What is WiFi?

Wireless Fidelity (WiFi) is a technology that allows wireless connection between a computer and the Internet, as well as between devices (for example, between a computer and a printer). Data is transmitted at high speed thanks to radio waves.

The WiFi appellation is actually a registered trademark formerly Wireless Ethernet Compatibility Alliance. Simpler to remember, the name WiFi is now also used in everyday life to refer to the IEEE 802.11 standard. In some countries, such as Germany or the United States, the term Wireless Local Area Network (WLAN) is also used.

What is WiFi for?

WiFi connects a device to the Internet or other wireless device. One of the main advantages is to offer users greater mobility. Thanks to WiFi, you do not need to be connected to a cable to access the Internet. It is possible to move freely anywhere in the covered area.

How does WiFi work?

For a WiFi connection to work, it is necessary to have a router and a device (computer, smartphone,) equipped with a wireless network adapter that will convert the data sent into a radio signal. These will then be transmitted to the router through a radio antenna.

During a WiFi connection, the data is transmitted bidirectional that is to say from the equipped device to the router, but also from the Internet to the router. In the second case, it is the wireless adapter of the device that will receive the data.

Wireless communication is established via radio waves. To enjoy a good quality WiFi, the ideal would be to have no other electrical devices emitting waves to avoid interference. The closer the receiver and transmitter are, the faster the flow will be.
