近年、無線ＬＡＮにおいて、２．４ＧＨｚ帯と５ＧＨｚ帯とが使用可能となり、さらに５ＧＨｚ帯では、５．２ＧＨｚ帯のＷ５２、５．３ＧＨｚ帯のＷ５３、５．６ＧＨｚ帯のＷ５６が使用可能となっている。これに伴って、無線ＬＡＮの通信機能を搭載した、ルータ、リピータ（ルータとホストとを接続する中継機能を有する通信機）、およびコンピュータ等のホストにおいても、２．４Ｇ、Ｗ５２、Ｗ５３、Ｗ５６のすべての周波数での通信機能を備えたものが広く提供されている。
しかし、５．２ＧＨｚ帯の周波数は、衛星通信システムのフィーダリンクと周波数が重複し、また、５．３ＧＨｚ帯および５．６ＧＨｚ帯は気象レーダーと周波数が重複ないし隣接するために、家庭用の無線ＬＡＮでは、各周波数帯域ごとに使用上の制限が課されている。下記表１に周波数帯域ごとの制約を示す。 In recent years, 2.4 GHz band and 5 GHz band can be used in wireless LAN, and in 5 GHz band, W52 in 5.2 GHz band, W53 in 5.3 GHz band, and W56 in 5.6 GHz band can be used. There is. Along with this, 2.4G, W52, W53, W56 also in hosts such as routers, repeaters (communication devices having a relay function for connecting routers and hosts), and computers equipped with wireless LAN communication functions. Those equipped with communication functions at all frequencies of are widely provided.
However, the frequency of the 5.2 GHz band overlaps with the feeder link of the satellite communication system, and the frequency of the 5.3 GHz band and the 5.6 GHz band overlaps with or is adjacent to the weather radar. In LAN, usage restrictions are imposed for each frequency band. Table 1 below shows the restrictions for each frequency band.

Figure 2022014024000002
Figure 2022014024000002

表１に記載のように、２．４ＧＨｚ帯およびＷ５６帯は屋内および屋外で使用可能であるが、Ｗ５２帯およびＷ５３帯は屋内でのみ使用可能である。
また、ＤＦＳ（Ｄｙｎａｍｉｃ Ｆｒｅｑｕｅｎｃｙ Ｓｅｌｅｃｔｉｏｎ）とは主に気象観測用として使われているＣバンドレーダーへの悪影響を避けるため、無線ＬＡＮ機器にレーダー電波の検出と、検出時の発信停止（および他チャンネルへの移動）を義務付けたものであるが、Ｗ５３帯、およびＷ５６帯においてＤＦＳの機能の搭載が義務付けられている。
また、ＴＰＣ（Ｔｒａｎｓｍｉｔ Ｐｏｗｅｒ Ｃｏｎｔｒｏｌ）とは干渉回避のために必要に応じて送信出力を下げる規定であるが、同様にＷ５３帯、およびＷ５６帯においてＴＰＣの機能の搭載が義務付けられている。 As shown in Table 1, the 2.4 GHz band and the W56 band can be used indoors and outdoors, while the W52 band and the W53 band can be used only indoors.
Also, DFS (Dynamic WiFi Selection) is to detect radar radio waves in wireless LAN equipment and stop transmission (and to other channels) when it is detected, in order to avoid adverse effects on C-band radar, which is mainly used for meteorological observation. However, it is obligatory to install the DFS function in the W53 band and W56 band.
Further, TPC (Transmit Power Control) is a provision to reduce the transmission output as necessary to avoid interference, but similarly, it is obligatory to install the TPC function in the W53 band and the W56 band.

