Two points to be aware of when introducing a home router - PHILE WEB

"Home routers" that share 4G/5G lines at home via Wi-Fi are popular. The 5G line area is still in the developing stage, but even with a 4G line, you can achieve a reasonable speed and do not need construction or wiring. But home routers are not a panacea. If your home is within the 5G area, high-speed Internet access exceeding 200 or 300 Mbps is possible on an effective basis, but there are two weak points that you should understand before introducing it.

An example of a home router, docomo "home 5G" One of them is "high PING value". The PING value is a numerical value of the time it takes to send and receive data, and represents the line response and response speed. A lower value means better response speed/response, but home routers that use 4G/5G lines are slightly higher than optical fiber lines. When using content that requires low latency, such as FPS online games, you should be prepared to be at a disadvantage. It is also necessary to understand that in principle you cannot use it outside the registered address. As of February 2022, all home routers affiliated with the three major carriers (docomo, au, and Softbank) are required to be used at the registered address, so they cannot be used outside the home (if you change the address, you can do it). Please note that you cannot carry it around like a mobile router, as you may be subject to penalties as a violation of the contract if you use it at a new location.
