Build mesh Wi-Fi at an affordable price Buffalo's Wi-Fi 6 router / relay machine to support "Wi-Fi EasyMesh": models after 2019 are supported
Buffalo is wi-Fi 6 (IEEE 802 (IEEE 802) released by the company since June 3.In the router and relay aircraft corresponding to 11AX), we will promote the mesh Wi-Fi standard "Wi-Fi EasyMesh".As a result, a mesh Wi-Fi network can be easily constructed using a Wi-Fi router or a relay machine corresponding to the standard.
バッファローのWi-Fi 6ルーター／中継機がWi-Fi Easy Meshに対応する方針What is "Wi-Fi EasyMesh"?
"Mesh Wi-Fi", which builds a lattice wireless LAN network, has been realized by each manufacturer using its own standards.Buffalo also released its own mesh Wi-Fi router / relay machine under the brand "AirStation Connect" in 2018.
However, in the mesh Wi-Fi of the manufacturer's own standard, all routers and relay machines need to be prepared with the same manufacturer.Therefore, in order to build a mesh Wi-Fi environment, it is often necessary to replace the whole router or relay machine "whole".If you buy a new device at once, it will be disadvantageous in terms of cost.
バッファローは2018年、独自規格のメッシュWi-Fi製品「AirStation connect」を発売している。独自規格は高度な機能に対応しやすい一方で、イニシャルコストがかさみやすいというデメリットもあるOn the other hand, general Wi-Fi relay aircraft operate regardless of the other party's Wi-Fi router manufacturer, and the price is reasonable.However, since it is recognized as one of the client devices (slind unit) by the router (parent unit), it is not possible to respond to parent -child coordination, such as a rejuvenation (handover) according to the strength of the radio waves.
一般的なWi-Fi中継機は手頃なのがメリットだが、親機との協調動作ができないことが課題であるSo IEEE 802.Wi-Fi Alliance, which is working on standardization of the 11 series wireless LAN standard, has formulated Wi-Fi EasyMesh as a mesh Wi-Fi standard that can be used regardless of manufacturer.A device that complies with the standard can build a mesh Wi-Fi environment regardless of the combination of the manufacturer.
There have already been multiple wireless LAN routers and relay machines that support Wi-Fi EasyMesh.However, almost no manufacturers are appealing in Japan.
Wi-Fi EasyMeshは、一般的な中継機の気軽さを備えつつ、自動経路選択（協調動作による接続先の自動変更）など、メッシュWi-Fiならではの高度な機能も利用できる。有線LANベースのメッシュネットワークも構築できることがメリットだBuffalo is compatible with more advanced "Release 2"
Wi-Fi EasyMesh has two versions of the initial version of "Release 1" and "Release 2" that supports more advanced functions.Many of the current Wi-Fi EasyMesh compatible devices are compliant with Release 1, but all the buffalo compatible products comply with Release 2.
The functions that can be used in Release 2 are as follows.
( * 1) Dynamic frequency selection: A function to automatically scan the frequency band that can be used in the 5GHz band wireless LAN ( * 2) IEEE 802.Compatible with 11R standards
バッファローのWi-Fi EasyMesh対応製品は、Release 2に準拠する。オプション機能となる高速ローミング（IEEE 802.11r）も利用できる。Buffalo's Wi-Fi EasyMesh product also uses a high-speed roaming function that is an optional function of Release 2.High -speed roaming also requires correspondence to the client device side, but in normal roaming, it may be a few seconds to change, but in high -speed roaming can be performed in an instant.According to the company's proprietary verification, it has been confirmed that high -speed roaming can be used on many high -end smartphones.
The device that supports Release 2 can be combined with a device compliant with Release 1.However, in this case, be aware that the functions added in Release 2 cannot be used.
Wi-Fi Easy Meshでは、IEEE 802.11k（ルーターと中継機の情報をクライアント機器に伝達するための規格）とIEEE 802.11v（クライアント機器にローミングを指示するための規格）への対応が必須となる。IEEE 802.11r（高速ローミング）への対応は Release 2においてオプション機能として盛り込まれたが、バッファローの対応機器では全モデルで対応するバッファローが独自に検証した、スマートフォンのローミング規格への対応状況。iPhoneでは、比較的最近の機種なら完全に対応できるWi-Fi EasyMeshでは、有線LANでつないだ複数の対応ルーターを使ってメッシュWi-Fiネットワークを構築できる。メッシュネットワークを無線で構築しづらい環境でも便利に使える（有線LANケーブルの配線が必要となるが）For Buffalo's compatible products, 2 radio bands for mesh networks are 2.It has a unique function to automatically switch between 4GHz band and 5GHz band.For example, 2 for mesh network.When the radio waves of the 4GHz band are used, when the microwave oven starts to move, it automatically switches to the 5GHz band.Conversely, if you use a 5GHz band radio wave for the mesh network, you will automatically detect a continuous signal in the 5GHz band 2..Switch to 4GHz band.
The setup supports not only WPS / AOSS but also negotiations by wired LAN.
メッシュネットワーク用に利用する電波帯域を自動で切り替える機能は、バッファロー独自の機能であるコントローラー（親機）とエージェント（子機）のセットアップは、WPS／AOSSだけではなく有線LANでの直結でも行えるScheduled to be supported
As mentioned earlier, the Wi-Fi EasyMesh will be compatible with the Wi-Fi 6 compatible router / relay machine released after 2019.In each case, it is necessary to update the firmware.The specific models to be supported are as follows.
ルーター
The router can be used as either Wi-Fi EasyMesh's "controller (parent unit)" or "agent (child unit)".
2019年10月に発売されたハイエンドルーター「WXR-5950AX12」もWi-Fi EasyMeshに対応する予定中継機
The relay machine can only be used as an agent of Wi-Fi EasyMesh.
