Technical Field

[0001] This invention relates to a wireless LAN repeater, a wireless LAN router, and a wireless LAN system equipped with a wireless LAN band switching method.

[0002] It should be noted that the wireless LAN router in this invention refers to the host of the wireless LAN, and also includes wireless LAN access points that do not have router functions. Background Technology

[0003] The following invention relates to a wireless communication device with a frequency band switching method for wireless LAN.

[0004] For example, Patent Document 1 (Japanese Patent Application Publication No. 2003-333640) discloses a method as follows: In a wireless communication device corresponding to multiple frequency bands such as the 5.2 GHz band and the 2.4 GHz band, a method is disclosed in which the control unit of the wireless communication device determines whether the device is indoors or outdoors, thereby enabling the legal selection of a communication frequency band. On a display terminal constituting a wireless communication system with a basic device, a detection antenna with high directional sensitivity is provided in one direction, oriented in a direction opposite to the direction of gravity. A detection signal is emitted from the detection antenna, and the reflected wave from a reflector based on this signal is received by the detection antenna and processed by a processing circuit. Based on the processing result, the control unit (CPU) determines whether the display terminal is indoors and selects a communication frequency band.

[0005] Furthermore, Patent Document 2 (Japanese Patent Application Publication No. 2015-192315) discloses a wireless communication device as follows: As a wireless communication device with relay function, based on a small and simple structure and a reliable determination means, it performs communication via a suitable frequency without using a frequency band prohibited by law, etc., and includes a first wireless communication unit that communicates with a connection destination using a first wireless signal according to a predetermined communication condition, a second wireless communication unit that communicates using a second wireless signal, a communication mode determination unit that determines whether a communication condition can be met and outputs the determination result, and a restriction unit that instructs the second wireless communication unit whether the use of a predetermined frequency band is permitted according to a predetermined permission or disallowance standard including the determination result.

[0006] Furthermore, Patent Document 3 (Japanese Patent Application Publication No. 2004-336351) discloses a warning method for using a wireless LAN device with the following features: a warning method for using a wireless LAN device that can transmit and receive even when using a frequency band that is prohibited under specified conditions, which detects whether the wireless LAN device is about to start communication using the frequency band that is prohibited under specified conditions, and if communication is about to start using the frequency band, issues a warning indicating that the use of the frequency band is prohibited under specified conditions.

[0007] Furthermore, Patent Document 4 (International Publication No. 2012 / 137908) discloses a wireless communication device as follows: a wireless communication device having the function of selecting a wireless communication method that adopts a frequency band that conforms to location information from different frequency bands to form a wireless service area, which uses a first wireless communication unit connected to an external network, and any one of a first frequency band and a second frequency band, respectively, and has a second wireless communication unit to form a service area that can be connected to an external network, a location information acquisition unit to acquire the location information of the device, and a selection unit to select any one of the first frequency band and the second frequency band based on the location information.

[0013] Patent Document 4: International Publication No. 2012 / 137908 Summary of the Invention

[0014] In recent years, 2.4GHz and 5GHz frequency bands have been used in wireless LANs. Furthermore, within the 5GHz band, W52 (5.2GHz), W53 (5.3GHz), and W56 (5.6GHz) frequencies are available. Meanwhile, devices with communication capabilities across all frequencies (2.4GHz, W52, W53, and W56) are widely available in routers, repeaters (communication devices that connect routers and hosts), and computers that incorporate wireless LAN communication functions.

[0015] However, the 5.2 GHz band overlaps with the feeder link frequency of satellite communication systems. In addition, the 5.3 GHz and 5.6 GHz bands do not overlap with or are adjacent to weather radar frequencies. Therefore, usage restrictions are imposed on each frequency band in home wireless LANs.

[0016] Recently, there has been a global effort to utilize the 6GHz frequency band for wireless LANs. In the United States, U-NII5 (5.925-6.425GHz) and U-NII7 (6.525-6.875GHz) have been permitted for use as Standard Power APs (for outdoor communication) and Low Power APs (for indoor communication only). Additionally, U-NII6 (6.425-6.525GHz) and U-NII8 (6.875-7.125GHz) are permitted for use exclusively as Low Power APs. Furthermore, research is underway on Very Low Power APs with even lower output power.

[0017] On September 2, 2022, Japan also issued and implemented a new ministerial ordinance regarding the introduction of 6GHz band wireless LANs, defining a new frequency band (5925MHz to 6425MHz) for low-power data communication systems. The new ordinance specifies that radios usable indoors must have an equivalent isotropic radiated power (EIRP) of at most 200mW (Low Power Indoor), while radios usable both indoors and outdoors must have an EIRP of at most 25mW (Very Low Power).

[0018] Table 1 below shows the current constraints for each frequency band as of September 2022.

[0019] Table 1

[0020] Usable locations 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 6GHz LPI Indoor only unnecessary

[0021] As shown in Table 1, the 2.4GHz band and the W56 band can be used both indoors and outdoors, while the W52 band and the W53 band can only be used indoors.

[0022] Furthermore, Dynamic Frequency Selection (DFS) is a requirement in wireless LAN devices to avoid adverse effects on C-band radar primarily used for meteorological observation. It mandates the detection of radar waves and the cessation of transmission during detection (as well as the relocation to other channels). DFS functionality is mandatory in the W53 and W56 bands.

[0023] For the 6GHz band, VLP can be used both indoors and outdoors, but LPI can only be used indoors.

[0024] Recently, as a method of utilizing wireless LAN, such as Figure 16The described method involves configuring a router in the main room and placing a repeater in the side room. Communication between the router and the repeater is achieved via wireless LAN. Furthermore, communication between the repeater and the host computer located in the side room is also achieved via wireless LAN.

[0025] At this point, since the communication path between the wireless LAN router and the wireless LAN repeater is equivalent to an outdoor communication path, communication must be conducted using the 2.4GHz band, the 5GHz W56 band, or the 6GHz band VLP. However, traditional wireless LAN routers and repeaters can technically communicate even in the 5GHz W52 band, W53 band, and 6GHz band LPI. Therefore, connecting the wireless LAN router and repeater via the outdoor communication path using the 5GHz W52 band, W53 band, or 6GHz band LPI is considered to violate regulations and have adverse effects on radar, etc.

[0026] Additionally, during startup, if the W56, which allows outdoor use and has a large communication capacity, communicates between the router and repeater, and the wireless LAN router detects radar waves, it may switch the wireless frequency band to the W52 or W53, which are prohibited from outdoor use, depending on the wireless LAN router's control algorithm.

[0027] Furthermore, even in a wireless LAN repeater that has the function of switching communication with the host from the W56 band to the 2.4GHz band when radar waves are detected, the information of radar wave detection cannot be transmitted to the wireless LAN router. Therefore, even if the wireless LAN router cannot detect radar waves, there is a possibility that the communication between the wireless LAN router and the wireless LAN repeater can remain on the W56 band.

[0028] In the invention described in Patent Document 1, a detector for determining whether the device is indoors or outdoors is mounted on a display terminal that forms a wireless communication system with the base device. However, the detector described in Patent Document 1 detects whether the device is indoors or outdoors, such as... Figure 6 The description states that the wireless LAN repeater is indoors, while the wireless LAN router and the wireless LAN repeater are outdoors, thus classifying it as indoors.

[0029] Furthermore, in the wireless communication device (wireless LAN repeater) described in Patent Document 2, the use of the W52 and W53 frequency bands is permitted only when the first communication unit connected to the router is using the W52 or W53 frequency band, i.e., when it is determined that the communication path between the router and the repeater is an indoor communication path. However, as... Figure 6 In the case where the described wireless LAN repeater and host are located indoors, and the communication path between the wireless LAN router and the wireless LAN repeater is outdoors, even if the wireless LAN router and the wireless LAN repeater are using the 2.4GHz or W56 band, the wireless LAN repeater and the host can use the W52 or W53 band. Therefore, the control algorithm of the invention described in Patent Document 2 is not suitable. Figure 6 The usage described in the document.

[0030] Furthermore, 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 of communication with the host as an essential function in the repeater for the wireless LAN, and there is no description of the case of detecting radar waves, the present invention cannot be a solution to the technical problem to be solved by the present invention.