最近、無線ＬＡＮの利用法として、図６に描かれているように、母屋にルータを置き、離れ家にリピータを置いて、無線ＬＡＮ用ルータと無線ＬＡＮ用リピータの間を無線ＬＡＮで通信し、さらに無線ＬＡＮ用リピータと離れ家の屋内にあるホストとの間をまた無線ＬＡＮで通信するとの利用法が始まっている。
この場合、無線ＬＡＮ用ルータと無線ＬＡＮ用リピータの間は屋外通信経路に相当するため、２．４ＧＨｚ帯またはＷ５６帯を用いて通信しなければならない。しかし、従来の無線ＬＡＮ用ルータおよび無線ＬＡＮ用リピータではＷ５２帯およびＷ５３帯でも技術的には通信可能であるため、無線ＬＡＮ用ルータと無線ＬＡＮ用リピータの間を屋外通信経路を経由してＷ５２帯またはＷ５３帯で接続し、結果的に法律違反を犯している場合もあると考えられる。
また、初期設定時、屋外使用が法律で認められていてかつ通信容量が大きいＷ５６でルータとリピータの間を通信している場合において、無線ＬＡＮ用ルータまたは無線ＬＡＮ用リピータでレーダー電波が検出された場合に、無線ＬＡＮ用ルータおよび無線ＬＡＮ用リピータの制御アルゴリズムによっては、屋外使用が禁止されているＷ５２またはＷ５３に無線周波数帯域が切り換えられる可能性もある。 Recently, as a usage of wireless LAN, as shown in FIG. 6, a router is placed in the main house, a repeater is placed in a remote house, and communication between the router for wireless LAN and the repeater for wireless LAN is performed by wireless LAN. Furthermore, the usage of communicating with a repeater for wireless LAN and a host in a remote house by wireless LAN has begun.
In this case, since the wireless LAN router and the wireless LAN repeater correspond to an outdoor communication path, communication must be performed using the 2.4 GHz band or the W56 band. However, since the conventional wireless LAN router and wireless LAN repeater can technically communicate in the W52 band and the W53 band, the W52 is connected between the wireless LAN router and the wireless LAN repeater via an outdoor communication path. It is considered that there are cases where the connection is made with a band or W53 band, and as a result, the law is violated.
In addition, at the time of initial setting, when outdoor use is permitted by law and communication is performed between the router and the repeater with W56, which has a large communication capacity, the radar radio wave is detected by the router for wireless LAN or the repeater for wireless LAN. In this case, depending on the control algorithm of the wireless LAN router and the wireless LAN repeater, the radio frequency band may be switched to W52 or W53, which are prohibited from outdoor use.

特許文献１に記載の発明では、ベース装置との間で無線通信システムを構成する表示端末５０に当該装置が屋内にあるか屋外にあるかを判断するための検出器を搭載している。しかし、特許文献１に記載の検出器が検出するのは当該装置が屋内にあるか屋外にあるかであって、図６に描かれているような、無線ＬＡＮ用リピータは屋内にあり、無線ＬＡＮ用ルータと無線ＬＡＮ用リピータの間が屋外である場合には屋内と判断されてしまう。 In the invention described in Patent Document 1, the display terminal 50 constituting the wireless communication system with the base 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, and the repeater for wireless LAN as shown in FIG. 6 is indoors and wireless. If the area between the LAN router and the wireless LAN repeater is outdoors, it is determined to be indoors.

また、特許文献２に記載の発明の無線通信装置（無線ＬＡＮ用リピータ）では、ルータと接続される第１の通信部１１がＷ５２帯またはＷ５３帯を使用中である場合、すなわち、ルータとリピータの間が屋内通信経路であると判断される場合にのみ、ホストと接続される第２の通信部１２に対してＷ５２帯とＷ５３帯の使用が許可されている。しかし、図６に描かれているような、無線ＬＡＮ用リピータとホストは屋内にあり、無線ＬＡＮ用ルータと無線ＬＡＮ用リピータの間が屋外通信経路である場合には、無線ＬＡＮ用ルータと無線ＬＡＮ用リピータの間が２．４ＧＨｚまたはＷ５６帯を使用中であっても、無線ＬＡＮ用リピータとホストとの間はＷ５２帯またはＷ５３帯を使用することが可能である。したがって、特許文献２に記載の発明の制御アルゴリズムは、図６に描かれているような使用法に対しては適切でない。 Further, in the wireless communication device (repeater for wireless LAN) of the invention described in Patent Document 2, when the first communication unit 11 connected to the router is using the W52 band or the W53 band, that is, the router and the repeater. The use of the W52 band and the W53 band is permitted for the second communication unit 12 connected to the host only when it is determined that the space between them is an indoor communication path. However, as shown in FIG. 6, when the wireless LAN repeater and the host are indoors and the outdoor communication path is between the wireless LAN router and the wireless LAN repeater, the wireless LAN router and the wireless are used. Even if the 2.4 GHz or W56 band is being used between the LAN repeaters, it is possible to use the W52 band or the W53 band 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 as depicted in FIG.

また、特許文献３に記載の発明は、無線ＬＡＮを搭載した情報通信装置の発明であって、無線ＬＡＮ用リピータにおいて必須の機能であるホストとの通信に関する記載がないこと、また、レーダー電波が検出された場合についての記載がないことから、本発明が解決しようとする課題の解決策とはならない。 Further, the invention described in Patent Document 3 is an invention of an information communication device equipped with a wireless LAN, and there is no description regarding communication with a host, which is an essential function in a repeater for a wireless LAN, and a radar radio wave is used. Since there is no description about the case where it is detected, it is not a solution to the problem to be solved by the present invention.

