Wireless Fidelity is a term generally applied to all commercial 802.11 products, but more specifically it refers to products that comply with the WiFi Alliance interoperability certification requirements.
wireless fidelity - is the branding given by the Wireless Ethernet Compatibility Alliance to the IEEE 802.11b standard for wireless interoperability . WiFi enabled devices link together without cables to form wireless local area networks. This has great significance for flexible work and the office of the future. See also Bluetooth.
WiFi is an industry standard that was created to ensure that wireless computer equipement can connect together. It is often associated with "public hotSpot" that allows anyone with a WiFi-compatible laptop to connect to the web.
WiFi (or Wi-Fi) is an abbreviation of 'Wireless Fidelity' and is used to describe the IEEE 802.11 set of wireless LAN/ WAN commmunication protocols, including the most widely used 802.11a, 802.11b and 802.11g.
Wireless Fidelity was originally a brand name licensed by the Wi-Fi Alliance to describe the technology of Wireless Local Area Networks (WLAN) based on the IEEE 802.11 specifications. It is now considered a generic term and is no longer protected as a brand.
WIFI is an abbreviation of Wireless-Fidelty and contains a number of different wireless data standards (802.11) which can be used to connect more devices, typically computers or WIFI telephones, into one network also called a Wireless Local Area Network. Thereby it is possible to use the same ADSL connection or printer between more computers and users. Or it is possible to place a call via the Internet with a WIFI telephone. 802.11 is an open standard developed by the Institute of Electrical and Electronic Engineers (IEEE) and currently consists of four different standards: 802.11, 802.11a, 802.11b and 802.11g. 802.11a operates on the licence-free 5 GHz frequency band, while the others use the 2.4 GHz band. 802.11b is currently the most widespread standard, and can transfer data wirelessly at a speed of 5.5 Mbit/s, with a range of 50-100 metres. 802.11a is four times faster than 802.11b, providing a speed of 27 Mbit/s and a range of 20-100 metres. 802.11g is the latest standard and is just as fast as 802.11a, but operates on the 2.4 GHz frequency band.
Wireless fidelity -- a standard for sending and receiving data -- such as in a home or small office network or LAN (or even an entire city). The standard includes a number of sub-standards under the IEEE's 802.11 standards.()
or Wi-Fi - is Wireless Fidelity or 802.11b. It is a wireless standard capable of far exceeding the data transmission expectations of 3G or third generation. T-Mobile is incorporating in research, and may release a commercial version.
Short for Wireless Fidelity - Otherwise known as Wireless Networking, commonly using the 802.11b or 802.11g protocol. In many Internet cafes, you can connect your laptop to the Internet via WiFi connection, provided that your laptop has WiFi support.