[0031] Furthermore, in the invention described in Patent Document 4, when the location information of the device is obtained in a location where outdoor use is highly probable, a wireless communication method using a frequency band permitted for outdoor use is selected from the first and second frequency bands. However, in the case of the invention described in Patent Document 4, only the device itself detects the location information; therefore, as... Figure 6 In cases where the described wireless LAN repeater and host are located indoors, and the wireless LAN router and wireless LAN repeater are located outdoors, there is a possibility of misjudging the available wireless communication methods.

[0032] Furthermore, there is no record of detecting radar waves in Patent Document 4.

[0033] The main objective of this invention is to provide a wireless LAN repeater, a wireless LAN router, and a wireless LAN system with a wireless LAN channel switching method. The wireless LAN repeater, which is configured in a side room or the like and connected to a wireless LAN router configured in a main room or the like via an outdoor communication path, can use radio frequency bands that are permitted for outdoor use as stipulated by law, and can preferentially use frequency bands with larger communication capacity.

[0034] A further objective of this invention is to provide a wireless LAN repeater, a wireless LAN router, and a wireless LAN system with a wireless LAN channel switching method. In a wireless LAN router connected to the wireless LAN repeater via an outdoor communication path, when radar waves in the W56 band are detected and the wireless LAN router and wireless LAN repeater cannot connect on the existing channel, the invention enables reconnection via a frequency band with the largest possible communication capacity, while simultaneously allowing connection to the wireless LAN router via a frequency band with the largest communication capacity, and maximizing the speed of recovery to that frequency band. (1)

[0036] According to one aspect, a wireless LAN repeater is provided, which is used in a room mode for connecting to a wireless LAN router via an outdoor communication path and simultaneously connecting to a first host via an indoor communication path. This wireless repeater includes wireless communication circuits capable of communication in the 2.4 GHz band, wireless communication circuits capable of communication in the 5 GHz band, and wireless communication circuits capable of communication in the 6 GHz band. When the room mode is activated, it selects the most suitable communication environment from the connectable frequency bands of the 6 GHz band (Very Low Power), the 5 GHz band (W56), and the 2.4 GHz band and connects to the wireless LAN router. Simultaneously, for the first host, it connects to the 2.4 GHz band, the 5 GHz band, and / or the 6 GHz band according to the host's request.

[0037] It should be noted that when the connection between the wireless LAN repeater and the first host is on the 6GHz band, it can also be connected via the 6GHz band LPI (Low Power Indoor).

[0038] Furthermore, when connecting to both a wireless LAN router and a host simultaneously in the same frequency band (6GHz, 5GHz, or 2.4GHz), the same channel is used for connection in each band. Additionally, connecting in the 2.4GHz, 5GHz W56, and / or 6GHz bands refers to connecting using a frequency band selected from the group consisting of the 2.4GHz, 5GHz W56, and 6GHz bands, including individual bands and combinations thereof.

[0039] When a wireless LAN router is configured in the main house and a wireless LAN repeater is configured in a separate room, the use of the 5GHz W52, W53, or 6GHz LPI bands via an outdoor communication path by the wireless LAN repeater violates regulations. However, in one aspect of the wireless LAN repeater, communication between the wireless LAN router and the repeater uses only the 6GHz VLP, 5GHz W56, or 2.4GHz bands permitted for outdoor communication, without potentially affecting satellite communication systems, weather radar, or telecommunications services (fixed satellite, etc.), and therefore does not violate regulations.

[0040] Furthermore, in the case of a wireless LAN repeater, the most suitable communication environment is selected and connected from the 6GHz VLP band, the 5GHz W56 band, and the 2.4GHz band. Therefore, for example, in cases where the distance between the wireless LAN router and the wireless LAN repeater is far, compared to the 6GHz VLP band, which has a wider bandwidth but a maximum EIRP of 25mW and a smaller capacity, the 5GHz W56 band, which has a narrower bandwidth but a maximum EIRP of 1000mW (with TPC), offers greater communication capacity. By selecting the 5GHz W56 band, a communication environment with a larger communication capacity can be selected.

[0041] It should be noted that if the wireless LAN repeater has two or more wireless communication circuits that can communicate in the 5GHz band, the connection to the wireless LAN router can be set to the W56 band in the 5GHz band, and the connection to the first host can be set to W52 or W53. (2)

[0043] In the wireless LAN repeater of the second invention, the wireless communication circuit capable of communication in the 2.4 GHz band, the wireless communication circuit capable of communication in the 5 GHz band, and the wireless communication circuit capable of communication in the 6 GHz band can each be composed of a single circuit.

[0044] At this point, the circuit size of the wireless communication circuit can be suppressed.

[0045] It should be noted that in future practical applications such as WiFi 7, where multi-link operation (MLO) can be used simultaneously on multiple frequency bands during connection, in order to smoothly initiate MLO, it is preferable to limit the connection between the wireless LAN repeater and the host in the 5GHz band to W56. (3)

[0047] In the third invention, a wireless LAN repeater, when unable to connect to a wireless LAN router in the 6GHz band VLP, requests that the wireless LAN router be able to connect in the 6GHz band VLP. When the 6GHz band VLP is available, the repeater can again select the most suitable communication environment from the available frequency bands among the 6GHz band VLP, the 5GHz W56 band, and the 2.4GHz band and connect to the wireless LAN router.

[0048] The wireless LAN repeater of the present invention, if capable of using the 6GHz band for connection to an indoor host, connects via LPI (Limited Portability Point) on the 6GHz band, which has a large communication capacity. However, if the wireless LAN repeater has the function of setting LPI / VLP for each connected terminal, the wireless LAN repeater can also connect to a wireless LAN router via VLP on the 6GHz band.

[0049] In a wireless LAN repeater with this function, when the wireless LAN router does not allow connection via 6GHz band VLP, but instead allows connection via 5GHz W56 band or 2.4GHz band, the wireless LAN repeater sends a connection request for 6GHz band VLP to the wireless LAN router. If a connection via 6GHz band VLP is possible, the repeater selects the most suitable communication environment from the available frequency bands among 6GHz band VLP, 5GHz W56 band, and 2.4GHz band and connects to the wireless LAN router. When the communication environment of 6GHz band VLP is most suitable, the repeater switches to 6GHz band VLP, thereby increasing the communication capacity of both the wireless LAN router and the wireless LAN repeater.

[0050] It should be noted that even in wireless LAN repeaters that do not have the function of setting LPI / VLP for each connected terminal, such as when the host of the wireless LAN repeater does not have a host capable of communicating in the 6GHz band, the wireless LAN repeater may still send a 6GHz band VLP connection request to the wireless LAN router if the connection with the host does not require the use of 6GHz band LPI, or if it is desired to prioritize increasing the communication capacity between the wireless LAN repeater and the wireless LAN router over the communication capacity between the wireless LAN repeater and the host.

[0051] However, accepting connection requests from 6GHz band VLPs is not a standard function of wireless LAN routers, but a separate function. Therefore, in order for a wireless LAN router to accept and allow 6GHz band VLP connection requests, a wireless LAN router with a room mode is required. (4)

[0053] In the fourth invention, a wireless LAN repeater, when unable to connect to a wireless LAN router using the 5GHz W56 band, attempts to connect to another channel of the 5GHz W56 band. If a connection to another channel of the 5GHz W56 band is also unsuccessful, the most suitable communication environment can be selected from the connectable frequency bands of the 6GHz VLP and 2.4GHz bands, and the repeater can connect to the wireless LAN router.

[0054] When a wireless LAN repeater is connected to a wireless LAN router via a 5GHz W56 band channel, the wireless LAN router monitors radar waves. Upon detecting radar waves, it stops the connection on the 5GHz W56 band channel and forwards communication to the wireless LAN repeater to another channel capable of 6GHz band VLP, 5GHz W56 band, and / or 2.4GHz band.

[0055] At this point, the wireless LAN repeater first attempts to connect on another channel in the 5GHz W56 band. If a connection is established, it continues to connect on the other channel.

[0056] On the other hand, if a connection cannot be made on another channel in the 5GHz W56 band, the most suitable communication environment is selected from the available frequency bands in the 6GHz VLP and 2.4GHz bands, and the connection is made to a wireless LAN router.

