What is the full name of wifi?

the term Wi-Fi refers to Wireless Fidelity. the Wi-Fi alliance itself often uses the word "wireless fidelity" in press releases and documents, and wi-fi still appears in a paper of ITAA. However, according to Philbee Langer's statement, Wi-Fi terms should be meaningless. The first version of IEEE 82.11 was published in 1997, which defined the medium access control layer and the physical layer. The physical layer defines two wireless FM modes and one infrared transmission mode working in ISM band of 2.4GHz, and the total data transmission rate is designed to be 2 Mbit/s. The communication between two devices can be carried out in an ad hoc manner, or under the coordination of a Base Station (BS) or an Access Point (AP). \ xd \ \ xd \ added two supplementary versions in 1999: 82.11a defined a physical layer with a data transmission rate of 54Mbit/s in the 5GHz ISM band, and 82.11b defined a physical layer with a data transmission rate of 11Mbit/s in the 2.4GHz ISM band. \xd\ \xd\2.4GHz ISM band is common to most countries in the world, so 82.11b has been widely used. Apple named its own 82.11 standard AirPort. In 1999, the industry set up a Wi-Fi alliance to solve the problems of production and equipment compatibility of products conforming to the 82.11 standard. Wi-Fi is the organization that formulates the 82.11 wireless network, and does not represent the wireless network.
