When connecting to the Internet using Wi-Fi at home, install a router connected to the Internet and use Wi-Fi Configure your Internet environment. By setting the router's SSID and security code on your computer or smartphone, you will be able to communicate with the router.
Wi-Fi signals are sent from your router. For example, in the 2.4GHz band of the 11g standard, it is "theoretically" possible to transmit at the maximum speed with a line-of-sight distance of nearly 20m at maximum output.
But in reality, you can only communicate at a slower speed than that. Also, if there is an obstacle such as a concrete wall between the terminal and the router, this distance will be further shortened. There are probably many people who have had the experience of trying to use their smartphone or computer in their room, but the Wi-Fi signal was weak, and they had no choice but to search around for a location with a strong signal.
The high-frequency radio waves used in Wi-Fi are known to travel in a straight line and are vulnerable to obstacles. For example, just a few walls between the device and the router can make it difficult for radio waves to reach the area.
However, to solve this problem, it is not realistic to install an internet line in each room and install a dedicated router in each room. Mesh Wi-Fi is a solution to these problems.
In mesh Wi-Fi, in order to configure a Wi-Fi area, three or more devices, including the "main router" that connects to the Internet and the "satellite router" that serves as an intermediate route, form a mesh. Configure.
The main router and the satellite routers communicate, divide the work and emit radio waves, distribute the radio waves to various necessary places, and build a large Wi-Fi network.
For the terminal, the mesh Wi-Fi area constructed by this main router and satellite routers looks the same regardless of whether it is the area created by the main router or the area of the satellite routers. You can connect/communicate in the same way even if you are connected to
The more satellite routers you install, the finer the network of radio waves, and the more places the terminal has strong radio waves.
Also, the farther you place it, the more coverage you can receive. For example, in the case of a 2-3 story house, if the main router is placed in the living room on the 1st floor and the satellite routers are installed on the 2nd and 3rd floors, the You can use it as if you were there. Also, if there is a place on the second floor where it is difficult for radio waves to pass through, adding a satellite router on the second floor will improve the radio wave environment.