[0057] The reason for prioritizing the connection on another channel in the 5GHz W56 band is to avoid increasing the processing load of the wireless LAN repeater when it restarts every time radar waves are detected. In addition, it avoids affecting the communication between the wireless LAN repeater and the first host due to changes in the connection with the first host. (5)

[0059] In the fifth invention, a wireless LAN repeater, when unable to connect to a wireless LAN router via the 5GHz W56 band, simultaneously connects to the router via the 6GHz VLP or 2.4GHz band while investigating the possibility of connection on another channel of the 5GHz W56 band. If a connection is possible on the other channel of the 5GHz W56 band, the most suitable communication environment can be selected again from the connectable frequency bands of the 6GHz VLP, 5GHz W56, and 2.4GHz bands, and then connected to the wireless LAN router.

[0060] In the wireless LAN repeater of the fourth invention, firstly, a connection is attempted on another channel in the 5GHz W56 band. If a connection is successful, then a connection is established on the other channel, thereby suppressing the increase in the processing load of the wireless LAN repeater and the impact on the communication between the wireless LAN repeater and the first host.

[0061] However, in order to establish a connection on another channel, it is necessary to confirm that there are no radar signals for at least one minute. Therefore, the connection between the wireless LAN router and the wireless LAN repeater must be interrupted for at least one minute.

[0062] In the wireless LAN repeater of the fifth invention, to avoid the one-minute communication interruption, firstly, the possibility of connecting to the wireless LAN router in the 6GHz band VLP or 2.4GHz band, and connecting in parallel on another channel in the 5GHz W56 band, is investigated. If a connection can be made on the other channel in the 5GHz W56 band, the most suitable communication environment is selected again from the connectable frequency bands of the 6GHz band VLP, the 5GHz W56 band, and the 2.4GHz band, and then connected to the wireless LAN router.

[0063] It should be noted that if a connection can be established on another channel of the 5GHz W56 band, the connection to the wireless LAN router can also be switched to another channel of the 5GHz W56 band. (6)

[0065] The wireless LAN repeater of the sixth invention, according to one aspect, determines at predetermined time intervals whether it can connect to a wireless LAN router via the 6GHz band VLP and the 5GHz W56 band. If either the 6GHz band VLP or the 5GHz W56 band changes from unconnectable to connectable, it can again select the most suitable communication environment from the connectable frequency bands of the 6GHz band VLP, the 5GHz W56 band, and the 2.4GHz band, and connect to the wireless LAN router.

[0066] Upon startup, even if the most suitable communication environment is selected and a connection is established from the available frequency bands among the 6GHz VLP, 5GHz W56, and 2.4GHz bands, after a specified period of time, either the 6GHz VLP or the 5GHz W56 band will change from unconnectable to connectable.

[0067] For example, in situations where mobile devices such as smartphones connected to a wireless LAN router via 6GHz LPI are out with the user, or in situations where radar waves are interrupted for a period of time.

[0068] Therefore, it is recommended to confirm whether a connection can be established with the wireless LAN router in the 6GHz VLP and 5GHz W56 bands. If either the 6GHz VLP or 5GHz W56 band changes from unconnectable to connectable, it is preferable to return when activating the room mode to select the most suitable communication environment and reconnect.

[0069] It should be noted that the specified time is, for example, 30 minutes. (7)

[0071] The wireless LAN repeater of the 7th invention may also have multiple SSIDs, with the SSID connected to the wireless LAN router corresponding to the 6GHz band VLP and the SSID of the first host corresponding to the 6GHz band LPI.

[0072] At this time, 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 achieve the avoidance of legal violations and the maximization of communication capacity to the first host. (8)

[0074] The wireless LAN router of the 8th invention is a room-mode wireless LAN router that can be used when connected to a wireless LAN repeater via an outdoor communication path and simultaneously connected to a second host via an indoor communication path. It includes a wireless communication circuit capable of communication in the 2.4 GHz band, a wireless communication circuit capable of communication in the 5 GHz band, a wireless communication circuit capable of communication in the 6 GHz band, and a network circuit capable of connecting to wired WAN and LAN. The wireless communication circuit capable of communication in the 6 GHz band is configured such that for each connected terminal of the wireless LAN repeater and the second host, communication can be selected from the 6 GHz band VLP and the 6 GHz band LPI.

[0075] However, if the router is used as a wireless LAN access point, a network circuit may not be necessary.

[0076] At this time, if the wireless LAN router is set to room mode, it can, for example, connect to the wireless LAN repeater connected via an outdoor communication path using the 6GHz band VLP, and connect to the second host connected via an indoor communication path using the 6GHz band LPI. Therefore, it will not violate the law and can provide the maximum communication capacity for the wireless LAN repeater and the second host.

[0077] It should be noted that when the wireless LAN repeater also has a room mode, it can receive notifications of connections via an outdoor communication path, but it is generally unknown whether the connection to the wireless LAN repeater is via an outdoor communication path. In this case, the MAC address of the connection terminal via an outdoor communication path can be entered when the wireless LAN router is started.

[0078] Furthermore, since a wireless communication circuit capable of communication in the 6GHz band can be used to communicate between the 6GHz band VLP and the 6GHz band LPI, the circuit size of the wireless LAN router can be reduced.

[0079] It should be noted that for wireless LAN routers, by having two or more wireless communication circuits capable of communicating in the 5GHz band, the connection to the wireless LAN repeater can be set to W56, and the connection to the second host can be set to W52 or W53. (9)

[0081] The wireless LAN router of the 9th invention can also have multiple SSIDs, the SSID connected to the wireless LAN repeater corresponds to the 6GHz band VLP, and the SSID connected to the second host corresponds to the 6GHz band LPI.

[0082] At this time, the repeater for the wireless LAN 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. This can reliably avoid violations of the law and maximize the communication capacity to the second host. (10)

[0084] The wireless LAN router of the 10th invention, compared to the wireless LAN router of the 8th invention, can identify the second host and the wireless LAN repeater by receiving identification information from the wireless LAN repeater.

[0085] In a wireless LAN router, a connection terminal can connect both a second host and a wireless LAN repeater. However, from the perspective of the wireless LAN router, it is sometimes impossible to identify which connection terminal is the second host and which connection terminal is the wireless LAN repeater.

[0086] According to the 10th invention, a wireless LAN repeater sends identification information indicating that it is a wireless LAN repeater corresponding to a room mode. By receiving the identification information, the wireless LAN router can identify which connection terminal is the wireless LAN repeater.

[0087] Therefore, even if the user does not pre-configure the settings for identifying the wireless LAN repeater (entering the MAC address, IP address, SSID, etc. of the wireless LAN repeater), it can identify which connected terminal is the second host capable of communicating with the indoor communication path, or which connected terminal is the wireless LAN repeater that needs to communicate with the outdoor communication path, and thus automatically select the appropriate communication method.

[0088] It should be noted that the wireless LAN repeater of any one of the inventions in the first to seventh inventions can send the identification information, and the wireless LAN router of any one of the inventions in the eighth to eleventh inventions can receive the identification information to identify the second host and the wireless LAN repeater. (11)

[0090] The 11th invention is a wireless LAN router in a room mode that can be used when connected to a wireless LAN repeater via an outdoor communication path and simultaneously connected to a second host via an indoor communication path. It includes a wireless communication circuit capable of communication in the 2.4 GHz band, a wireless communication circuit capable of communication in the 5 GHz band, a wireless communication circuit capable of communication in the 6 GHz band, and a network circuit capable of connecting to wired WAN and LAN. The wireless communication circuit capable of communication in the 6 GHz band is configured such that all connected terminals of the wireless LAN repeater and the second host can only communicate in one of the 6 GHz band VLP and the 6 GHz band LPI. When the wireless LAN repeater requests a connection in the 6 GHz band VLP and the wireless LAN router is not connected to the second host via the 6 GHz band LPI, the communication in the 6 GHz band is switched from LPI to VLP.

[0091] Wireless LAN routers typically communicate with a second host via the 6GHz band LPI. In this case, a wireless LAN router configured to communicate only with the wireless LAN repeater and all connected terminals of the second host via either the 6GHz band VLP or the 6GHz band LPI cannot connect to a wireless LAN repeater connected via an outdoor communication path via 6GHz.

[0092] However, for reasons such as the second host not having a wireless communication circuit capable of communication in the 6GHz band, if the wireless LAN router is not connected to the second host via 6GHz LPI, the communication capacity with the wireless LAN repeater can be increased by switching the wireless LAN router's 6GHz band communication from LPI to VLP.

