 1: Japanese Patent Application Publication No. 2003-333640 Patent Document 2: Japanese Patent Application Publication No. 2015-192315 Patent Document 3: Japanese Patent Application Publication No. 2004-336351 Patent Document 4: International Publication No. 2012/137908

In recent years, in wireless LAN, the 2.4GHz band and the 5GHz band can be used. Furthermore, in the 5GHz band, W52 of the 5.2GHz band, W53 of the 5.3GHz band, and W56 of the 5.6GHz band can be used. At the same time, 2.4G, W52, W53, W56 is a communication capable device in all frequencies.

However, the frequency of the 5.2 GHz band overlaps with the feeder link frequency of the satellite communication system. In addition, the 5.3 GHz band and the 5.6 GHz band do not overlap or are adjacent to the weather radar frequency. Therefore, in home wireless LAN, the use of each band is imposed. restrictions on.

Recently, global efforts have begun to use frequencies in the 6GHz band for wireless LANs. In the United States, U-NII5 (5.925-6.425GHz) and U-NII7 (6.525-6.875GHz) have been allowed to be used as Standard Power AP (standard power access point, which can communicate outdoors) and Low Power AP (low power access point). entry point, indoor communication only). In addition, in U-NII6 (6.425-6.525GHz) and U-NII8 (6.875-7.125GHz), only Low Power AP is allowed to be used. In addition, Very Low Power (very low power) with smaller output power is also being studied.

Japan also issued and implemented a new provincial order on the introduction of 6GHz band wireless LAN on September 2, 2022. As a low-power data communication system, it stipulates a new frequency band (5925MHz~6425MHz) in the 6GHz band. The new provincial order stipulates that wireless stations that can be used indoors with limited use are subject to LPI (Low Power Indoor: Low Power Indoor) with an equivalent isotropic radiated power (EIRP) of up to 200mW. Wireless stations that can be used indoors and outdoors The radio targets VLP (Very Low Power) with a maximum EIRP of 25mW.

Table 1 below shows the current constraints for each band in September 2022. 【Table 1】 Available places Dynamic Frequency Selection (DFS) 2.4GHz Indoor and outdoor unnecessary 5GHz W52 Indoor only unnecessary 5GHz W53 Indoor only need 5GHz W56 Indoor and outdoor need 6GHz VLP Indoor and outdoor unnecessary 6GHzLPI Indoor only unnecessary

As recorded in Table 1, the 2.4GHz frequency band and W56 frequency band can be used indoors and outdoors, while the W52 frequency band and W53 frequency band can only be used indoors.

In addition, DFS (Dynamic Frequency Selection: Dynamic Frequency Selection) stipulates the detection of radar waves in wireless LAN equipment and the transmission stop at the time of detection (as well as to other channels) in order to avoid adverse effects on C-band radar, which is mainly used for weather observation. (movement) obligations. In the W53 frequency band and W56 frequency band, it is mandatory to carry the DFS function.

For the 6GHz band, VLP can be used indoors as well as outdoors, but LPI can only be used indoors.

Recently, as a method of utilizing wireless LAN, as shown in Figure 16, a router is installed in the main room, a repeater is placed in the side room, and communication is performed through the wireless LAN between the wireless LAN router and the wireless LAN repeater. , the use of wireless LAN for communication between a wireless LAN repeater and the host computer located in the room has begun again.

At this time, since the wireless LAN router and the wireless LAN repeater are equivalent to an outdoor communication path, communication must be performed using the 2.4GHz band, 5GHzW56 band, or 6GHz band VLP. However, conventional wireless LAN routers and wireless LAN repeaters are technically capable of communicating even in the 5GHz W52 band, W53 band, and 6GHz band LPI. If the devices are connected via the 5GHz W52 band, W53 band, or 6GHz band LPI via an outdoor communication path, it is considered to violate laws and regulations and have a negative impact on radars, etc.

In addition, at startup, when outdoor use is permitted by law and the W56, which has a large communication capacity, communicates between the router and the repeater, when radar waves are detected by the wireless LAN router, the wireless LAN router controls the Algorithm, it is also possible to switch the wireless band to W52 or W53 which is prohibited for outdoor use.

In addition, even if a wireless LAN repeater has a function to switch communication with the host from W56 to the 2.4GHz band when radar waves are detected, the information on the detection of radar waves cannot be transmitted to the wireless LAN router. , so even if radar waves cannot be detected by the wireless LAN router, there is a possibility that the communication between the wireless LAN router and the wireless LAN repeater will maintain the W56 band.

In the invention described in Patent Document 1, a display terminal that constitutes a wireless communication system with an infrastructure device is equipped with a detector for determining whether the device is indoors or outdoors. However, the detector described in Patent Document 1 detects whether the device is indoors or outdoors. As shown in Figure 6, the wireless LAN repeater is indoors, between the wireless LAN router and the wireless LAN repeater. If it is outdoors, it is judged to be indoors.

In addition, in the wireless communication device (repeater for wireless LAN) of the invention described in Patent Document 2, only when the first communication unit connected to the router is using the W52 band or the W53 band, that is, it is determined that the router is When the communication path with the repeater is indoors, the W52 frequency band and W53 frequency band are allowed to be used for the second communication unit connected to the host. However, when the wireless LAN repeater and the host shown in Figure 6 are located indoors and the wireless LAN router and the wireless LAN repeater are outdoor communication paths, even if the wireless LAN router and the wireless LAN router The 2.4GHz or W56 band is used between repeaters, and the W52 band or W53 band can be used between the wireless LAN repeater and the host. Therefore, the control algorithm of the invention described in Patent Document 2 is not suitable for the usage described in FIG. 6 .

In addition, the invention described in Patent Document 3 is an invention of an information communication device equipped with a wireless LAN. Since there is no description about communication with a host that is a necessary function in a wireless LAN repeater, and there is no description about the detection of In the case of radar waves, the present invention cannot be a solution to the technical problem to be solved by the present invention.

In addition, in the invention described in Patent Document 4, the location information of the device is acquired, and when the location of the device is a location with a high possibility of being used outdoors, the first frequency band and the second frequency band are selected and used. A wireless communication method in a frequency band that is allowed to be used outdoors. However, in the case of the invention described in Patent Document 4, only this device detects location information. Therefore, the wireless LAN repeater and host shown in FIG. 6 are located indoors, and the wireless LAN router and wireless LAN router are located indoors. When the distance between repeaters is outdoors, there is a possibility that the wireless communication method that can be used may be misjudged.

In addition, Patent Document 4 does not describe the detection of radar waves.

The main object of the present invention is to provide a wireless LAN repeater, a wireless LAN router and a wireless LAN system equipped with a wireless LAN channel switching method, which are arranged in a wing room, etc. and are compatible with a wireless LAN router arranged in a main room, etc. A wireless LAN repeater connected via an outdoor communication path can use the radio wave frequency band that is stipulated by laws and regulations and can be used outdoors, and the frequency band with a larger communication capacity can be used with priority.

A further object of the present invention is to provide a wireless LAN repeater, a wireless LAN router and a wireless LAN system equipped with a wireless LAN channel switching method. In the router, when radar waves in the W56 band are detected and the wireless LAN router and wireless LAN repeater cannot be connected on the existing channel, the wireless LAN router and the wireless LAN repeater can be reconnected in a frequency band with a large communication capacity as much as possible, and the wireless LAN router can be reconnected with the communication capacity. When a large frequency band is connected to a wireless LAN router, the frequency band can be restored as quickly as possible.

(1) According to one aspect of the wireless LAN repeater, the wireless LAN repeater includes a room mode used when the wireless LAN router is connected to the wireless LAN router through the outdoor communication path and is connected to the first host through the indoor communication path, It has a wireless communication circuit that can communicate in the 2.4GHz frequency band, a wireless communication circuit that can communicate in the 5GHz frequency band, and a wireless communication circuit that can communicate in the 6GHz frequency band. When the room mode is activated, the 6GHz frequency band VLP (Very Low Power), 5GHzW56 While selecting the most suitable communication environment among the frequency bands and the connectable frequency bands in the 2.4GHz frequency band and connecting to the wireless LAN router, for the first host, based on the host's request, the 2.4GHz frequency band, 5GHz frequency band and/or 6GHz frequency band are used. connection.