また、特許文献４に記載の発明では自装置の位置情報を取得し、自機の位置が、屋外で利用されている可能性が高い位置である場合、第１の周波数帯と第２の周波数帯のうち、屋外での利用が認められている周波数帯を用いた無線通信方式を選択する。しかし、特許文献４に記載の発明の場合も位置情報を検出するのは自装置のみであり、したがって、図６に描かれているような、無線ＬＡＮ用リピータとホストは屋内にあり、無線ＬＡＮ用ルータと無線ＬＡＮ用リピータの間が屋外である場合には使用できる無線通信方式に関する判断を誤る可能性がある。
また、特許文献４にもレーダー電波が検出された場合についての記載はない。 Further, in the invention described in Patent Document 4, the position information of the own device is acquired, and when the position of the own device is a position likely to be used outdoors, the first frequency band and the second frequency Of the bands, select a wireless communication method that uses a frequency band that is approved for outdoor use. However, even in the case of the invention described in Patent Document 4, it is only the own device that detects the position information. Therefore, as shown in FIG. 6, the repeater and host for wireless LAN are indoors, and the wireless LAN is used. When the space between the router and the wireless LAN repeater is outdoors, there is a possibility that the judgment regarding the wireless communication method that can be used may be erroneous.
Further, Patent Document 4 does not describe the case where radar radio waves are detected.

本発明の主な目的は、離れ家などに配置されて、母屋などに配置された無線ＬＡＮ用ルータと屋外通信経路を経由して接続される無線ＬＡＮ用リピータにおいて、法律で定められた屋外で使用可能な電波帯域を使用し、かつ、より通信容量の大きな帯域を優先的に使用することのできる、無線ＬＡＮチャンネル切換方法、無線ＬＡＮチャンネル切換方法を備えた無線ＬＡＮ用リピータ、および無線ＬＡＮシステムを提供することにある。
本発明のさらなる目的は、母屋などに配置された無線ＬＡＮ用ルータと屋外通信経路を経由して接続される無線ＬＡＮ用リピータにおいて、無線ＬＡＮ用ルータまたは無線ＬＡＮ用リピータでＷ５６帯のレーザー電波が検出された場合に、いったん２．４ＧＨｚ帯に切り替えるが、通信容量の大きいＷ５６帯への復帰を最大限早めることのできる無線ＬＡＮチャンネル切換方法、無線ＬＡＮチャンネル切換方法を備えた無線ＬＡＮ用リピータ、および無線ＬＡＮシステムを提供することにある。 A main object of the present invention is to use a wireless LAN repeater located in a remote house or the like and connected to a wireless LAN router arranged in a main building or the like via an outdoor communication path, outdoors as stipulated by law. A wireless LAN channel switching method, a wireless LAN repeater equipped with a wireless LAN channel switching method, and a wireless LAN system capable of using a possible radio band and preferentially using a band having a larger communication capacity. To provide.
A further object of the present invention is to use a wireless LAN router or a wireless LAN repeater to generate W56 band laser radio waves in a wireless LAN repeater connected to a wireless LAN router located in a main building or the like via an outdoor communication path. A wireless LAN channel switching method that can switch to the 2.4 GHz band once when detected, but can speed up the return to the W56 band, which has a large communication capacity, and a wireless LAN repeater equipped with a wireless LAN channel switching method. And to provide a wireless LAN system.

一局面に従う無線周波数帯域切換方法は、無線ＬＡＮ用ルータと屋外通信経路を経由して接続されるとともに、１または複数のホストと屋内通信経路により接続される無線ＬＡＮ用リピータの無線周波数帯域切換方法であって、無線ＬＡＮ用リピータが無線ＬＡＮ用ルータに対して５ＧＨｚＷ５６帯での接続を試みる工程と、無線ＬＡＮ用リピータが無線ＬＡＮ用ルータに対して５ＧＨｚＷ５６帯で接続できた場合には、無線ＬＡＮ用リピータは無線ＬＡＮ用ルータに対して５ＧＨｚＷ５６帯での接続を継続し、無線ＬＡＮ用リピータが無線ＬＡＮ用ルータに対して５ＧＨｚＷ５６帯で接続できなかった場合には、無線ＬＡＮ用リピータは無線ＬＡＮ用ルータに対して２．４ＧＨｚ帯で接続する工程と、を備える。 (1)
The wireless frequency band switching method according to one aspect is a wireless frequency band switching method of a wireless LAN repeater connected to a wireless LAN router via an outdoor communication path and connected to one or more hosts by an indoor communication path. If the wireless LAN repeater tries to connect to the wireless LAN router in the 5 GHz W56 band and the wireless LAN repeater can connect to the wireless LAN router in the 5 GHz W56 band, the wireless LAN The repeater for wireless LAN continues to connect to the router for wireless LAN in the 5 GHz W56 band, and if the repeater for wireless LAN cannot connect to the router for wireless LAN in the 5 GHz W56 band, the repeater for wireless LAN is for wireless LAN. It includes a step of connecting to a router in the 2.4 GHz band.