[0093] In addition, in a wireless LAN router configured to communicate only with the wireless LAN repeater and all connected terminals of the second host in one of the 6GHz band VLP and 6GHz band LPI, if it is desired to prioritize increasing the communication capacity of the wireless LAN router and the wireless LAN repeater, communication in all 6GHz bands, including communication with the second host, can be set to VLP.

[0094] It should be noted that when the wireless LAN repeater also has a room mode, it can receive notifications of connections via an outdoor communication path, but it is generally unknown whether the connection to the wireless LAN repeater is via an outdoor communication path. In this case, the MAC address of the terminal via the outdoor communication path can be entered when the wireless LAN router is started. (12)

[0096] The wireless LAN system of the 12th invention comprises a wireless LAN router of the 8th to 11th inventions and a second host, a wireless LAN repeater of the 7th invention and a first host configured in a compartment. The wireless LAN router and the wireless LAN repeater are both set to compartment mode. While connected via an outdoor communication path, the wireless LAN router is connected to the second host via an indoor communication path, and the wireless LAN repeater is connected to the first host via an indoor communication path.

[0097] When a wireless LAN router or wireless LAN repeater has a compartment mode, setting the wireless LAN router or wireless LAN repeater to compartment mode does not affect the satellite communication system or weather radar, does not violate the law, and can form a communication system with the maximum communication capacity.

[0098] It should be noted that, as Figure 16As described, the main building and side buildings generally refer to the main building being equivalent to the main building and the smaller buildings being equivalent to side buildings in a residential building consisting of two or more independent buildings. However, in this specification, in two or more independent buildings, regardless of the size of the buildings, the building equipped with a wireless LAN router is the main building.

[0099] However, if both the wireless LAN router and the wireless LAN repeater have a room mode, the following effect can be obtained by setting both the wireless LAN router and the wireless LAN repeater to room mode.

[0100] 1) When the wireless LAN router and the wireless LAN repeater communicate in the 5GHz W56 band or the 2.4GHz band, the wireless LAN repeater sends a 6GHz band VLP connection request to the wireless LAN router. The wireless LAN router accepts the connection request and can establish a 6GHz band VLP connection when the wireless LAN router is capable of establishing an LPI / VLP connection for each terminal, or when there are no other terminals connected via 6GHz LPI.

[0101] 2) It can send identification information from the wireless LAN repeater to the wireless LAN router indicating that the wireless LAN repeater is connected via an outdoor communication path. The wireless LAN router does not allow the wireless LAN repeater to communicate in the 6GHz LPI, 5GHz W52, and W53 bands without permission via the outdoor communication path, thus more reliably eliminating legal violations.

[0102] It should be noted that 1) and 2) above are not standard functions of a wireless LAN system, but rather standalone functions. (13)

[0104] The wireless LAN system of the 13th invention is the same as that of the wireless LAN router and the wireless LAN repeater in the 12th invention. The wireless LAN router and the second host have multiple SSIDs respectively. The SSID of the connection between the wireless LAN router and the second host is the same as the SSID of the connection between the wireless LAN repeater and the first host. The SSID of the connection between the wireless LAN router and the wireless LAN repeater may also be different from the same SSID.

[0105] At this point, since the first and second hosts are configured with the same SSID, the wireless LAN connection can continue even if the host used in the main room (e.g., a smartphone) is moved to a side room. Furthermore, since the SSIDs of the connection between the wireless LAN router and the wireless LAN repeater are different from those of the connection between the wireless LAN router / repeater and the host, setting the connection between the wireless LAN router and the wireless LAN repeater to the most suitable communication for outdoor communication (e.g., VLP) allows the connection between the wireless LAN router / repeater and the host to be matched with the most suitable communication for indoor communication (e.g., LPI). (14)

[0107] The wireless LAN system of the 14th invention is in the same wireless LAN system as the 12th invention. The wireless communication circuit of the 5GHz band of the wireless LAN repeater has a radar wave detection circuit. When the wireless LAN repeater detects radar waves in the 5GHz W56 band, the wireless LAN repeater transmits the radar wave detection information to the wireless LAN router, and the wireless LAN router determines that radar waves have been detected.

[0108] In the wireless LAN system of the 12th invention, sometimes the wireless LAN router is placed in a location far from the outer wall, such as in the center of the main room, while the wireless LAN repeater is 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 detect radar waves.

[0109] In the wireless LAN system of the 14th invention, when the wireless LAN repeater detects radar waves in the 5GHz W56 band, the wireless LAN repeater transmits the radar wave detection information to the wireless LAN router, thereby enabling the wireless LAN router to reliably suspend the use of the channel when radar waves arrive.

[0110] It should be noted that this radar wave detection information transmission function is not a standard function of the wireless LAN system, but a separate function. (15)

[0112] The wireless LAN system of the 15th invention comprises a wireless LAN router and a second wireless LAN repeater configured in the main room, a first wireless LAN repeater configured in the side room from any one of the inventions of the 7th invention, and a first host. The second wireless LAN repeater and the wireless LAN router are connected through an indoor communication path. The first wireless LAN repeater is set to side room mode and is connected to the second wireless LAN repeater through an outdoor communication path while also being connected to the first host through an indoor communication path.

[0113] At this point, by having a wireless LAN router and a second wireless LAN repeater in the main room, it is possible to communicate with a larger range and more hosts configured in the same main room. (16)

[0115] The wireless LAN system of the 16th invention comprises a wireless LAN router of any one of the 8th to 11th inventions configured in the main room, a first wireless LAN repeater of any one of the 7th inventions configured in the side room, a third wireless LAN repeater, and a first host. The wireless LAN router and the first wireless LAN repeater are configured in side room mode and connected via an outdoor communication path. The third wireless LAN repeater is connected to the first wireless LAN repeater via an indoor communication path and is also connected to the first host via an indoor communication path.

[0116] At this point, by equipping the compartment with a first wireless LAN repeater and a third wireless LAN repeater, it is possible to communicate with a larger range and more hosts configured in the same compartment. (17)

[0118] The wireless LAN system of the 17th invention comprises a wireless LAN router of the 8th to 11th inventions configured in the main room, a fourth wireless LAN repeater of any one of the inventions of the 7th invention configured in one side of the 1st room, a first wireless LAN repeater of any one of the inventions of the 7th invention configured in one side of the 2nd room, and a first host. The wireless LAN router and the fourth wireless LAN repeater are configured in room mode and connected via an outdoor communication path. The first wireless LAN repeater is configured in room mode and connected to the fourth wireless LAN repeater via an outdoor communication path while simultaneously connecting to the first host via an indoor communication path.

[0119] At this point, by configuring a wireless LAN router of any one of the inventions from the 8th to the 11th inventions in the main room, configuring a first wireless LAN repeater of any one of the inventions from the 1st to the 7th inventions in the first side room, and further configuring a fourth wireless LAN repeater of any one of the inventions from the 1st to the 7th inventions in the second side room, it is possible to connect the hosts of three independent buildings to a single router.

[0155] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the following description, the same parts are labeled with the same reference numerals. Furthermore, where the same reference numerals are used, their names and functions are also the same. Therefore, detailed descriptions of them will not be repeated.

[0156] [Wireless LAN System 1000]

[0157] Figure 1 This is a schematic diagram of a wireless LAN system 1000, consisting of a wireless LAN router 200, a wireless LAN repeater 100, and hosts 300 and 300a. Figure 1 In this embodiment, a wireless LAN router 200 is configured in the first building (hereinafter referred to as the main building 400), and a wireless LAN repeater 100 is configured in the second building (hereinafter referred to as the side building 500). In this embodiment, the main building 400 is equipped with an ONU (Optical Network Unit) for optical links, providing an environment capable of wired internet connectivity, while the side building 500 lacks a wired internet environment. Furthermore, the first host 300 located in the side building 500 cannot directly communicate with the wireless LAN router 200 in the main building 400, or even if a connection is possible, the signal strength is weak, the connection is unstable, and sufficient communication speed cannot be obtained. It should be noted that hosts 300 and 300a are, for example, personal computers, printers, smartphones, etc., equipped with wireless LAN.

[0158] The wireless LAN router 200 and the wireless LAN repeater 100 are configured in different buildings and therefore communicate via the outdoor communication path 600. The wireless LAN router 200 and the second host 330a, as well as the wireless LAN repeater 100 and the first host 300, are configured inside the same building and therefore communicate via the indoor communication path 700.

