Description

WiFi is a globally used wireless networking technology that uses the 802.11 standard. The term WiFi is an abbreviation of ‘wireless fidelity’. The technology used in WiFi was developed in 1997 by the Institute of Electrical and Electronics Engineers (IEEE). This technology was later commercialized by the Wi-Fi Alliance, a trade group.
The basic system of WiFi is very simple. In a WiFi enabled network, computers with WiFi cards connect wirelessly to an access point or router. This access point or router is internet enabled the usual way, connected to the internet using a cable or DSL modem. Any PC or laptop with a WiFi card, which is within a radius of 200 feet (60 meters) from the access point can access internet. However a distance of 100 feet (30 meters) is considered ideal for good quality access. An area surrounding an access point, providing wireless access, is called a wireless hotspot.