無線ＬＡＮ用ルータを母屋に配置し、無線ＬＡＮ用リピータを母屋と独立した離れ家に配置した場合、無線ＬＡＮ用リピータは屋外通信経路を経由して無線ＬＡＮ用ルータと接続されるため、５ＧＨｚＷ５２帯またはＷ５３帯を屋外で使用した場合には法律違反となる。しかし、一局面に従う無線周波数帯域切換方法では、無線ＬＡＮ用ルータと無線ＬＡＮ用リピータとの間の通信に５ＧＨｚＷ５６帯または２．４ＧＨｚ帯のみを使用するため、衛星通信システムおよび気象レーダーに影響を与える可能性がなく、法律違反となることがない。
また、一局面に従う無線周波数帯域切換方法ではまず５ＧＨｚＷ５６帯で無線ＬＡＮ用ルータと接続を試み、５ＧＨｚＷ５６帯で接続できない場合にのみ２．４ＧＨｚで無線ＬＡＮ用ルータと接続するため、より通信容量の大きな５ＧＨｚＷ５６帯を優先的に使用することができる。 When the wireless LAN router is placed in the main building and the wireless LAN repeater is placed in a remote house independent of the main building, the wireless LAN repeater is connected to the wireless LAN router via the outdoor communication path, so the 5 GHz W52 band or It is against the law to use the W53 band outdoors. However, the radio frequency band switching method according to one aspect affects the satellite communication system and the meteorological radar because only the 5 GHzW56 band or the 2.4 GHz band is used for communication between the wireless LAN router and the wireless LAN repeater. There is no possibility and it does not violate the law.
In addition, in the wireless frequency band switching method according to one aspect, the connection with the wireless LAN router is first attempted in the 5 GHzW56 band, and only when the connection cannot be made in the 5 GHzW56 band, the connection is made with the wireless LAN router at 2.4 GHz, so that the communication capacity is larger. The 5 GHz W56 band can be preferentially used.

（２）
第２の発明にかかる無線周波数帯域切換方法は、一局面に従う無線周波数帯域切換方法において、さらに、無線ＬＡＮ用リピータが無線ＬＡＮ用ルータに対して５ＧＨｚＷ５６帯で接続できた場合には、無線ＬＡＮ用リピータはホストに対して２．４ＧＨｚ帯および／または５ＧＨｚＷ５６帯で接続が可能であることを通知し、無線ＬＡＮ用リピータが無線ＬＡＮ用ルータに対して５ＧＨｚＷ５６帯で接続できなかった場合には、無線ＬＡＮ用リピータはホストに対して２．４ＧＨｚ帯、および／または、５ＧＨｚＷ５２帯、Ｗ５３帯、Ｗ５６帯のうちいずれか１つで接続が可能であることを通知する工程を備えてもよい。 (2)
The wireless frequency band switching method according to the second invention is a wireless frequency band switching method according to one aspect, and further, when a wireless LAN repeater can be connected to a wireless LAN router in the 5 GHzW56 band, it is for wireless LAN. The repeater notifies the host that it is possible to connect in the 2.4 GHz band and / or 5 GHz W56 band, and if the wireless LAN repeater cannot connect to the wireless LAN router in the 5 GHz W56 band, it is wireless. The LAN repeater may include a step of notifying the host that connection is possible in any one of the 2.4 GHz band and / or the 5 GHz W52 band, W53 band, and W56 band.

この場合、無線ＬＡＮ用ルータと５ＧＨｚＷ５６帯での接続が可能な場合と不可能な場合のどちらにおいても、ともに２．４ＧＨｚ帯と、５ＧＨｚ帯のＷ５２帯，Ｗ５３帯，Ｗ５６帯のうちの１つのみを使用することになるため、無線ＬＡＮ用リピータの５ＧＨｚの通信帯域を１つに限定し、無線ＬＡＮ用リピータの回路を簡略化することができる。 In this case, one of the 2.4 GHz band and the 5 GHz band W52 band, W53 band, and W56 band, both when the connection with the wireless LAN router is possible or not possible in the 5 GHz W56 band. Since only the wireless LAN repeater is used, the 5 GHz communication band of the wireless LAN repeater can be limited to one, and the circuit of the wireless LAN repeater can be simplified.

