Abstract

WiFi—an acronym for wireless fidelity (wireless)—encompasses a number of standards that enable computers and other devices to connect wirelessly to local area networks. A number of organizations have chosen to make WiFi access freely available to any who would wish to connect. WiFi fits in a family of standards developed under the IEEE (I-triple-E) or The Institute of Electrical and Electronics Engineers. The IEEE is a standards body that developed the 802 family of standards. These standards describe a framework—physical media and the working characteristics—that would enable two or more devices to communicate within a network. Most notable of" these standards is the 802.3 standard, the specification for Ethernet. The Ethernet standard describes a method of physical communication in a local area network (LAN).A wide majority of computer networks now employ Ethernet as their communication standard; almost every computer sold includes an Ethernet jack for connecting to an Ethernet network.
