Wi-Fi is the trademark of the manufacturer of Wi-Fi alliance. As the brand authentication of products, it is a wireless LAN technology created in IEEE 802.5438+05438+0 standard.
Based on the close relationship between the two systems, Wi-Fi is often regarded as synonymous with IEEE 802. 1 1 standard. "Wi-Fi" is often written as "Wifi" or "WiFi", but they are not recognized by the Wi-Fi alliance.

The wireless network technology was invented by CSIRO, a research institute under the Australian government, in the 1990s, and successfully applied for the wireless network technology patent in the United States on 1996. The inventor is a research team led by Dr. john O'Sullivan, an engineering graduate from the University of Sydney.
IEEE once asked the Australian government to give up the wireless network patent and let the world use Wi-Fi technology for free, but it was rejected.
The Australian government subsequently won the lawsuit or settled out of court in the United States, and incorporated almost all electrical and telecommunications companies in the world (including Apple, Intel, Lenovo, Dell, AT & amp； T, Sony, Toshiba, Microsoft, Acer, ASUS, etc. ).
Every time we buy an electronic device with Wi-Fi technology, the price we pay includes the patent fee paid to the Australian government.