In addition, when the connection between the wireless LAN repeater and the first host is in the 6GHz band, the connection can also be made in the 6GHz band LPI (Low Power Indoor).

In addition, in the above-mentioned 6GHz band, 5GHz band, or 2.4GHz band, when connecting to the wireless LAN router and the host computer in the same frequency band at the same time, the same channel is used for connection in each frequency band. In addition, connecting in the 2.4GHz frequency band, 5GHzW56 frequency band and/or 6GHz frequency band means connecting in a frequency band selected from the group consisting of the 2.4GHz frequency band, 5GHzW56 frequency band and 6GHz frequency band, including individual and all combinations.

When the wireless LAN router is placed in the main room and the wireless LAN repeater is placed in a separate room from the main room, the wireless LAN repeater is connected to the wireless LAN router via an outdoor communication path. It is against the law when using the 5GHz W52 band, W53 band or 6GHz band LPI. However, in the wireless LAN repeater according to one aspect, in communication between the wireless LAN router and the wireless LAN repeater, only the 6 GHz band VLP, the 5 GHz W56 band, or the 2.4 GHz band that allows communication outdoors is used. The frequency band has no possibility of affecting satellite communication systems, weather radars, Dentsu services (fixed satellites, etc.), and will not violate laws and regulations.

In addition, in the wireless LAN repeater according to one aspect, the most suitable communication environment among the 6GHz band VLP, 5GHz W56 band and 2.4GHz band is selected and connected. Therefore, for example, when the distance between a wireless LAN router and a wireless LAN repeater is long, compared with the 6GHz band VLP, which has a wide frequency band but a maximum EIRP of 25 mW and is smaller, the frequency band is narrower but the EIRP is smaller. When the maximum EIRP is 1000mW (with TPC) and the communication capacity of the larger 5GHzW56 frequency band is large, by selecting the 5GHzW56 frequency band, you can choose a communication environment with larger communication capacity.

It should be noted that when the wireless LAN repeater has two or more wireless communication circuits capable of communicating in the 5GHz band, the connection with the wireless LAN router can also be set to the W56 band in the 5GHz band, and the The connection to the first host is set to W52 or W53.

(2) The wireless LAN repeater according to one aspect of the second invention includes a wireless communication circuit capable of communicating in the 2.4 GHz band, a wireless communication circuit capable of communicating in the 5 GHz band, and a wireless communication circuit capable of communicating in the 6 GHz band. The wireless communication circuit may each be composed of one circuit.

In this case, the circuit scale of the wireless communication circuit can be reduced.

It should be noted that when using multi-link operation (MLO) that can simultaneously utilize multiple frequency bands when connecting in WiFi7 and other systems that are expected to be put into practical use in the future, in order to smoothly start MLO, it is preferable to use a wireless LAN relay The connection between the device and the host in the 5GHz band is limited to W56.

(3) In the wireless LAN repeater according to one aspect of the third invention, when the wireless LAN router cannot be connected to the wireless LAN router in the 6 GHz band VLP, the wireless LAN router is requested to be able to connect in the 6 GHz band VLP. , if the 6GHz band VLP can be connected, you can again select the most suitable communication environment from the connectable frequency bands of the 6GHz band VLP, 5GHzW56 band, and 2.4GHz band and connect to the wireless LAN router.

If the wireless LAN repeater of the present invention can use the 6 GHz frequency band as a connection with the indoor host, it will use the 6 GHz frequency band LPI connection with large communication capacity. However, when the wireless LAN repeater has a function of setting LPI/VLP for each connected terminal, the wireless LAN repeater can also be connected to the wireless LAN router using the 6 GHz band VLP.

In the wireless LAN repeater with this function, when the wireless LAN router does not allow VLP connection in the 6GHz band and connects in the 5GHzW56 band or the 2.4GHz band, the wireless LAN repeater will be connected to the wireless LAN router. Send a connection request for the 6GHz band VLP. If the connection can be made with the 6GHz band VLP, the most suitable communication environment is selected again from the connectable frequency bands of the 6GHz band VLP, the 5GHzW56 band, and the 2.4GHz band and connected to the wireless LAN router. , when the communication environment of 6GHz band VLP is most suitable, switching to 6GHz band VLP can increase the communication capacity of wireless LAN routers and wireless LAN repeaters.

It should be noted that even among wireless LAN repeaters that do not have the function of setting LPI/VLP for each connected terminal, for example, among the hosts of the wireless LAN repeater, there is no host capable of communicating in the 6 GHz band. etc., when it is not necessary to use the 6GHz band LPI for connection with the host, or when you want to make the communication capacity of the wireless LAN repeater and the wireless LAN router larger than that of the wireless LAN repeater and the host. When communication capacity is prioritized to increase, the wireless LAN repeater can also send a 6GHz band VLP connection request to the wireless LAN router.

However, it is not a standard function of the wireless LAN router to accept the connection request of the 6GHz band VLP, but a separate function. Therefore, in order for the wireless LAN router to accept the connection request of the 6GHz band VLP and allow the connection of the 6GHz band VLP, it is necessary to use a wireless LAN router equipped with room mode.

(4) The wireless LAN repeater according to the fourth invention is the wireless LAN repeater according to one aspect. When the wireless LAN router is connected to the wireless LAN router in the 5GHzW56 frequency band and cannot be connected to the 5GHzW56 frequency band, an attempt is made to connect to another wireless LAN router in the 5GHzW56 frequency band. If the connection on the channel cannot be connected to another channel in the 5GHzW56 band, you can select the most suitable communication environment from the connectable bands in the 6GHz band VLP and 2.4GHz band and connect to the wireless LAN router .

When a wireless LAN repeater is connected to a wireless LAN router through a channel of the 5GHz W56 band, the wireless LAN router monitors radar waves, and when a radar wave is detected, it stops on the connected channel of the 5GHz W56 band. The connection transmits communications capable of any one of the 6GHz band VLP, the other channel of the 5GHzW56 band, and/or the 2.4GHz band to the wireless LAN repeater.

At this time, the wireless LAN repeater first attempts connection on another channel of the 5GHz W56 frequency band, and if the connection can be made, continues the connection on the other channel.

On the other hand, if connection cannot be made on another channel of the 5GHz W56 band, the most suitable communication environment is selected from the connectable frequency bands of the 6GHz band VLP and the 2.4GHz band, and connected to the wireless LAN router.

The reason why the connection on the other channel of the 5GHzW56 band is prioritized is to avoid an increase in the processing load of the wireless LAN repeater when returning to startup every time a radar wave is detected, and to avoid the need to connect to the first host. Changes, etc. may affect the communication between the wireless LAN repeater and the first host.

(5) The wireless LAN repeater according to the fifth invention is the wireless LAN repeater according to one aspect. When the wireless LAN repeater is connected to the wireless LAN router in the 5GHzW56 frequency band and cannot be connected in the 5GHzW56 frequency band, While the 6GHz band VLP or 2.4GHz band is connected to the wireless LAN router, check the possibility of connection on another channel of the 5GHzW56 band. If connection is possible on another channel of the 5GHzW56 band, you can start the 6GHz band VLP again. Select the most suitable communication environment among the connectable frequency bands in the 5GHz, W56 and 2.4GHz bands, and connect to the wireless LAN router.

In the wireless LAN repeater of the fourth invention, first, a connection is attempted on another channel in the 5 GHz W56 band, and if the connection is possible, the connection is made on another channel, thereby reducing the throughput of the wireless LAN repeater. Increases the impact on communication between the wireless LAN repeater and the first host.

However, at this time, in order to connect to another channel, it is necessary to confirm that there is no radar wave for at least 1 minute. Therefore, the connection between the wireless LAN router and the wireless LAN repeater is stopped for at least 1 minute.

