WiFi, or Wireless Fidelity, is also referred to as "802.11b", "802.11g" and "802.11a" after the IEEE standards it utilises. WiFi is a wireless equivalent of the common Ethernet (a wired network). Anyone can set up a WiFi network and cover an area of typically 100-500 feet with high speed wireless access to a LAN, and hence to the Internet.

Like Bluetooth™ WiFi offers the opportunity for devices to communicate in a local environment, although over a larger distance.
