Different versions of Wi-Fi exist, with different ranges, radio bands and speeds. Wi-Fi most commonly uses the 2. In 1971, ALOHAnet connected the Hawaiian Islands with a UHF wireless packet network. ALOHAnet and the ALOHA protocol were early forerunners to Ethernet, and later the IEEE 802. A 1985 ruling by the U. Federal Communications Commission released the ISM band for unlicensed use.

These frequency bands are the same ones used by equipment such as microwave ovens and are subject to interference. T Corporation invented the precursor to 802. 11, intended for use in cashier systems, under the name WaveLAN. The first version of the 802. This was updated in 1999 with 802. In 1999, the Wi-Fi Alliance formed as a trade association to hold the Wi-Fi trademark under which most products are sold. Wi-Fi uses a large number of patents held by many different organizations.

1 billion for infringements on CSIRO patents. The name Wi-Fi, commercially used at least as early as August 1999, was coined by the brand-consulting firm Interbrand. The Wi-Fi Alliance had hired Interbrand to create a name that was “a little catchier than ‘IEEE 802. Interbrand also created the Wi-Fi logo. The yin-yang Wi-Fi logo indicates the certification of a product for interoperability.

The Wi-Fi Alliance used the nonsense advertising slogan “The Standard for Wireless Fidelity” for a short time after the brand name was created. Non-Wi-Fi technologies intended for fixed points, such as Motorola Canopy, are usually described as fixed wireless. Ad-hoc mode was first invented and realized by Chai Keong Toh in his 1996 invention of Wi-Fi ad-hoc routing, implemented on Lucent WaveLAN 802. The IEEE does not test equipment for compliance with their standards.

Specifically, the certification process requires conformance to the IEEE 802. 11 radio standards, the WPA and WPA2 security standards, and the EAP authentication standard. Certification may optionally include tests of IEEE 802. Not every Wi-Fi device is submitted for certification.

The lack of Wi-Fi certification does not necessarily imply that a device is incompatible with other Wi-Fi devices. A Japanese sticker indicating to the public that a location is within range of a Wi-Fi network. A dot with curved lines radiating from it is a common symbol for Wi-Fi, representing a point transmitting a signal. To connect to a Wi-Fi LAN, a computer has to be equipped with a wireless network interface controller.