In the wireless LAN repeater of the fifth invention, in order to avoid the 1-minute communication stoppage, first, check whether it is connected to the wireless LAN router in the 6GHz band VLP or the 2.4GHz band, and in parallel, it is connected to another channel in the 5GHz W56 band. If the connection possibility is possible on another channel of the 5GHzW56 band, select the most suitable communication environment from the 6GHz band VLP, the 5GHzW56 band, and the 2.4GHz band that can be connected, and connect to the wireless LAN router.

It should be noted that when connection is possible on another channel of the 5GHz W56 band, the connection with the wireless LAN router can also be switched to another channel of the 5GHz W56 band.

(6) The wireless LAN repeater according to the sixth aspect of the invention confirms at predetermined time intervals whether it can connect to the wireless LAN router in the 6 GHz band VLP and the 5 GHz W56 band. When any one of the frequency bands is changed from unconnectable to connectable, the most suitable communication environment can be selected again from the connectable frequency bands of the 6GHz band VLP, 5GHzW56 band, and 2.4GHz band, and connected to the wireless LAN router.

At startup, even if the most suitable communication environment is selected and connected from the connectable frequency bands in the 6GHz band VLP, 5GHzW56 band, and 2.4GHz band, after the specified time has passed, the 6GHz band VLP and 5GHzW56 band Any one of will change from unconnectable to connectable.

For example, a mobile device such as a smartphone connected to a wireless LAN router using the 6 GHz band LPI may go out with the user, or the radio waves of the radar may be interrupted due to time periods.

Therefore, it is preferable to check whether the connection to the wireless LAN router can be made in the 6GHz band VLP and the 5GHzW56 band, and when either one of the 6GHz band VLP or the 5GHzW56 band is changed from unconnectable to connectable, it is preferable to return when activating the cabin mode. to select the most appropriate communication environment and reconnect.

It should be noted that the prescribed time at this time is, for example, 30 minutes.

(7) The wireless LAN repeater according to the seventh aspect of the invention may be provided with a plurality of SSIDs, and the SSID connected to the wireless LAN router corresponds to the 6 GHz band VLP, and the SSID of the first host The SSID corresponds to the 6GHz band LPI.

In this case, the wireless LAN router connected via the outdoor communication path belongs to the SSID corresponding to the 6GHz band VLP, and the first host connected via the indoor communication path belongs to the SSID corresponding to the 6GHz band LPI. This can reliably prevent legal violations. and maximizing the communication capacity to the first host.

(8) The wireless LAN router according to the eighth invention is a wireless LAN router equipped with a room mode used when connecting to a wireless LAN repeater via an outdoor communication path and at the same time connecting to a second host via an indoor communication path, and is equipped with a 2.4 GHz A wireless communication circuit that can communicate in the frequency band, a wireless communication circuit that can communicate in the 5GHz frequency band, a wireless communication circuit that can communicate in the 6GHz frequency band, a network circuit that can connect to wired WAN and LAN, and a wireless communication circuit that can communicate in the 6GHz frequency band. The wireless communication circuit is configured so that each connection terminal of the wireless LAN repeater and the second host can select and communicate from the 6 GHz band VLP and the 6 GHz band LPI.

However, when the wireless LAN router is a wireless LAN access point, the network circuit may not be required.

At this time, if the wireless LAN router is set to the private room mode, for example, it can be connected to the wireless LAN repeater connected via the outdoor communication path in the 6GHz band VLP, and can be connected to the second host connected via the indoor communication path in the 6GHz band. LPI connection does not violate laws and regulations, and can provide maximum communication capacity to wireless LAN repeaters and second hosts.

In addition, when the wireless LAN repeater also has the private room mode, the notification of the connection via the outdoor communication path can be received from the wireless LAN repeater, but the connection with the wireless LAN repeater is generally not known. Whether via outdoor communication path. At this time, when starting up the wireless LAN router, the MAC address of the terminal connected via the outdoor communication path may be input.

In addition, since it is possible to communicate with both the 6GHz band VLP and the 6GHz band LPI using one wireless communication circuit capable of communicating in the 6GHz band, the circuit scale of the wireless LAN router can be reduced.

It should be noted that a wireless LAN router has two or more wireless communication circuits that can communicate in the 5GHz band. In 5GHz communication, the connection with the wireless LAN repeater can be set to W56, and the connection with the second wireless LAN repeater can be set. The host's connection is set to W52 or W53.

(9) The wireless LAN router according to the ninth invention. In the wireless LAN router according to the eighth invention, you may have a plurality of SSIDs, and the SSID connected to the wireless LAN repeater corresponds to the 6GHz band VLP, and the SSID connected to the second host The SSID corresponds to the 6GHz band LPI.

In this case, the wireless LAN repeater connected via the outdoor communication path belongs to the SSID corresponding to the 6GHz band VLP, and the second host connected via the indoor communication path belongs to the SSID corresponding to the 6GHz band LPI, thus violating the law can be reliably achieved. avoidance and maximization of communication capacity to the second host.

(10) The Wireless LAN Router of the Tenth Invention In the wireless LAN router of the eighth invention, the second host and the wireless LAN repeater can be identified by receiving identification information from the wireless LAN repeater.

In a wireless LAN router, both the second host and the wireless LAN repeater can be connected as connection terminals. However, the wireless LAN router may not be able to identify which connection terminal is the second host and which connection terminal is the wireless router. Repeater for LAN.

According to the tenth aspect of the invention, the wireless LAN repeater transmits identification information indicating that it is a wireless LAN repeater corresponding to the private room mode, and the wireless LAN router can identify which connection terminal is the wireless LAN repeater by receiving the identification information. device.

Therefore, even if the user does not perform settings for identifying the wireless LAN repeater in advance (settings for inputting the MAC address, IP address, SSID, etc. of the wireless LAN repeater), it is possible to identify which connection terminal is capable of Whichever connection terminal is the second host for communication corresponding to the indoor communication path or the wireless LAN repeater that needs to perform communication corresponding to the outdoor communication path, an appropriate communication method can be automatically selected.

It should be noted that the wireless LAN repeater of any one of the inventions to the seventh invention can transmit the identification information, and the wireless LAN router of any one of the eighth invention to the eleventh invention can receive the identification. information to identify the second host and the wireless LAN repeater.

(11) The wireless LAN router of the eleventh invention is a wireless LAN router equipped with a room mode used when connecting to a wireless LAN repeater via an outdoor communication path and at the same time connecting to a second host via an indoor communication path, and is equipped with a 2.4 GHz A wireless communication circuit that can communicate in the frequency band, a wireless communication circuit that can communicate in the 5GHz frequency band, a wireless communication circuit that can communicate in the 6GHz frequency band, a network circuit that can connect to wired WAN and LAN, and a wireless communication circuit that can communicate in the 6GHz frequency band. The wireless communication circuit is configured so that all connected terminals of the wireless LAN repeater and the second host can communicate only in one of the 6 GHz band VLP and the 6 GHz band LPI. When the wireless LAN repeater requests the 6 GHz band When VLP is connected and the wireless LAN router is not connected to the second host via 6GHz band LPI, switch the 6GHz band communication from LPI to VLP.

Wireless LAN routers usually communicate with the second host using the 6GHz band LPI. At this time, the wireless LAN router configured to be able to communicate only with the wireless LAN repeater and all connected terminals of the second host in one of the 6 GHz band VLP and the 6 GHz band LPI cannot communicate with the wireless LAN connected via the outdoor communication path. Connect at 6GHz with a repeater.

However, when the wireless LAN router is not connected to the second host using the 6GHz LPI due to reasons such as the second host not having a wireless communication circuit capable of communicating in the 6GHz band, communication in the 6GHz band of the wireless LAN router is switched from Switching LPI to VLP can increase the communication capacity with wireless LAN repeaters.

In addition, in a wireless LAN router configured to be able to communicate only with the wireless LAN repeater and all connected terminals of the second host in one of the 6 GHz band VLP and the 6 GHz band LPI, if you want to give priority to adding wireless LAN routers, If the communication capacity of the router and wireless LAN repeater is limited, all 6GHz band communications including communications with the second host can be set as VLP.

