What is WiFi?

Wi-Fi is commonly believed to be short for Wireless Fidelity but is actually not true. The term was made by a marketing firm called Interbrand, who also created the WiFi logo. The wireless industry was trying to look for a more user-friendly name to refer to the not so user-friendly technology known as IEEE 802.11. A founding member of the Wi-Fi Alliance, Phil Belanger, who presided over the selection of the name for IEEE 802.11 stated that Interbrand actually invented Wi-Fi as a pun upon the word hi-fi.

WiFi is a technology that makes use of radio waves to provide network connectivity. For a lot of people, the term Wi-Fi has become synonymous with “Internet”. To be more accurate, WiFi is a wireless connection standard. The Internet is a data or the language, while Wi-Fi is the wireless network technology which sends the data via internet connections through the air to wide area networks and on to the non-wired computers.

WiFi networks, like mobile phones, uses radio waves to transmit information across a network. The device should have a wireless adapter which will translate the data sent into a radio signal. The radio signal will then be transmitted, via an antenna, to a decoder known as the router. Once the signal has been decoded, the data will be sent to the Internet through a wired ethernet connection. As the WiFi network works like a two-way traffic, the data received from the internet will go through the router to be coded as radio signals which will be received by the computer’s wireless adapter.

An internet connection is established using a wireless adapter to create hotspots. The term hotspot means an area where a WiFi access is available. It may either be through a closed wireless network at home or in public places such as malls or restaurants. One of the advantages of WiFi is that it is compatible with almost every computer, mobile phones, operating systems, and gaming devices.
