Wi-Fi

✨ The invisible link

Wi-Fi is a wireless communication technology that allows electronic devices to connect to the internet or exchange information without using physical cables. It works by transmitting data through radio waves between a device, such as a smartphone or computer, and a wireless router connected to a network.

The name Wi-Fi refers to a family of technical standards that define how these wireless connections operate. Wi-Fi is used in homes, schools, businesses and many public places to provide internet access to different devices at the same time.

Its speed and range depend on several factors, including the equipment used, the distance from the router and obstacles such as walls. Over time, Wi-Fi technology has improved to offer faster connections and better performance.

Although it makes digital communication easier, a secure Wi-Fi network requires good practices, such as using strong passwords and keeping devices updated.

💡 Did you know?

Did you know that the word Wi-Fi technically means nothing? Many think it's short for 'Wireless Fidelity,' but it's a brand invented by advertisers! They wanted a short, catchy name to replace the very complicated scientific term (IEEE 802.11b) used to designate this technology.

Some objects in your home can disrupt your Wi-Fi! Concrete walls, mirrors, or even the microwave oven can slow down the signal. Microwaves sometimes use the same frequency as Wi-Fi, which creates interference. This is why it is recommended to place the router in the middle of the room, in plain sight.

The inventor of wireless internet was an actress! Hedy Lamarr, a very famous movie star from the 1940s, invented a secret system to guide torpedoes during the war without them being jammed. It was her 'frequency hopping' technique that later allowed for the invention of Wi-Fi and Bluetooth!