In addition, when the wireless LAN repeater also has the room mode, the notification of the connection via the outdoor communication path can be received from the wireless LAN repeater, but the connection with the wireless LAN repeater is generally not known. Whether via outdoor communication path. At this time, the MAC address of the terminal via the outdoor communication path may be input when starting the wireless LAN router.

(12) The wireless LAN system of the twelfth invention is composed of the wireless LAN router and the second host of the eighth to eleventh inventions, the wireless LAN repeater from one aspect to the seventh invention, and the first host, which are arranged in a compartment. Both the wireless LAN router and the wireless LAN repeater are set to the private room mode and are connected via the outdoor communication path. The wireless LAN router is connected to the second host via the indoor communication path, and the wireless LAN repeater is connected to the second host via the indoor communication path. 1 host connection.

When the wireless LAN router or wireless LAN repeater has the room mode, there is no possibility of affecting the satellite communication system and weather radar by setting the wireless LAN router or wireless LAN repeater to the room mode. It will violate laws and regulations and can constitute a communication system with the maximum communication capacity.

It should be noted that, as described in Figure 16, the main house and wing rooms refer to the situation where a residence generally consists of two or more independent buildings. The main building is equivalent to the main house, and the smaller one is equivalent to the main house. The building is equivalent to a wing. However, in this specification, among two or more independent buildings, regardless of the scale of the building, the building where the wireless LAN router is installed is the main building.

However, when both the wireless LAN router and the wireless LAN repeater have the private room mode, by setting both the wireless LAN router and the wireless LAN repeater to the private room mode, further, the following effects can be obtained.

1) When the wireless LAN router and the wireless LAN repeater communicate in the 5GHzW56 band or the 2.4GHz band, the wireless LAN repeater sends a connection request for the 6GHz band VLP to the wireless LAN router, and the wireless LAN router By accepting the connection request, if the wireless LAN router can perform LPI/VLP connection to each terminal, or if there is no other terminal connected via 6GHz LPI, the 6GHz band VLP connection can be performed.

2) The wireless LAN repeater can send identification information indicating that the wireless LAN repeater is connected via an outdoor communication path to the wireless LAN router. The wireless LAN router does not allow unauthorized communication via outdoor communication with the wireless LAN repeater. Path communication uses 6GHz band LPI, 5GHz W52 band, and W53 band communications, so legal violations can be eliminated more reliably.

It should be noted that the above 1) and 2) are not standard functions of the wireless LAN system, but are independent functions.

(13) The wireless LAN system of the thirteenth invention. In the wireless LAN system of the twelfth invention, the wireless LAN router and the wireless LAN repeater each have a plurality of SSIDs, and the SSID of the connection between the wireless LAN router and the second host is the same as the wireless LAN router. The SSID connected to the repeater and the first host is the same SSID, and the SSID connected to the wireless LAN router and the wireless LAN repeater may be different from the same SSID.

At this time, since the first host and the second host are set to the same SSID, the wireless LAN connection can be continued even if the host (for example, a smartphone) used in the main room moves to the guest room. In addition, since the SSID of the connection between the wireless LAN router and the wireless LAN repeater is different from that of the connection between the wireless LAN router or the wireless LAN repeater and the host, the connection between the wireless LAN router and the wireless LAN repeater must be different. The connection is set to the communication most suitable for outdoor communication (such as VLP), and the connection between the wireless LAN router or wireless LAN repeater and the host can be matched to the communication most suitable for indoor communication (such as LPI).

(14) The wireless LAN system of the fourteenth invention. In the wireless LAN system of the twelfth invention, the wireless communication circuit of the 5 GHz band of the wireless LAN repeater has a radar wave detection circuit, and the wireless LAN repeater detects the radar wave of the 5 GHz W56 band. In the case of radio waves, the wireless LAN repeater transmits the radar radio wave detection information to the wireless LAN router, and the wireless LAN router determines that the radar radio wave has been detected.

In the wireless LAN system of the twelfth invention, the wireless LAN router may be placed at a location far away from the outer wall, such as in the center of the main room, and the wireless LAN repeater may be placed near the outer wall of the side room. In this case, the radar wave detection circuit of the wireless LAN router does not detect radar waves, but the radar wave detection circuit of the wireless LAN repeater can also detect radar waves.

In the wireless LAN system of the fourteenth invention, when the wireless LAN repeater detects the radio wave of the radar in the 5 GHz W56 band, the wireless LAN repeater transmits the radar radio wave detection information to the wireless LAN router, thereby wirelessly The LAN router can reliably terminate the use of the channel when radar waves arrive.

It should be noted that the radar wave detection information transmission function is not a standard function of the wireless LAN system, but a separate function.

(15) The wireless LAN system of the fifteenth invention is composed of a wireless LAN router and a second wireless LAN repeater arranged in the main room, and a first wireless LAN relay arranged in any one of the first to seventh inventions in the side room. The second wireless LAN repeater and the wireless LAN router are connected through the indoor communication path. The first wireless LAN repeater is set to the private room mode and communicates with the second wireless LAN router via the outdoor communication path. While the relay is connected, it is connected to the first host through the indoor communication path.

In this case, by providing the wireless LAN router and the second wireless LAN repeater in the main room, it is possible to communicate with a wider range and a larger number of hosts arranged in the same main room.

(16) The wireless LAN system of the 16th invention includes a wireless LAN router according to any one of the eighth to eleventh inventions arranged in the main room, and a first wireless LAN router according to any one of the first to seventh inventions arranged in the side room. A repeater, a third wireless LAN repeater, and a first host are configured. The wireless LAN router and the first wireless LAN repeater are set to a private room mode and are connected via an outdoor communication path. The third wireless LAN repeater is The device is connected to the first wireless LAN repeater through the indoor communication path and is connected to the first host through the indoor communication path.

In this case, by providing the first wireless LAN repeater and the third wireless LAN repeater in the private room, it is possible to communicate with a wider range and a greater number of hosts arranged in the same private room.

(17) The wireless LAN system of the 17th invention includes the wireless LAN router of the 8th to 11th inventions arranged in the main room, and the 4th wireless LAN repeater of any one of the 7th invention to the 1st side room arranged on one side of the first wing. , the first wireless LAN repeater and the first host computer according to any one of the inventions to the seventh invention are arranged on one side of the second room, and the wireless LAN router and the fourth wireless LAN repeater are set to the room mode. , connected via the outdoor communication path, the first wireless LAN repeater is set to the room mode, connected to the fourth wireless LAN repeater via the outdoor communication path, and simultaneously connected to the first host via the indoor communication path.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same parts are labeled with the same drawing symbols. In addition, in the case of the same schema mark, their names and functions are also the same. Therefore, their detailed description will not be repeated.

[Wireless LAN System 1000]

FIG. 1 is a schematic structural diagram of a wireless LAN system 1000 composed of a wireless LAN router 200, a wireless LAN repeater 100, and hosts 300 and 300a. In FIG. 1 , the wireless LAN router 200 is arranged in the first building (hereinafter referred to as the main room 400 ), and the wireless LAN repeater 100 is arranged in the second building (hereinafter referred to as the wing room 500 ). In the present embodiment, the main room 400 is equipped with an ONU (Optical Optical Network Unit) of an optical link and has an environment capable of wired Internet connection, while the side room 500 does not have a wired Internet environment. Furthermore, the first host computer 300 located in the side room 500 cannot directly communicate with the wireless LAN router 200 of the main room 400, or even if it can be connected, the radio wave is weak, the connection is unstable, and sufficient communication speed cannot be obtained. It should be noted that the hosts 300 and 300a are, for example, personal computers, printers, smartphones, etc. equipped with wireless LAN.

The wireless LAN router 200 and the wireless LAN repeater 100 are located in different buildings, and therefore communicate via the outdoor communication path 600. The wireless LAN router 200 and the second host 300a, and the wireless LAN repeater 100 and The first host computer 300 is arranged inside the same building, and therefore communicates via the indoor communication path 700 .

When using frequencies in the 6GHz band for wireless LAN, LPI with an equivalent isotropically radiated power (EIRP) of up to 200mW and VLP with an EIRP of up to 25mW can be used indoors, but only outdoors with an EIRP of up to 25mW. 25mW VLP.

