Wi-Fi

A Wi-Fi enabled device such as a personal computer, mobile phone, MP3 player orvideo console can connect to the Internet when within range of a wireless network connected to the Internet. The coverage of one or more interconnected access points — called a hotspot — can comprise an area as small as a few rooms or as large as many square miles covered by a group of access points with overlapping coverage. Wi-Fi technology has been used in wireless mech networks as well.