[0159] When using the 6GHz band for wireless LAN, indoors, the maximum equivalent isotropic radiated power (EIRP) of 200mW LPI and the maximum EIRP of 25mW VLP can be used, but outdoors only the maximum EIRP of 25mW VLP can be used.

[0160] On the other hand, in the 5GHz band, the W56 band can only be used outdoors, and there is a limitation that it must be moved to other channels when radar waves are detected.

[0161] The wireless LAN repeater 100 and the wireless LAN router 200 constituting this wireless LAN system 1000 reliably comply with the restrictions based on the aforementioned laws and regulations, and strive to maximize the communication capacity (speed) between the wireless LAN router 200 and the wireless LAN repeater 100, and between the wireless LAN repeater 100 and the first host 300.

[0162] [Wireless LAN Repeater 100 of the First Embodiment]

[0163] Figure 2 This is a schematic block diagram of the wireless LAN repeater 100 according to the first embodiment.

[0164] like Figure 2 As shown, the wireless LAN repeater 100 includes a 2.4GHz band wireless communication circuit 10, a 5GHz band wireless communication circuit 20, a 6GHz band wireless communication circuit 30, a control circuit 40, and a data buffer 50. Furthermore, the 2.4GHz band wireless communication circuit 10, the 5GHz band wireless communication circuit 20, and the 6GHz band wireless communication circuit 30 each include antennas 11, 21, and 31, respectively. The 2.4GHz and 5GHz bands 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 20 includes a radar wave detection circuit 22.

[0165] The radar wave detection circuit 22 is used for the DFS function, which monitors the radar waves in the 5GHz W53 and W56 frequency bands when the wireless LAN repeater 100 is communicating with the first host 300, and when the radar waves are detected, it switches to other channels or other frequency bands.

[0166] 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 transmitted radio waves of the wireless LAN repeater 100 are leaking outdoors. Therefore, for example, if the wireless LAN repeater 100 is connected to the wireless LAN router 200 via the 6GHz band VLP, and radar radio waves are detected in the 5GHz W56 band, the wireless LAN repeater 100 connecting to the first host 300 via the 5GHz W56 band may violate the law. When the radar radio wave detection circuit 22 of the 5GHz band wireless communication circuit 20 of the present invention detects radar radio waves, the wireless LAN repeater 100, during communication with the host 300, avoids communicating on the channel where radar radio waves are detected during the non-occupancy period, thus preventing the possibility of violating the law. It should be noted that the non-occupancy period (NOP) refers to the period during which the channel cannot be used when radar radio waves are detected, for example, 30 minutes.

[0167] With only one wireless communication circuit, only one channel can communicate in the 2.4GHz, 5GHz, and 6GHz bands respectively. Therefore, for example, if the communication (hereinafter also referred to as backhaul) between the wireless LAN router 200 and the wireless LAN repeater 100 takes place on a single channel in the 2.4GHz band, the communication between the wireless LAN router 200 and the host 300 can take place on the same channel as the backhaul in the 2.4GHz band, any channel in the 5GHz band, or any channel in the 6GHz band, but communication cannot take place on a channel different 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, simplifying the circuitry of the wireless LAN repeater 100. However, by having two wireless communication circuits in the 5GHz band, the backhaul can be set to W56, and the connection to the host can be set to W52 or W53.

[0168] While controlling each wireless communication circuit based on the flowchart described later, the control circuit 40 temporarily stores the information of the received data packets in the data buffer 50, reassembles them, and then sends them to the designated destination.

[0169] (Flowchart of the first embodiment)

[0170] Figure 3 , Figure 4 , Figure 5 This is a schematic flowchart illustrating the operation of the wireless LAN repeater 100 in the first embodiment when it is started. Figure 3This is a flowchart illustrating how the wireless LAN repeater 100 can select LPI and VLP for communication with each terminal (wireless LAN router 200 and first host 300) in the 6GHz band. Additionally, Figure 4 , Figure 5 This is a flowchart illustrating a scenario where a wireless LAN repeater 100 cannot select LPI and VLP for communication on a per-terminal basis in the 6GHz band. Figure 4 This is a flowchart illustrating the scenario where connection to the wireless LAN router 200 takes priority (connection to the wireless LAN router 200 via VLP, without connecting to the first host 300 via LPI). Figure 5 This is a flowchart illustrating the scenario where connection to the first host 300 is prioritized (connection to the first host 300 via LPI, without connecting to the wireless LAN router 200 via 6GHz).

[0171] in addition, Figure 6 This is a flowchart illustrating the process of reselecting the most suitable communication environment when the wireless LAN repeater 100 is connected to the wireless LAN router 200 via the 6GHz band VLP and can also connect via the 5GHz W56 band, or when it can connect via the 6GHz band VLP after connecting via the 5GHz W56 band.

[0172] It should be noted that, as a method of selecting LPI and VLP for communication for each terminal, LPI and VLP can also be selected each time communication with the terminal begins. For example, if the wireless LAN repeater 100 has multiple SSIDs (Service Set Identifier), the terminal communicating via LPI and the terminal connecting via VLP can belong to different SSIDs.

[0173] The following diagrams illustrate the operation of the wireless LAN repeater 100 during startup.

[0174] ( Figure 3 (Explanation of the flowchart)

[0175] Figure 3 This is a flowchart illustrating the scenario where the wireless LAN repeater 100 can select LPI and VLP for communication for each terminal (wireless LAN router 200 and first host 300) in the 6GHz band.

[0176] The wireless LAN repeater 100 of the first embodiment first checks whether it can detect the SSID of the 6GHz band from the wireless LAN router 200 when it starts up (step S1).

[0177] If the SSID of the 6GHz band is detected, confirm whether it is possible to connect to the wireless LAN router 200 via the 6GHz band VLP (step S2).

[0178] If a connection can be made via the 6GHz band VLP, further confirm whether a connection can also be made via the 5GHz W56 band (step S3).

[0179] If both the 6GHz VLP and 5GHz W56 bands can connect to the wireless LAN router 200, select the most suitable communication environment from the 6GHz VLP and 5GHz W56 bands and connect it to the wireless LAN router 200 (step S5). It should be noted that the selection of the most suitable communication environment is based on factors such as communication capacity and error rate.

[0180] In step S3, if a connection cannot be established via the 5GHz W56 band, confirm whether the connection with the wireless LAN router 200 is lost on the 2.4GHz band (step S4).

[0181] If both the 6GHz VLP and 2.4GHz bands can be connected to the wireless LAN router 200, select the most suitable communication environment between the 6GHz VLP and 2.4GHz bands and connect it to the wireless LAN router 200 (step S6).

[0182] In step S4, if a connection cannot be made via the 2.4GHz band, a connection is made via the 6GHz band VLP to the wireless LAN router 200 (step S7).

[0183] After establishing a connection with the wireless LAN router 200, the system sends the SSIDs for the 6GHz band LPI, 5GHz band, and 2.4GHz band to the first host 300, and connects to the first host 300 upon request. It should be noted that within the frequency bands used for connecting 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.

[0184] It should be noted that when comparing the communication environment of the 6GHz band VLP with the 5GHz W56 band or the 2.4GHz band, the 6GHz band VLP, with its wider bandwidth, should have the best communication environment. However, the 6GHz band VLP has a lower EIRP. Depending on the distance between the wireless LAN router 200 and the wireless LAN repeater 100, and whether there are any obstacles in between, the 5GHz W56 band or the 2.4GHz band may have a better communication environment.

[0185] In step S2, if a connection cannot be established via the 6GHz band VLP, it is confirmed whether the wireless LAN repeater 100 can connect to the wireless LAN router 200 via the 5GHz W56 band (step S9).

[0186] If a connection is possible via the 5GHz W56 band, connect to the wireless LAN router 200 via the 5GHz W56 band (step S11).

[0187] In step S9, if a connection cannot be established via the 5GHz W56 band, it is confirmed whether a connection can be established via the 2.4GHz band (step S10).

[0188] If a connection is possible via the 2.4GHz band, connect to the wireless LAN router 200 via the 2.4GHz band (step S12).

[0189] In step S10, if a connection cannot be established even via the 2.4GHz band, the process returns to step S1. At this point, a delay time until restarting or a maximum number of repetitions during restart can also be set.

[0190] After completing the connection with the wireless LAN router 200, it sends the SSIDs of the 6GHz band LPI, 5GHz band and 2.4GHz band to the first host 300, and connects to the first host 300 according to the request of the first host 300.