On the other hand, in the 5GHz band, the W56 band can only be used outdoors, and there is a restriction that it must move to another channel when radar waves are detected.

The wireless LAN repeater 100 and the wireless LAN router 200 constituting the wireless LAN system 1000 reliably comply with the restrictions based on the above-mentioned laws and regulations, and are designed to ensure that the wireless LAN router 200 and the wireless LAN repeater 100 and the wireless LAN The communication capacity (speed) between the repeater 100 and the first host 300 is maximized.

[Wireless LAN repeater 100 according to the first embodiment]

FIG. 2 is a schematic block diagram of the wireless LAN repeater 100 according to the first embodiment.

As shown in FIG. 2 , the wireless LAN repeater 100 includes a 2.4 GHz band wireless communication circuit 10 , a 5 GHz band wireless communication circuit 20 , a 6 GHz band wireless communication circuit 30 , a control circuit 40 and a data cache 50 . In addition, the 2.4GHz frequency band wireless communication circuit 10, the 5GHz frequency band wireless communication circuit 20, and the 6GHz frequency band wireless communication circuit 30 are equipped with antennas 11, 21, and 31 respectively. The 2.4GHz frequency band and the 5GHz frequency band can also be inserted between the antennas and the wireless communication circuit. Antenna switch (not shown) to share the antenna. The 5GHz band wireless communication circuit 20 includes a radar wave detection circuit 22 .

The radar wave detection circuit 22 is used for a DFS function that monitors the radio waves of the radar when the wireless LAN repeater 100 communicates with the first host 300 in the 5 GHz W53 and W56 frequency bands. In the case of radio waves, transfer to other channels or other frequency bands.

Since the wireless LAN repeater 100 is connected to the wireless LAN router 200 via the outdoor communication path 600, it is considered that the radio waves transmitted by the wireless LAN repeater 100 leak outdoors. Therefore, for example, when the wireless LAN repeater 100 is connected to the wireless LAN router 200 through the 6 GHz band VLP and the radio wave of the radar in the 5 GHz W56 band arrives, the wireless LAN repeater 100 communicates with the first host through the 5 GHz W56 band. 300 connections may be against the law. When the radar wave detection circuit 22 of the 5 GHz band wireless communication circuit 20 of the present invention detects the radar wave, the wireless LAN repeater 100 does not detect the radar during the non-occupancy period during communication with the host 300 . Communicate on the radio wave channel to nip the possibility of violating laws before they happen. It should be noted that the non-occupancy period (NOP: Non-Occupancy Period) refers to the period during which the channel cannot be used when the radar wave is detected, for example, 30 minutes.

In the case where there is one wireless communication circuit, only one channel can communicate in the 2.4GHz frequency band, the 5GHz frequency band and the 6GHz frequency band respectively. Therefore, for example, when the communication between the wireless LAN router 200 and the wireless LAN repeater 100 (hereinafter also referred to as backhaul) is performed on one channel in the 2.4 GHz band, the communication between the wireless LAN router 200 and the host 300 Communication can be carried out on the same channel as the backhaul in the 2.4GHz band, any channel in the 5GHz band, and any channel in the 6GHz band, but communication cannot be carried out in a different channel from the backhaul in the 2.4GHz band. This is to limit the communication channel in each frequency band of the wireless LAN repeater 100 to one and to simplify the circuit of the wireless LAN repeater 100 . However, by having two wireless communication circuits in the 5GHz band, it is also possible to set the backhaul to W56 and the connection to the host to W52 or W53.

The control circuit 40 controls each wireless communication circuit based on the flow chart described below, and at the same time, temporarily stores the information of the received data packet in the data cache 50, reorganizes it, and sends it to the specified transmission destination again.

(Flowchart of the first embodiment)

FIGS. 3 , 4 , and 5 are schematic flowcharts showing operations when the wireless LAN repeater 100 according to the first embodiment is activated. 3 is a flowchart in a case where the wireless LAN repeater 100 can select LPI and VLP for each terminal (the wireless LAN router 200 and the first host 300 ) in communication in the 6 GHz band. In addition, FIG. 4 and FIG. 5 are flowcharts in the case where the wireless LAN repeater 100 cannot select LPI and VLP for each terminal for communication in the 6 GHz band. FIG. 4 is a flow chart when communicating with the wireless LAN router. 200 (when connecting to the wireless LAN router 200 through VLP, and not connecting to the first host 300 through LPI). Flowchart of the case when the host 300 is connected and is not connected to the wireless LAN router 200 via 6GHz).

In addition, FIG. 6 shows a case where the wireless LAN repeater 100 is connected to the wireless LAN router 200 through the 6GHz band VLP and can be connected through the 5GHzW56 band, or when the wireless LAN repeater 100 is connected through the 5GHzW56 band and can be connected through the 6GHz band VLP. Flow chart for re-selecting the most suitable communication environment.

It should be noted that as a method of selecting LPI and VLP for each terminal to communicate, it is also possible to select LPI and VLP every time communication with the terminal is started. For example, the wireless LAN repeater 100 has multiple SSIDs (Service Set Identifier: Service Set Identifier), you can also make the terminals communicating through LPI and the terminals connecting through VLP belong to different SSIDs.

Hereinafter, the operation of the wireless LAN repeater 100 when activated will be described based on each figure.

(Explanation of the flow chart in Figure 3)

FIG. 3 is a flowchart in a case where the wireless LAN repeater 100 can select LPI and VLP for each terminal (the wireless LAN router 200 and the first host 300 ) in communication in the 6 GHz band.

When starting up, the wireless LAN repeater 100 of the first embodiment first checks whether the SSID of the 6 GHz band from the wireless LAN router 200 can be detected (step S1 ).

When the SSID of the 6 GHz band is detected, it is confirmed whether the wireless LAN router 200 can be connected through the 6 GHz band VLP (step S2).

If the connection can be made through the 6GHz frequency band VLP, it is further confirmed whether the connection can also be made through the 5GHz W56 frequency band (step S3).

When both the 6GHz band VLP and the 5GHzW56 band can be connected to the wireless LAN router 200, the most suitable communication environment among the 6GHz band VLP and the 5GHzW56 band is selected and connected to the wireless LAN router 200 (step S5). It should be noted that the selection of the most appropriate communication environment is judged based on, for example, the size of the communication capacity, error rate, etc.

In step S3, if the connection cannot be made through the 5 GHz W56 band, it is confirmed whether the connection with the wireless LAN router 200 is disconnected in the 2.4 GHz band (step S4).

When both the 6GHz band VLP and the 2.4GHz band can be connected to the wireless LAN router 200, the most suitable communication environment among the 6GHz band VLP and the 2.4GHz band is selected and connected to the wireless LAN router 200 (step S6).

In step S4, if the connection cannot be made through the 2.4 GHz band, the wireless LAN router 200 is connected through the 6 GHz band VLP (step S7).

After the connection with the wireless LAN router 200 is completed, the SSIDs of the 6 GHz band LPI, the 5 GHz band and the 2.4 GHz band are sent to the first host 300 and connected to the first host 300 according to the request of the first host 300 . It should be noted that in the frequency band connected to the wireless LAN router 200, the connection to the wireless LAN router 200 and the connection to the first host 300 must be on the same channel.

It should be noted that when comparing the communication environment of the 6GHz band VLP with the 5GHzW56 band or the 2.4GHz band, the communication environment of the 6GHz band VLP with the original bandwidth should be the best, but the EIRP of the 6GHz band VLP is small. According to the wireless LAN router 200 The communication environment of the 5GHzW56 band or the 2.4GHz band may be better depending on the distance from the wireless LAN repeater 100 and whether there are obstacles in the way.

In step S2, if the connection cannot be made through the 6 GHz band VLP, it is confirmed whether the wireless LAN repeater 100 can be connected to the wireless LAN router 200 through the 5 GHz W56 band (step S9).

If the connection is possible through the 5GHz W56 band, the wireless LAN router 200 is connected through the 5GHz W56 band (step S11).

