    Wi-Fi stands for Wireless Fidelity which is simply a marketing term to distinguish it from cellular wireless Internet.

    Wireless Internet allows you to connect to the Internet, you guessed it ... without any wires! The idea is that you take one broadband Internet connection such as DSL or Cable or Satellite, then you attach a 'Wireless Access Point' (WAP) which transmits the signal thru the airwaves, using radio signals. If another computer is equipped with a wireless adapter (a little antenna), they can pick up this signal and, Voila! They're on the Internet.

    Wi-Fi (also WiFi, wifi, etc.) is a brand originally licensed by the Wi-Fi Alliance® to describe the underlying technology of wireless local area networks (WLAN) based on the IEEE 802.11 specifications. It was developed to be used for mobile computing devices, such as laptops, in LANs, but is now increasingly used for more services, including Internet and VoIP phone access, gaming, and basic connectivity of consumer electronics such as televisions and DVD players, or digital cameras.

    More standards are in development that will allow Wi-Fi to be used by cars in highways in support of an Intelligent Transportation System to increase safety, gather statistics, and enable mobile commerce (see IEEE 802.11p). Wi-Fi® and the Wi-Fi CERTIFIED™ logo are registered trademarks of the Wi-Fi Alliance® - the trade organization that tests and certifies equipment compliance with the 802.11x standards.

    Take a look at links provided for more indepth information.

  • Short for wireless fidelity and is meant to be used generically when referring of any type of 802.11 network, whether 802.11b, 802.11a, dual-band, etc. The term is promulgated by the Wi-Fi Alliance.

    Any products tested and approved as "Wi-Fi Certified" (a registered trademark) by the Wi-Fi Alliance are certified as interoperable with each other, even if they are from different manufacturers. A user with a "Wi-Fi Certified" product can use any brand of access point with any other brand of client hardware that also is certified. Typically, however, any Wi-Fi product using the same radio frequency (for example, 2.4GHz for 802.11b or 11g, 5GHz for 802.11a) will work with any other, even if not "Wi-Fi Certified."

    Formerly, the term "Wi-Fi" was used only in place of the 2.4GHz 802.11b standard, in the same way that "Ethernet" is used in place of IEEE 802.3. The Alliance expanded the generic use of the term in an attempt to stop confusion about wireless LAN interoperability.

    Wi-Fi (short for "wireless fidelity") is a term for certain types of wireless local area network (WLAN) that use specifications in the 802.11 family. The term Wi-Fi was created by an organization called the Wi-Fi Alliance, which oversees tests that certify product interoperability. A product that passes the alliance tests is given the label "Wi-Fi certified" (a registered trademark).

    # Allows LANs to be deployed without cabling, typically reducing the costs of network deployment and expansion. Spaces where cables cannot be run, such as outdoor areas and historical buildings, can host wireless LANs.

    # Wi-Fi silicon pricing continues to come down, making Wi-Fi a very economical networking option and driving inclusion of Wi-Fi in an ever-widening array of devices.

    # Wi-Fi products are widely available in the market. Different brands of access points and client network interfaces are interoperable at a basic level of service. Products designated as Wi-Fi CERTIFIED by the Wi-Fi Alliance are interoperable and include WPA2 security.

    # Wi-Fi networks support roaming, in which a mobile client station such as a laptop computer can move from one access point to another as the user moves around a building or area.

    # Wi-Fi is a global set of standards. Unlike cellular carriers, the same Wi-Fi client works in different countries around the world.

    # Widely available in more than 250,000 public hot spots and millions of homes and corporate and university campuses worldwide.

    # As of 2006, WPA and WPA2 encryption are not easily crackable if strong passwords are used

    wifi is electronic equipment communicating with wires/cables etc. cell phones are an example (not called wifi, but the same principle)

    a radio signal is sent and received thereby allowing the two pieces of equipment to communicate. examples are bluetooth-good to approximately 30 feet to the wifi some cities are setting up that covers the entire city. it depends on frequency and, more importantly, power.

    No apple units comprise equipped in wifi. that only signifies that the iPad itself is like minded with wifi. also, there are 2 different variations of the iPad 2: 3G and Wifi. 3G is able to connect with AT&T's 3G community and wifi desires a wifi hotspot to get admission to the internet.

    It's a made-up marketing name for wireless networking. It's not internet access per-se, just wireless ethernet.