[0191] After connecting to the first host 300, the wireless LAN repeater 100 can request the wireless LAN router 200 to change from the 6GHz band LPI to the 6GHz band VLP (or add the 6GHz band VLP) (step S14).

[0192] Then, if a connection can be established via the 6GHz band VLP, return to step S3 and select the most suitable communication environment among the 6GHz band VLP, the 5GHz W56 band, and the 2.4GHz band to reconnect with the wireless LAN router 200 (step S15).

[0193] This function is useful in situations where the wireless LAN router 200 can connect via the 6GHz band VLP but is not sending the 6GHz band VLP SSID. However, since this function is not a standard feature of wireless LAN, the wireless LAN router 200 also needs to have a room mode (a separate function). Regarding this function, based on... Figure 10 To reiterate.

[0194] In step S1, if the SSID of the 6GHz band from the wireless LAN router 200 cannot be detected, the connection of the 5GHz W56 band is confirmed (step S16). If a connection can be established via the 5GHz W56 band, then a connection is established via the 5GHz W56 band (step S18). If a connection cannot be established via the 5GHz W56 band, the connection of the 2.4GHz band is confirmed (step S17). If a connection can be established via the 2.4GHz band, then a connection is established via the 2.4GHz band (step S19).

[0195] If a connection cannot be established via the 2.4GHz band in step S17, the process returns to step S1. At this point, a delay time until restarting or a maximum number of repetitions during restart can also be set.

[0196] After completing the connection with the wireless LAN router 200, it sends the SSIDs of the 6GHz band LPI, 5GHz band and 2.4GHz band to the first host 300, and connects to the first host 300 according to the request of the first host 300.

[0197] ( Figure 4 (Explanation of the flowchart)

[0198] Figure 4 This is a flowchart illustrating the scenario where, in 6GHz band communication, the repeater 100 for wireless LAN cannot select LPI or VLP for communication with each terminal (wireless LAN router 200 and first host 300), prioritizing the connection to the wireless LAN router 200 (connecting to the wireless LAN router 200 via VLP, but not connecting to the first host 300 via LPI). It should be noted that... Figure 4 In, with Figure 3 Steps with the same number represent the same Figure 3 The same action.

[0199] exist Figure 4 In the flowchart, after determining the connection method with the wireless LAN router 200 in steps S3 to S7, it is confirmed whether to connect to the wireless LAN router 200 via 6GHz VLP (step S8a). If the connection is made to the wireless LAN router 200 via 6GHz VLP, the connection to the first host 300 is not made via 6GHz LPI (step S8c). If the connection is made to the wireless LAN router 200 without using 6GHz band VLP, the connection to the first host 300 is made via 6GHz LPI (step S8b).

[0200] In step S8a, the wireless LAN repeater 100 is connected to the wireless LAN router 200 via a 6GHz VLP, meaning that this is the most suitable connection environment for the wireless LAN repeater 100 and the wireless LAN router 200. Therefore, even if the communication capacity between the wireless LAN repeater 100 and the first host 300 is reduced by setting the connection between the wireless LAN repeater 100 and the first host 300 to the 6GHz band VLP, it is still considered more preferable overall, especially in cases such as downloading large amounts of data from the Internet.

[0201] ( Figure 5 (Explanation of the flowchart)

[0202] Figure 5 This is a flowchart illustrating the scenario where, in communication using the wireless LAN repeater 100 in the 6GHz band, it is not possible to select LPI or VLP for communication with each terminal (wireless LAN router 200 and the first host 300). The flowchart prioritizes the connection to the first host 300 (connecting to the first host 300 via LPI, but not via the 6GHz band to the wireless LAN router 200). It should be noted that... Figure 5 In, with Figure 3 Steps with the same number represent the same Figure 3 The same action.

[0203] In cases where the first host 300 exchanges large amounts of data with each other via a wireless LAN using a repeater 100, etc. Figure 4 Compared to the flowchart, the preferred method is... Figure 5 The flowchart shows the priority of connection with the first host 300.

[0204] exist Figure 5 In the flowchart, after determining the connection method with the wireless LAN router 200 in steps S3 to S7, it is confirmed whether there is a connection request from the first host 300 to the 6GHz band LPI (step S7a).

[0205] If a connection request exists for the 6GHz band LPI, confirm whether to connect to the wireless LAN router 200 via the 6GHz band VLP (step S7b).

[0206] When connecting to the wireless LAN router 200 via the 6GHz band VLP, confirm the connection of the 5GHz W56 band (step S7c). If the connection can be made via the 5GHz W56 band, switch to connect to the 5GHz W56 band (step S7d). If the connection cannot be made via the 5GHz W56 band, switch to connect to the 2.4GHz band (step S7e).

[0207] Then, according to the request of the first host 300, the first host 300 is connected via any one of the 6GHz band LPI, the 5GHz W56 band, or the 2.4GHz band (step S8d).

[0208] On the other hand, in step S7a, if there is no connection request from the first host 300 via the 6GHz band LPI, the connection is made with the first host 300 via either the 5GHz W56 band or the 2.4GHz band according to the request of the first host 300 (step S8e).

[0209] ( Figure 6 (Explanation of the flowchart)

[0210] Figure 6 This is a flowchart illustrating the process of reselecting the most suitable communication environment when the wireless LAN repeater 100 connects to the wireless LAN router 200 via the 6GHz band VLP and is able to connect in the 5GHz W56 band, or when it connects in the 5GHz W56 band and is able to connect in the 6GHz band VLP.

[0211] exist Figure 6 In the case where the wireless LAN repeater 100 is not connected to the wireless LAN router 200 via the 6GHz band VLP (step S31), it is confirmed whether a connection can be established via the 6GHz band VLP (step S32). If a connection is established, then according to... Figures 3 to 5 The flowchart shows the process of restarting the wireless LAN repeater 100 from step S1 (step S35).

[0212] In step S32, if a connection cannot be established via the 6GHz band VLP and also fails to establish a connection via the 5GHz W56 band (e.g., a connection via 2.4GHz, etc.) (step S33), it is confirmed whether a connection can be established via the 5GHz W56 band (step S34). If a connection can be established, the wireless LAN repeater 100 is restarted (step S35).

[0213] In other cases, the wireless LAN continues its current state using repeater 100.

[0214] It should be noted that if this action of reselecting the most suitable communication environment is performed frequently, it will cause confusion in the connection between the wireless LAN repeater 100 and the wireless LAN router 200, as well as the connection between the wireless LAN repeater 100 and the first host 300. Therefore, it is preferable to stay at a specified time interval, such as once every 30 minutes.

[0215] [Wireless LAN Router 200 of the Second Embodiment]

[0216] Figure 7 This is a schematic block diagram of a wireless LAN router 200 according to the second embodiment.

[0217] like Figure 7 As shown, the wireless LAN router 200 includes a 2.4GHz wireless communication circuit 10a, a 5GHz wireless communication circuit 20a, a 6GHz wireless communication circuit 30a, a control circuit 40a, a data buffer 50a, and a network circuit 60. Furthermore, the 2.4GHz wireless communication circuit 10a, the 5GHz wireless communication circuit 20a, and the 6GHz wireless communication circuit 30a each have antennas 11a, 21a, and 31a, respectively. The 2.4GHz and 5GHz bands can also share an antenna by inserting an antenna switch (not shown) between the antenna and the wireless communication circuit. The 5GHz wireless communication circuit 20a includes a radar wave detection circuit 22a.

[0218] It should be noted that the wireless LAN router 200 in the second embodiment is the host of the wireless LAN, and also includes wireless LAN access points that do not have router functions. However, when the wireless LAN router 200 is a wireless LAN access point, the network circuit 60 may not be required.

[0219] The radar wave detection circuit 22a is used for the DFS function, which monitors radar waves in the 5GHz W53 and W56 frequency bands when the wireless LAN router 200, the wireless LAN repeater 100, and the second host 300a are communicating. If radar waves are detected, the radar waves are transferred to other channels or other frequency bands.

[0220] Furthermore, the wireless LAN router 200 has 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 other optical link.

[0221] (Flowchart of the second embodiment)

[0222] Figure 8 and Figure 9 These are flowcharts showing the startup process of router 200 in the wireless LAN mode of the private room. Figure 8 This is a flowchart illustrating a wireless LAN router 200 that has the ability to configure LPI / VLP for each connected terminal. Figure 9 This is a flowchart illustrating a situation where a wireless LAN router 200 cannot configure LPI / VLP for each connected terminal.