In step S9, if the connection cannot be made through the 5GHz W56 frequency band, it is confirmed whether the connection can be made through the 2.4GHz frequency band (step S10).

If the connection is possible through the 2.4 GHz frequency band, the wireless LAN router 200 is connected through the 2.4 GHz frequency band (step S12).

In step S10, if connection cannot be made even through the 2.4GHz frequency band, the process returns to step S1 again. At this time, you can also set the delay time until restarting, the maximum number of repetitions when starting again, etc.

After the connection with the wireless LAN router 200 is completed, the SSIDs of the 6 GHz band LPI, the 5 GHz band and the 2.4 GHz band are sent to the first host 300 and connected to the first host 300 according to the request of the first host 300 .

After connecting to the first host 300 , the wireless LAN repeater 100 can request the wireless LAN router 200 to change from the 6 GHz band LPI to the 6 GHz band VLP (or add a 6 GHz band VLP) (step S14 ).

Then, if the connection can be made through the 6GHz band VLP, return to step S3, select the most suitable communication environment among the 6GHz band VLP, the 5GHzW56 band, and the 2.4GHz band, and reconnect with the wireless LAN router 200 (step S15).

This function is effective in the case where the wireless LAN router 200 is capable of connecting via the 6GHz band VLP but the SSID of the 6GHz band VLP is not transmitted. However, since this function is not a standardized function of wireless LAN, the wireless LAN router 200 also needs to have a private room mode (stand-alone function). This function will be explained again based on FIG. 10 .

In step S1, if the SSID of the 6 GHz band cannot be detected from the wireless LAN router 200, the connection of the 5 GHz W56 band is confirmed (step S16). If the connection can be made through the 5 GHz W56 band, the connection is made through the 5 GHz W56 band (step S18). . If the connection cannot be made through the 5GHzW56 frequency band, the connection through the 2.4GHz frequency band is confirmed (step S17). If the connection can be made through the 2.4GHz frequency band, the connection is made through the 2.4GHz frequency band (step S19).

In step S17, if connection cannot be made even through the 2.4GHz frequency band, the process returns to step S1 again. At this time, you can also set the delay time until restarting, the maximum number of repetitions when starting again, etc.

After the connection with the wireless LAN router 200 is completed, the SSIDs of the 6 GHz band LPI, the 5 GHz band and the 2.4 GHz band are sent to the first host 300 and connected to the first host 300 according to the request of the first host 300 .

In the frequency band connected to the router, the connection to the router and the connection to the host are on the same channel.

(Explanation of the flow chart in Figure 4)

FIG. 4 shows the relationship between the wireless LAN repeater 100 and the wireless LAN router 200 when the wireless LAN repeater 100 cannot select LPI and VLP for communication with each terminal (the wireless LAN router 200 and the first host 300 ). A flow chart in the case of connection priority (when connecting to the wireless LAN router 200 through VLP, not connecting to the first host 300 through LPI). It should be noted that in FIG. 4 , steps with the same numbers as in FIG. 3 represent the same operations as in FIG. 3 .

In the flowchart of FIG. 4 , after the connection method with the wireless LAN router 200 is determined in S3 to S7, it is confirmed whether the wireless LAN router 200 is connected through the 6GHzVLP (step S8a), and then the wireless LAN router 200 is connected through the 6GHzVLP. 200 is connected, the first host 300 is not connected through the 6GHz LPI (step S8c), and when the wireless LAN router 200 is not connected through the 6GHz band VLP, the first host 300 is connected through the 6GHz LPI (step S8b). A bit different.

In step S8a, the wireless LAN repeater 100 is connected to the wireless LAN router 200 through the 6GHz VLP, which means that the connection environment between the wireless LAN repeater 100 and the wireless LAN router 200 is optimal. Therefore, in the case of downloading a large amount of data from the Internet, etc., even if the connection between the wireless LAN repeater 100 and the first host 300 is set to the 6GHz band VLP, the wireless LAN repeater 100 and the first host 300 The communication capacity is reduced, and overall it is considered more preferable.

In the frequency band connected to the router, the connection to the router and the connection to the host are on the same channel.

(Explanation of the flow chart in Figure 5)

FIG. 5 shows the connection between the wireless LAN repeater 100 and the first host 300 when the wireless LAN repeater 100 cannot select LPI and VLP for communication with each terminal (the wireless LAN router 200 and the first host 300 ). A flow chart in the case of priority (when connecting to the first host 300 via LPI and not connecting to the wireless LAN router 200 via 6 GHz). It should be noted that in FIG. 5 , steps with the same numbers as in FIG. 3 represent the same operations as in FIG. 3 .

When the first hosts 300 exchange a large amount of data and the like via the wireless LAN repeater 100, the flow chart of FIG. 5 that prioritizes the connection with the first host 300 is preferable to the flow chart of FIG. 4 .

In the flowchart of FIG. 5 , after the connection method with the wireless LAN router 200 is determined in S3 to S7, it is confirmed whether there is a connection request from the first host 300 to the 6GHz band LPI (step S7a).

When there is a connection request for the 6GHz band LPI, it is confirmed whether the wireless LAN router 200 is connected to the 6GHz band VLP (step S7b).

When connecting to the wireless LAN router 200 through the 6GHz band VLP, the connection to the 5GHzW56 band is confirmed (step S7c). If the connection can be made through the 5GHzW56 band, the connection is switched to the 5GHzW56 band (step S7d). If the connection cannot be made through the 5GHzW56 band, the connection is switched to the 5GHzW56 band (step S7d). If the frequency band is connected, switch to the 2.4GHz frequency band (step S7e).

Then, according to the request of the first host 300, any one of the 6 GHz band LPI, the 5 GHz W56 band, and the 2.4 GHz band is passed to the first host 300 (step S8d).

On the other hand, in step S7a, when there is no connection request through the 6GHz band LPI from the first host 300, based on the request from the first host 300, the connection with the first host is made through either the 5GHz W56 band or the 2.4GHz band. 300 connection (step S8e).

In the frequency band connected to the router, the connection to the router and the connection to the host are on the same channel.

(Explanation of the flow chart in Figure 6)

FIG. 6 shows a case where the wireless LAN repeater 100 is connected to the wireless LAN router 200 via a 6GHz band VLP so that the connection is possible in the 5GHz W56 band, or a case where the wireless LAN repeater 100 is connected through the 5GHz W56 band so that the connection is possible in the 6GHz band VLP. , the flow chart when re-selecting the most suitable communication environment.

In FIG. 6 , when the wireless LAN repeater 100 is not connected to the wireless LAN router 200 through the 6GHz band VLP (step S31 ), it is confirmed whether the connection can be made through the 6GHz band VLP (step S32 ). If the connection can be made, , then according to the flowcharts of FIGS. 3 to 5 , the wireless LAN repeater 100 is restarted from step S1 (step S35 ).

In step S32, if the connection cannot be made through the 6GHz band VLP and the connection cannot be made through the 5GHzW56 band (for example, when the connection is made through 2.4GHz) (step S33), it is confirmed whether the connection can be made through the 5GHzW56 band (step S34). If If the connection is possible, restart the wireless LAN repeater 100 (step S35)

In other cases, the wireless LAN repeater 100 continues the current state.

It should be noted that if this action of re-selecting the most suitable communication environment is performed frequently, the connection between the wireless LAN repeater 100 and the wireless LAN router 200 and the connection between the wireless LAN repeater 100 and the third 1. The connection of the host 300 is chaotic, so it is preferable to stay for a predetermined time interval, for example, about once every 30 minutes.

[Wireless LAN router 200 of the second embodiment]

FIG. 7 is a schematic block diagram of the wireless LAN router 200 according to the second embodiment.

As shown in FIG. 7 , the wireless LAN router 200 includes a 2.4GHz band wireless communication circuit 10a, a 5GHz band wireless communication circuit 20a, a 6GHz band wireless communication circuit 30a, a control circuit 40a, a data cache 50a, and a network circuit 60. In addition, the 2.4GHz band wireless communication circuit 10a, the 5GHz band wireless communication circuit 20a, and the 6GHz band wireless communication circuit 30a include antennas 11a, 21a, and 31a respectively. The 2.4GHz band and the 5GHz band can also share an antenna by inserting an antenna switch (not shown) between the antenna and the wireless communication circuit. The 5GHz band wireless communication circuit 20a includes a radar wave detection circuit 22a.

