[Q] Should I buy a Wi-Fi router I bought 10 years ago?
[A] By replacing the latest Wi-Fi router, the communication speed can be greatly improved.
The main communication standard of Wi-Fi is "IEEE 802 in the old order..11a "," IEEE 802.11b "," IEEE 802.11g "," IEEE 802.11n (Wi-Fi 4), "IEEE 802.11ac (Wi-Fi 5), "IEEE 802.There is 11ax (Wi-Fi 6).
| 規格 | 最大通信速度 | 規格策定時期 |
| IEEE 802.11a | 54Mbps | 1999年 |
| IEEE 802.11b | 11Mbps | 1999年 |
| IEEE 802.11g | 54Mbps | 2003年 |
| IEEE 802.11n（Wi-Fi 4） | 600Mbps | 2009年 |
| IEEE 802.11ac（Wi-Fi 5） | 6.9Gbps | 2014年 |
| IEEE 802.11ax（Wi-Fi 6） | 9.6Gpbs | 2021年 |
Devices connected to Wi-Fi, such as laptops, smartphones, and tablet devices, basically support not only new standards but also old Wi-Fi communication standards.Therefore, it is possible to connect the latest laptop or smartphone to the Wi-Fi router purchased 10 years ago.
However, when connecting devices such as laptops to a Wi-Fi router and communicating, the latest Wi-Fi communication standards that both are in common.For this reason, for example, a laptop is the latest IEEE 802.Even if it supports 11ax, the Wi-Fi router is compatible with IEEE 802.If it is 11n, the standard used for communication with Wi-Fi is IEEE 802..It is 11n, and the communication speed is only 600Mbps.
Therefore, I want to consider a new Wi-Fi router, IEEE 802.If you use a Wi-Fi router corresponding to 11ax, the communication speed will be greatly improved.
If the communication speed is improved in this way, for example, the response when accessing a website will be faster and can be viewed comfortably, and even a high -resolution video such as full HD and 4K does not fall off due to lack of speed.It will be possible to play.
