The onset of a digital era has brought about a myriad of inventions. One of the most commonly used technologies is the Wi-Fi. While millions of people use Wi-Fi every day, we can bet there is little knowledge about what exactly it is and how it works. Upending traditional networking methods, Wi-Fi carries a whopping 60% of internet traffic from all over the world.
What is Wi-Fi?
Wi-Fi stands for wireless fidelity. As the name suggests, it provides a wireless internet connection that uses radio frequencies to transmit signals between devices. Also known as Wireless Local Area Network (WLAN), Wi-Fi is actually a simpler term for its technical name, IEEE 801.11 technology.
How does it Work?
The main purpose of a Wi-Fi network is to provide connectivity to all devices connected to it. As mentioned above, Wi-Fi uses radio waves to operate. Radio waves are a type of electromagnetic radiation. Wi-Fi transmits and receives these radio waves in the Gigahertz range.
Wi-Fi requires a frequency of 2.4 Ghz to 5Ghz to perform optimally. There are a whole lot of invisible radio waves working to allow you to stream your favorite show with ease.
Benefits of Wi-Fi
Wireless networking is a burgeoning trend these days, owing to its convenience. One of the most obvious benefits of Wi-Fi is its wireless quality, rendering it a mobile way to stay connected, anywhere you may be.
Wi-Fi connections are affordable and easy to set, which explains why every household will most likely have a working Wi-Fi connection.
Wi-Fi is a popular choice as it ensures security. To avoid random people from using your personal connection, you can set a password to unlock WPA2, or Wi-Fi Protected Access. If you want to allow someone to connect to your Wi-Fi, you may open your ‘hotspot’,
Among the innumerable technological advances, Wi-Fi is undoubtedly one of the most useful inventions, allowing seamless connectivity.