It should be noted that the wireless LAN router 200 of the second embodiment is a base device of the wireless LAN and also includes a wireless LAN access point that does not have a router function. However, when the wireless LAN router 200 is a wireless LAN access point, the network circuit 60 may not be provided.

The radar radio wave detection circuit 22a is used for a DFS function that monitors radar radio waves when the wireless LAN router 200 communicates with the wireless LAN repeater 100 and the second host 300a in the 5 GHz W53 and W56 frequency bands. , when the radio wave of the radar is detected, it is transferred to other channels or other frequency bands.

Furthermore, the wireless LAN router 200 is provided with a WAN side connection terminal 61 and a LAN side connection terminal 62. The WAN side connection terminal 61 is connected to the Internet via an ONU or the like of an optical link.

(Flowchart of the second embodiment)

Figures 8 and 9 are both flowcharts when the wireless LAN router 200 is started in the private room mode. Figure 8 is a flowchart when the wireless LAN router 200 has the function of setting LPI/VLP for each connected terminal. Figure 9 This is a flowchart when the wireless LAN router 200 cannot set LPI/VLP for each connected terminal.

Hereinafter, the operation of the wireless LAN router 200 when started is explained based on each figure.

(Explanation of the flow chart in Figure 8)

When the wireless LAN router 200 in the private room mode is started, first, the MAC address of the wireless LAN repeater 100 located in the private room 500 and connected via the outdoor communication path 600 is specified (step S41). However, when the wireless LAN repeater 100 is also set to the private room mode, the identification information may be received from the wireless LAN repeater 100 .

Next, the wireless LAN router 200 outputs the SSIDs of the 6 GHz band LPI, the 6 GHz band VLP, the 5 GHz W56 band, and the 2.4 GHz band (step S42).

Next, there is a connection request through the 6 GHz band LPI from any one of the wireless LAN repeater 100 and the second host 300a, and the terminal that issued the connection request is not for wireless LAN in the room 500 connected via the outdoor connection path. In the case of the relay 100, connection via the 6GHz band LPI is allowed (steps S43 to S45).

Next, when there is a connection request through the 6 GHz band VLP from any of the connection terminals (step S46), the connection through the 6 GHz band LPI is allowed (step S47).

Furthermore, when there is a connection request through the 5GHz W56 band from any one of the connection terminals (step S48), the connection through the 5GHz W56 band is allowed (step S49), and if there is a connection request through the 2.4GHz band from any one of the connection terminals. In this case (step S50), the connection through the 2.4GHz band is allowed (step S51).

It should be noted that the wireless LAN router 200 is connected to the second host 300a using the W56 frequency band in 5 GHz in order to be able to use a multi-channel wireless network that can simultaneously utilize multiple frequency bands when connecting to WiFi 7 and the like that are expected to be put into practical use in the future. In the case of link operation (MLO), the 5 GHz band and the 6 GHz band can be used simultaneously for connection between the wireless LAN router 200 and the wireless LAN repeater 100 . Therefore, when MLO is not used, the connection between the wireless LAN router 200 and the wireless LAN repeater 100 does not use the 5GHzW56 frequency band, or the wireless LAN repeater 100 has two wireless communication circuits in the 5GHz band. When W56, W52, and W53 can communicate, communication in the 5GHz band does not need to be limited to the W56 band.

In addition, when the wireless LAN router 200 does not have a connection terminal connected via an outdoor connection path such as the wireless LAN repeater 100, by starting the wireless LAN router 200 in the normal mode, it is possible to communicate with the second host through all frequency bands. 300a connection.

The repeater also automatically obtains the repeater's MAC address in room mode.

(Explanation of the flow chart in Figure 9)

FIG. 9 is a flowchart when the wireless LAN router 200 cannot set LPI/VLP for each connected terminal. Therefore, only when the wireless LAN router 200 is not connected to the second host 300 a through the 6 GHz band LPI, it can be connected to the wireless LAN repeater 100 through the 6 GHz band VLP. It should be noted that in FIG. 9 , steps with the same numbers as in FIG. 8 represent the same operations as in FIG. 8 .

At this time, since the initially sent SSID does not include the SSID of the 6GHz band VLP (step S42a), when it is known that the 6GHz band VLP is not used (step S43 is No, or step S44 is Yes), the 6GHz band VLP is retransmitted. SSID (step S42b), and when there is a connection request through the 6GHz band VLP from any connected terminal (step S46), the connection through the 6GHz band VLP is allowed (step S47).

Steps S48 to S51 are the same as in FIG. 8 .

The repeater also automatically obtains the repeater's MAC address in room mode.

[Wireless LAN System 1000]

The structure of the wireless LAN system 1000 is shown in FIG. 1 .

Since the wireless LAN router 200 and the wireless LAN repeater 100 are arranged in different buildings, communication is performed via the outdoor communication path 600. The wireless LAN router 200, the second host 300a, and the wireless LAN repeater 100 Since they are arranged inside the same building as the first host computer 300, they communicate via indoor communication paths 700a and 700 respectively.

Even when only the wireless LAN repeater 100 or only the wireless LAN router 200 is set to the private room mode, the object of the present invention can be achieved to constitute a communication system that does not violate laws and regulations and has a maximum communication capacity. However, When both the wireless LAN router 200 and the wireless LAN repeater 100 are set to the private room mode, the effect can be further improved.

Here, as an operation when both the wireless LAN router 200 and the wireless LAN repeater 100 are set to the private room mode, based on FIG. The case of LPI handover request to 6GHz band VLP is explained. In addition, a case where the wireless LAN repeater 100 and the wireless LAN router 200 perform communication operations during radar wave detection will be described based on FIGS. 11 and 12 .

(Handover request and response from 6GHz band LPI to 6GHz band VLP)

FIG. 10 is a flowchart illustrating the operation when the wireless LAN repeater 100 issues a switching request from the 6 GHz band LPI to the 6 GHz band VLP to the wireless LAN router 200 .

When the wireless LAN router 200 is connected to the wireless LAN repeater 100 in the 5 GHz W56 band or the 2.4 GHz band (step S51 ), when the wireless LAN router 200 receives the 6 GHz band VLP from the wireless LAN repeater 100 Upon request for change (step S52), the wireless LAN router 200 checks whether the 6 GHz frequency band can be changed to the VLP (step S53). Generally, if the wireless LAN router 200 is not connected to the second host 300a via the 6GHz band LPI, it can be changed to VLP.

When the 6 GHz frequency band can be changed to the VLP, the 6 GHz frequency band is changed to the VLP (step S54), and OK is returned to the wireless LAN repeater 100 (step S55). The repeater 100 replies NG (step S56).

It should be noted that this flowchart is a flowchart when the wireless LAN router 200 cannot set the 6GHz band VLP/LPI for each terminal. However, the wireless LAN router 200 can set the 6GHz band VLP/LPI for each terminal. In this case, step S53 always returns "YES", and the wireless LAN router 200 adds the 6GHz band VLP (transmits the SSID including the 6GHz band VLP), and simply replies OK to the wireless LAN repeater 100 .

By having this function, the wireless LAN system 1000 enables the wireless LAN router 200 and the wireless LAN repeater 100 to be connected by the 6 GHz band VLP, such as when the second host 300 a does not communicate through the 6 GHz band LPI. Reliably connecting via the 6GHz band VLP can increase the communication capacity of the wireless LAN router 200 and the wireless LAN repeater 100 .