（３）
第３の発明にかかる無線周波数帯域切換方法は、一局面から第２の発明にかかる無線周波数帯域切換方法において、無線ＬＡＮ用リピータが無線ＬＡＮ用ルータと５ＧＨｚＷ５６帯で接続していて、かつ、無線ＬＡＮ用ルータまたは無線ＬＡＮ用リピータが５ＧＨｚＷ５６帯でのレーダーの電波を検出した場合に、無線ＬＡＮ用リピータと無線ＬＡＮ用ルータとの接続を２．４ＧＨｚ帯に切り替えるとともに、無線ＬＡＮ用リピータはレーダーの電波の検出を継続し、一定時間レーダーの電波が検出されなかった場合には、再度無線ＬＡＮ用リピータと無線ＬＡＮ用ルータとの接続を５ＧＨｚＷ５６帯に戻す工程をさらに備えてもよい。 (3)
The wireless frequency band switching method according to the third invention is the wireless frequency band switching method according to the second aspect from the first aspect, in which the repeater for wireless LAN is connected to the router for wireless LAN in the 5 GHzW56 band and is wireless. When the LAN router or wireless LAN repeater detects the radio wave of the radar in the 5GHz W56 band, the connection between the wireless LAN repeater and the wireless LAN router is switched to the 2.4GHz band, and the wireless LAN repeater is the radar. If the radio wave detection is continued and the radio wave of the radar is not detected for a certain period of time, a step of returning the connection between the wireless LAN repeater and the wireless LAN router to the 5 GHzW56 band may be further provided.

この場合、無線ＬＡＮ用ルータまたは無線ＬＡＮ用リピータが５ＧＨｚＷ５６帯でのレーダーの電波を検出した場合に、無線周波数帯域を屋外での使用が禁止されているＷ５２帯、またはＷ５３帯に切り替えることがないため、衛星通信システムおよび気象レーダーに影響を与える可能性がなく、法律違反となることがない。
また、無線ＬＡＮ用リピータと無線ＬＡＮ用ルータとの接続を２．４ＧＨｚ帯に切り替えた場合において、レーダーの電波の検出を継続し、一定時間レーダーの電波が検出されなかった場合には、無線ＬＡＮ用リピータと無線ＬＡＮ用ルータとの接続を５ＧＨｚＷ５６帯に戻すことにより、最短の時間で通信容量の大きなＷ５６に復帰することができる。 In this case, when the wireless LAN router or the wireless LAN repeater detects the radar radio wave in the 5 GHz W56 band, the wireless frequency band is not switched to the W52 band or the W53 band where outdoor use is prohibited. Therefore, there is no possibility of affecting satellite communication systems and meteorological radar, and it does not violate the law.
In addition, when the connection between the wireless LAN repeater and the wireless LAN router is switched to the 2.4 GHz band, the detection of the radar radio wave is continued, and if the radar radio wave is not detected for a certain period of time, the wireless LAN By returning the connection between the repeater and the wireless LAN router to the 5 GHz W56 band, it is possible to return to the W56 having a large communication capacity in the shortest time.

（４）

In the following description, the same parts are designated by the same reference numerals. Further, in the case of the same reference numeral, their names and functions are also the same. Therefore, detailed explanations about them will not be repeated.

［第１の実施形態］
図１は第１の実施形態の、無線ＬＡＮ用ルータ２０、無線ＬＡＮ用リピータ１０、およびホスト３０で構成される無線ＬＡＮシステム１００の模式的構成図であり、図２は本発明の無線周波数帯域切換方法の模式的フローチャートである。本発明の無線周波数帯域切換方法（以降、離れ家モードの無線周波数帯域切換方法とも称する）は、図１の無線ＬＡＮ用リピータ１０に搭載されて用いられる。 [First Embodiment]
FIG. 1 is a schematic configuration diagram of a wireless LAN system 100 composed of a wireless LAN router 20, a wireless LAN repeater 10, and a host 30 according to the first embodiment, and FIG. 2 is a schematic configuration diagram of the wireless frequency band of the present invention. It is a schematic flow chart of the switching method. The wireless frequency band switching method of the present invention (hereinafter, also referred to as a remote house mode wireless frequency band switching method) is mounted on and used in the wireless LAN repeater 10 of FIG.