[0223] The following diagrams illustrate the actions of the wireless LAN router 200 during startup.

[0224] ( Figure 8 (Explanation of the flowchart)

[0225] During startup of the wireless LAN router 200 in room mode, the MAC address of the wireless LAN repeater 100 located in room 500 and connected via outdoor communication path 600 is first specified (step S41). However, if the wireless LAN repeater 100 is also set to room mode, identification information can also be received from the wireless LAN repeater 100.

[0226] Next, the wireless LAN router 200 outputs the SSIDs for the 6GHz band LPI, 6GHz band VLP, 5GHz band W56, and 2.4GHz band (step S42).

[0227] Next, if either the wireless LAN repeater 100 or the second host 300a makes a connection request via the 6GHz band LPI and the terminal making the connection request is not connected to the wireless LAN repeater 100 of the room 500 via the outdoor connection path, the connection via the 6GHz band LPI is allowed (steps S43 to S45).

[0228] Next, if there is a connection request from any connection terminal via the 6GHz band VLP (step S46), the connection via the 6GHz band LPI is allowed (step S47).

[0229] Furthermore, if there is a connection request from any connection terminal via the 5GHz W56 band (step S48), the connection via the 5GHz W56 band is allowed (step S49); if there is a connection request from any connection terminal via the 2.4GHz band (step S50), the connection via the 2.4GHz band is allowed (step S51).

[0230] It should be noted that the wireless LAN router 200 connects to the second host 300a in the 5GHz band using the W56 frequency band so that, in future practical applications such as WiFi 7, multiple link operation (MLO) can be used simultaneously to connect the wireless LAN router 200 and the wireless LAN repeater 100, allowing both the 5GHz and 6GHz bands to be used for connection. Therefore, without using MLO, when the connection between the wireless LAN router 200 and the wireless LAN repeater 100 does not use the 5GHz W56 frequency band, or when the wireless LAN repeater 100 has two wireless communication circuits in the 5GHz band and can communicate with both W56 and W52 / W53, the communication in the 5GHz band is not limited to the W56 frequency band.

[0231] Furthermore, even 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, it can connect to the second host 300a through all frequency bands by starting the wireless LAN router 200 in normal mode.

[0232] ( Figure 9 (Explanation of the flowchart)

[0233] Figure 9 This is a flowchart illustrating the scenario where the wireless LAN router 200 cannot configure LPI / VLP for each connected terminal. Therefore, it can only connect to the wireless LAN repeater 100 via the 6GHz band VLP when the wireless LAN router 200 is not connected to the second host 300a via the 6GHz band LPI. It should be noted that... Figure 9 In, with Figure 8 Steps with the same number represent the same Figure 8 The same action.

[0234] At this point, since the SSID initially sent does not include the SSID of the 6GHz band VLP (step S42a), the SSID of the 6GHz band VLP is retransmitted if it is known that the 6GHz band VLP is not used (step S43 is no, or step S44 is yes) (step S42b). If there is a connection request from any connected terminal via the 6GHz band VLP (step S46), the connection via the 6GHz band VLP is allowed (step S47).

[0235] Regarding steps S48 to S51, and Figure 8 same.

[0236] [Wireless LAN System 1000]

[0237] The configuration of the wireless LAN system 1000 is as follows: Figure 1 As shown.

[0238] Since the wireless LAN router 200 and the wireless LAN repeater 100 are configured in different buildings, they communicate via the outdoor communication path 600. Since the wireless LAN router 200 and the second host 300a and the wireless LAN repeater 100 and the first host 300 are configured inside the same building, they communicate via the indoor communication path 700.

[0239] Even when only the wireless LAN repeater 100 or only the wireless LAN router 200 is set to room mode, the present invention can achieve the objective of constructing a communication system that does not violate the law and maximizes the communication capacity. However, when both the wireless LAN router 200 and the wireless LAN repeater 100 are set to room mode, the effect can be further improved.

[0240] Here, the operation is based on the condition that both the wireless LAN router 200 and the wireless LAN repeater 100 are set to room mode. Figure 10 This section explains the scenario where the wireless LAN repeater 100 sends a handover request from the 6GHz band LPI to the 6GHz band VLP to the wireless LAN router 200. Additionally, based on... Figure 11 as well as Figure 12 This section explains the communication process between the wireless LAN repeater 100 and the wireless LAN router 200 during radar wave detection.

[0241] (Switching requests and responses from 6GHz band LPI to 6GHz band VLP)

[0242] Figure 10 This is a flowchart illustrating the actions taken when a wireless LAN repeater 100 sends a handover request from a 6GHz band LPI to a 6GHz band VLP to a wireless LAN router 200.

[0243] When the wireless LAN router 200 is connected to the wireless LAN repeater 100 via the 5GHz W56 band or the 2.4GHz band (step S51), and the wireless LAN router 200 receives a change request from the wireless LAN repeater 100 to the 6GHz band VLP (step S52), the wireless LAN router 200 checks whether the 6GHz band can be changed to VLP (step S53). Normally, 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.

[0244] If the 6GHz band can be changed to VLP, change the 6GHz band to VLP (step S54) and reply OK to the wireless LAN repeater 100 (step S55). If it cannot be changed, reply NG to the wireless LAN repeater 100 (step S56).

[0245] It should be noted that this flowchart is for the case where the wireless LAN router 200 cannot configure the 6GHz band VLP / LPI for each terminal. When the wireless LAN router 200 can configure the 6GHz band VLP / LPI for each terminal, step S53 is always "Yes". The wireless LAN router 200 adds the 6GHz band VLP (sends the SSID containing the 6GHz band VLP) and only replies OK to the wireless LAN repeater 100.

[0246] By having this function, the wireless LAN system 1000 can reliably connect via the 6GHz band VLP when the wireless LAN router 200 and the wireless LAN repeater 100 can connect via the 6GHz band VLP, even when the second host 300a does not communicate via the 6GHz band LPI, thereby increasing the communication capacity between the wireless LAN router 200 and the wireless LAN repeater 100.

[0247] (Coordination actions during radar wave detection)

[0248] Regarding communication between the wireless LAN router 200 and the wireless LAN repeater 100, if the radar wave detection circuit 22a of the wireless LAN router 200 detects radar waves, the wireless LAN router 200, during non-occupancy periods, avoids communicating on the radar wave channel, thus preventing potential violations of regulations. However, there are also cases where the wireless LAN router 200 is placed away from the outer wall of the main building 400, and the wireless LAN repeater 100 is placed near the outer wall of the side room 500. In these cases, the radar wave detection circuit 22a of the wireless LAN router 200 cannot detect radar waves, while the radar wave detection circuit 22a of the wireless LAN repeater 100 may detect radar waves.

[0249] 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 room mode, in order to ensure that the DFS function does not violate the law under such circumstances, Figure 11 or Figure 12 The actions shown.

[0250] exist Figure 11 In the case where the radar wave detection circuit 22 of the wireless LAN repeater 100 detects radar waves (step S61), the wireless LAN repeater 100 transmits the radar wave detection information to the wireless LAN router 200 (step S62).

[0251] When the wireless LAN router 200 receives radar wave detection information from the wireless LAN repeater 100 or when its own radar wave detection circuit 22a detects a radar wave (step S63), it stops communication on the channel of the 5GHz W56 band in use (step S64) and confirms the connection on another channel of the 5GHz W56 band (step S65). Specifically, it searches for a channel where no radar waves have been detected for more than one minute and where the radar waves of other wireless LANs with different SSIDs are low.

[0252] If a connection can be made on another channel in the 5GHz W56 band (step S66), the wireless LAN repeater 100 is connected on that channel (step S67). If this is not possible, in order to find the most suitable communication environment for the wireless LAN router 200 and the wireless LAN repeater 100, the wireless LAN repeater 100 and the wireless LAN router 200 are restarted from steps S1 and S42 to S42a respectively (step S68).

[0253] However, during the restart of the wireless LAN repeater 100, the "Do you connect via the 5GHz W56 band?" option in steps S3 and S9 is "No". Additionally, during the restart of the wireless LAN router 200, the SSID of the 5GHz W56 band is not output in steps S42, S42a, and S42b.