(Contact action during radar wave detection)

Regarding the communication between the wireless LAN router 200 and the wireless LAN repeater 100, when the radar wave detection circuit 22a provided in the wireless LAN router 200 detects the radar wave, the wireless LAN router 200 communicates with the wireless LAN router 200. In the communication between the LAN repeater 100 and the second host 300a, the possibility of violating laws is nipped in the bud by not communicating on the radio wave channel where radar is detected during the non-occupancy period. However, there are cases where the wireless LAN router 200 is placed far away from the outer wall of the main room 400 and the wireless LAN repeater 100 is placed near the outer wall of the side room 500 . In this case, the radar wave detection circuit 22a of the wireless LAN router 200 cannot detect the radar wave. On the other hand, the radar wave detection circuit 22 of the wireless LAN repeater 100 may detect the radio wave.

In the wireless LAN system 1000 of the present invention, when both the wireless LAN router 200 and the wireless LAN repeater 100 are set to the private room mode, in order to prevent the DFS function from violating laws and regulations in this case, the following steps are performed: 11 or the action shown in Figure 12.

In Figure 11, the left side shows the situation where the repeater detects the radar, and the right side shows the situation where the router detects the radar. In FIG. 11 , when the radar wave detection circuit 22 of the wireless LAN repeater 100 detects a radar wave (step S61 ), the wireless LAN repeater 100 transmits the radar wave detection information to the wireless LAN router 200 (Step S62).

When the radio wave detection information of the radar is transmitted from the wireless LAN repeater 100 or when its own radar wave detection circuit 22a detects radio waves (step S63), the wireless LAN router 200 stops being in use. Communication in the channel of the 5GHzW56 frequency band (step S64), and confirming the connection on the other channel of the 5GHzW56 frequency band (step S65). Specifically, search for a channel where no radar wave is detected for more than 1 minute and a wireless LAN with other SSID has a small radio wave.

When it is possible to connect on another channel of the 5GHz W56 band (step S66), connect to the wireless LAN repeater 100 on that channel (step S67). If it is not possible, in order to find a wireless LAN router 200 and the wireless LAN repeater 100, the wireless LAN repeater 100 and the wireless LAN router 200 are restarted from step S1 and steps S42 to S42a respectively (step S68).

However, when the wireless LAN repeater 100 is restarted, "Are you connected via the 5 GHz W56 band?" in step S3 and step S9 is "No". In addition, when the wireless LAN router 200 is restarted, the SSID of the 5 GHz W56 band is not output in steps S42, S42a, and S42b.

In Figure 12, the left side shows the situation where the repeater detects the radar, and the right side shows the situation where the router detects the radar. In FIG. 12 , after stopping communication on the 5 GHz W56 band channel used in step S64 due to radar detection, etc., the wireless LAN router 200 first connects to the wireless LAN repeater 100 at 6 GHz (VLP) or 2.4 GHz. (Step S71). Then, the wireless LAN router 200 maintains the communication in step S71 and investigates the possibility of connection on another channel in the 5 GHz W56 band (step S72 ). Specifically, search for another channel where no radar wave is detected for more than 1 minute and the radio wave of the wireless LAN of the other SSID is small.

When the connection is possible on another channel of the 5 GHz W56 band (step S73), the wireless LAN router 200 switches the connection with the wireless LAN repeater 100 to another channel of the 5 GHz W56 band (step S74). If this is not possible, the connection to the wireless LAN repeater 100 is continued at 6 GHz or 2.4 GHz.

It should be noted that in step S74, FIG. 12 shows an example of switching to another channel of the W56 frequency band, but it is not limited to this. In order to find the most suitable combination of the wireless LAN router 200 and the wireless LAN repeater 100 In the communication environment, the wireless LAN repeater 100 and the wireless LAN router 200 can be restarted from step S1 and steps S42 to S42a respectively.

In the method in Figure 11, after stopping communication in the 5GHz W56 band in use, it is necessary to confirm that there are no radar waves on the other channel for at least 1 minute, so communication is stopped for at least 1 minute. On the other hand, in the method of FIG. 12 , it is necessary to temporarily connect to the wireless LAN repeater 100 at 6 GHz or 2.4 GHz, but it is advantageous in that it can avoid communication stoppage for at least one minute.

(Advantages of wireless band switching method in private room mode)

The wireless LAN router 200 disposed in the main room 400 and the wireless LAN repeater 100 disposed in the guest room 500 are connected via an outdoor communication path 600. The wireless LAN repeater 100 is connected to the wireless LAN repeater 100 disposed in the same guest room 500 via an indoor communication path 700. When one or more first hosts 300 are connected, the wireless LAN system 1000 of the present invention has the following advantages.

1) Since the 5GHz W52 band, W53 band, and 6GHz band LPI, which are prohibited for outdoor use, are not used in the connection between the wireless LAN router 200 and the wireless LAN repeater 100, there is no violation of laws and regulations.

2) Since the most suitable communication environment among the 6GHz band VLP and the 5GHz W56 band that allow communication outdoors is selected to connect to the wireless LAN router 200, it is possible to further increase the communication with the wireless LAN router 200. capacity.

3) When the radio wave of the radar is detected by the wireless LAN router 200 or the wireless LAN repeater 100 in the 5 GHz W56 band, either of the following two methods is used.

In the first method, first try to connect on another channel of the 5GHz W56 band, and if the connection fails, restart the wireless LAN router 200 and the wireless LAN repeater 100 . Therefore, it is possible to ensure reliable compliance with laws and regulations based on improved radar detection accuracy during radar detection and to suppress the processing load of the wireless LAN repeater 100 .

In the second method, first connect to the wireless LAN repeater 100 at 6 GHz or 2.4 GHz, and then try connection on another channel of the 5 GHz W56 band. Therefore, it is possible to achieve reliable compliance with laws and regulations based on improved radar detection accuracy during radar detection, and to avoid communication suspension of at least one minute required for radar detection.

4) By regularly trying to recover to the 6GHz frequency band VLP or 5GHzW56 frequency band with large communication capacity, the accumulated communication capacity can be increased.

It should be noted that the arrangement of the wireless LAN router 200 and the wireless LAN repeater 100 may be changed from the initial arrangement position. Therefore, it is preferable that the wireless LAN router 200 and the wireless LAN repeater 100 not only have a room mode, but also have a connection between the wireless LAN router 200 and the wireless LAN repeater 100 and a connection with the hosts 300 and 300a. Regular mode using all frequency bands of 2.4GHz band, 5GHz band, and 6GHz band.

In addition, it is preferable that the two modes can be switched between the two modes by a switch or the like that makes it clear in which mode the wireless LAN router 200 and the wireless LAN repeater 100 are used. At this time, from the viewpoint of preventing erroneous operation and ensuring clarity, the mode switching switch is preferably a slide switch provided on the side of the casing of the wireless LAN router 200 and the wireless LAN repeater 100 . In addition, the LED provided on the casing can indicate which mode communication is performed in, and can also indicate which frequency band the wireless LAN router 200 and the wireless LAN repeater 100 use for communication. Furthermore, by displaying the communication status (radio wave intensity, etc.) of the wireless LAN router 200 and the wireless LAN repeater 100 using LEDs or the like, it is possible to easily find the installation location most suitable for large-capacity high-speed communication.

In addition, in the wireless LAN system 1000 having the configuration of FIG. 1 , the wireless LAN router 200 and the wireless LAN repeater 100 each have a plurality of SSIDs, and the SSID connected to the wireless LAN router 200 and the second host 300 a is different from the wireless LAN router 200 . The SSID used for connection between the repeater 100 and the first host 300 is the same SSID. The SSID used for connection between the wireless LAN router 200 and the wireless LAN repeater 100 may be different from the same SSID.

At this time, since the same SSID is set for the first host 300 and the second host 300a, even if the second host 300a (for example, a smartphone) used in the main room 400 is moved to the side room 500, it can continue as it is. Wireless LAN connection.

In addition, since the connection between the wireless LAN router 200 and the wireless LAN repeater 100 is different from the SSID of the connection between the wireless LAN router 200 or the wireless LAN repeater 100 and the hosts 300 or 300a, for example, the wireless LAN router 200 can be connected to the wireless LAN router 200. The connection between the router 200 and the wireless LAN repeater 100 corresponds to the VLP, and the connection between the wireless LAN router 200 or the wireless LAN repeater 100 and the hosts 300 and 300a corresponds to the LPI.