第１の実施形態の無線ＬＡＮシステム１００では、無線ＬＡＮ用ルータ２０は第１の建物（以降母屋４０と称する）の中に配置され、無線ＬＡＮ用リピータ１０とホスト３０とは第２の建物（以降離れ家５０と称する）の中に配置されている。なお、ホスト３０とは、例えば、無線ＬＡＮを備えたパーソナルコンピュータ、プリンタ、スマートフォンなどである。
無線ＬＡＮ用ルータ２０と無線ＬＡＮ用リピータ１０とは別々の建物に配置されているため、屋外通信経路６０を経由して通信が行われており、無線ＬＡＮ用リピータ１０とホスト３０とは同一の建物の内部に配置されているため、屋内通信経路７０を経由して通信が行われている。
無線ＬＡＮ用リピータ１０は、２．４ＧＨｚ帯の無線ＬＡＮ通信回路と５ＧＨｚＷ５２、Ｗ５３、Ｗ５６帯の無線通信回路を備えており、無線ＬＡＮ用ルータ２０およびホスト３０と、２．４ＧＨｚ帯、５ＧＨｚＷ５２、Ｗ５３、Ｗ５６帯のすべての帯域で通信が可能である。ただし、２．４ＧＨｚ帯と５ＧＨｚ帯のそれぞれにおいて通信することができるのは１つのチャンネルのみである。
したがって、例えば、無線ＬＡＮ用ルータ２０と無線ＬＡＮ用リピータ１０との通信（以下、バックホールともいう）が２．４ＧＨｚ帯で行われている場合は、無線ＬＡＮ用ルータ２０とホスト３０との通信は、２．４ＧＨｚ帯と５ＧＨｚＷ５２、Ｗ５３、Ｗ５６帯のすべての帯域で行うことができるが、バックホールが５ＧＨｚＷ５６で行われている場合は、無線ＬＡＮ用ルータ２０とホスト３０との通信は２．４ＧＨｚ帯と５ＧＨｚＷ５６帯とでしか行うことができない。これは、無線ＬＡＮ用リピータの５ＧＨｚの通信帯域を１つに限定し、無線ＬＡＮリピータの回路を簡略化するためである。 In the wireless LAN system 100 of the first embodiment, the wireless LAN router 20 is arranged in the first building (hereinafter referred to as the main building 40), and the wireless LAN repeater 10 and the host 30 are in the second building (hereinafter referred to as the main building 40). Hereinafter referred to as a remote house 50). The host 30 is, for example, a personal computer, a printer, a smartphone, or the like equipped with a wireless LAN.
Since the wireless LAN router 20 and the wireless LAN repeater 10 are located in separate buildings, communication is performed via the outdoor communication path 60, and the wireless LAN repeater 10 and the host 30 are the same. Since it is located inside the building, communication is performed via the indoor communication path 70.
The wireless LAN repeater 10 includes a 2.4 GHz band wireless LAN communication circuit and a 5 GHz W52, W53, W56 band wireless communication circuit, the wireless LAN router 20 and the host 30, and a 2.4 GHz band, 5 GHz W52, W53. , Communication is possible in all bands of the W56 band. However, only one channel can communicate in each of the 2.4 GHz band and the 5 GHz band.
Therefore, for example, when the communication between the wireless LAN router 20 and the wireless LAN repeater 10 (hereinafter, also referred to as a backhaul) is performed in the 2.4 GHz band, the communication between the wireless LAN router 20 and the host 30 is performed. Can be performed in all bands of 2.4 GHz band and 5 GHz W52, W53, W56 band, but when the backhaul is performed in 5 GHz W56, the communication between the router 20 for wireless LAN and the host 30 is 2. It can be performed only in the 4 GHz band and the 5 GHz W56 band. This is to limit the 5 GHz communication band of the wireless LAN repeater to one and simplify the circuit of the wireless LAN repeater.

