ABSTRACT
The term Wi-Fi, first used commercially in August 1999, was coined by a brand-consulting firm called Inter-brand Corporation. The Wi-Fi Alliance had hired Inter-brand to determine a name that was "a little catchier than 'IEEE 802.11b Direct Sequence'". Belanger also stated that Inter-brand invented Wi-Fi as a play on words with Hi-Fi (high fidelity), and also created the Wi-Fi logo.
The Wi-Fi Alliance initially used the advertising slogan, "The Standard for Wireless Fidelity” for Wi-Fi but later removed the phrase from their marketing. Despite this, some documents from the Alliance dated 2003 and 2004 still contain the term Wireless Fidelity. There was no official statement related to the dropping of the term. The yin-yang Wi-Fi logo indicates the certification of a product for interoperability. Non-Wi-Fi technologies intended for fixed points such as Motorola Canopy are usually described as fixed wireless. Alternative wireless technologies include mobile phone standards such as 2G, 3G or 4G.
Wi-Fi certification
Wi-Fi Alliance
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. As of 2010, the Wi-Fi Alliance consisted of more than 375 companies from around the world. The Wi-Fi Alliance enforces the use of the Wi-Fi brand to technologies based on the IEEE 802.11 standards from the Institute of Electrical and Electronics Engineers. This includes wireless local area network (WLAN) connections, device to device connectivity (such as Wi-Fi Peer to Peer aka Wi-Fi Direct), Personal area network (PAN), local area network (LAN) and even some limited wide area network (WAN) connections. Manufacturers with membership in the Wi-Fi Alliance, whose products pass the certification process, gain the right to mark those products
