Wi-Fi Alliance is a non-profit organization that promotes Wi-Fi technology and certifies Wi-Fi 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. The Wi-Fi Alliance owns the ''Wi-Fi'' trademark. Manufacturers may use the trademark to brand certified products that have been tested for interoperability. ==History== Early 802.11 products suffered from interoperability problems because the Institute of Electrical and Electronics Engineers (IEEE) had no provision for testing equipment for compliance with its standards. In 1999, pioneers of a new, higher speed variant, 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 (acquired by Cisco), Harris Semiconductor (now Intersil), Lucent (now Alcatel-Lucent), Nokia and Symbol Technologies (now Motorola). As key sponsors, the alliance lists Apple, Comcast, Samsung, Sony, LG, Intel, Dell, Broadcom, Cisco, Qualcomm, Motorola, Microsoft, Texas Instruments, and T-Mobile. 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. Most producers of 802.11 equipment became members, and , the Wi-Fi Alliance had over 550 member companies. Wi-Fi Alliance extended Wi-Fi beyond wireless local area network applications into point-to-point and personal area networking, and enabled specific applications such as Miracast. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Wi-Fi Alliance」の詳細全文を読む スポンサード リンク