（離れ家モードの無線周波数帯域切換方法のフローチャート）
離れ家モードの無線周波数帯域切換方法のフローチャートを図２に示す。
以下、本発明の無線ＬＡＮ用リピータ１０の無線周波数帯域切換方法について、図２のフローチャートを参照して説明する。
まず、無線ＬＡＮ用リピータ１０の電源が投入される、またはリセットボタンが押されると無線周波数帯域切換方法の工程が開始される（ステップＳ１）。
無線ＬＡＮ用リピータ１０は無線ＬＡＮ用ルータ２０のビーコンを入手し、無線ＬＡＮ用ルータ２０との接続が可能な周波数帯域の情報を得る（ステップＳ２）。
無線ＬＡＮ用リピータ１０は無線ＬＡＮ用ルータ２０との接続が２．４ＧＨｚ帯と５ＧＨｚ帯Ｗ５６の両方で可能かどうかを確認する（ステップＳ３）
無線ＬＡＮ用ルータ２０との接続が２．４ＧＨｚ帯と５ＧＨｚＷ５６帯の両方で可能な場合、無線ＬＡＮ用リピータ１０は無線ＬＡＮ用ルータ２０と５ＧＨｚＷ５６帯で接続するとともに、ホスト３０に対してビーコンにより２．４ＧＨｚ帯と５ＧＨｚ帯Ｗ５６の両方で接続が可能であることを通知する（ステップＳ４）。
無線ＬＡＮ用リピータ１０は５ＧＨｚＷ５６帯でのレーダーの電波をモニターする（ステップＳ５）。
５ＧＨｚＷ５６帯でのレーダーの電波が検知されない場合は、レーダーの電波を継続してモニターする（ステップＳ６）。 (Flowchart of radio frequency band switching method in remote house mode)
FIG. 2 shows a flowchart of the radio frequency band switching method in the remote house mode.
Hereinafter, the wireless frequency band switching method of the wireless LAN repeater 10 of the present invention will be described with reference to the flowchart of FIG.
First, when the power of the wireless LAN repeater 10 is turned on or the reset button is pressed, the process of the wireless frequency band switching method is started (step S1).
The wireless LAN repeater 10 obtains the beacon of the wireless LAN router 20 and obtains information on the frequency band that can be connected to the wireless LAN router 20 (step S2).
The wireless LAN repeater 10 confirms whether the connection with the wireless LAN router 20 is possible in both the 2.4 GHz band and the 5 GHz band W56 (step S3).
When the connection with the wireless LAN router 20 is possible in both the 2.4 GHz band and the 5 GHz W56 band, the wireless LAN repeater 10 connects to the wireless LAN router 20 in the 5 GHz W56 band and is connected to the host 30 by a beacon. . Notify that connection is possible in both the 4 GHz band and the 5 GHz band W56 (step S4).
The wireless LAN repeater 10 monitors the radar radio wave in the 5 GHz W56 band (step S5).
If the radar radio wave in the 5 GHzW56 band is not detected, the radar radio wave is continuously monitored (step S6).

ステップＳ６で５ＧＨｚＷ５６帯でのレーダーの電波が検知された場合は、無線ＬＡＮ用リピータ１０は無線ＬＡＮ用ルータ２０との接続を２．４ＧＨｚ帯に切り替えるとともに、ホスト３０に対してビーコンにより２．４ＧＨｚ帯のみで接続が可能であることを通知する（ステップＳ７）。
無線ＬＡＮ用ルータ２０との接続を２．４ＧＨｚ帯に切り替えた後も、無線ＬＡＮ用リピータ１０は継続して５ＧＨｚＷ５６帯でのレーダーの電波をモニターする（ステップＳ８）。
５ＧＨｚＷ５６帯でのレーダーの電波が検知された場合は、レーダーの電波を継続してモニターする（ステップＳ９）。
ステップＳ９で、一定時間レーダーの電波が検知されない場合はステップＳ４に戻り、無線ＬＡＮ用リピータ１０は無線ＬＡＮ用ルータ２０と５ＧＨｚＷ５６帯で接続するとともに、ホスト３０に対してビーコンにより２．４ＧＨｚ帯と５ＧＨｚ帯Ｗ５６の両方で接続が可能であることを通知する。
以降、ステップＳ４からステップＳ９を繰り返す。 When the radar radio wave in the 5 GHz W56 band is detected in step S6, the wireless LAN repeater 10 switches the connection with the wireless LAN router 20 to the 2.4 GHz band, and the host 30 is connected to the host 30 by a beacon at 2.4 GHz. Notify that the connection is possible only with the band (step S7).
Even after the connection with the wireless LAN router 20 is switched to the 2.4 GHz band, the wireless LAN repeater 10 continuously monitors the radar radio wave in the 5 GHz W56 band (step S8).
When the radar radio wave in the 5 GHzW56 band is detected, the radar radio wave is continuously monitored (step S9).
If the radar radio wave is not detected for a certain period of time in step S9, the process returns to step S4, the wireless LAN repeater 10 is connected to the wireless LAN router 20 in the 5 GHz W56 band, and the host 30 is connected to the 2.4 GHz band by the beacon. Notifies that connection is possible in both 5 GHz band W56.
After that, steps S4 to S9 are repeated.

ステップＳ３で、無線ＬＡＮ用ルータ２０との接続が２．４ＧＨｚ帯では可能で、５ＧＨｚ帯Ｗ５６では不可能である場合は、無線ＬＡＮ用リピータ１０は無線ＬＡＮ用ルータ２０と２．４ＧＨｚ帯で接続するとともに、ホスト３０に対してビーコンにより２．４ＧＨｚ帯と５ＧＨｚ帯Ｗ５２，Ｗ５３，Ｗ５６のすべての帯域で接続が可能であることを通知する（ステップＳ１０）。
接続先の無線ＬＡＮ用ルータ２０との接続が５ＧＨｚ帯Ｗ５６で不可能である場合は、以後も無線周波数帯域切換は不要なので、無線周波数帯域切換方法の全工程を終了する（ステップＳ１１）。 In step S3, if the connection with the wireless LAN router 20 is possible in the 2.4 GHz band and not in the 5 GHz band W56, the wireless LAN repeater 10 is connected to the wireless LAN router 20 in the 2.4 GHz band. At the same time, the host 30 is notified by the beacon that the connection is possible in all the 2.4 GHz band and the 5 GHz band W52, W53, W56 (step S10).
If the connection with the connection destination wireless LAN router 20 is impossible in the 5 GHz band W56, the wireless frequency band switching is not required thereafter, so the entire process of the wireless frequency band switching method is completed (step S11).