[0254] exist Figure 12 In step S64, after communication on the 5GHz W56 band channel used in the process is stopped by radar detection, the wireless LAN router 200 first connects to the wireless LAN repeater 100 at 6GHz (VLP) or 2.4GHz (step S71). Then, the wireless LAN router 200 maintains the communication from step S71 and investigates the possibility of a connection on another channel in the 5GHz W56 band (step S72). Specifically, it searches for another channel where no radar waves have been detected for more than one minute and where the radio waves of other wireless LANs with different SSIDs are low.

[0255] If a connection can be established on another channel in the 5GHz W56 band (step S73), the wireless LAN router 200 switches the connection with the wireless LAN repeater 100 to another channel in the 5GHz W56 band (step S74). If this is not possible, the connection with the wireless LAN repeater 100 continues in the 6GHz or 2.4GHz band.

[0256] It should be noted that in step S74, in Figure 12 An example of switching to another channel in the W56 band is shown, but it is not limited thereto. In order to find the most suitable communication environment for the wireless LAN router 200 and the wireless LAN repeater 100, the wireless LAN repeater 100 and the wireless LAN router 200 can be restarted from steps S1 and S42 to S42a, respectively.

[0257] exist Figure 11 In this method, after ceasing communication on the 5GHz W56 band, it is necessary to confirm that there are no radar radio waves on another channel for at least one minute, therefore communication must be stopped for at least one minute. On the other hand, in Figure 12 The method requires a temporary connection to the wireless LAN repeater 100 at 6GHz or 2.4GHz, but it is advantageous in that it can avoid at least one minute of communication interruption.

[0258] (Advantages of the wireless frequency band switching method in the room mode)

[0259] When the wireless LAN router 200 configured in the main room 400 and the wireless LAN repeater 100 configured in the side room 500 are connected via an outdoor communication path 600, and the wireless LAN repeater 100 is connected via an indoor communication path 700 to one or more first hosts 300 configured in the same side room 500, the wireless LAN system 1000 of the present invention has the following advantages.

[0260] 1) Since the 5GHz W52 band, W53 band and 6GHz LPI band, which are prohibited for outdoor use, are not used in the connection between the wireless LAN router 200 and the wireless LAN repeater 100, it does not violate the law.

[0261] 2) By selecting the most suitable communication environment among the 6GHz VLP and 5GHz W56 bands that allow communication outdoors to connect to the wireless LAN router 200, the communication capacity of the connection to the wireless LAN router 200 can be further increased.

[0262] 3) If radar waves are detected by wireless LAN router 200 or wireless LAN repeater 100 in the 5GHz W56 band, use either of the following two methods.

[0263] In the first method, a connection is first attempted on another channel in the 5GHz W56 band. If the connection fails, the wireless LAN router 200 and the wireless LAN repeater 100 are restarted. Therefore, reliable compliance with laws based on improved radar detection accuracy during radar detection and suppression of the processing load on the wireless LAN repeater 100 can be achieved.

[0264] In the second method, a connection is first established with a wireless LAN repeater 100 at 6 GHz or 2.4 GHz, and then a connection is attempted on another channel in the 5 GHz W56 band. Therefore, reliable compliance with laws based on improved radar detection accuracy can be achieved during radar detection, avoiding the at least one minute of communication interruption required for radar detection.

[0265] 4) By periodically attempting to recover to the 6GHz VLP band or the 5GHz W56 band, which have large communication capacity, the cumulative communication capacity can be increased.

[0266] It should be noted that the configuration of the wireless LAN router 200 and the wireless LAN repeater 100 sometimes changes from their initial configuration. Therefore, the wireless LAN router 200 and the wireless LAN repeater 100 not only have a room mode, but also preferably have a conventional mode that uses all frequency bands of the 2.4GHz, 5GHz, and 6GHz bands for the connection between the wireless LAN router 200 and the wireless LAN repeater 100, as well as the connection with the hosts 300 and 300a.

[0267] Furthermore, it is preferable to configure the switching between the two modes so that users can clearly see which mode the wireless LAN router 200 and the wireless LAN repeater 100 are using. From the viewpoint of preventing accidental operation and ensuring clarity, the mode switching switch is preferably a slide switch located on the side of the housing of the wireless LAN router 200 and the wireless LAN repeater 100. Additionally, LEDs provided on the housing can indicate which communication mode is in use, and also indicate which frequency band the wireless LAN router 200 and the wireless LAN repeater 100 are using for communication. Furthermore, by displaying the communication status (radio wave strength, etc.) of the wireless LAN router 200 and the wireless LAN repeater 100 using LEDs or similar displays, it is also easier to find the most suitable installation location for high-capacity, high-speed communication.

[0268] In addition, Figure 1In the wireless LAN system 1000, the wireless LAN router 200 and the wireless LAN repeater 100 each have multiple SSIDs. The SSID of the connection between the wireless LAN router 200 and the second host 300a is the same as the SSID of the connection between the wireless LAN repeater 100 and the first host 300. Alternatively, the SSID of the connection between the wireless LAN router 200 and the wireless LAN repeater 100 may be different from the same SSID.

[0269] At this time, since the first host 300 and the second host 300a are configured with the same SSID, the wireless LAN connection can be maintained even if the second host 300a (e.g., a smartphone) used in the main room 400 is moved to the side room 500.

[0270] Furthermore, since the SSIDs of the connection between the wireless LAN router 200 and the wireless LAN repeater 100 and the connection between the wireless LAN router 200 or the wireless LAN repeater 100 and the hosts 300 and 300a are different, for example, the connection between the wireless LAN router 200 and the wireless LAN repeater 100 can be mapped to VLP, and the connection between the wireless LAN router 200 or the wireless LAN repeater 100 and the hosts 300 and 300a can be mapped to LPI.

[0273] exist Figure 13 In the configuration, since the wireless LAN router 200 and the second wireless LAN repeater 120 are connected via an indoor communication path 720, and the second wireless LAN repeater 120 and the wireless LAN repeater 100 are connected via an outdoor communication path 600, the connection between the second wireless LAN repeater 120 and the first wireless LAN repeater 100 is preferably set to an outdoor communication path specification, and the wireless LAN repeater 100 is set to a room mode.

[0274] At this point, the wireless LAN router 200 and the first host 300 can connect without violating any laws and regulations, and with the maximum possible communication capacity.

[0275] [Wireless LAN System 1000b of Embodiment 4]

[0276] Figure 14 This is a schematic diagram of a wireless LAN system 1000b of the fourth embodiment, which consists of a wireless LAN router 200 of the second embodiment configured in the main room 400, a first wireless LAN repeater 100 of the first embodiment configured in the side room 500, a third wireless LAN repeater 130, and a first host 300.

[0277] exist Figure 14 In the configuration, since the wireless LAN router 200 and the first wireless LAN repeater 100 are connected by an outdoor communication path 600, and the first wireless LAN repeater 100 and the third wireless LAN repeater 130 are connected by an indoor communication path 730, it is preferable to set the wireless LAN router 200 and the first wireless LAN repeater 100 to a room mode, and set the third wireless LAN repeater 130 to a normal mode.

[0278] At this point, the wireless LAN router 200 and the first host 300 can connect without violating any laws and regulations, and with the maximum possible communication capacity.

[0279] [Wireless LAN System 1000c of the Fifth Embodiment]

[0280] Figure 15 This is a schematic diagram of a wireless LAN system 1000c of a fifth embodiment, consisting of a wireless LAN router 200 of the second embodiment configured in the main room 400, a fourth wireless LAN repeater 140 of the first embodiment configured in the first side room 510, a first wireless LAN repeater 100 of the first embodiment configured in the second side room 520, and a first host 300.

[0281] exist Figure 15 In the configuration, since the wireless LAN router 200 and the fourth wireless LAN repeater 140 are connected by an outdoor communication path 640, and the fourth wireless LAN repeater 140 and the first wireless LAN repeater 100 are connected by an outdoor communication path 600, when the wireless LAN router 200, the fourth wireless LAN repeater 140 and the first wireless LAN repeater 100 are set to the room mode, the outdoor communication path specifications need to be set for the connection between the fourth wireless LAN repeater 140 and the wireless LAN repeater 100.

[0282] At this point, the wireless LAN router 200 and the host 300 can connect without violating any laws and regulations, and with the maximum possible communication capacity.

It should be understood that various other embodiments can be implemented without departing from the spirit and scope of the present invention.
