What does wifi connection speed mean?

The connection speed in wifi is the theoretical data transmission speed. WiFi connection speed and Internet speed are not the same concept. WiFi connection speed must be greater than Internet speed to be stable.

wifi connection speed is the speed of the connection between the router and the Internet device. Generally, the mainstream routers are above 150M, and the Internet speed refers to the operator The speed of the network interface provided, such as adsl, started at 2M in the early days. Now the optical fiber can run at 100M, so if the router speed is only 54M at this time, even using 100M optical fiber can only be limited to the speed of 54M.

To sum up, wifi Internet speed generally depends on the interface speed provided by the operator. As long as the wireless speed of the router is greater than or equal to 150M, it will be sufficient. However, please note that the distance should not exceed 5M, otherwise the wifi signal will be seriously lost. If it cannot reach the nominal strength, the Internet will be slowed down.

Wi-Fi is a technology that allows electronic devices to connect to a wireless local area network (WLAN), typically using the 2.4G UHF or 5G SHF ISM radio frequency bands. Connections to a WLAN are usually password protected; but can also be open, allowing any device within range of the WLAN to connect.

Wi-Fi is a brand of wireless network communication technology, owned by the Wi-Fi Alliance. The purpose is to improve the interoperability between wireless network products based on the IEEE 802.11 standard. Some people call a local area network using the IEEE 802.11 series of protocols wireless fidelity. Wi-Fi is even equated with wireless Internet (Wi-Fi is an important part of WLAN).

Regarding the pronunciation of the abbreviation "Wi-Fi", according to the pronunciation notes of the English Standard Webster Dictionary, the standard pronunciation is /ˈwaɪ.faɪ/ because the word Wi-Fi is composed of two words, Therefore, the best writing format is WI-FI, so that there is no pronunciation problem as mentioned by experts. The same is true for HI-FI (/haɪ.faɪ/).

In August 2014, network security researcher Ruben Santamarta said that if the aircraft WiFi is too open, it may be used by hackers to hijack the aircraft.
