What Does Wi-Fi Stand For?

Wi-Fi (pronounced: /ˈwaɪfaɪ/) is also known in Chinese as “Mobile Hotspot”. It is a trademark of the Wi-Fi Alliance manufacturers as a brand certification for products, and is a wireless local area network technology based on the IEEE 802.11 standard.

The term Wi-Fi is commonly misunderstood to mean Wireless Fidelity, and even the Wi-Fi Alliance itself often uses the term “Wireless Fidelity” in press releases and documents. Wi-Fi also appears in a paper from the ITAA. However, in reality, the term Wi-Fi has no meaning and does not have a full form.

Example: Free Wi-Fi served at all McDonald’s restaurants.

McDonald’s restaurants offer free Wi-Fi.

The Wi-Fi password in English is expressed as “Wi-Fi password”.

If you want to ask someone for the Wi-Fi password, you can say “What is the Wi-Fi password?” or “Can I have the Wi-Fi password, please?”

Now that we’ve talked about Wi-Fi, do you know what WLAN means?

WLAN stands for Wireless Local Area Network, which means 无线局域网 in Chinese.

It refers to a network system that connects computer devices using wireless communication technology, enabling them to communicate with each other and share resources. The essential feature of a wireless local area network is that it does not use communication cables to connect computers to the network, but rather connects them wirelessly, making network construction and terminal mobility more flexible.

Note that the pronunciation is: / ˌdʌbljuː ˈlæn /.

Overall, Wi-Fi is a specific implementation within WLAN, representing a particular wireless network technology, while WLAN is a more general concept encompassing various wireless local area network technologies.