（離れ家モードの無線周波数帯域切換方法のメリット）
母屋４０の中に配置された無線ＬＡＮ用ルータ２０と屋外通信経路６０を経由して接続され、同じ離れ家５０に配置された１または複数のホスト３０と屋内通信経路７０を経由して接続された無線ＬＡＮ用リピータ１０に、本発明の無線周波数帯域切換方法を設定した場合、以下のメリットがある。
１）無線ＬＡＮ用ルータ２０との接続に屋外使用が禁じられている５ＧＨｚＷ５２帯、Ｗ５３帯を使用することがないため、法律に違反することがない。
２）無線ＬＡＮ用ルータ２０との接続に５ＧＨｚＷ５６帯を優先的に使用するため、無線ＬＡＮ用ルータ２０との接続の通信容量をより大きくすることができる。
３）５ＧＨｚＷ５６帯においてレーダーの電波が検出された場合無線ＬＡＮ用ルータ２０との接続は２．４ＧＨｚ帯に切り替えられるが、２．４ＧＨｚ帯に切り替えた後でも継続してレーダーの電波を検出し、一定時間レーダーの電波が検出されない場合には直ちに５ＧＨｚＷ５６帯に戻すため、無線ＬＡＮ用ルータ２０と接続を最短時間で通信容量の大きな５ＧＨｚＷ５６帯に戻すことができ、累積の通信容量を大きくすることができる。 (Advantages of wireless frequency band switching method in remote mode)
It was connected to the wireless LAN router 20 arranged in the main building 40 via the outdoor communication path 60, and was connected to one or more hosts 30 arranged in the same remote house 50 via the indoor communication path 70. When the wireless frequency band switching method of the present invention is set in the repeater 10 for wireless LAN, there are the following merits.
1) Since the 5 GHz W52 band and W53 band, which are prohibited from outdoor use, are not used for connection with the wireless LAN router 20, there is no violation of the law.
2) Since the 5 GHzW56 band is preferentially used for connection with the wireless LAN router 20, the communication capacity for connection with the wireless LAN router 20 can be further increased.
3) When radar radio waves are detected in the 5 GHz W56 band The connection with the wireless LAN router 20 is switched to the 2.4 GHz band, but even after switching to the 2.4 GHz band, the radar radio waves are continuously detected. If the radar radio wave is not detected for a certain period of time, it immediately returns to the 5GHz W56 band, so the connection with the wireless LAN router 20 can be returned to the 5GHz W56 band, which has a large communication capacity, in the shortest time, and the cumulative communication capacity can be increased. can.

なお、無線ＬＡＮ用ルータ２０および無線ＬＡＮ用リピータ１０の配置は当初の配置位置から変更することがある。したがって、無線ＬＡＮ用リピータ１０には、離れ家モードの無線周波数帯域切換方法だけではなく、無線ＬＡＮ用ルータ２０との接続に２．４ＧＨｚ帯、５ＧＨｚＷ５２帯、Ｗ５３帯、Ｗ５６帯のすべての周波数帯域を使用する、通常モードの無線周波数帯域切換方法も備えておくのが望ましい。また、２種類の無線周波数帯域切換方法の切換は、無線ＬＡＮ用リピータ１０がどちらの無線周波数帯域切換方法で使用されているかがよくわかる、スイッチ等で２種類の無線周波数帯域切換方法を切り換えて使用できるようにすることが望ましい。 The arrangement of the wireless LAN router 20 and the wireless LAN repeater 10 may be changed from the initial arrangement position. Therefore, in the repeater 10 for wireless LAN, not only the method of switching the wireless frequency band in the remote mode but also all the frequency bands of 2.4 GHz band, 5 GHz W52 band, W53 band, and W56 band are used for the connection with the wireless LAN router 20. It is desirable to also have a method for switching the radio frequency band in the normal mode to be used. In addition, when switching between the two types of wireless frequency band switching methods, the two types of wireless frequency band switching methods can be switched with a switch or the like so that the wireless LAN repeater 10 can be clearly identified as to which wireless frequency band switching method is used. It is desirable to be able to use it.
