What is WiFi and how does it work?

You probably use WiFi almost all the time, but have you ever figured out what WiFi really is?

WiFi is a term that gets thrown around a lot, but what does that mean? WiFi is a form of wireless local area network and internet access that people all over the world use to connect their devices to the internet wirelessly.

This article will help you understand what WiFi is, how it works, and more.

What does WiFi mean?

WiFi is generally thought to mean “wireless fidelity”, but the term “WiFi” was coined as a result of an attempt to come up with a more attractive name for the newly innovative wireless technology which until then was referred to as “IEEE 802.11 Direct Serial”.

according to Wikipedia And some other sources, the term “WiFi” means nothing. It was a name that brand consultancy Interbrand invented, after it contracted with the WiFi Alliance to come up with a name for its new wireless technology. It was never intended to be an abbreviated form of wireless fidelity.

There is an explanation for a misunderstanding of what WiFi means. The misunderstanding arose as a result of the advertising slogan used by the WiFi Alliance shortly after the WiFi name was adopted: “The Wireless Fidelity Standard”.

What is Wi-Fi?

WiFi is a wireless network technology that allows you to connect wirelessly to the Internet. Also known as 802.11, it is the IEEE standard for wireless local area networks (WLAN).

WiFi networks operate in the unlicensed 2.4 GHz and 5 GHz frequency bands, which means that they do not interfere with other nearby wireless networks operating on the same frequency (or bandwidth).

How does WiFi work?

Modern WiFi networks work the same way as wired Ethernet (LAN) connections. The only difference is that they use unlicensed spectral frequencies to transmit data over short distances at high speeds, such as mobile broadband.

The WiFi standard was developed by the Institute of Electrical and Electronics Engineers (IEEE) to provide wireless access within a local area, usually within a home or office building.

For WiFi to work, an access point (base station) must be available with a wired connection to connect WiFi devices. WiFi devices connect to access points using radio frequency (RF) signals, such as a cordless phone.

How is WiFi used?

WiFi provides a wireless alternative to wired networks for sharing data between devices within the same building or area, such as laptops and smartphones connected to an internet router for file sharing.

It also replaces the cable that runs from your computer directly to your router or internet modem, allowing you WiFi access to the internet via a WiFi hotspot.

What is a WiFi hotspot?

A WiFi hotspot is a site with wireless Internet access, usually free. You can find them in cafes or restaurants that provide services for the convenience of customers.

WiFi networks are also found in airports, hotels, and other public places provided for the convenience of customers. Some WiFi hotspots are provided by WiFi providers that allow you to connect for a fee, while others are free WiFi connections.


So what is WiFi? Simply put, WiFi is a local area network or LAN (Local Area Network) that does not require cables for its communication media. WiFi has become a basic necessity in our lives. We’ve covered the basics of WiFi and how it works in this article. We hope you now know what WiFi is.
