Wi-Fi stands for Wireless Fidelity, which reflects its role in providing wireless connectivity and data transmission within a local area network. The term "fidelity" in this context implies the reliable transmission and reception of data without the need for physical cabling, emphasizing the connection's integrity.

The name was developed by the Wi-Fi Alliance to create a brand that conveys the technology's essence as a wireless networking method. Although "Wi-Fi" was originally coined as a catchy term and does not have a formal expansion in terms of technical specifications, "Wireless Fidelity" has become widely accepted in the industry and among users to indicate its functionality and reliability in networking contexts.
