The WiFi alliance
The Wi-Fi Alliance is a trade association that promotes Wireless LAN technology and certifies products if they conform to certain standards of interoperability. Not every IEEE 802.11-compliant device is submitted for certification to the Wi-Fi Alliance, sometimes because of costs associated with the certification process. The lack of the Wi-Fi logo does not necessarily imply a device is incompatible with Wi-Fi devices.
Early 802.11 products suffered from interoperability problems because the IEEE has no provision for testing equipment for compliance with its standards. (ME YOU NOT TALK).
In 1999, pioneers of a new, higher speed (compared to the original 802.11) spec, endorsed the IEEE 802.11b specification to form the Wireless Ethernet Compatibility Alliance (WECA) and branded the new technology Wi-Fi.
The group of companies included 3Com, Aironet (now Cisco), Harris Semiconductor(now Intersil) , Lucent (now Alcatel-Lucent), Symbol Technologies (now Motorola), and Nokia. As key sponsors, now the Alliance lists other companies, such as Apple inc. and Microsoft. The charter for this independent organization was to perform testing, certify interoperability of products, and to promote the technology.
WECA renamed itself the Wi-Fi Alliance in 2002.It is based in Austin, Texas.
Today, most producers of 802.11 equipment are members, and as of 2010, the Wi-Fi Alliance has over 375 member companies worldwide.
