In 1971, ALOHAnet connected the Hawaiian Islands with a UHF wireless packet network. Federal Communications Commission released the ISM band for unlicensed use.

Wi-Fi or Wi Fi is a technology for wireless local area networking with devices based on the IEEE 802.11 standards.

Wi-Fi is a trademark of the Wi-Fi Alliance, which restricts the use of the term Wi-Fi Certified to products that successfully complete interoperability certification testing.

The IEEE does not test equipment for compliance with their standards.

The non-profit Wi-Fi Alliance was formed in 1999 to fill this void — to establish and enforce standards for interoperability and backward compatibility, and to promote wireless local-area-network technology.

Alternative wireless technologies include mobile phone standards, such as 2G, 3G, 4G, and LTE.

The name is often written as Wi Fi, Wifi, or wifi, but these are not approved by the Wi-Fi Alliance.

Devices that can use Wi-Fi technology include personal computers, video-game consoles, smartphones, digital cameras, tablet computers, digital audio players and modern printers.
