Wi-Fi

The Wi-Fi Alliance is a non-profitorganization that owns the Wi-Fi trademark.

Wi-Fi does not actually stand for anything, it is not an abbreviation or an acronym. While many believe it stands for “Wireless Fidelity”

Wi-Fi is a protected brand name, companies cannot freely label anything “Wi-Fi” unless they are authorized, it is used to identify products that follow IEEE 802.11-based interoperability expectations.

Wi-Fi Certified

Wi-Fi Alliance restricts the use of the term “Wi-Fi Certified” to products that successfully complete interoperability certification testing. Non-compliant hardware is simply referred to as WLAN, and it may or may not work with “Wi-Fi Certified” devices. As of 2017, the Wi-Fi Alliance consisted of more than 800 companies from around the world. As of 2019, over 3.05 billion Wi-Fi-enabled devices are shipped globally each year.

Wi-Fi Certified is a compliance certification program that means a device has passed interoperability tests defined by the Wi-Fi Alliance. Tests include:

correct implementation of IEEE 802.11 PHY/MAC behavior
authentication compatibility
roaming behavior
power saving modes
coexistence with other devices
performance under interference

802.11

IEEE 802.11 is part of the IEEE 802 set of local area network (LAN) technical standards, and specifies the set of medium access control (MAC) and physical layer (PHY) protocols for implementing wireless local area network (WLAN) computer communication.

The standard and amendments provide the basis for wireless network products using the Wi-Fi brand and are the world’s most widely used wireless computer networking standards. IEEE 802.11 is used in most home and office networks to allow laptops, printers, smartphones, and other devices to communicate with each other and access the Internet without connecting wires.
